自备电厂孤网运行稳定性方案

Operation stability scheme of isolated network in self-provided power plant

通过实例介绍了兖州煤业榆林能化有限公司自备电厂孤网运行18小时,带负荷一次并网成功。实践证明,兖州煤业榆林能化有限公司自备电厂就现有设备而言,在可预知的110k V两回进线故障时,自备电厂孤网稳定运行是切实可行的。本文还对外电网故障状态下,自备电厂实现孤网运行进行了探讨研究。

Through an example, this paper introduces the successful connetion of Yulin energy chemical co., itd in Yanzhou coal industry with load after 18 hours of operation. Practice has proved that Yanzhou coal Yulin energy co., itd owned power plant in terms of existing equipment,in the predictable 110 Kv two back into the line failure, owned power plant isolated network operation is feasible. This paper also discusses how to realize isolated power network operation in self-provided power plant under external power grid fault condition.
