摘　　要：长治—南阳—荆门特高压交流试验示范工程是连接华北和华中两大电网的唯一通道,由于其输送功率大,发生在任何地方的发电和负荷有功扰动都对联络线输送功率产生影响,引起特高压联络线功率在计划值的基础上产生大范围的波动,从而引起区域控制偏差的大幅波动,对山西联络线潮流控制产生较大的影响。对特高压检修及特高压投运时的山西电网区域控制偏差的波动情况进行了详细分析,对调度运行提出了建议。The Changzhi-Nanyang-Jinmen ultra-high voltage AC demonstration project is the only line connecting North China and Central China grid.Due to its large transmission power,active power perturbation of generation and load which occur in any place can affect transmission capacity of tie-line,and the line power,based on scheduled value,will produce large-scale wave,which causes large wave on area control error and has a strong influence on tie-line power flow in Shanxi.This paper analyzes the wave complexion grounding on ultra-high voltage operating and maintenance,and puts forward a proposal for dispatch and operation department.
