Title:
SOLAR POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/166787
Kind Code:
A1
Abstract:
The purpose of the present invention is to perform MPPT control by a simple method for individual strings in a solar power generation system that has strings 2 formed by serially connecting a plurality of solar cell panels 1, the DC power generated by the solar cell panels being converted by a power converter 3 connected to the strings 2, and supplied to a load or a power system. Therefore, in this solar power generation system, current measurement devices 4 for measuring the current in the strings 2 are serially connected to the strings 2, and reverse-flow-prevention diodes 5 are serially connected to the strings 2 in order to prevent the current in the strings 2 from flowing in reverse. In addition, a DC power source 7 for boosting the voltage in the strings 2 by a predetermined value is connected in parallel to the reverse-flow-prevention diodes 5 via switches 6, and a control device 8 is provided for performing control so that the switches 6 are closed and a voltage of predetermined value is supplied from the DC power source 7 to the strings 2 when the current measured by the current measurement devices 4 is equal to or less than a predetermined value.
