摘要
针对攀钢电厂12#机组在运行中出现无功功率输出频繁反向波动的问题进行了研究和分析,从励磁调节系统内外查找原因,确认是碳刷接触电压过高所致,采取措施解决了问题。
The problem of frequent reverse fluctuation in the reactive power output of the No.12 generator unit of Panzhihua Steel were studied and analyzed. Searching the causes from both inside and outside of the excitation regulating system, it was confirmed that exces-sive carbon brush contact voltage had caused the problem and effective measures were taken to solve the problem.
