The Composite 90kvar Continuous Reactive Device Based on Variable Voltage Source

本文将与工频同相位、同频率的可调电压源与补偿元件相串联实现无功补偿,改变串联补偿元件性质和大小,可实现对容性或感性无功的连续调节,从而使被补偿装置的功率因数达到最佳值。该方法不产生谐波污染且补偿电压源的容量仅为最大补偿无功的14。已研制成功混合式90kvar、0.4kV实验装置一台,实验结果证明了本文提出方法的正确性。

The variable voltage source with the same phase and frequency as the power is connected to compensation component in series, changing its compensation document can continuously adjust the capacitive and inductive reactive power, so the best value of power factor of the compensated device is obtained. The harmonic pollution does not exist and the capacitance of the voltage source is only equal to the one fourth of the maximum reactive power compensation. The composite 90kvar and 0.4kV experimental equipment has been developed; the experimental results show that it is correct.
