| 摘 要： | 加权最小二乘法是当前配电网状态估计的常用算法,但它对于粗差的处理能力不足,量测量中的粗差会使估计结果严重偏离真值.介绍了一种抗差原理,利用权因子把一般性的M估计转换为加权最小二乘法,并将之应用于配电网的状态估计.通过测试,证明该方法可以有效减小或消除量测量里面的粗差影响,对于配电网状态估计技术有较强的实用价值.

| Abstract: | WLS(weighted least square) is a popular state estimation algorithm used in distribution network. But it's not efficient in handling gross error which will result in a great deviation from the true value. The Robust Estimation is introduced,which transforms the universal M-estimation to WLS. Then the method is applied to the state estimation in distribution network. This method is efficient in decreasing or diminishing the gross error influence and is applicable to estimation technologies in distribution network. |
