【Abstract】 The Controller for fundamental harmonic reactive power with dynamic compensation based on the industrial personal computer in the low-voltage power distribution network, is described. The controller’s hardware structure, the method of rapidly detecting fundamental harmonic reactive power and its circuits, the on-off control schemes of thyristor trigger circuit and condenser are illustrated emphatically. The actual problems of real-time detection, rapid response and higher reliability which are satisfied by the controller; are solved. With the controller, the quality of power supply is raised, and the safety of the power distribution network and its economic operation are guaranteed.更多还原
