Zusammenfassung: | To provide a power generation system capable of charging a capacitor with weak power of a plurality of power generation devices connected in parallel to a power conversion device and utilizing the power using no switch element.SOLUTION: A power generation system includes: power generation devices 21 to 2n; a plurality of diodes D1 to Dn (a connection box 5) for each preventing reverse flow to the power generation devices 21 to 2n; a converter 32 for converting generated power of the power generation devices 21 to 2n into power suitable for a load; and capacitors 31 connected to common wiring for connecting the connection box 5 and the converter 32. The converter 32 performs constant voltage control so that a capacitor voltage Vc of the capacitor 31 becomes a preset voltage command value VA.SELECTED DRAWING: Figure 1
【課題】電力変換装置に並列に接続された複数の発電装置の微弱電力を、スイッチ素子を用いることなく、キャパシタに充電して活用できる発電システムを提供する。【解決手段】発電装置21~2nと、発電装置21~2nへの逆流をそれぞれ防止する複数のダイオードD1~Dn(接続箱5)と、発電装置21~2nの発電電力を負荷に適合する電力に変換する変換器32と、接続箱5と変換器32とを接続する共通の配線に接続されたキャパシタ31と、を備える。変換器32は、キャパシタ31のキャパシタ電圧Vcが予め設定された電圧指令値VAになるように定電圧制御する。【選択図】図1 |
