一种准确获取凸极同步发电机原始参数的方法

A method for accurate obtaining the original parameters of salient pole synchronous generator

提出一种获取发电机参数的方法,采用传统发电机参数计算方法得出一组原始参数,对参数进行轨迹灵敏度分析并确定拟修正参数,然后根据典型扰动响应的实测曲线对该套参数进行修正,最终得到一组准确参数。以一台7.5 kW实验模型机为例,采用该方法获取参数,并对多种动态过程进行仿真与试验对比,验证了该方法的正确性和参数的准确性。

This paper presents a new method for determining the synchronous generator parameters. A set of parame- ters are obtained through the calculation of traditional design formulas. Through the trajectory sensitivity analysis of the parameters, the intended correction parameters are determined. Then the set of parameters are fixed based on the tested typical disturbance response curve, and a set of accurate parameters are obtained. The parameters of the 7. 5kW molding machine are obtained by this method. The correctness and the accurateness are confirmed by comparing the simulation results of different dynamic processes with the corresponding experimental.
