Description

Technical Field

The present invention relates to energy technology, and is especially one kind of AC/DC combined power generating system.

Background

As is known, motors, also known as electric motors or electric motors, are capable of converting electrical energy into rotational mechanical energy. The electric motors are widely used, but they can be broadly divided into ac motors and dc motors for various applications, among which induction motors and disc motors are widely used as conventional motors. In contrast to an electric motor, a generator can convert rotational mechanical energy into electrical energy. More specifically, the generator utilizes various power (e.g., water power, wind power) to drive the main shaft to rotate, so that the coil rotates between two poles of the magnet, thereby changing the magnetic field in the coil and generating an induced current. The generator is widely used, but can be broadly divided into an ac generator and a dc generator to be used in different applications, wherein a small wind power generation system is generally equipped with a disk generator, and an induction generator is widely used in a green power generation system.

Practical experience has shown that both alternators and dc generators have their advantages, but they also have their disadvantages and drawbacks in their use. Accordingly, the present inventor has made extensive research and creation, and finally completed the present invention.

In order to more clearly describe the ac/dc hybrid power generation system of the present invention, the following description will be made in detail with reference to the drawings.

Basic structure of alternating current/direct current combined type power generation system

Please refer to fig. 1, which is a schematic diagram of a basic structure of an ac/dc hybrid power generation system according to the present invention. As shown in fig. 1, the ac/dc hybrid power generation system 1 includes: a first dc power generation module 11, a first ac power generation module 12 and a first transmission module 1T1, wherein the first dc power generation module 11 includes a first dc power generator 111, a first rotating shaft 112 and M first flywheels 113. More specifically, the first rotating shaft 112 has a first end and a second end, and the first end is dynamically coupled to the rotating shaft of the first dc generator 111. Moreover, the M first flywheels 113 are sleeved on the first rotating shaft 112. On the other hand, the first ac power generation module 12 includes a first ac generator 121, a second rotating shaft 122 and N second flywheels 123. As shown in fig. 1, the second rotating shaft 122 has a first end and a second end, and the first end is dynamically coupled to the rotating shaft of the first ac generator 121. Moreover, the N second flywheels 123 are sleeved on the second rotating shaft 122.

Fig. 1 also shows that the first dc power generation module 11 further includes M-1 first gearboxes 114, wherein the M-1 first gearboxes 114 are all sleeved on the first rotating shaft 112, and any one of the first gearboxes 114 is disposed between two first flywheels 113. On the other hand, fig. 1 also shows that the first ac power generating module 12 also includes N second gearboxes 125, wherein the N second gearboxes 125 are all sleeved on the second rotating shaft 122, and any one of the second gearboxes 125 is adjacent to one of the second flywheels 123.

As shown in fig. 1, the first transmission module 1T1 is power coupled between the first rotating shaft 112 and the second rotating shaft 122. In other words, the first dc power generation module 11 and the first ac power generation module 12 realize parallel power coupling through the first rotating shaft 112, the second rotating shaft 122 and the first transmission module 1T 1. After a first starter motor is used to start the first dc generator 111, the first dc generator 111 is operated to generate power and drives the first ac generator 121 to generate power. Similarly, a second starter motor can be used to start the first ac generator 121 to generate power and drive the first dc generator 111 to generate power. Finally, the electric power generated by the first alternator 121 is stored in a battery device 6. In addition, the power generated by the first ac generator 121 can also be provided to a load device 5. In a possible embodiment, the load device 5 may be an electromechanical device or an electronic device, receiving power directly from the first alternator 121. On the other hand, a starter motor control circuit is coupled to the first starter motor and the second starter motor, and the starter motor control circuit is coupled to the battery device 6 at the same time, so as to utilize the electric energy stored in the battery device 6. Further, the battery device 6 has an Energy Management System (EMS) and a plurality of batteries, and the Energy management system schedules a charging process for each battery after receiving power from the first alternator 121. In addition, the energy management system can also provide the dc power of the battery device 6 to the first dc generator 111 to form feedback power.

In another possible embodiment, the starting motor control circuit is further coupled to a power backup device. Thus, before the power storage device stores the stored power, the starter motor control circuit first uses the power provided by the power backup device to control the first starter motor to power the first dc generator 111 for dc power generation and/or control the second starter motor to power the first ac generator 121 for ac power generation.

It should be appreciated that the gearbox may adjust the rotational speed of the rotating shaft according to a rotational speed ratio (or reduction ratio). For example, in the first dc power generation module 11, the first gearbox 114, labeled C1, adjusts the rotational speed to 2400RPM, and the first gearbox 114, labeled C2, adjusts the rotational speed even further to 600RPM. Correspondingly, in the first alternator module 12, the second gearbox 125, labeled C3, adjusts the rotational speed to 600RPM, and the second gearbox 125, labeled C4, adjusts the rotational speed even further to 150RPM. Therefore, it can be understood that the rotation speed of the second rotating shaft 122 and the first rotating shaft 112 at the power coupling (i.e., the first transmission module 1T 1) is 150RPM. Motor engineers familiar with motor design must know that with a gearbox to bring the RPM down from 4000RPM to 1000RPM, the torque increases by a factor of 4 correspondingly.

As shown in fig. 1, a rotation speed adjusting device 1S is connected to each of the first flywheel 113 and the second flywheel 123. Fig. 2 is a first configuration diagram of the rotational speed adjustment apparatus 1S shown in fig. 1. In an embodiment, the rotation speed adjusting device 1S may be a magnetic rotation speed adjusting mechanism, and includes: a coil 1S1a, a controller 1S2a electrically connected to the coil 1S1a, a moving shaft 1S0a horizontally and laterally moving in the coil 1S1a, and a first magnet 1S3a, a second magnet 1S4a, a first high magnetic flux magnet 1S5a and a second high magnetic flux magnet 1S6a fitted over the moving shaft 1S0 a. Specifically, the controller 1S2a generates a PWM current signal to be transmitted to the coil 1S1a, so that the coil 1S1a generates a high-speed changing magnetic pole changing with the PWM current signal to act on the first magnet 1S3a, the second magnet 1S4a, the first high-magnetic-flux magnet 1S5a, and the second high-magnetic-flux magnet 1S6a, thereby moving the moving shaft 1S0a left/right, thereby realizing the magnetic rotation speed adjustment.

On the other hand, fig. 3 is a second structural diagram of the rotational speed adjustment device 1S shown in fig. 1. In another embodiment, the rotation speed adjusting device 1S may be a valve-type rotation speed adjusting mechanism, and includes: a valve body 1S0b, a first piston rod 1S1b, a second piston rod 1S2b, a first fluid controller 1S3b, a second fluid controller 1S4b, a left-end high magnetic flux magnet 1S5b, and a right-end high magnetic flux magnet 1S6b. It is easy to understand that the first fluid controller 1S3b and the second fluid controller 1S4b are used to control the flow of a fluid (e.g., gas) into/out of the valve body 1S0b, thereby modulating the lateral movement distance of the first piston rod 1S1b and/or the second piston rod 1S2 b. And, the first piston rod 1S1b and the second piston rod 1S2b will generate a force of 1-10000 n/m when moving laterally, thereby realizing the valve body type rotational speed adjustment. Specifically, the first fluid controller 1S3b controls the high-pressure gas to flow into the valve body 1S0b, and the high-pressure gas is used to push the first piston rod 1S1b and the second piston rod 1S2b to move inwards, so that the space between the two piston rods is reduced. Further, the second fluid controller 1S4b controls the flow of high-pressure gas into the valve body 1S0b, the high-pressure gas flowing into the space between the first piston rod 1S1b and the second piston rod 1S2b, thereby pushing the first piston rod 1S1b and the second piston rod 1S2b to the left and right, respectively.

Advanced structure of AC/DC combined power generation system (1)

Please refer to fig. 4, which is a first schematic diagram of an advanced architecture of an ac/dc hybrid power generation system according to the present invention. As shown in fig. 4, the advanced architecture of the ac/dc hybrid power generation system 1 includes: a first dc power generation module 11 (for example, a hydraulic low-speed motor driving a generator to generate power), a first ac power generation module 12, a first transmission module 1T1, a second dc power generation module 13, a second transmission module 1T2, a second ac power generation module 14, a third transmission module 1T3, and a fourth transmission module 1T4. In a further architecture, the second dc power generation module 13 includes: a second dc generator 131, a third rotating shaft 132 and L third flywheels 133, wherein the third rotating shaft 132 has a first end and a second end, and the first end is coupled to the rotating shaft of the second dc generator 131. Moreover, the L third flywheels 133 are sleeved on the third rotating shaft 132, and the second transmission module 1T2 is coupled to the first rotating shaft 112 and the third rotating shaft 132 through power. It should be noted that, in the advanced configuration, the first ac power generating module 12 further includes N fourth flywheels 124, which are disposed on the second rotating shaft 122 and are adjacent to the second transmission module 1T2.

As shown in fig. 4, the second ac power generation module 14 includes: a second ac generator 141, a fourth rotating shaft 142 and K fifth flywheels 143, wherein the fourth rotating shaft 142 has a first end and a second end, and the first end is coupled to the rotating shaft of the second ac generator 141. Moreover, the K fifth flywheels 143 are sleeved on the fourth rotating shaft 142. Meanwhile, fig. 4 also shows that the third transmission module 1T3 is power-coupled between the fourth rotating shaft 142 and the first rotating shaft 112, and the fourth transmission module 1T4 is power-coupled between the fourth rotating shaft 142 and the third rotating shaft 132. It is noted that, in the advanced configuration, the second ac power generation module 15 further includes K sixth flywheels 144, which are disposed on the fourth rotation shaft 142 and adjacent to the fourth transmission module 1T4.

Fig. 4 also shows that the first ac generating module 12 further includes: n-1 third gearboxes 126 are all sleeved on the second rotating shaft 122, and any one of the third gearboxes 126 is arranged between two fourth flywheels 124. On the other hand, the second dc power generation module 13 further includes: l-1 fourth gearboxes 134 are all sleeved on the third rotating shaft 132, and any one of the fourth gearboxes 134 is located between the two third flywheels 133. The second ac power generation module 14 further includes: k fifth transfer cases 145 and K-1 sixth transfer cases 146. As shown in fig. 4, the K fifth gearboxes 145 are all sleeved on the fourth rotating shaft 142, and any one of the fifth gearboxes 145 is adjacent to one of the fifth flywheels 143. Moreover, the K-1 sixth gearboxes 146 are all sleeved on the fourth rotating shaft 142, and any one of the sixth gearboxes 146 is interposed between the two sixth flywheels 144.

As shown in fig. 4, the second transmission module 1T2 is power coupled between the second rotating shaft 122 and the third rotating shaft 132, the fourth transmission module 1T4 is power coupled between the third rotating shaft 132 and the fourth rotating shaft 142, and the third transmission module 1T3 is power coupled between the fourth rotating shaft 142 and the first rotating shaft 112. In other words, the first dc power generation module 11, the first ac power generation module 12, the second dc power generation module 13 and the second ac power generation module 14 realize series/parallel power coupling through the first rotating shaft 112, the second rotating shaft 122, the third rotating shaft 132, the fourth rotating shaft 142, the first transmission module 1T1, the second transmission module 1T2, the third transmission module 1T3 and the fourth transmission module 1T4.

After a third starter motor is used to start the second dc generator 131, the second dc generator 121 operates to generate electricity and drive the first ac generator 121 and the second ac generator 141. Similarly, a fourth starting motor can also be used to start the second ac generator 141 to generate power, and drive the first dc generator 111 and the second dc generator 131 to generate power, and the second dc generator 131 drives the first ac generator 121 to generate power. Finally, the electric power generated by the first alternator 121 and the second alternator 141 is stored in a battery device 6. In addition, the power generated by the first ac generator 121 can also be provided to a load device 5. In a possible embodiment, the load device 5 may be an electric motor device or an electronic device, receiving power directly from the first alternator 121 and the second alternator 141. On the other hand, a starter motor control circuit is coupled to the first starter motor, the second starter motor, the third starter motor, and the fourth starter motor, and the starter motor control circuit is also coupled to the battery device 6, so as to utilize the electric energy stored in the electric energy storage device. Further, the power storage device has an Energy Management System (EMS) and a plurality of batteries, and the EMS schedules a charging process for each battery after receiving power from the first dc generator 111 and/or the first ac generator 121. In addition, the energy management system can also provide the dc power of the battery device 6 to the first dc generator 111 and the second dc generator 131 to form feedback power.

In another possible embodiment, the starting motor control circuit is further coupled to a power backup device. Thus, before the power storage device stores the stored power, the starter motor control circuit first uses the power provided by the power backup device to control the first/second/third/fourth starter motor to power the first dc generator 11/the first ac generator 111/the second dc generator 12/the second ac generator 121 for generating power.

It should be appreciated that the gearbox may adjust the rotational speed of the rotating shaft according to a rotational speed ratio (or reduction ratio). For example, in the second dc power generation module 13, the fourth transmission 134 denoted by C6 adjusts the rotation speed to 150RPM, the fourth transmission 134 denoted by C7 adjusts the rotation speed to 600RPM, the fourth transmission 134 denoted by C8 adjusts the rotation speed to 2400RPM, and the fourth transmission 134 denoted by C8 adjusts the rotation speed to 9600RPM. Correspondingly, in the second alternator module 14, the fifth gearbox 145, denoted C10, adjusts the rotational speed to 600RPM, and the fifth gearbox 145, denoted C11, adjusts the rotational speed to 150RPM. Motor engineers familiar with motor design must know that with a gearbox to bring the speed down from 4000RPM to 1000RPM, the torque increases by a factor of 4 correspondingly.

As shown in fig. 4, in addition to the first flywheel 113 and the second flywheel 123 both connected with a rotation speed adjustment device 1S, the third flywheel 133, the fourth flywheel 124, the fifth flywheel 143, and the sixth flywheel 144 are also connected with a rotation speed adjustment device 1S. It will be appreciated that different flywheels have their rotational speeds adjusted by different gearboxes. More specifically, the magnetic-type rotation speed adjustment mechanism (i.e., the rotation speed adjustment device 1S) shown in fig. 3 can adjust the rotation speed of the flywheel within a rotation speed range of 3000 to 9000 RPM. On the other hand, the valve-type rotation speed adjustment mechanism (i.e., the rotation speed adjustment device 1S) shown in fig. 4 can adjust the rotation speed of the flywheel within the rotation speed range of 150 to 600RPM. It should be noted that a feedback circuit may be coupled to the battery device 6, so as to utilize the power stored in the battery device 6 and generate a PWM current signal to the coil 1S1a of each of the rotational speed adjusting devices 1S, or generate a gas valve control signal to the first fluid controller 1S3 b/the second fluid controller 1S4b of the rotational speed adjusting devices 1S.

Advanced structure of AC/DC combined power generation system (2)

Please refer to fig. 5, which is a second schematic diagram of an advanced architecture of an ac/dc hybrid power generation system according to the present invention. As shown in fig. 5, the advanced architecture of the ac/dc hybrid power generation system 1 includes: a first engine 21, an alternator 22, a second engine 23, a main shaft 20, a first flywheel 24, a second flywheel 25, and two third flywheels 26. The main shaft 20 is sequentially coupled to the first engine 21, the alternator 22 and the second engine 23, such that the first engine 21, the alternator 22 and the second engine 23 are coupled in series via the main shaft 20. On the other hand, the first flywheel 24 is disposed on the main shaft 22 and between the first engine 21 and the alternator 22. The second flywheel 25 is disposed on the main shaft 22 and between the alternator 22 and the second engine 23. Furthermore, the two third flywheels 26 are disposed on the main shaft 22 and between the second engine 23 and the tail end of the main shaft 20.

In one embodiment, the first engine 21 is an eight cylinder engine that is started with a coil-driven engine (i.e., ignition coil) and operated by an input pulsed direct current. On the other hand, the second engine 23 is an eight-cylinder gas engine that is driven by the energy of combustion of hydrogen gas. As shown in fig. 5, a rotation speed adjusting device 1S is also connected to each of the first flywheel 24, the second flywheel 25, and the two third flywheels 26.

When the ac/dc hybrid power generation system 2 is operating normally, the power (ac power) generated by the ac generator 22 can be transmitted to a Power Conversion System (PCS) 7. Motor engineers familiar with power system design should know that the energy storage inverter (PCS) 7 can be seamlessly switched from grid-connected to off-grid, when a power grid fails, the energy storage inverter 7 can quickly identify and quickly switch to an off-grid operation mode, and the switching time should be short enough to minimize the influence of the power grid failure on the load and power supply in the power supply system. Similarly, the power generated by the alternator 22 can be stored in a battery device 6, and a feedback circuit 8 is coupled to the battery device 6, so as to generate a first engine control signal to the first engine 21, a second engine control signal to the second engine 23, and a PWM current signal to the coil 1S1a of each of the speed adjusting devices 1S, or a gas valve control signal to the first fluid controller 1S3 b/the second fluid controller 1S4b of the speed adjusting device 1S, by using the power stored in the battery device 6.

Combined type energy system

Please refer to fig. 6, which is a diagram of a hybrid energy system according to the present invention. As shown in fig. 6, the hybrid energy system 3 of the present invention mainly includes: a heat pump 31, an expander 32, an air compressor 33, a main shaft 30, and a power generation system 9, wherein the power generation system 9 can be an ac/dc hybrid power generation system of the present invention as shown in fig. 1, fig. 4 or fig. 5, or can be a turbine generator set. In one embodiment, the heat pump 31 comprises a hydrogen storage material, such as a TiFe alloy, a Ti [ Cr, mn ] alloy, or a LaNi5 alloy, and the chemical energy generated by the hydrogen absorption and desorption reaction of the hydrogen storage material can be effectively converted into heat energy, thereby generating a thermal fluid. The expander 32 is coupled to the heat pump 31 by a pipeline, so that the hot fluid flows into the expander 32. It is noted that the main shaft 30 is sequentially and dynamically coupled to the main shaft 20 (as shown in fig. 5), the rotating shaft of the expander 32, and the rotating shaft of the air compressor 33. In this arrangement, as the thermal fluid expands in volume within the expander 32, energy is converted so that the expander 32 has a mechanical energy coupled to the shaft 30. Thereafter, the main shaft 30 rotates to rotate the rotary shaft of the expander 32 and the rotary shaft of the air compressor 33. In a practical embodiment, the expander 32 can expand the fluid by 1-10000 times, thereby driving the power generation system 9 to operate to generate power.

As shown in fig. 6, the mechanical energy of the expander 32 can be further contributed to the main shaft 20 of the ac/dc hybrid power generation system 2 shown in fig. 5, so as to drive the second engine 23 to operate and drive the alternator 22 to operate jointly. On the other hand, the air compressor 33 is operated to compress and store the external ambient air into the plurality of first air storage tanks 34, so that the heat pump 31 obtains the air source for heat exchange from the plurality of first air storage tanks 34 through the pipeline. Further, fig. 6 shows that the hybrid energy system 3 of the present invention further includes: a hydrogen generator 35 coupled to a solar power supply 36 for receiving power and generating hydrogen by Proton Exchange Membrane (PEM) technology, and storing the generated hydrogen in a second air storage tank 37. On the other hand, fig. 6 shows that the power generated by the solar power device 36 can be stored in a battery device 6, and then the battery device 6 supplies power to the air compressor 33 to maintain the operation of the air compressor 33. Furthermore, the hybrid energy system 3 of the present invention further includes a pressurizing machine 39 having a heat collecting tube 38, and the heat collecting tube 38 is connected to a solar energy heat collecting plate 3A. Specifically, the solar heat collecting plate 3A collects heat energy to the heat collecting tube 38, and heats the heat medium flowing through the heat collecting tube 38, so that the heat medium is fed to the heat pump 31 through a pipeline while maintaining 350 ℃.

When the hybrid energy system 3 is operating normally, the electric power generated by the power generation system 9 is stored in a battery device 6. In addition, the power generated by the power generation system 9 can also be provided to a load device. In a possible embodiment, the load device may be an electrical device or an electronic device, which receives power directly from the ac/dc hybrid power generation system.

Thus, the above description is a complete and clear description of an AC/DC hybrid power generation system according to the present invention. It should be emphasized that the above detailed description is specific to possible embodiments of the invention, but this is not to be taken as limiting the scope of the invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the invention are intended to be included within the scope of the present invention.
