Title:
DIAGNOSITIC DEVICE OF PHOTOVOLTAIC POWER GENERATION THROUGH OUTPUT TREND ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2020/166804
Kind Code:
A1
Abstract:
The present invention relates to a device for diagnosing the state or the like of photovoltaic and building integrated photovoltaic (BIPV) power generation devices and, more particularly, to a diagnostic device of photovoltaic power generation through output trend analysis, wherein the diagnostic device diagnoses the state of a specific photovoltaic power generation device by comparing the difference in output generated within grouped photovoltaic power generation devices through trend analysis of output generated during the same period in the past through machine learning, or the like, rather than state diagnosis through comparison of actual output of generated power with a calculated output predictive value of the specific photovoltaic power generation device, and at this time, processes information collected on the basis of information such as failure history and maintenance history of each photovoltaic power generation device for output information collected from the photovoltaic power generation devices, and minimizes error information on output trend through information such as weather information and environmental information of a region where each photovoltaic power generation device is located, thereby enabling precise grouping and improving the accuracy of state diagnosis therethrough.
