Storage and gas generator additional control method, device, equipment and system

Abstract

The invention discloses a memory and a gas generator additional control method, device, equipment and system, and the method comprises the steps: obtaining a current rotating speed value of a generator in real time, and calculating a current rotating speed deviation according to a preset standard rotating speed value; according to the current rotating speed deviation, the opening adjustment amount of a throttle valve of the gas generator and / or the excitation control amount of an excitation system are / is calculated; an electronic control unit (ECU) generates a control instruction of the gas generator according to the opening adjustment amount and / or the excitation control amount; according to the method, the rotation speed adjustment of the gas generator and the adjustment of the excitation system are more timely and accurate, and the method has better robustness; therefore, the rotating speed of the gas generator can be stabilized in time, and the overall stable performance of the gas generator can be ensured.

Description

technical field [0001] The invention relates to the field of gas generators, in particular to a memory and an additional control method, device, equipment and system for gas generators. Background technique [0002] Gas-fired gas generators (referred to as gas generators) have been widely used in microgrids. When a single or multiple gas-fired generator sets are running in isolation with load, the system disturbance caused by load changes, line faults or other factors will often induce the gas-fired generator to lose its stable state, and slightly cause the voltage and frequency of the system to fluctuate , the quality of power supply will decline, and in severe cases, it will cause the gas generator to trip and shut down, thus causing serious losses to industrial production. [0003] In the prior art, in order to improve the stability of the gas generator, an automatic control method of an ECU (Electronic Control Unit, electronic control unit) is generally used to realize ...

AI Technical Summary

Problems solved by technology

[0004] After research, the inventor found that when the ECU automatic control method is adopted in the prior art, when the operating point of the generator changes or the transient fault of the power grid system changes, the delay of the motor adjustment is too long, and the gas generator cannot be stabilized in time. speed and ensure the overall stability of the gas generator
