摘要：
A phase detection method without phase-locked loop based on reference frequency was proposed by some scholars to solve the defects of the traditional phase-locked loop method. However, it has problems such as a phase shift when the voltage frequency does not match the reference frequency and a slow dynamic response when the frequency fluctuates. As a result, a method of dual compensation phase detection is proposed for the above problems. Single-phase grid voltage is utilized to obtain a synchronization signal without a phase-locked loop. A phase compensation strategy is introduced to solve a phase offset caused when the frequency of the reference sine and cosine given by the controller in the phase-locked loop does not match the grid frequency.At the same time, in order to improve the dynamic response of the phase detection, q-axis voltage closed-loop feedback is proposed to calibrate compensation signal in real time. Finally, the mathematical model of a single-phase pulse rectifier is established.The proposed algorithm is verified via comparing the proposed algorithm with the uncompensated algorithm. © 2020, Power System Technology Press.
