Overview of 20 megawatt photovoltaic power generation project in Aineng temple, Huludao

     The 20MW photovoltaic power generation project is located in songgoutun village, Qianyu, sierbao Town, Lianshan District, Huludao City, Liaoning Province, with the geographic coordinates of 40 ° 48 '56.240 "north latitude and 120 ° 39' 9.811" east longitude. The project site has convenient transportation and superior geographical location. The annual sunshine hours are about 1918 hours, and the total solar radiation is 5668.16mj/m2. All power stations are installed with fixed supports, and the construction scale is 20mwp ground power station system.

     The project adopts the scheme of block power generation and centralized grid connection. The whole power generation system is composed of 16 photovoltaic power generation electronic systems of about 1.25mwp. Each 1.25mwp battery array adopts two 630kw inverters and one 1250kva box type transformer. Each square array is composed of solar cell modules in series and parallel. After the solar cell array is input into the primary lightning protection combiner box and DC distribution cabinet of the photovoltaic square array, it is inverted through the inverter. After the box type transformer is boosted, it is connected to the booster station. After the secondary boosting of 66kV through the main transformer, it is sent out to the T-connected 66kV TUANSHANZI line and sent to the 220kV TUANSHANZI substation system.

     After the completion of the project, the average power generation capacity of the power station in 25 years is 30.66 million kwh, which can save 4398 tons of national standard coal annually. The emission of SO2 and NOx (calculated by NO2) is about 587t and 55T respectively. The emission reduction of greenhouse gas CO2 is about 16716t.
