摘要
无功功率是保证电网安全可靠运行的重要指标,根据无功补偿器控制策略的不同。文中以PIC32MX764F128H单片机为核心,将无功功率作为主投切判据,设计了一种可根据负荷变化,通过控制晶闸管投切电容器组,实现对电网无功功率动态调节的补偿器。通过Simulink搭建仿真模型,试验结果表明,该补偿器的软、硬件设计合理,运行安全、可靠,能达到无功补偿设计的要求。
Reactive power is an important indicator to ensure the safe and reliable operations of the power network. According to the different control strategies of the reactive power compensator,a power control system is designed with the PIC32MX764F128 H single-chip microcomputer as the core and reactive power as the main criterion for switching to realize the dynamic adjustment of reactive power by controlling the thyristor switched capacitor. Simulink is used to build simulation model. Test results show that the compensator hardware and software design is reasonable and the system runs safely and reliably and meets the requirements of reactive power compensation design.
