Abstract: Aiming at the problem of increase of the power loss and instability of grid voltage resulting from low load power factor of factory and the increase of reactive power which flow from grid to load, the principle of TSC dynamic reactive power compensation and the disadvantages of the traditional control strategy were studied. In addition, basic control strategy, “JiuYu diagram method” control strategy and fuzzy control strategy were summarized. A new control method based on the combination of fuzzy control strategy and improved “JiuYu diagram method” control strategy was put forward and simulated in Matlab. The results indicate that the improved control strategy based on the TSC which used in the whole working process of reactive power compensation can accurately and rapidly cast or cut capacitor and avoid oscillation and super compensation.
