APPARATUS AND METHOD FOR POWER GENERATION DIAGNOSIS OF SOLAR PHOTOVOLTAIC GENERATION MONITORING SYSTEM

摘要

The present invention relates to an apparatus and a method for power generation diagnosis of a solar photovoltaic generation monitoring system in which maintenance is facilitated by comparing the estimated amount of power generation according to temperatures and the quantity of solar radiation with the actual amount of power generation and diagnosing solar photovoltaic generation. The apparatus comprises: multiple solar photovoltaic generation units including a solar cell module for converting and outputting solar energy into electrical energy; a solar photovoltaic generation measurement unit installed in each of the solar photovoltaic generation units for measuring the air temperature, the temperature of the solar cell module, the quantity of horizontal solar radiation, the quantity of incident solar radiation, and the amount of power generation; a solar photovoltaic generation diagnosis unit for calculating a power generation operation rate of the solar photovoltaic generation units by estimating the amount of power generation of the solar photovoltaic generation units on the basis of the variety of information measured by the solar photovoltaic generation measurement unit and comparing the estimated amount of power generation with the actual amount of power generation; and a solar photovoltaic generation monitoring unit for receiving the variety of information diagnosed by the solar photovoltaic generation diagnosis unit and monitoring power generation status, observation, diagnosis, analysis, and reports.
