Anomaly detection method for residential rooftop photovoltaic power station

Abstract

The invention discloses an anomaly detection method for a residential rooftop photovoltaic power station. The method comprises the following steps that 1, a standard source power station multi-parameter device and a residential power station electric energy device acquire data and upload the data to an anomaly processor; 2, the anomaly processor confirms that the standard source power station is in a high-quality state; 3: a county operation and maintenance center anomaly processor sets a compensation coefficient for the data uploaded by the residential power station electric energy device; 4:the anomaly processor checks an abnormal county residential power station; and 5, the anomaly processor pushes the abnormal residential power station information to an operation and maintenance unit.The county has the same climatic condition and a high-standard source power station is built. A local automatic patrol inspection operation and maintenance system guarantees that the standard sourcepower station is always in a high-quality state. The county residential power station electric energy device is low in cost and can be widely promoted. In a full-scale state, data analysis and judgment are performed, and the abnormal power station is determined within three days and the operation and maintenance workers are notified to maintain the abnormal power station, so as to ensure the stable power generation of the residential power station.

Description

technical field [0001] The invention belongs to the field of new energy patrol inspection operation and maintenance, in particular to a method for abnormal inspection of residential roof photovoltaic power stations. Background technique [0002] Photovoltaic power generation has gone through three stages. [0003] The first stage is that photovoltaic power generation is used in aerospace, lighthouses, and areas without electricity in Tibet. Off-grid structures are mostly used to highlight reliability. [0004] The second stage is a large-scale ground power station covering an area of ​​more than ten square kilometers and dozens of square kilometers in the western slopes, hills, and subsidence areas of mining areas. Photovoltaic panels and electrical equipment are installed close to the ground, and operation and maintenance workers walk or drive operation and maintenance vehicles along designated areas. Path visual inspection. [0005] The third stage is the stage of distri...

AI Technical Summary

Problems solved by technology

The inspection box is installed more than 1 meter away from the inverter, and the wireless communication module operates stably. However, the multi-circuit terminal voltage integrated collector costs more than 1,000 yuan, and the initial installation cost is high. It is difficult to install photovoltaic power stations on the rooftops of every resident.
