【摘要】 为了减小电容投切所产生的谐波、涌流等暂态过程的危害,提出了一种基于DSP的相控开关控制器,自适应的控制断路器在电压电流的零点投切电容组。控制器采用新型DSP产品dsPIC30F6014芯片为核心。该芯片计算能力强、外围器件丰富,使系统设计得以简化,可靠性提高。仿真测试表明,该系统达到设计要求,工作稳定可靠。更多还原

【Abstract】 In order to reduce the harm of transient course appeared in capacitor banks switching,such as harmonic and inrush current, here brings up a phase_controlled switching controller based on DSP.It makes the vacuum circuit-breaker act at the zero point of voltage or current adaptively.The kernel of this controller is a new DSP chip dsPIC30F6014,which has powerful calculation ability and various peripheries.Because of those characteristics,the design comes to simpler and more reliable.Practice in simulator show:the system works reliably,functions satisfied the design request.更多还原
