Title:
OPERATION POINT CONTROL METHOD OF PHOTOCELL, AND PHOTOCELL SYSTEM AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2016139378
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an operation point control method of a photocell having control stability, rapid response and tracking efficiency, and provide a method and a system associated with the operation point control method.SOLUTION: In a photoelectric cell system configured to output the output power of a photocell to a load side through a switch type power controller, with a duration ratio change width of switching as a two-stage fixed value, switching from a large change width to a small change width (from a high speed mode to high resolution mode) is performed, according to the fact that an operation point exceeds a maximum power point. Further the duration interval of duration ratio adjustment may vary according to a change amount of output power.SELECTED DRAWING: Figure 1
