摘要

考虑了两种基于扰动的同步发电机转子加速度能量分析方法。采用时域等面积判据对系统进行稳定性分析。采用所提出的铁心饱和电流互感器二次电流校正方法，保证了电流的测量。利用Matlab Simulink软件在4总线模型上测试了该方法的性能。结果表明，饱和电流互感器的误差值不超过3%。

Acceleration Energy Analysis of Synchronous Generator Rotor During a Disturbance Taking into Account Current Transformer Saturation

Two methods of disturbance-based energy analysis of synchronous generator rotor acceleration were considered. It was done for the purpose of stability analysis using the equal area criterion in the time domain. The current measurement was ensured by using the suggested method of correcting the secondary current of current transformer with saturated core. The methods performance was tested on the 4-bus model using the Matlab Simulink software. The results have shown that error values did not exceed 3% for saturated current transformers.
