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.
