摘要

本文开发了一种新的参数校正方法，用于实际配电系统，该方法利用无电压相角信息的重合闸的监控和数据采集（SCADA）数据。为了解决测量值有限、求解容易的问题，推导了参数校正模型，并将其分解为状态估计子问题和参数估计子问题。在实际的、三相的、不平衡的、2135个节点的Dominion Energy配电系统上的测试结果表明，与其他方法相比，该方法提高了参数精度。

A New Distribution Line Parameter Correction Model Using Field Recloser Data

This letter develops a new parameter correction method for realistic distribution systems using available supervisory control and data acquisition (SCADA) data from reclosers without voltage phase angle information. The parameter correction model is derived and decomposed into two subproblems, namely a state estimation subproblem and a parameter estimation subproblem, to address the issue of limited measurements and easy problem-solving. Test results on the realistic, three-phase, unbalanced, 2135-node Dominion Energy distribution system with field measurements highlight the improved parameter accuracy compared to other methods.

期刊介绍： The scope of IEEE Transactions on Power Systems covers the education, analysis, operation, planning, and economics of electric generation, transmission, and distribution systems for general industrial, commercial, public, and domestic consumption, including the interaction with multi-energy carriers. The focus of this transactions is the power system from a systems viewpoint instead of components of the system. It has five (5) key areas within its scope with several technical topics within each area. These areas are: (1) Power Engineering Education, (2) Power System Analysis, Computing, and Economics, (3) Power System Dynamic Performance, (4) Power System Operations, and (5) Power System Planning and Implementation.
