Electrical Planning And Design Of Solar Photovoltaic Project Of Zhangye City In Gansu Province

There’s a great contradiction between rapid global economic development and energy demand and environmental protection,which is particularly prominent for energy production and consumption country like China with coal as the main source.An important way to solve this problem is to develop renewable energy-based energy,reduce fossil energy consumption and low carbon economy,which also led other high-tech and emerging industries to flourish and achieve strategic transformation of the national economy and industrial upgrading breakthrough.Solar energy is one of the best of today’s green energy,it has been more widely used by human beings.China’s photovoltaic power generation get leaps and bounds under China’s PV policy guidance and influence by global PV market.Gansu Province is one of China’s provinces that has abundant solar energy resources.Combination of solar energy resources and characteristics of photovoltaic power station construction,vigorously carry out the construction of solar photovoltaic power plants is an effective way to achieve new renewable energy development.This article identified solar photovoltaic project size and the need for project construction through comprehensive evaluation on solar energy resources,location,power system supply in Zhangye City in Gansu Province,etc.Firstly,the work researched PV system solutions,component selection,PV array scheme,etc.Then,planned fundamentals like main electrical wiring,protection,communication systems,etc,completed solar photovoltaic system project planning.This paper analyzes and calculates the annual power generation capacity and power generati on efficiency of the power station,and analyzes the photovoltaic power generation projects from t he profit and social effects,and gives the evaluation and inspiration:Development of photovoltaic power generation projects in Gansu is help to increase the proportion of renewable energy sources,optimizing system power structure,and there is no pollution,reduce environmental pressures,and it aslo has significant energy-saving,environmental and social benefits.The study not only have practical significance to Gansu Zhangye solar photovoltaic power station project,but also provide a theoretical basis for the construction of photovoltaic power generation system in the future.
