The speed regulation of diesel generator sets is of great significance. Assuming that the speed of the diesel generator is kept constant without a governor, the circulating fuel supply will change with the change of the speed when the load is high or low. When the load is reduced, the speed will increase. An increase in the circulating fuel supply will cause the diesel generator to exceed the extra speed and cause a runaway. When the load increases, the speed will drop and the circulating fuel supply will decrease, which will cause the diesel generator to fail to drive the load and stall.

Diesel generator set speed control can be divided into electronic speed control and mechanical speed control. The main difference between electronic speed control and mechanical speed control is that the effect of the centrifugal fly block and the speed control spring is replaced by current and voltage.

Share 4 kinds of diesel generator set speed regulation methods, 1. The adjustment of the starting speed, 2. The adjustment of the full load limit screw, 3. The adjustment of the idle speed stability spring, the effect of the idle speed stability spring is to assist in adjusting the sensitivity of the idle speed. 4. Stop the adjustment of the oil supply limit screw

Touching on a certain lack of diesel generators at that time, the research and analysis found out the diesel generator governor. Earlier diesel generator speed control was achieved by a mechanical governor, but its control accuracy was low and the processing speed was slow. Then the research announced The analog electronic governor successfully evolved from an analog electronic governor to a digital electronic governor in the 1980s. The electronic governor is composed of a speed sensor, a main control processor, and an actuator.

The research and analysis of the existing diesel generator electronic governor is based on the speed-azimuth double closed loop as the prototype. It relies on optimizing the electronic governor controller or using the speed-current double closed loop to operate the high and low speed of the diesel engine. The system continues to change the load. , Diesel generator speed will continue to be high and low, and diesel generator flywheel is attributed to large inertia energy storage parts, there must be lag and long adjustment time in the process of high and low speed, which will inevitably lead to high and low operating points in large areas. The non-linear characteristics of the dynamic process of the diesel generator are more obvious, and the fuel economy of the response control is not satisfactory.

Now that this situation is encountered, it is pointed out that the reaction control-reaction compound control is selected, and the feedforward control algorithm is drawn up. When the speed of the diesel generator does not change, the load change is recognized as soon as possible and the reaction is controlled to the diesel generator. This can not only greatly reduce the diesel generator. In the high and low speed area, the electromagnetic torque of the motor can also be increased to the required value in a short time, and the dynamic characteristics of the motor can be improved.
