Title:
SOLAR POWER GENERATION SYSTEM AND FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/111511
Kind Code:
A1
Abstract:
A solar power generation system comprises: a DC power supply including a solar cell (3); a power conversion device (2) for converting DC power output from the DC power supply to AC power; a voltage detection unit (5) for detecting voltage output from the power conversion device (2) to a power system (1); a current detection unit (6) for detecting current output from the power conversion device (2) to the power system (1); an effective power detection unit (7) for detecting effective power from the output of the voltage detection unit (5) and the output of the current detection unit (6); a mass-point system calculation unit (10) for calculating the angular frequency (ω) of the voltage output from the power conversion device (2) on the basis of the output from the effective power detection unit (7) and an output target value (Pref) of the effective power; an electric characteristic calculation unit (21) for calculating an output voltage target value (Ec) of the power conversion device (2) on the basis of the angular frequency (ω), a detection current value (IG), and a setting voltage value (Vref); and a power conversion control unit (14) for controlling the power conversion device (2) according to the output voltage target value (Ec).
