The optimal optimization design on parameters of bi-stable permanent magnetic actuator with particle swarm algorithm is given in this paper; and an intelligent controller is developed. The hardware design takes DSP TMS320F2812 as the master controller, including the power supply, microprocessor system, capacitor voltage detecting circuit, switch winding control circuit, input/output unit, over/under voltage monitoring, protection units, GPRS communication unit and so on. Remote distant monitoring can be realized by the use of optical fiber or wireless. Zero sequence current protection can distinguish inner and outer mistakes. Distant control operation is designed with measures to avoid mistakes. The technical measures are put forward to guarantee the reliable operation of IGBT parallel circuit and avoid the influences on manual switching operation. It is proved that the designed circuit is feasible by comparing actual measured data with results from simulation with multisim software. Finally, site tests show that the intelligent controller is reliable and smart, and show perfect performance on controlling switch intelligently.
