[Abstract]:The development of new energy is an important part of our country's energy development strategy, and the relevant national policies clearly encourage the development of new energy generation. Solar energy is the most abundant renewable energy, with unique advantages and great potential for development and utilization. Through the development of local solar energy resources, not only can provide a certain amount of clean electricity, Can also promote the vigorous development of local industries, with obvious economic and social significance. In this paper, Huaneng Yingkou thermoelectric 10MWp photovoltaic power generation project is designed and studied. Firstly, according to the meteorological data of three meteorological stations in Yingkou, Dalian and Shenyang, the solar energy resources, temperature, wind speed and other meteorological conditions were investigated carefully. Secondly, mainly according to the geological, meteorological conditions and solar energy resources of Yingkou area, how to select photovoltaic modules and photovoltaic sub-arrays suitable for the operation environment in this area, including the determination of the operation mode of photovoltaic system, The determination of optimum inclination angle and azimuth angle, the design of photovoltaic subarray, the cable connection design of photovoltaic module, the design of row spacing and column spacing, etc. Then, according to the situation of solar energy resource in Yingkou area and the current situation of Yingkou power network, the design scheme of electrical part is studied, the series calculation of solar cell module is carried out, the selection of inverter and DC distribution equipment is put forward, and the main electrical wiring scheme is designed. To estimate the annual power of the Internet, and then put forward a practical implementation plan; Finally, according to the current situation of Yingkou power network, the system access scheme is designed, and the protection configuration scheme of photovoltaic power generation system is designed according to the relevant regulations of national photovoltaic grid connection. The project is expected to provide 12308.01MWhs of electricity to the power grid every year, save 3951t of standard coal per year, reduce emissions of soot and SO2,NOX,CO2, ash, etc. It has obvious energy saving, environmental protection and social benefits.
