摘要
建立规划变电站直流偏磁评估模型,借助潮流计算中的电网数据获取交流电网的直流网络信息。根据该模型开发直流偏磁评估系统,并以规划中的广东惠州220 kV沙逵变电站直流偏磁评估为算例说明该系统的具体应用方法。将该系统应用于广东电网,仿真系统计算值与监测系统测量值的对比结果表明,该评估方法有效。
DC bias assessment model of planned substation is established to obtain data of DC networks in AC power grid by means of grid data in flow calculation. On the basis of this model, DC bias assessment system is developed and the applica- tion method is expounded by the example of DC bias assessment of planned 220 kV Shakui substation in Huizhou, Guangdong Province. The method is used in Guangdong power grid and the comparison between calculated value of simulation system and measured value of monitoring system shows that the assessment method is effective.
