Influence of the UHVDC project from Jiuquan to Hunan on stability control strategies in Hunan power grid
摘要
Abstract
To research the influence of UHVDC project from Jiuquan to Hunan on the stability control strategies in Hunan power grid,the current situation of stability control strategies is firstly presented.Then,the stability control strategies of UHVDC bipolar block fault and serious fault of 500 kV AC lines from Xiangtan converter station are analyzed.The receiving-end stability control strategy of UHVDC may affect the current stability control strategy of tie-lines between Hunan and Hubei depending on the choosing of load shedding stations.Because of the load flow change coming with UHVDC,the current stability control strategy of internal section in the middle of Hunan will become invalid.The coordination measures of load shedding and DC emergency control are proposed to deal with serious fault of AC lines in receiving-end power grid.The research results offer references for the configuration of the UHVDC's receiving-end stability control strategy and the adjustment of current strategies in Hunan power grid.关键词
