Claims (2)
- 風力タ−ビンで駆動される発電機の出力電力に基づいて得た交流電力を当該風力発電設備の発電電力として系統に供給する風力発電用電力変換装置であって、前記発電機としての同期発電機と、該同期発電機の出力電力を直流電力に変換するコンバ−タ手段と、変換された前記直流電力を所定周波数の交流電力に変換するインバ−タ手段と、変換された前記交流電力を演算する電力演算手段と、演算された前記交流電力と最大発電電力基準との差分を基に界磁電流補正信号を演算する電力リミット制御手段と、前記界磁電流補正信号を用いて前記発電電力が予め定められた最大発電電力を超える可能性がある場合に、前記インバ−タ手段の出力交流電力が前記最大発電電力を超えないように前記同期発電機の界磁巻線電流を制御するチョッパ制御手段とを有することを特徴とする風力発電用電力変換装置。
- 前記同期発電機の回転速度信号の大きさに応じて前記界磁電流補正信号の信号レベルを変化させ、前記界磁巻線電流の過度の抑制を制限する界磁電流補正信号リミッタを具備することを特徴とする請求項1記載の風力発電用電力変換装置。
