Intelligent Substation Relay Protection Debugging Research And Application

Intelligent substation automation technology is a milestone in the development of a revolution, for all aspects of substation automation system will have a profound impact. Three main features of intelligent substation is "intelligent primary equipment, secondary equipment, network, meet the IEC61850 standard," that intelligent substation information all be digital, networked information delivery, communication model to achieve standardization, a variety of devices and functions to share unified information platform. This makes the intelligent substation in the system reliability, economy, ease of maintenance than conventional substation in a substantial improvement.This article will briefly introduce the historical development of smart grid technology and smart features of the substation, Zhejiang intelligent substation commissioning programmes and processes, introduces intelligent substation relay protection preparatory work and the specific test method for debugging, and so on, and gave some example to analyze several questions and the solution which in the debugging met, had demonstrated through the example analysis the intellectualized debugging the effect which obtained in the practical application.
