The Application Study Of Misoperation Locking Device In Substation

With the development of the computer and network communications technology, computerized relay protection and automation system had applied in power system, which made the management of substation realized non-attended. Full automation and non-attended substation have become an inevitable trend of the dispatching automation of electrical network and autoimmunization of power system now.The security threats of misoperation incidents on the network, equipment, physical and the resulting loss have become an increasingly serious problem. Therefore, adopting misoperation locking device in substation has become a kind of important and effective technical measure for preventing the misoperation.Based on the in-depth studying on the basic principles, locking design, features and the structural model of computertized anti-misoperation and lockout system, considering the actual operation of tao yuan 220 kV attended substation, from the system components and connect major types of data files of the establishment, as well as system initialization, and so on, the FY2000 type computeritized anti-mislock system installation and operation of the entire process have been introduced, which provides a workable reference to specific examples, convenienting for operation personnel to know well and master technical features and methods of functions to achieve of anti-misoperation and lockout system. According to the actual operation of equipment of tao yuan 220 kV attended substation and improvement.
