摘要
本文对海上石油平台供电网励磁涌流产生的原理进行了分析研究,提出了具备先进控制算法的涌流抑制器解决方案。该抑制器通过变压器断电时电压的分闸相位角获知磁路剩磁的极性,从而可选择在相近的相位角进行下一次合闸,使励磁涌流得到抑制,运行以来取得良好效果。
By researching the principle of the exciting surge,this paper offers the exciting surge controller solution for offshore platforms power grid.The controller obtains the remanence polarity from the voltage phase when transformer is openned,so that it can close at this phase in next close operation,and the exciting surge can be controlled.
