【Abstract】 The authors proposed a method to directlyregulate the voltage across the capacitor by thyristor switching device and presented the working principle and wiring of the proposed method. In addition, this paper put forward achanging method for different voltage taps in the secondarywinding of the auxiliary transformer, established amathematical model for the tap changing up to 9 orders and conducted a simulation for typical tap changing process. The simulation results show that under the most serious condition the current of tap changing is rather small. The comparisonbetween the proposed method and other reactive powercompensating methods indicates that the proposed method may possesses better performance and lower cost of construction.更多还原
