Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation systems, and in particular to a self-replaceable module power generation component power station and a working method thereof. Background Art

[0002] A photovoltaic power generation system (PV) is a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation into electrical energy. As a sustainable new energy source, solar energy is gaining increasing attention worldwide for its pollution-free and renewable nature. In recent years, my country's photovoltaic power generation industry has experienced rapid development, with the installed capacity of photovoltaic power stations continuously increasing. As more and more large-capacity photovoltaic power stations are directly connected to the power grid, the interaction between photovoltaic power generation systems and the grid has become increasingly complex. Among solar power generation technologies, photovoltaic cell power generation systems are currently the most widely used. A grid-connected photovoltaic power generation system uses photovoltaic modules to convert received solar radiation energy into high-voltage DC power through high-frequency DC conversion. After inversion by an inverter, it outputs a sinusoidal AC current to the grid that is in phase and frequency with the grid voltage and current.

[0003] Photovoltaic power stations can be divided into centralized photovoltaic power stations and distributed photovoltaic power stations according to their installed capacity. Distributed photovoltaic power stations are mostly installed on the roof of the factory building and adopt a flat installation method. This installation method usually has the following defects during the later operation and maintenance of the power station:

[0004] 1. To increase the utilization rate of the factory roof, photovoltaic panels are installed closely together, with few aisles for maintenance personnel to inspect. When damaged panels need to be replaced, they need to step on the working photovoltaic panels to reach the destination, increasing the risk of hidden cracks and damage to the photovoltaic panel surface;

[0005] 2. PV panels are installed over a wide area. When a power station malfunctions, it is difficult to immediately determine the exact location, and troubleshooting takes a long time.

[0006] 3. Each photovoltaic module is fixed on the roof track by fastening bolts. Disassembly and assembly takes a long time, affecting the overall maintenance efficiency of the photovoltaic power station. Summary of the Invention

[0007] In view of the technical problems existing in the background technology, the present invention provides a self-replaceable modular power generation component power station and working method. This scheme adopts a new photovoltaic component installation method, which can find the specific fault point in the first time when the power station is operating abnormally.
