Along with the development of substation automation system, the influence of correctness of its control functions on the secure and stable operation of power network becomes more and more important. Here, taking a substation supervisory system for example, the error model which may cause maloperation is established, several measures to ensure the correctness of the control operation are put forward and an algorithm to ensure the correctness of control operation is designed. The formal analysis on the consistency, uniqueness and real-time performance is conducted. The practical application results prove that the presented algorithm is effective.
