| 摘 要： | 介绍了一种基于发电机定子故障暂态数据的主保护测试系统.该系统利用多回路理论建立发电机内部故障仿真模型,计算出内部故障的暂态数据,同时把故障数据转换成COMTRADE格式储存.对保护装置进行实时测试时,利用测试仪的故障波形回放功能,将存储数据转换成模拟量送入保护装置,从而实现对保护装置的测试.仿真试验表明,该测试系统具有精度高、体积小、结构简单等特点,能对发电机主保护进行各种故障条件下的详尽评测.

| Abstract: | This paper presents a main generator protection testing system based on transient simulation program of generator stator winding internal faults.This system builds up a model of generator internal faults based on multi-loop theory.And then it gets transient waveform data through off-line calculation,which is transformed to standard COMTRADE.In the real-time test,test device is used to recur the transient waveform in terms of COMTRADE data.The faults waveform recurred is sent to protection device and complete the test of the protection device.It is validated that the whole main generator protection testing system,which is high in accuracy,small in size,and simple in structure,can give detailed evaluation to main generator protection in various fault conditions. |
