Abstract

Abstract:

This paper discusses the digital simulation methods with parallel computing of large-scale AC/DC power systems. Firstly, we introduce four power system simulators with parallel computing capability, and analyze their characteristics and applicability. Secondly, we compare three equivalent methods of power system including: the equivalent method based on frequency response, the Ward equivalent method and the dynamic equivalent method based on physical equivalent； and analyze their advantages and disadvantages. Then, we study the parallel computing method of large-scale AC/DC power system based on PSCAD/EMTDC simulator in detail, from three aspects of model transformation and correspondence, element layout and connection, subsystem division. Meanwhile, we comprehensively analyze the parallel computing simulation method of large-scale AC/DC power system based on RT-LAB, as well as the system's initialization in detail.

Key words: parallel computing, digital simulation, large-scale AC/DC power system, PSCAD/EMTDC, RT-LAB
