Abstract
Description
目的は、無効電力の調整範囲を拡大したパワーコンディショナを提供することにある。
そこで、メガソーラ100は無効電力補償装置700を備える。無効電力補償装置700は交流電圧を系統に供給する際の無効電力を補償する。その補償量は、逆潮流の状態や系統の電圧変動に基づいて時々刻々と変動する。
無効電力補償装置700には例えばシャントリアクトルを使用し、市場で流通しているものを転用することが可能である。リアクトル上位に設けた開閉器のみを制御して無効電力補償機能を実現することで、制御を簡素化できる。
電力制御回路53は、系統に逆潮流する電圧に基づく電力を、交流電圧値VACに基づいて制御する。その出力は電流・電圧制御回路51と、PCS30の主制御部44と、他のPCSの電力制御回路とに出力され、無効電力補償のための力率制御に用いられる。
