摘　　要：从无功补偿、风电出力、线路充电功率等方面分析了乌兰察布地区电网的无功潮流分布特性,尤其针对风电典型出力日,分析地区有功与无功潮流的流向,及时查找不足并分析电网的潮流分布是否合理。当系统无功潮流与有功潮流方向不一致,或者无功潮流数值比较大时,地区电网损耗会加大,进而造成地区电网出现低电压或者高电压问题,甚至引起由于低电压造成的电网解列或者崩溃。对此,提出尽快修复系统变电站的故障电容器,并加强对风电场电容器的投退管理等建议,以提高地区电网的运行稳定性。This thesis focuses on the reactive power flow cistribution characteristics in Wulanchabu power grid from aspects of reactive power compensation, wind power and line charge power power, especially for the wind power output, the analysis of active and reactive power flow, to find the deficiency and analyze the power flow distribution reasonable or not. When the direction of reactive power flow and active power flow are different, or reactive power tidal current is larger, the loss of regional power grid will increase, causing the regional power grid appears low voltage or high voltage, or even appears power system splitting or collapse due to low voltage. Therefore, the author put forward the suggestions to repair system for substation fault capacitor, and to strengthen the management and switching capacitor to the wind farm the improve the operation stability of the regional power grid.
