摘　　要：针对多组带微机保护器的并联电容器无功补偿系统的不足,研制了将无功补偿与微机保护功能集为一体的测控装置,通过RS485总线组成主从式无功补偿与电容器保护系统。重点介绍了以dsPIC33EP单片机为核心的测控装置硬件设计。软件设计中着重讨论了主要参数测量的编程算法、主从式控制的主机产生策略、通信协议和电容器保护配置与判据的主要编程算法。As for the shortcomings of reactive power compensation system of multiple shunt capacitor banks with computer protection devices, a measurement-control device integrating reactive power compensation and computer protection as a whole is developed and a master-slave control system for reactive compensation and capacitor protection is formed through RS485 bus. Hardware design of the measurement-control device based on dsPIC33EP MCU is emphatically introduced. In software de- sign, programming algorithms for main parameters measurement, host competition strategy of master- slave control, communication protocol, and the main programming algorithms for capacitor protection configuration and action criteria are discussed.
