Household photovoltaic power station fault monitoring and early warning method

Abstract

The invention discloses a household photovoltaic power station fault monitoring and early warning method. The method comprises the following steps: collecting power generation data of a user power station at regular time; comparing the real-time data with the power generation information received by the power station of the user on that day and on that month, and judging whether the power generation data is abnormal or not; establishing a power station power generation model and a power station group in the same group, judging whether the abnormal data is a power generation fault, and if so, performing fault processing; establishing a fault pool, comparing the fault information with the existing fault types stored in the fault pool, and if the comparison is successful, carrying out intelligent fault processing; if the comparison fails, starting a manual fault processing flow; after the fault processing is finished, recording the fault information, and inputting the fault information into a fault pool; and carrying out the next round of data acquisition. According to the invention, remote monitoring of the photovoltaic power station can be realized, and remote control of the fault point of the household photovoltaic power station can also be realized, so that the fault point can be cut off in time when a fault is found, and the property loss of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a fault monitoring and early warning method for a household photovoltaic power station. Background technique [0002] Photovoltaic power generation is a power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and energy comprehensive utilization with broad development prospects. The grid-connected energy storage power generation system can be connected to the national grid. It advocates the principles of nearby power generation, nearby grid connection, nearby conversion and nearby use. And the problem of loss in long-distance transportation. At the same time, the remaining photovoltaic power can be stored in the battery, so that photovoltaic power generation can be fully utilized. [0003] Photovoltaic power stations are generally built on the roof or in remote area...

AI Technical Summary

Problems solved by technology

However, the existing monitoring platform is relatively simple for the fault analysis of the power station, and can only judge simple faults, such as power failure of the power station, line loss of voltage, etc., and cannot analyze detailed fault problems and provide solutions; in addition, its It can only realize remote monitoring, but cannot realize remote control, cut off and isolate fault points, etc.
