摘要
分析广州蓄能水电厂静止变频器控制逻辑测量发电机转子初始位置的方法,指出其缺陷在于SFC测量转子初始位置开始时间的确定依赖于外部回路。说明这一缺陷可以通过优化静止变频器控制逻辑来实现对测量转子初始位置来清除。实际运行数据证明了新方法是行之有效的,可为同类型静止变频器控制逻辑的改进提供参考。
This paper analyzes the method used by Guangzhou Pumped Storage Power Station to detect the rotor initial position through the control logic of the static frequency convertor （SCF）, pointing out that the bug in the method is to depend on the exterior circuit. Furthermore, it is shown that the bug can be cleared away by optimizing the static frequency convertor logic for detecting the rotor initial position. The effectivity of the new method is validated with the measurement data of operation, and thus this method can be taken as reference for control logic inprovement of the similar SCFs.
