| With the increase of electricity consumption, the production life put forward higher request to the development of electric power industry, security personnel and equipment of transformer substation becomes especially important.It’s because improving the safety of the substation equipment is crucial to ensure the supply of high quality power. That’s why the substation anti misoperation locking technology arises, and it is developing with the help of electric power technology and computer technology.Preventing electrical misoperation has become an important part ofelectric power automation technology, and it provides a powerful support for the safe operation of the power system.Remote control operation of the substation must be carried out by the monitoring system, the security prevention system to be combined and protected to complete the normal operation of the task. There are many defects in the traditional security prevention system, such as wave communication is not stable, resources, etc., already cannot satisfy the requirement of power system now, to realize the operation ticket and anti misoperation locking function and support including five professional anti computer hardware manufacturers key communication interface, with security prevention system, electric equipment of anti maloperation. Its appearance will be, the traditional microcomputer security prevention system and integrated automation system for the integration of resources, realize the sharing of data information across the platform.Against disadvantages of the traditional security prevention system, this pape r is mainly about the technical characteristics, the overall framework of the back end systems are studied, such as optimized solutions for five prevention system was put forward, the main work accomplished in this paper are as follows:1.1 analysis the practical problems for security prevention system, and put forward the feasible solution;2. I analysis the overall structure and modules for backend system,and put forward the feasible solution;3. To integration of five prevention system is embedded in the background system and the system transformation upgrade to become the integration of online security prevention system.It’s to improve security prevention system stability, reduce the cost of construction and maintenance.4. The substation control layer security prevention scheduling system and ter minal security prevention system to realize the communication, the dispatching te rminal and substation control layer is more closely linked, can be better on the substation control layer monitoring protection. This will not only adapt to the act ual situation of the company, and can be very good to satisfycustomer needs.5. Finally, the integration of security prevention online monitoring system of systems were tested, the results achieve the desired design requirements. |
