摘要
针对电网中功率因数小、线路损耗大、电网利用率低等问题,提出了以型号为TMS320F28335的DSP控制芯片为主控制器的低压动态无功补偿装置,设计了控制系统硬件结构,并介绍了主控制器原理、功率因数补偿方式和过零触发电路。该装置经实际的电网测试,网络损耗降低,电路运行稳定,功率因数得到大幅提高,系统控制更加精确。
According to the reactive power in power grid such as small power factor, network loss, low utilization rate of power grid. This paper designs an intelligent dynamic reactive power compensation device based on TMS320F28335 as the main controller. The article designs the control system hardware structure. And it introduces principle of main controller, the power factor compensation mode and the zero trigger circuit. In the actual test in power grid, the circuit operation stability, and the power factor has a substantial increase, and the system controls precision.
