Research and Design of reactive power compensation capacitor switching devic
Abstract:This paper mainly low-voltage distribution network reactive compensation devices existing problems were analyzed and compared a variety of reactive power compensation policies and the shortcomings of their existence. Determine the use of the bus voltage. power factor determine the required amount of reactive power into the grid. We designed a micro controller STC9C52 and CS5643 energy measurement chip as the core of the reactive power compensation capacitor switching device. complete software and hardware reactive power compensation capacitor switching device simulation test was designed and built at ISIS 7 Professional Simulation Software environment simulation under different voltage. Power factor was simulated and tested reactive compensation devices the performance indicators to meet the design requirements.
Key words: Reactive power compensation; Control strategy; Hybrid control
