摘要
220kV姬村变承担着宿州城市范围城市居民、工厂、煤矿及一部分农村供电任务,是宿州电网重要的220kV枢纽变电站。长期以来,姬村变两台主变中压侧一直并列运行。但是,随着近几年电网规模的增大,此方式存在较多的安全隐患,需要重新考虑两台主变分列的运行方式。本文从姬村变主变的潮流平衡、小网内发电机与负荷的平衡性、电网稳定分析等角度,分析比较姬村两台主变并列及分列运行两种方式优缺点,论证了两台主变分列运行的可行性。
The 220kV Jieun transformer substation, which is the center of Suzhou power grid,supplies the power for inhabitants in Suzhou city, the factories and coal mines around it. It also supplies the power for reighboring eountry. For certain reason, the medial sides of the two transformers in Jicun are paratactic for a long time. But with the development of Suzhou power grid in this years, the old running mode exposures too many hidden troubles. So a separated running mode for transformers in Jicun must he thought about. To find the merits and shortcomings of them, the treatise compares the two running modes on the distributing of power flow, the balance between the loads and generators, the stability analysis on Suzhou power grid, etc, and demonstrates that the separated running mode is doable.
