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.
