　　Abstract: In this paper, the importance of the anti-misoperation locking of electrical equipments and the requirements of the modern power network on the application of wide-area anti-misoperation locking are analyzed, and then a wide-area mal-operation prevention system in power network based on the GPRS is proposed, and finally the general design idea of the system is introduced. Also, the designs of the software and hardware (important components of the system) of field controller as well as anti-jamming performance are discussed in details, and simultaneously the designing method of the mal-operation prevention monitoring center (another important component) is introduced. The wide-area mal-operation is judged by using GPRS wireless Internet to interact field switch state and management monitoring center in real time. Therefore, it features simple logic judgment, easy-to-implement, and low cost, etc.
