摘　　要：对西部地区高压配网的现状网和规划方案中的高压配电网进行了可靠性评估。具体分析了西部地区电网的网络拓扑结构。针对高压线路特点,运用直流潮流法判断线路的过负荷状态。根据《供电系统用户供电可靠性评价规程》的要求,得出了基本的可靠性评价指标。结果的合理性证明了在高压配网可靠性评估中应用直流潮流法的可行性。This application is in allusion to the layout of the high-voltage distribution network of West power grid. Take its configuration into account. Put the method relating to DC-flow into practice to estimate high-voltage feeders overload or not. Educe the indexes ofreliability evaluation that referred by reliability evaluation rules. The validity and practicability of the method was examined by this application.
