太阳能和风能是大自然馈给我们的两种最重要的天然能源，也是取之不尽的可再生能源，太阳能是地球上一切能源的来源，没有太阳，世间万物都将不复存在，而风能则是太阳能在地球表面的另外一种表现形式，地球表面的不同形态(如沙土地面、植被地面和水面)对太阳光照的吸热系统不同，从而在地球表面形成温差，这种温差就形成了空气对流，即风能。然而在各自的发电领域存在不足。Solar energy and wind energy are the two most important natural energies given to us by nature, and they are also inexhaustible renewable energy. Solar energy is the source of all energy on the earth. Without the sun, everything in the world will cease to exist, and wind energy It is another manifestation of solar energy on the earth's surface. Different forms of the earth's surface (such as sandy ground, vegetation ground and water surface) have different heat absorption systems for sunlight, thus forming a temperature difference on the earth's surface. This temperature difference is formed. Air convection, that is, wind energy. However, there are deficiencies in their respective power generation fields.

本发明的技术解决方案是：Technical solution of the present invention is:
一种薄膜电池光伏电站与风电场互补系统，其特征是：包括非晶硅电池光伏方阵，非晶硅电池光伏方阵与防雷汇流箱连接，防雷汇流箱与光伏并网逆变器连接，光伏并网逆变器与交流母线连接；有风力发电机组，风力发电机组与控制器连接，控制器与风机并网逆变器连接，风机并网逆变器与交流母线连接；交流母线接入三相交流电网，成并网系统；交流母线接入双向逆变器，双向逆变器与蓄电池连接，成独立系统；一个控制系统对上述并网系统、独立系统的切换进行控制。A complementary system for a thin-film battery photovoltaic power station and a wind farm, which is characterized in that it includes an amorphous silicon cell photovoltaic array, the amorphous silicon battery photovoltaic array is connected to a lightning protection combiner box, and the lightning protection combiner box is connected to a photovoltaic grid-connected inverter Connection, the photovoltaic grid-connected inverter is connected to the AC busbar; there is a wind turbine, the wind turbine is connected to the controller, the controller is connected to the wind turbine grid-connected inverter, and the wind turbine grid-connected inverter is connected to the AC busbar; the AC busbar It is connected to the three-phase AC grid to form a grid-connected system; the AC bus is connected to a bidirectional inverter, and the bidirectional inverter is connected to the battery to form an independent system; a control system controls the switching between the above-mentioned grid-connected system and the independent system.
所述三相交流电网与电站监控系统连接。The three-phase AC power grid is connected to the power station monitoring system.
本实用新型结构合理，无空气污染、无噪音、不产生废气物。薄膜电池光伏电站与风电场互补发电系统弥补风电和光电在资源上的缺陷。其优势在于利用了太阳能和风能在时间上和地域上的互补性。白天太阳光最强时，风很小。晚上太阳落山后，光照很弱，但由于地表温差变化大而风能加强。在夏季，太阳光温度大而风小，到了冬季，太阳光强度弱而风大。太阳能和风能在时间和地域上的互补性使风光互补发电系统在资源上具有最佳的匹配性。The utility model has the advantages of reasonable structure, no air pollution, no noise, and no waste gas. The complementary power generation system of thin-film cell photovoltaic power plants and wind farms makes up for the resource defects of wind power and photovoltaics. Its advantage lies in the utilization of the complementary nature of solar energy and wind energy in time and area. During the day, when the sun is at its strongest, there is little wind. After the sun sets at night, the light is very weak, but the wind energy is strengthened due to the large temperature difference on the surface. In summer, the sun is hot and the wind is low, and in winter, the sun is weak and the wind is strong. The complementarity of solar energy and wind energy in terms of time and region makes the wind-solar hybrid power generation system have the best matching in terms of resources.
薄膜电池光伏电站与风电场互补发电系统提高了土地的利用率，在风机下安装薄膜电池光伏电站(风机的遮挡和阴影之外的区域)。The complementary power generation system of the thin-film battery photovoltaic power station and the wind farm improves the utilization rate of the land, and the thin-film battery photovoltaic power station is installed under the wind turbine (the area outside the shelter and shadow of the wind turbine).
薄膜电池光伏电站与风电场互补发电系统在并网公用一套升压系统，节约设备投资，如三相380VAC或AC10KV升压系统。Thin-film battery photovoltaic power station and wind farm complementary power generation system share a booster system in the grid connection, saving equipment investment, such as three-phase 380VAC or AC10KV booster system.
薄膜电池光伏电站与风电场互补发电系统可以针对风力发电波动较大与薄膜电池光伏发电较平稳进行互补，从而大大提高的电能的质量和电网的稳定性。The complementary power generation system of thin-film cell photovoltaic power station and wind farm can complement the large fluctuation of wind power generation and the relatively stable thin-film cell photovoltaic power generation, thereby greatly improving the quality of electric energy and the stability of the power grid.
薄膜电池光伏电站与风电场互补发电系统可以大大降低发电成本，每度电的发电成本接近1元左右，基本接近火力发电的成本。The complementary power generation system of thin-film cell photovoltaic power station and wind farm can greatly reduce the cost of power generation. The cost of power generation per kilowatt-hour is close to 1 yuan, which is basically close to the cost of thermal power generation.
薄膜电池光伏电站与风电场互补发电系统合理性保证了风光互补发电系统的可靠性，为新能源的大规模推广创造了良好的条件。The rationality of the complementary power generation system of thin-film cell photovoltaic power plants and wind farms ensures the reliability of the wind-solar hybrid power generation system and creates good conditions for the large-scale promotion of new energy.
