Design and Analysis For Reliability of Control Function in Substation Automation

Along with the development and application of substation automation system, the influence of reliability of its control function on the secure and stable operation of power network becomes more and more important. Here, taking a substation supervisory and control system for example, the model that may cause incorrect operation is established, several measures to ensure the correctness of control operation are presented, and algorithm to ensure the correctness of control operation is designed. The consistency, uniqueness and realtime performance of the model are analyzed. The practical application results prove that the presented algorithm is effective.
