【摘要】：大力开发新能源是我国能源发展战略的重要组成部分,国家相关政策明确鼓励新能源发电的发展。太阳能是资源最丰富的可再生能源,具有独特的优势和巨大的开发利用潜力,通过开发当地的太阳能资源,不仅可以提供一定量的清洁电能,还可以推动当地各产业的蓬勃发展,具有明显的经济和社会意义。本文设计与研究了华能营口热电10MWp光伏发电项目。首先,根据营口、大连、沈阳三个气象站的气象资料对厂址的太阳能资源、温度、风速等气象条件进行了仔细的调研;其次,主要根据营口地区的地质、气象条件及太阳能资源状况研究如何选择适合本地区运行环境的光伏组件及光伏子阵的设计与布置,包括光伏系统运行方式的确定、最佳倾角和方位角的确定、光伏子阵设计、光伏组件电缆连接设计、行间距和列间距设计等;然后,结合营口地区太阳能资源状况及营口电网现状,研究电气部分设计方案,进行太阳能电池组件串联计算,提出逆变器及直流配电设备选型,设计电气主接线方案,估算年上网电量,进而提出切实可行的实施方案;最后,根据营口市电网现状,设计了系统接入方案,并根据国家对光伏并网的相关规定,设计了光伏发电系统保护配置方案。本项目建成后预计每年可为电网提供电量12308.01MWh,年节约标准煤3951t,减少烟尘、SO2、NOX、CO2、灰渣等排放,具有明显的节能、环保和社会效益。
[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.
