Description
Technical field
The utility model relates to the adjusting of generator set.
Background technique
Generator set is made of the assembly of a motor and an alternator.For a voltage rating and frequency are provided, motor and alternator all are equipped with controlling device.Motor is equipped with a velocity of electrons regulator in the fuel injection system that is integrated into this motor.Except other things, the adjusting of engine speed can be depended on the measured value of the rotational speed of engine shaft, for example by a sensor in the per time unit one have the ring gear of tooth to count in the number of teeth of this sensor front process.
By the signal that is sent by this sensor, thereby the injection computer of speed regulator has been determined the level of spraying speed has been remained on the predetermined value, but the immediate knowledge that does not have the load level that is applied on this motor is not because also exist economic means to come for this load level is informed computer.
Be applied to each variation of the load on this motor, no matter it is to increase or reduce, and all can cause instantaneous minimizing or the increase of this engine revolution (speed regulator is attempted to come it is proofreaied and correct by a suitable injection level).
In known generator set, only be the knowledge by speed and injection level, this speed regulator has just determined to be applied to this load level on the motor.
To the desired moment of torsion C of motor be directly and the electric current I of output place of alternator proportional.In fact, the law of the power P of motor is:
P=C.w，
Wherein, w is the rotational speed of motor.
The power law P of alternator is:
Wherein, U is the output voltage of alternator, and
It is the phase shift between electric current I and the voltage U.
Motor is that mechanical type is connected with alternator, and within coupling efficiency, it just might be written as:
Applying in the process of a big useful load,
Become close to 1, and the voltage of alternator descends.Alternator is equipped with a voltage regulator, and this voltage regulator is proofreaied and correct this voltage rapidly by increase electric current in the magnetic pole wheel and descended.
This variation in the load also causes the decline of speed, because the desired moment of torsion C of motor has been increased.This requirement that do not make an immediate response of motor ability, its speed w descends, and this is because the part of moment of torsion C is to extract from the deposit of rotation function.
In fact, how help to be applied on this motor rapidly with this voltage regulator be condition to the mode that motor is gathered way.
The turbosupercharger motor is just used in generator set more and more.A shortcoming of such motor is can demote if turbosupercharging can not correctly be activated so its performance.
Now, the great change meeting of load tends to make with regard to the true(-)running of motor excessive engine to slow down.In idle process, the pressure of suction port is close to atmospheric pressure, in case and the increase of load is applied on the generator set, the speed of this motor just drops on such point, no matter that is: speed regulator reacts at ejecting system, exhaust stream all is not enough to this or these turbine of these turbosupercharger is started in their operation conditions.So their abilities increase suction pressure, and this increase is desired in order to make this motor have the ability to accelerate and return to its rated velocity.Therefore, have a non-return point, in this requirement is to avoid reaching this point.
In a kind of known mode, it is that speed at motor has descended and its speed applies when having fallen to being lower than a certain numerical value that this motor helps.
Known from patent US 5 703 410, field current and the fuel of monitoring alternator based on the knowledge of the voltage of the rectification of output place of this alternator spray.
Also known from application EP 1 938 447, when detecting a load variations, send the fuel suction actuator that a control signal (it has replaced the output signal of speed regulator) is controlled generator set by monitoring device.
Exist a kind of performance that requires further to improve generator set, especially in the process that load increases, in order to assist the use of turbosupercharger motor except other things.
