摘要
“十一五”期间,随着广西南部电网电力需求大幅度增长和钦州、防城港电厂共4台600 MW机组投产,现有220 kV网架结构薄弱不能满足其供电和电源电力送出要求,迫切需要提升、加强网架结构。通过分析广西南部电网的现状以及存在的问题,针对目前电力需求增加的情况就如何保证西电东送的安全稳定,提出了广西南部电网500 kV变电所布点和网架方案。通过对运行方式和安全稳定性的分析,验证了此方案的可行性。
During the“11th Five yeas”, following the significant rise of power demand in south Guangxi and the operation of 4 ×600 MW generators in Qin-zhou and Fang-cheng-gang thermal power plants, the configuration of existing related 220 kV power network has to be urgently upgraded and strengthened to saticfactorily meet the requirements for the power delivery. For this purpose, the paper suggests a plan for network construction and locations of 500 kV Substations in South Guangxi. The plan was validated feasible by analysis about mode, security and stability of operation.
