技術說明

本發明提供一種改善相位與振幅之方法，包含模型建立步驟、相位補償步驟、振幅補償步驟以及補償資訊產生步驟。模型建立步驟係建立對應換流器電路之換流器模型。電壓命令被輸入至換流器模型而產生實際電壓資訊。相位補償步驟係對電壓命令的相位命令資訊及實際電壓資訊運算而產生補償相位資訊。振幅補償步驟係對電壓命令的振幅命令資訊及實際電壓資訊運算而產生補償振幅資訊。補償資訊產生步驟係產生補償電壓命令，並輸入補償電壓命令至換流器模型而產生實際補償電壓資訊。藉此，縮減電壓命令與實際電壓資訊之間的差值。 A phase and amplitude improving method is proposed. The phase and amplitude improving method includes a model establishing step, a phase compensating step, an amplitude compensating step and a compensation information generating step. The model establishing step is performed to establish an inverter model corresponding to an inverter circuit. A voltage command is inputted to the inverter model to generate an actual voltage information. The phase compensating step is performed to compute a phase command information of the voltage command and the actual voltage information to generate a compensating phase information. The amplitude compensating step is performed to compute an amplitude command information of the voltage command and the actual voltage information to generate a compensating amplitude information. The compensation information generating step is performed to generate a compensating voltage command, and the compensating voltage command is inputted to the inverter model to generate a compensating actual voltage information. Thus, the phase and amplitude improving method of the present disclosure can decrease an error between the voltage command and the actual voltage information.
