Abstract

The invention discloses an electric-information-based equipment performance evaluation system and an electric-information-based equipment performance evaluation method. The measured electric information of the conventional supervisory control and data acquisition (SCADA) system is fully mined, and the performance of elements can be effectively reflected by performance indexes formed by combining electric quantities. The performance of the elements of a power grid is dynamically evaluated in real time by comprehensively using the theory of random processes. An adopted client/server (C/S) architecture comprises a basic data layer, an element performance evaluation platform and an analysis application layer, wherein the basic data layer provides a basic data platform for realizing the functions of the system; the element performance evaluation platform realizes the running performance evaluation of a substation and a transmission line on the basis of generalized power grid topology division; and the analysis application layer timely discovers elements with degraded performance to provide a reference for the electric equipment overhauling of operational staff according to element performance evaluation results on the basis of the element performance evaluation platform.

Description

technical field [0001] The invention relates to an electrical information-based equipment performance evaluation system and method, which realizes real-time procedural evaluation of equipment operating performance on the basis of mining the minimum characteristics of power grid equipment performance indicators and using peripheral electrical measurement information. Background technique [0002] The safe operation of transmission network components is the basis for building a strong power grid, and the safety management of components runs through their entire life cycle. In response to the problem of how to inspect and evaluate the health status of cycle process components, the State Grid Corporation issued the "Evaluation Standards for Power Transmission and Transformation Equipment" in early 2006. [0003] According to the "Implementation Opinions of the State Grid Corporation on the Evaluation of Power Transmission and Transformation Equipment", in order to strengthen the...
