延安南部电网结构变化应对措施研究

Research on Countermeasures for Variations of Southern Yanan Power Grid Configuration

2007年年底黄陵矿区煤矸石热电厂Ⅱ期2×50MW机组并入延安电网,届时,延安地区南部电网的网架结构相应发生较大变化。为使延安南部电网安全、稳定、经济运行,对330 kV黄陵变两台主变不能送出时,南部电网能够采取的运行方案及措施进行分析研究,对各种运行方式中可能出现的问题提出解决措施。

By the end of 2007, Huangling Gining Area Gangue Heat ＆ Power Plant stage Ⅱ 2×50 MW generators are connected to Yanan Power Grid, then, southern Yanan Power Grid configuration has great changes correspondingly. To ensure safety, stability and economy operation of southern Yanan Power Grid, the operation schemes and measures are analyzed and studied, which are adopted in two main transformers stop working in 330 kV Huangling Substation, and the solutions for the problems occurred in different operation modes are put forward.
