The construction site (altitude: 431m) of Longi (Pucheng) 40 MW PV power plant project is located at Liujiagou Village, Yongfeng Town, Pucheng County, Shaanxi Province. Covering a total area of some 1,484 mu, the current project has an installed capacity of 40MWp and is equipped with mono-crystalline solar modules. In addition to its 40 PV arrays, this PV power plant also has a booster station in its southwest area, where there is a complex, staff dormitories and 10kV indoor power distribution facilities.
The project involves the installation of the following facilities: 40MWp PV modules, thirty 2*500kW inverters, ten 1MW inverters, 40 box-type transformer substations and 2,000-ton equipment supports. In order to effectively increase the power generation capacity and raise the project's yield rate, through multiple discussion and argumentation, we conclude that fixed adjustable system and automatic tracking system should be adopted to help install project-use equipments.
Upon completion, this PV power station can offer 58.58 million kWh to the power grid per year. Compared with a thermal power plant with the same power generation capacity, it can save 19,300 tons of standard coal (based on the average standard coal consumption of 330g/kW•h) and subsequently reduce the emission of various air pollutants. In particular, it will reduce 3,439.58 tons of S02; 56,200 tons of CO2; 1,695.62 tons of NOX, as well as 935.78 tons of smoke and dust on a yearly basis. Meanwhile, it will also save a huge amount of fresh water.
