Problems solved by technology

[0011] For the 270VDC high-voltage DC power supply mechanism, the above-mentioned control method can realize the voltage regulation function of the steady-state on-load generator load under small transient conditions, but the electromagnetic characteristics of the main generator itself and the configuration of the power supply system determine this Power supply mechanism The power system itself has a large hysteresis, and the transient response speed controlled by the PI adjustment unit in the above control method is relatively slow relative to the load change. At low speed, the generator is demagnetized when the magnetic saturation is high. Slower and longer voltage recovery time. At high speeds, the transient voltage overshoot is larger when the generator magnetic saturation is low; in addition, compared with steady-state on-load power generation, the system voltage regulation The characteristics are weak, causing serious hidden dangers to the safety of the on-board power grid, and it is difficult to meet the high-performance regulation requirements of the on-board power grid for the power system

Abstract

The invention belongs to the field of an electricity generator voltage regulation and control device, and particularly relates to a self adaptive compensator. The self adaptive compensator comprises acompensation signal generating module, a compensation control module and a compensation signal output module, wherein the compensation signal generating module is used for detecting the real-time voltage of the negative end of an exciting winding of an electricity generator, generating a compensation signal according to the real-time voltage and outputting the compensation signal; the compensation control module is used for detecting the real-time current of a load of the electricity generator, generating a control signal according to the real-time current and outputting the control signal; the compensation signal output module receives the control signal; the control signal received by the compensation signal output module has a conduction state and a closed state; and the compensation signal output module can receive the compensation signal in a conduction state, and can output the compensation signal. The invention also provides a high-voltage direct current power generator voltageregulating control system comprising the self adaptive compensator. Through the application, the problems of low-rotating-speed unloading voltage restoration timeout and high-rotating-speed unloadingvoltage overshoot oversize of a high-voltage direct current power supply system can be effectively solved.

Description
