Title:
FAULT DIAGNOSIS DEVICE AND FAULT DIAGNOSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2011/104931
Kind Code:
A1
Abstract:
Disclosed is a fault diagnosis device provided with: a sunlight state estimation unit (204) which uses actual output power that is output from storage and an output characteristics model that predicts output power from a sunlight state affecting power generation, and which estimates the value of the sunlight state closest to the actual output power for each power generation module as a sunlight state estimation value; a sunlight state spatial correction unit (206) which corrects the sunlight state estimation values in such a way that the sum of the sunlight state estimation values of the power generation modules contained in a storage of interest is within a range determined by the sum of sunlight state estimation values for adjacent storages that are adjacent in the lengthwise direction on the plane of the storage of interest, and obtains corrected sunlight state estimation values; and an output power fault determination unit (207) which determines that a fault has been generated when the difference between the sum of the expected output power, which is expected for the power generation modules and is calculated by using the output characteristics model and the corrected sunlight state estimation values, in the storage and the actual output power is equal to or greater than a threshold value and the actual output power is less than the expected output power.
