Operation Status

DSP-based intelligent split-phase self-adaption reactive power compensation controller was designed to real-time monitor the dynamic reactive power compensation of power grid parameters. The controller uses the capture unit and A/D conversion unit of DSP chip to respectively complete the power grid frequency measurement and power grid signal sampling, which simplifies the hardware architecture of the system, adopts split-phase dynamic reactive power compensation technology, and guarantees the realization of reactive power compensation via compensation capacitor switching when the three-phase load is unbalanced. The operation results showed that this controller could real-time monitor the parameters of power grid, accurately and rapidly switch the capacitor set with no impact according to the operation status of power grid, making the power factor of load stay within the reasonable range, improving the supply power quality.
