Abstract

The state assessment is an important means to evaluate the condition of substation equipment. In this paper, a fuzzy comprehensive evaluationbased method is proposed to evaluate the substation equipment. The proposed method can provide an comprehensive evaluation of substation equipment and establish the operating state level for the management of substations. The conventional method usually utilizes the single item scoring method. While the proposed method can evaluate the states of substations from multiple aspects more effectively and more accurate. A simulation example is demonstrated to introduce the procedure of state evaluation. As an instance of application, the state management and control level of substation equipment in Beijing power grid has been greatly improved, and the equipment failure rate have been declining in recent years.
