| In order to ensure the power system security, reliable and economic operation of the target.,FACTS (including system application technology and its controller technology) use the modernhigh-power electronic technology to reform the traditional AC power system. It is considered amajor technical reform measures can be implemented in the beginning of twenty-first Century.In general, the switching operation with the operation ticket after the power is off,There existproblems and deficiencies that it has a low degree of automation and intelligent,the result ofhuman error caused by security hidden trouble and influences the production efficiency。The keyis that distribution network is a dynamic system. If the operation with load must be producingtransient impact current and threat to network. This impact is sufficient to make the whole powersystem instability and collapse. Visible, research of the intelligent switching device hasimportant practical significance.The bus-bar switching matching device belongs to the power supply applications of theelectric power system. The view of designing the automation device is for the safety operation ofswitching process in electric power network. it is designed for the safe operation of the powerswitching process automation device. The device can solve that the traditional operatingproblems. Its application can improve the production efficiency, and operation process on theelectric power grid. It also improves the degree of automation of production.This paper focuses on control strategy of the device. By comparing today’s domestic andforeign advanced sliding mode variable structure control algorithm. It introduced switchingmatching device controller by appropriate selection and improvement. Simulation and analysisfor the power system and the whole switch matching device by Using MATLAB2010a Simulinksimulation platform. On this basis, perfect the hardware circuit, to realize the algorithmapplication in bus-bar switching matching system. Verify the correctness and feasibility oftopology and control strategy. |
