摘要
针对廊坊胜芳地区电网无功功率严重缺乏的现状,在介绍了主网变电站和配电网中采用的无功补偿方法和手段的基础上,分析了该地区电网无功运行中存在的问题,指出了用户变电站和专线用户无功考核缺乏力度、无功补偿电容器损坏后不能及时修复等导致无功缺乏的原因。提出了加装有源滤波器、使用VQC管理变电站和加强无功管理制度建设等措施和建议。
Based on the introduction of reactive power compensation measures taken in Shenfang distribution system of Langfang grid, this paper analyzes the weaknesses of the system operation and the causes of reactive power scarcity such as user＇s substation and private line substation lack of investigation, capacitor banks damage can＇t be repaired. Finally the suggestions to resolve the compensation problems are proposed.
