METHOD AND APPARATUS FOR DIAGONISING SOLAR GENERATING DEVICE BASED ON LABVIEW

摘要

Disclosed are an apparatus and a method for diagnosing a photovoltaic power generation facility using Labview. According to an embodiment of the present invention, measurement information of external environment factors received from a plurality of sensors disposed on prescribed positions of a photovoltaic power generation facility, a rated module current, and a rated module voltage are acquired. The rated module current and the rated module voltage are corrected using a calculation interaction formula and a calculation coefficient generated by considering a property between the rated module current and the rated module voltage according to the measurement information. Corrected rated power is derived from the corrected rated module current and the corrected rated module voltage according to a correction coefficient extracted by a standard test condition and a predefined correction interaction formula. The photovoltaic facility is diagnosed for each predefined diagnosis item based on the derived corrected power to process diagnosis results Into Labview data and display the Labview data. Analysis items for the diagnosis results including a photovoltaic power generation amount, aging loss, line loss, and a power conversion device are processed into a Labview data format. A derived analysis result of the photovoltaic power generation facility is displayed on a screen to easily diagnose the photovoltaic facility and improve precision and reliability for photovoltaic facility diagnosis results.
