CONTROLLER OF SOLAR TRACKING PHOTOVOLTAIC POWER GENERATION SYSTEM AND SOLAR TRACKING PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To minimize reduction of power generation amount due to retreat control.SOLUTION: A controller 4 of a solar tracking photovoltaic power generation system 1 including a solar cell 2, and drive means 3 for raising/lowering and turning the solar cell 2 so that the light-receiving surface 2b thereof tracks the sun further includes position detection means 11 for detecting the raising/lowering position of the solar cell 2, wind velocity measurement means 12 for measuring the wind velocity, a setting section 13 for setting a first wind velocity threshold V1 each time depending on the raising/lowering position of the solar cell 2 detected by the position detection means 11, and a control unit 14 performing retreat control by lowering the solar cell 2 with the drive means 3, when a wind velocity value measured by the wind velocity measurement means 12 exceeds the first wind velocity threshold V1.
