doi:10.3969/j.issn.1000-7229.2015.11.016

Abstract

Abstract:

UHVAC transmission can achieve the optimal allocation of energy and resources in a wide range， which can provide strong support for the coordinated and sustainable development of social economy. As an important guarantee for its safe operation， circuit breaker has been widely and deeply studied all the time. The complex electrical characteristics of UHV transmission system such as bundled conductor parameters， over voltage and electromagnetic environment greatly have great impact on the reliable action of circuit breaker， and put forward higher requirements on its motion characteristics and sensitivity. Based on the analysis of domestic UHV projects put into operation， the new characteristics of circuit breaker protection caused by the above factors were studied. The configuration based on PCS-921G device of the circuit breaker protection and the corresponding settings concerning failure protection， three-phase inconsistent protection， over-current protection， and automatic reclosing lock were presented and verified， which could provide valuable design basis for the subsequent circuit breaker relay protection in UHVAC projects.

Key words: UHV, circuit breaker, relay protection, configuration and setting
