三相逆变器并联的模型预测直接磁链控制
Model Predictive Direct Flux Control of Parallel Three-phase Inverters
摘要
Abstract
Aiming at the problems of conventional droop method,such as frequency and voltage deviations,virtual flux was introduced to the droop controller. The active power and the reactive power were allocated by drooping the phase angle and virtual flux respectively,moreover,the droop control and the model predictive control of the three-phase inverter were combined,and the output reference flux and phase of the droop controller were tracked by the model predictive direct flux control(MPDFC)which avoided the use of PI controllers and PWM modulators. While the load power between parallel inverters could be divided equally,and the frequency characteristics of the system was improved and the dynamic characteristics of parallel inverter system was improved significantly. The proposed method is verified by simulation and experiment.关键词
