SOLAR PANEL POWER SYSTEM ABNORMALITY DIAGNOSIS AND ANALYSIS DEVICE AND METHOD BASED ON FHMM AND PREDICTION OF POWER GENERATION

A power generation system abnormality diagnosis and analysis device for diagnosing a solar power generation system in which plural modules are connected in parallel. The analysis device includes a total current detection module for providing a total current sequence data and an observed voltage value; an environmental information module for providing an environmental information; a FHMM calculation module for performing a FHMM calculation on the sequence data to obtain plural sets of first current inference values and extracting a set of second current inference values from the sets of first current inference values according to the environmental information and a current voltage history database; a database building module for recording an observed voltage value and the set of second current inference values; and a user feedback module for determining whether to issue an abnormality warning according to the set of second current inference values and the observed voltage value. 一种发电系统异常诊断分析装置，用以诊断由多个模块串列并联而成的
