| 摘 要： | 基于Volterra在线参数辨识方法，通过数字仿真、模型参数辨识、模型替换和外特性交叉对比等步骤，分析了恒阻抗加感应电动机模型（ZM模型）与ZIP模型、ZIP加电动机模型（ZIPM）之间的等效性及ZM模型的适用范围。仿真结果表明，当ZIPM负荷中ZIP部分的恒阻抗负荷占比大于70%时，辨识出的ZM模型与原始模型在外特性上的相似程度可以满足机电暂态仿真的要求。

| Abstract: | Based on Volterra online parameter identification method, by means of digital simulation, dominant parameters identification, model substitution, as well as external response characteristic comparison, the equivalency and adaptability of using ZM model to represent ZIP model or ZIPM model are investigated.Simulation results show that, when the proportion of constant impedance load of ZIP portion in ZIPM model is greater than 70%, the external response characteristics of equivalent ZM model are similar to the ZIPM model, and can satisfy the requirements of electromechanical transient simulation. |
