With the development of the power industry, people's demand for electricity is growing, there is a contradiction between the current power resources and user demand for electricity, the main reason is that the substation operation there are some problems, causing power resources hard work. Relay system has excellent features, it is effective and safe protection measures, it can not only reduce the time the error was found, but also narrow the scope of failure, to ensure the normal operation of the other components. The article first analyzes the role, composition, requirements of relay protection, and then analyzes the fault analysis of power system protection and treatment measures; the final analyzes the question of the relay protection substation operation. Substation operation on problems and shortcomings of relay protection were discussed, and put forward some countermeasures on how to improve relay protection. Relay protection device may shorten the time of cutting equipment, reduce the probability of non-faulty devices removed, and alert information via automation. Because of this strong utilization, deterministic, high reliability, it has become the most effective measures of relay protection. Modern technology can not do without electricity, people's social life is inseparable from power, and so strong relay protection system has become increasingly a major problem.
