摘要形式仅给出如下。配电自动化包括依赖于实时配电电路状态知识的功能。本文介绍了一个配电电路状态估计器，实现了电力公司配电电路的现场结果。状态估计算法是基于概率径向潮流的方法，将实时测量作为解决方案的约束条件。一个负载建模技术的基础上使用客户计费信息和每日负载配置文件是用来提供所需的负载估计。本文提供了一个评估如何准确地开发的状态估计算法是能够预测电路状态。电路估计作为可用馈线测量的函数的改进也被示出。最后，讨论了实现实际分布状态估计器所遇到的困难。
Summary form only given as follows. Distribution automation encompasses functions that rely on knowledge of the state of the distribution circuit in real-time. This paper presents field results for a distribution circuit state estimator that was implemented on an electric utility distribution circuit. The state estimation algorithm is based on a probabilistic radial power flow approach that incorporates real-time measurements as solution constraints. A load modeling technique based on using customer billing information and daily load profiles is used to provide needed load estimates. This paper provides an assessment of how accurately the developed state estimation algorithm is able to predict circuit states. The improvement in circuit estimates as a function of available feeder measurements is illustrated as well. Finally, difficulties encountered with implementing an actual distribution state estimator are discussed.
