Detailed description of the invention
Below in conjunction with accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Generally can with various different configurations arrange and design with the assembly of the embodiment of the present invention that illustrate described in accompanying drawing herein.Therefore, below the detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit claimed the scope of the present invention, but is merely representative of the selected embodiment of the present invention.Based on embodiments of the invention, the every other embodiment that those skilled in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention.
In alternating current circuit, active power refers to the meansigma methods of the integration sending the instantaneous power with load consumption in the cycle or the power of load resistance consumption.Reactive power, is the capacitive due to load or inductance characteristic, i.e. non-pure resistance, is stored by a part of electric energy, and the energy of this part storage is reactive power.In power system, the change of the reactive power of equipment is relevant with the change in equipment magnetic field, being described below by object lesson: set and have N group equipment in a Factory Building, often group equipment has an independent fan to come the cooling of this equipment and dehumidifying, and fan substantially uses and uses motor.Refer to Fig. 1, be the structure chart of motor, the principle of motor is, when sinusoidal current is by stator winding, motor will produce an alternating magnetic field, and sinusoidal rule change is done in the power in this magnetic field and direction in time.This magnetic field can be analyzed to two with the contrary each other rotating excitation field of same rotational speed, direction of rotation, and when stationary rotor, the two rotating excitation field produces two torques equal in magnitude, in opposite direction in the rotor, makes synthesis torque is zero, so motor cannot rotate；When there being external force to make motor rotate to some direction, at this moment the cutting magnetic line movement between the rotating excitation field in rotor and the direction that turns clockwise diminishes, and electromagnetic torque produced by rotor will be no longer zero, and rotor will rotate along pushing direction.
For N group equipment, often group equipment uses active power to be pi(for multimode equipment, piThe mean power after this opening of device), reactive power be qi。
The surface temperature of electrical equipment is ti, the active power of electric motor temperature reduction equipment is pmi, reactive power is qmi, in equipment real process, the active power of core circuit is pi-pmi, reactive power is qi-qmi.Work as qmiTime more big, namely two rotating excitation field differences of motor-field are more big, and the motor speed of electrical equipment is more fast, and namely electrical equipment load T is excessive, and it is more big that heat sheds.Work as qmiMore hour, namely two rotating excitation field differences of motor-field closer to, it is judged that the motor speed of electrical equipment is more slow, and namely electrical equipment load T is more little, and it is more little that heat sheds.Magnetic field difference and reactive power qmiRelation as shown in Figure 2.Therefore the relation of reactive power and load temperature is drawn, as shown in Figure 3.
It can be seen that when the reactive power accounting of electrical equipment N is more big, the load of this electrical equipment is more big, the heat that circuit board sheds is more many, and then has influence on temperature ti.In sum, the size of reactive power influences whether the heat dispersal situations of equipment, when reactive power is more big, the heat that then equipment distributes is more big, and then the temperature in closed interval rises more fast, when reactive power is more little, the heat that then equipment distributes is more little, and then the temperature in closed interval rises more slow.Theoretical based on this, embodiments provide a kind of mode by electric power datas such as reactive powers on detection electrical bus and manage system, method and device to reach energy-conservation electric power energy-saving.
Refer to Fig. 4, be the system architecture schematic diagram of the electric power energy-saving management system 100 that the embodiment of the present invention provides.This electric power energy-saving management system 100 includes data acquisition unit 110, server 120 and control unit 130.Data acquisition unit 110 includes electric energy management terminal 111, sets up communication connection between electric energy management terminal 111 and server 120, and server 120 sets up communication connection with control unit 130.Electric energy management terminal 111 can be single-phase electric energy management terminal, it is also possible to be three-phase electric energy management terminal.The number of electric energy management terminal 111 can be single, it is also possible to for multiple.
