摘要

提出了一种电力系统状态估计中变电站的详细表示方法。将断路器的有功潮流和无功潮流作为状态变量，对传统的加权最小二乘状态估计进行了扩展。基于简化模型确定了电力系统的可观测性和状态估计。该方法以一个12总线系统为例进行了说明。

Detailed representation of substations in power system state estimation

This paper presents a method for detailed representation of substations in power system state estimation. The conventional weighted least squares state estimator is extended by incorporating the active and reactive power flows of circuit breakers as state variables. Power system observability and state estimates are determined based on a reduced model. The method is illustrated with a 12 bus system.
