Research On The Testing Method Of The Intelligent Substation Protection Of The BENXI 220kV GAOGUAN Substation

Ntelligent substation is a Digital device, which uses advanced, reliable, integrated and environmental protection, with total station information digitization, communication platform networking, information sharing standardization as the basic requirements, automatic completion of information acquisition, measurement, control, protection, measurement and detection, and other basic functions, with support for real-time automatic control, intelligent regulation, online analysis and collaborative interaction and other advanced functions of the substation.Benxi 220 kV senior officials in Benxi area is the first 220 kV Smart Substation, compared with the conventional computer protection, intelligent substation equipment from a fundamental change, because this is the first 220 kV Benxi digital substation, and there is no standardized operating procedures and testing methods. Through the study of other digital substation and the actual situation of 220 kV senior officials to develop a set of standard operating procedures and debugging methods, and through the actual test data to verify its feasibility, and finally to think about the improvement of the commissioning party. And improve the practical ability of the digital substation.At the end of this paper, some points of attention in the process of the protection of intelligent substation are proposed, as well as the problems left over by the debugging, and provide some experience and reference for the Digital substation commissioning in the future.
