摘要
本文发展了一种电网电流的检测方法,在考虑电网电压畸变和基波电压初始相角的情况下,只需通过检测一相线路的电流、电压,就能有效地检测出电网基波有功、无功电流和任意次数的谐波电流,适用于电网无功功率补偿。
A novel detective principle and method for currents of power network are developed, in which the distortion of the voltage and the phase angle of fundamental voltage are considered and the fundamental active, reactive current and any term harmonic current can be effectively detected only by measuring single phase voltage and current. It is feasible to the compensation of the reactive power and harmonic currents and the diagnosis and protection of default.
