モデル追従制御インバータによる風力発電系統連系の位相特性

Wind energy is a clean and renewable energy source. A wind generator using a PMSG can operate in maximum power point tracking (MPPT) mode. In addition, it has capabilities for fault ride through (FRT), active power and reactive power control issues, and voltage regulations. We have already proposed a model following controlled PWM inverter that exhibits robustness. The proposed inverter can output a sine wave current regardless of the rippling input voltage. This paper presents a numerical simulation analysis of the transient characteristics of the discrete-time model following controlled PWM inverter for a wind turbine generator system with a synchronized grid interface.
