摘要(Abstract)：

为适应同步相量测量技术的应用对配电网产生的影响,提出一种基于二次约束二次估计的配电网状态估计方法。基于配电网节点注入方程以及相量量测的特性,考虑数据采集与监控(supervisorycontrolanddataacquisition,SCADA)系统和同步相量测量单元(phasormeasurement unit,PMU)装置量测数据的融合,通过引入中间变量和二次等式约束,提出直角坐标系下二次形式的混合量测方程,建立了二次约束二次估计模型,并采用合适的优化算法求解,提高了计算精度和计算效率,并具有良好的抗差性。IEEE-123节点算例的分析验证了所提方法的有效性和实用性。

关键词(KeyWords)： 状态估计;相量测量单元;二次约束二次估计;配电网
