Problems solved by technology

It can be seen that the power generation of photovoltaic power plants needs to be improved. When the photovoltaic panels work at high temperatures, the open circuit voltage will drop sharply with the increase of temperature, and at the same time, it will cause a serious shift in the charging operating point, which will easily cause the system to be damaged due to insufficient charging; When the temperature of the photovoltaic panel rises by 1°C, the maximum output power of the crystalline silicon solar cell decreases by 0.04%, the open circuit voltage decreases by 0.04% (-2mv / °C), and the short-circuit current increases by 0.04%. A power generation optimization system for photovoltaic power plants, which cools the working photovoltaic panels to increase the power generation of photovoltaic power plants

Abstract

The invention relates to the technical field of photovoltaic power generation, in particular to a power generation capacity optimization system of a photovoltaic power station. The system comprises aphotovoltaic module for absorbing sunlight and converting solar radiation energy into electric energy, wherein the photovoltaic module is formed by connecting solar cells in series or in parallel; a storage battery pack for storing the electric energy generated by the photovoltaic module, wherein the photovoltaic module is connected with the storage battery pack through a photovoltaic controller to perform over-charge and over-discharge protection for the storage battery pack; an inverter connected with the storage battery pack to convert a direct current to an alternating current; and a cooling cycle unit connected with the photovoltaic module to perform cooling and temperature reduction of the photovoltaic module. The photovoltaic module is cooled by cooling water circulation to greatlyimprove the utilization of the photovoltaic module, optimize the power generation system of the photovoltaic power station and improve the power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a power generation optimization system of a photovoltaic power station. Background technique [0002] Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components to connect to the grid and transmit power to the grid. Photovoltaic power plants are currently the green power development energy projects that are most encouraged by the state. The advantage of photovoltaic power generation is that it is less restricted by region, because the sun shines on the earth; photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need to consume fuel and erect transmission lines to generate electricity and supply power on site, and the advantages of short construction period. Photovoltaic po...
