Analysis of the operating characteristics of the integrated power system under the action of pulse load

Aiming at the stability problem of integrated power system under the action of pulse load, a stand-alone simulation model of single-shaft gas turbine, twelve-phase rectified synchronous generator and pulsed load is established, the dynamic process of suddenly adding pulse load to generator sets without thinking about energy storage and pulse power conversion device is analyzed in detail, and the main influencing factors of electrical index changes such as transient voltage regulation rate and transient speed regulation rate of generator sets under pulse load are studied. Simulation tests on the operating characteristics of generator sets under continuous pulse load conditions are also carried out. The results show that the dynamic performance of the generator set is closely related to the operating mode of the pulse load, and the parameter changes such as the rising time, peak power, and time interval of continues loading will have different effects on the dynamic performance of the unit during the loading process, which provides a basis for the coordinated optimization control of the gas turbine speed regulation system and the twelve-phase rectifier synchronous generator excitation system in the next step.
