Abstract


Power system dynamic simulation credibility directly affect the safe and economic operation of power grid, and how to improve the power system simulation credibility is the urgent need to solve a problem. And generator is the electric power system of power plant, the power system transient and steady-state operation plays a vital role, the generator simulation credibility problem has its practical significance. The paper using trajectory sensitivity method for the synchronous generator parameters sensitivity analysis, it is concluded that the turbulence intensity, parameter recognizable and parameter sensitivity that the relationship between the three. Through the genetic algorithm to the synchronous generator parameter identification, looking for the parameters of the great influence of error, the correction, the use of group developed simulation credibility evaluation system, the parameter correction before and after the current waveform analysis and comparison of results show through the identification of the parameters in a certain extent, improve the synchronous generator simulation credibility.
