Study and Application of 220kV Substation Relay Protection Training System

摘要

With the large-scale application of power electronics technology and computer technology in grid operation, automation level of the grid production and operation maintenance in China is increasingly higher, which also proposes higher requirements on the professional theory and skills of frontline staff in grid operation. Relay protection and automation devices are an important part for the safe and stable operation of power grid and also key tools and methods to protect the safety of electrical equipment. Therefore, how to quickly improve the technological level of front-line staff in grid operation and maintenance so that they can meet the needs of automotive and informative development of power grid has become a key obstacle for the safe and stable operation of power grid. At present, theoretical and technical trainingsfor front-line staff of power system operation and maintenance are mainly carried out in the form of regular experts and electricity universities training courses organized by the enterprises, and teaching by certain elder staff at the scene. However, there are certain limitations in the above two training methods in that they cannot meet at the same time the theoretical and practical and technical development needs and that the training results are not always satisfying. Therefore, in order to adapt to the rapid development of power system in China, it is urgent to establish a sound and systematic power system relay protection and automation operation and maintenance personnel training system, which should include basic theory training, practice operation and other cutting-edge power technology overview, so as to make it possible for the frontline staff to learn theoretical knowledge and at the same time have a grasp of the power system development trend and new technologies probably to come. It should ensure that the frontline staff understand and learn new methods for relay protection and automatic detection.
