中文摘要:
      针对基于RS485总线的功率因数分布式补偿系统设计,阐述了无功补偿控制的原理以及分布式补偿的工作原理,进行了基于单片机控制的主从机软硬件设计,硬件采用模块化设计,实现智能控制模式,并对主从机通信规约、无功功率算法、以及电容投切控制原理进行了详细介绍,无功功率算法采用基于FFT变换的方法。实现了投切电容的智能化控制。
英文摘要:
      According to the power factor distributed compensation system design based on RS485 bus, this paper makes an exposition on the principle of reactive power compensation control and distributed compensation, designs the hardware and software of master-slave machine based on single chip microcomputer,the hardware adopts modular design,implementing intelligent control mode, and introduces communication protocols based on master-slave machine, the calculation of reactive power and capacitor switching on-off control principle. The reactive power algorithm is made by FFT transform method. The intelligent switching on-off control for capacitance is realized.
