Secondary Equipment Evaluation Based on Multi-Parameter Model for Smart Substation

Abstract

In order to cope with the establishment and practical engineering application of secondary equipment evaluation system for smart substation, the comprehensive evaluation model of secondary equipment which relies on multi-parameter information is introduced. The proposed TOPSIS-based evaluation items, evaluation parameters and evaluation methods are used to evaluate the status of different kinds of secondary equipment. On the basis of various alarm information, telemetry data, remote signal status and other multi-dimensional parameters in process layer, interval layer and station control layer, the status evaluation system of secondary equipment is established to realize monitoring and early warning of normal status and identification and diagnosis of abnormal status.
