摘要

Abstract

In this paper

the calculation method and transient characteristics of asymmetric faults in the DC side of a true bipolar system are studied. First

two typical MMC fault equivalent methods are analyzed

and comparison shows that active RLC equivalent branches are more suitable for fault analyses of a true bipolar system. Second

considering the influence of mutual impedance between the poles in DC side

a DC fault current calculation method for a true bipolar systems is proposed. Finally

the characteristics of transient electrical quantities including fault current and DC voltage in the process of DC faults in true bipolar systems are analyzed and summarized to provide references for the design of DC line insulation and relay protection schemes.
