Abstract

The invention relates to the field of distributed photovoltaic technology, in particular to a method for analyzing a household photovoltaic shelter, which comprises the steps of: establishing a distributed power station basic information data archive, and inputting information; determining a calculation result after the data is substituted into a true solar time algorithm calculation model and aninverse distance weighted algorithm calculation module for calculation; if the determining results of the true solar time algorithm calculation model and the inverse distance weighted algorithm calculation module are both abnormal, determining that a shelter exists; otherwise, only recording determination result details; giving a warning prompt to the abnormal power station. The method can quicklyand accurately diagnose the power generation anomaly of a distributed photovoltaic power station, and can timely notify a user and an operation and maintenance worker, improves the abnormal treatmentschedule of the power station, reduces the operating cost of the power station, ensures the power generation reliability of the power station, and increases the generated energy and the revenue of the power station.

Description

technical field [0001] The invention relates to the field of distributed photovoltaic technologies, in particular to a method for analyzing household photovoltaic shelters. Background technique [0002] The invention patent technology relates to a method and device for analyzing occlusions applied to household photovoltaic systems. It mainly includes the following steps: establishing basic information of distributed power stations in household photovoltaic systems, establishing a benchmark power station model tree, and passing real solar time (true solar time) The solar day is divided into 24 true solar hours. This time system is called the true solar time. The true solar time is also called the apparent solar time, referred to as the apparent time. The true solar time is the hour angle of the center of the real solar viewing circle plus 12 hours. That is : true solar time=average solar time+true flat solar time difference) algorithm and reverse distance difference algorithm...
