摘要(Abstract):
早期600 MW发电机励磁调节器使用进口设备,长期运行后UN5000型发电机励磁调节器出现的一些问题影响了机组的安全稳定运行,为此对励磁调节器进行了改造,针对改造后出现功率柜均流问题,提出加装脉冲调节柜的措施,有效解决了励磁均流问题。
In the early time, excitation regulators imported from abroad were used for 600 MW generators. After long operation, problems occurred in UN5000 excitation regulators of generators affect operation safety and stability of units. Therefore, the excitation regulators are transformed. To handle current sharing of power cabinet that occurs after the retrofit, the paper suggests equipping pulse conditioning board and excitation current sharing is effectively finished.
