Electrical Design Of Fu Xian Agricultural Greenhouses 30MW Photovoltaic Power Plant

Photovoltaic greenhouse is a new way of development of agricultural land use, It is on land space comprehensive development and utilization of crops or livestock in the greenhouse and roof solar photovoltaic component in photovoltaic roof. This way can not only provide a suitable environment for the growth of crops and livestock and temperature, but also solves the problem of the current photovoltaic power generation to reduce the difficulties, at the same time, also can put photovoltaic agriculture as tourism projects for the tourists. According to regulations, the electrical design of solar photovoltaic power plant standards, combined with China's current good photovoltaic industry policy in Shuangliao, serving first town actual natural conditions, provide more agricultural greenhouse 30 MW photovoltaic power plant electrical design optimization.First of all, this paper studies and analyzes the development of photovoltaic power generation at home and abroad. At home and abroad has been a certain scale of agricultural photovoltaic power station project, which contains the photovoltaic agricultural greenhouses, animal husbandry, aquaculture, fishing, light and other complementary. Relevant departments have issued relevant policies, in the next 5 years plan to support the use of 2 million poor people in photovoltaic power generation, so that every household to bring a significant economic income.Secondly, this paper studies and analyzes the solar energy resources, geological conditions and power systems in the area where the photovoltaic power station is located. Shuangliao service before the town of light time is longer, which belongs to the solar energy resource rich areas, the use of arable land, geological conditions suitable for the development of photovoltaic power generation projects, and the distance from the power load center closer to the power grid access. According to the actual situation in the paper, the optimization design scheme is described in detail through comparison and calculation.Again, according to the characteristics of the service, the paper made the electrical design of photovoltaic power plant. The electric design of the photovoltaic power station of the agricultural greenhouse can satisfy the stability and reliability of the power generation system, so as to ensure the connection is simple and clear, and the operation and maintenance can save time and effort. In the economic aspect to ensure the cost of investment in the economy, operation and maintenance costs are reasonable, and will be considered in the late expansion. PV power plant is mainly divided into two areas of agricultural greenhouses photovoltaic field and booster stations, respectively, for each region of the electrical system and electrical system for two times. Electrical design of a system mainly includes the design of electrical wiring scheme, the selection of main electrical equipment and distribution equipment layout design, etc.. The design of the two electric system mainly includes circuit and equipment protection, power distribution equipment control wiring and control system design.Finally, this paper according to the first agricultural greenhouse 30 MW photovoltaic power plant electrical design, summarize and complete the electrical design, elaborates the design results, and the future development of photovoltaic power plant project in agriculture.
