【摘要】 电磁环网是在电网发展过程中产生的一种特殊的网架结构。电磁环网的存在给电网的发展带来许多不确定因素,国内外与电磁环网相关的大停电事故屡见不鲜。解开电磁环网运行将是必然的选择。本文分析了电磁环网对电网经济、可靠运行带来的影响,概述了电磁环网解环运行的评判原则。在上述原则指导下制定了内蒙古大乌海地区500kV-220kV电网环网解环的方案及相应的运行方式,利用电力系统潮流计算软件BPA对解环后的电网进行计算,分析的结果表明所制定方案是可行的。最后根据计算的结果对内蒙古大乌海地区500kV-220kV电网环网解环运行提出了相应的建议。本文对于中国其他地区电磁环网解环操作具有一定的参考价值。更多还原

【Abstract】 The electromagnetically coupled power loop is a particular form of network configuration. The operation of electromagnetic loop network results in many uncertain problems and accidents having something to do with electromagnetic loop which occur commonly in either foreign or domestic countries. So it is inevitable to breakout electromagnetic loop network.Under the guidance of the above-mentioned principles, the solution program and corresponding operating modes of 500kV-220kV electromagnetic loop untying of Da Wuhai region in Inner Mongolia grid are drafted out. The power grid is calculated after Da Wuhai electromagnetic loop is broken out using power flow calculation software BPA, the analysis results show that the solution program is feasible. Finally, according to the calculation results, corresponding recommendations are provided for the running of Inner Mongolia region Wuhai 500kV-220kV electromagnetic loop untying. It is valuable for electromagnetic loop solution in other parts of China.更多还原
