doi:10.3969/j.issn.1000－7229.2017.04.012

Abstract

Abstract: ABSTRACT： This paper firstly analyzes the error mechanism of electromechanical and electromagnetic hybrid simulation caused by the multi-port coupling, and deduces the coupling relationship between ports with and without the change of DC current considered. Then, to reduce the simulation error caused by coupled multi-port modeling and ensure the simulation accuracy within the limitation of modeling ability of RTDS as much as possible, this paper studies the multi-port decoupling index for the electromagnetic side in electromechanical and electromagnetic transient hybrid simulation. According to port decoupling with different coupling strengths, this paper adopts feature selected validation （FSV） method to analyze the quantitative relationship between port coupling strength and simulation precision, and obtains the decoupling index of ports which fulfills the ‘good’ standard validated by FSV. Finally, the validity of the proposed decoupling index is validated through the real time hybrid simulation platform of complex 500 kV and above AC/DC power network in a certain area.

Key words: electromechanical and electromagnetic, error mechanism, multi-port coupling, decoupling
