正交变换在电网功率估计中的应用

A Use of Orthogonal Transform in Power Estimation

在电网监测过程中,常需要计算电网的复功率、电流电压之间的相位差等。本文提出利用正交变换的方法估计电网的复功率和相位差。仿真结果表明,该方法估计结果误差小,抗干扰能力强。

During the detection of the electronic net, the power and the angle difference usually need to be estimated. This papar surveys an algorithm based on orthogonal transform. The simulation results show that the algorithm above is an useful anti-jamming method.
