精确检测电网电压矢量相位角方法的研究
Study on the method of phase angle measurement of voltage vector in power network
摘要
Abstract
In order to realize the unity power factor of grid connected inverter ,the phase angle of the voltage vector of the power system with the phase locked loop technology is required . Because of the distortion of the voltage of the grid and the error in the sampling process ,and deviation problem caused by the detection of voltage vector phase angle of the grid ,an im‐proved method was presented to calculate the phase angle of the voltage vector of the grid ,and realize the digital phase lock by the software .The principle and implementation of the method are described in detail ,and not only the software phase locked loop is verified by Curve Draw , but also the correctness of the proposed method is verified on the experimental platform of three phase photovoltaic grid connected inverter .关键词
