Title SOLAR POWER GENERATION SYSTEM, CONTROL DEVICE USED FOR SOLAR POWER GENERATION SYSTEM, AND CONTROL METHOD AND PROGRAM FOR THE SAME meetings
Abstract

Provided are a light power generation system, a control device, a control method, and a program whereby efficient power, which is controllable whether a power converter circuit includes a chalk coil or not, can be supplied even if sunlight irradiated onto a solar cell panel is partially shadowed. The maximum power detection unit (253) in a control unit (25) operates a MOSFET (242) in a power converter circuit (24) (for example, in a DC-DC converter) and open-circuits both ends of a solar cell panel (11) in the maximum power detection mode. After that, the maximum power detection unit (253) short-circuits both ends of the solar cell panel (11), detects a maximum power (Pmax) by monitoring the output power of the solar cell panel (11) during a period from the open state to the short-circuited state, and defines the voltage (Vpv) of the solar cell panel (11) as an optimal voltage (Vop) when detecting the maximum power (Pmax). In a tracking operation mode, the control unit (25) performs PWM control with respect to the MOSFET (242) by defining the optimal voltage (Vop) to be a reference signal. Operations are repeated between the maximum power detection mode and the tracking operation mode, which are described above.
