| 摘 要： | 提出了电力系统负荷模型中统一模拟配电网网络、无功补偿和感应电动机的模型，该模型可以简化电力系统仿真中配电网络的模拟，提高了配电网络中感应电动机模型的精度；同时提出了一种确定配电网络无功补偿容量的简便算法。所提出的模型和算法已在PSD电力系统分析软件工具(PSD Power Tools)中的中国版BPA暂态稳定程序和电力系统全过程动态仿真程序中实现，该程序可根据配电网络的综合阻抗和指定的电动机机端电压与系统母线电压的比值系数，自动求得无功补偿量和无功补偿电抗值。模型和算法可以提高电力系统仿真中计及配电网络和无功补偿的感应电动机模型的精度。并得到了验证。

| Abstract: | This paper presents a unified model to simulate distribution network, reactive compensation and induction motor for the load model in the power system simulation. The distribution network and reactive compensation can be included in the induction motor model of load by the unified model, so it can be simplified in the power system simulation, and the simulation accuracy can be improved. A simple and convenient algorithm for calculating reactive compensation capacity in distribution network was presented in this paper. The proposed model and algorithm were implemented in the PSD Power Tools, a power system analysis package, including China version BPA Transient Stability Program and the Power System Full Dynamic Simulation Program, and validated. |
