【摘要】：太阳能是清洁的可再生能源，太阳能发电是新能源中技术成熟、具备规模开发条件和商业化发展前景的发电方式之一。开发太阳能光伏发电是我国能源建设、实施可持续发展战略的需要。因此，开展并网光伏电站发电系统研究具有重要的理论意义和实用价值[1]。本文以50MWp并网光伏电站发电系统为研究对象，，首先介绍了太阳能电池发电原理、应用，并进行了太阳能资源及建站条件的分析；通过对多种太阳能组件的型式选型、组件安装及运行方式选择、并网逆变器选型，完成了太阳能光伏子阵的发电系统设计，并对理论上网电量进行了计算；结合并网光伏电站接入系统设计及审查报告、进行变电站电气系统一次部分、二次部分、通讯部分、消防部分的设计；对并网光伏电站的投资概算及收益进行了分析，并进行了社会效果分析，光伏电站的建设替代燃煤电厂的建设，可达到充分利用可再生能源、节约不可再生化石资源的目的，将大大减少对环境的污染，同时还可节约大量淡水资源，对改善大气环境有积极的作用。研究成果对并网光伏电站设计有一定的指导作用。
[Abstract]:Solar energy is a clean renewable energy, solar power generation is a new energy technology mature, with scale development conditions and commercial development of one of the ways of electricity generation. The development of solar photovoltaic power generation is energy construction in China. Therefore, the research of grid-connected photovoltaic power generation system has important theoretical significance and practical value. [1. This paper takes 50MWp grid-connected photovoltaic power generation system as the research object. Firstly, the principle and application of solar cell generation are introduced, and the solar energy resources and the conditions of building the solar power station are analyzed. Through the type selection of various solar modules, assembly installation and operation mode selection, grid-connected inverter selection, the solar photovoltaic sub-array generation system design is completed, and the theoretical power supply is calculated. Combined with the design and review report of grid-connected photovoltaic power station access system, the design of substation electrical system one part, two part, communication part, fire part design; The investment estimate and income of grid-connected photovoltaic power station are analyzed, and the social effect is analyzed. The construction of photovoltaic power station can make full use of renewable energy instead of coal-fired power plant construction. The purpose of saving non-renewable fossil resources will greatly reduce the pollution to the environment, but also save a large number of fresh water resources. It has a positive effect on improving the atmospheric environment, and the research results have a certain guiding effect on the design of grid-connected photovoltaic power station.
