华豫电厂机组改接220kV层面驻信地区消纳能力分析

Analysis about Assimilative Capacity of Zhuxin Area for Reconnecting to the 220kV Level about Huayu Power Plant

本文分析了河南驻信地区电网存在的问题,提出了将华豫电厂机组由500kV改接至220kV层面的方案。从潮流、稳定、短路电流等方面,对华豫电厂机组改接至220kV层面后,对主网及驻信地区的影响进行了论证,并分析了华豫机组改接后对电网的利弊。

In this paper,the problems of Zhuxin area network in Henan are analyzed,the scheme of grafting Huayu Power Plant Units from the 500kV to the 220kV level is put forward,which impact to the main network and Zhuxin area network is demonstrated from change of the flow,stability and short circuit current.The pros and cons of grafting to the power grid are analyzed.
