With The Grid Outdoor Permanent Magnetic Actuator Recloser On Intelligent Control And Research

The paper researches further the intellectual control of the high-pressure vacuum circuit breaker with bi-stable permanent magnetic actuator and its application in the reactive power compensation of the electric power high pressure, with the practical problem of the control and application technology of intellectual circuit breaker for the basic point, and combining the item of the research of permanent magnetic actuator's microcomputer intellectual controller.The paper takes VR-3S outdoor intellectual circuit breaker of ABB company and the PCD2000 controller of core of VR-3S controlling as prototype, in base of analyzing the structure and principle of permanent magnetic actuator and combining the synchronous shut and opening technical theory and expatiating control algorithm research of synchronous shut and opening. The paper achieves the intellectual control of the outdoor divide-phase permanent magnetic actuator recloser ready, the equipment of using the amelioration realization method can replace expensive inlet one.According to the market's demand, the paper researches the software and hardware realization of synchronous switch. In the design, the paperadopts DSP------TMS320LF2407A made by TI corporation, whichcollects the real time process and controller exterior equipment functions as CPU, and introduces the IGBT intelligent drive design and the design of the keyboard, the liquid-crystal display, the digital signal processor -DSP controller, as well as the installment modular structure. After fully adopts many hardware anti-interference measures, the switch system function perfect, stable is reliable, and realizes through the CAN BUS the correspondence with the inspecting and control room. The software design adopts the module design thought, takes the master routine and the interrupt subroutine as the main structure, completes keyboard processing with the condition analytic method, and realizes liquid crystal display by selecting the OCMJ4X8 Chinese liquid crystal display module.The paper provides the application of synchronous distribution switch in the reactive power compensation of the electric power highpressure, analyses the scarcity of conventional equipments of reactive power compensation, puts forward a kind of realization installment and illuminates its characteristic functions.The control system equipment development had achieved the anticipated effect, the successful develop of the installment provides the good foundation for realizing the synchronous control of the recloser.
