【摘要】：太陽能是清潔的可再生能源，太陽能發(fā)電是新能源中技術(shù)成熟、具備規(guī)模開發(fā)條件和商業(yè)化發(fā)展前景的發(fā)電方式之一。開發(fā)太陽能光伏發(fā)電是我國能源建設、實施可持續(xù)發(fā)展戰(zhàn)略的需要。因此，開展并網(wǎng)光伏電站發(fā)電系統(tǒng)研究具有重要的理論意義和實用價值[1]。本文以50MWp并網(wǎng)光伏電站發(fā)電系統(tǒng)為研究對象，，首先介紹了太陽能電池發(fā)電原理、應用，并進行了太陽能資源及建站條件的分析；通過對多種太陽能組件的型式選型、組件安裝及運行方式選擇、并網(wǎng)逆變器選型，完成了太陽能光伏子陣的發(fā)電系統(tǒng)設計，并對理論上網(wǎng)電量進行了計算；結(jié)合并網(wǎng)光伏電站接入系統(tǒng)設計及審查報告、進行變電站電氣系統(tǒng)一次部分、二次部分、通訊部分、消防部分的設計；對并網(wǎng)光伏電站的投資概算及收益進行了分析，并進行了社會效果分析，光伏電站的建設替代燃煤電廠的建設，可達到充分利用可再生能源、節(jié)約不可再生化石資源的目的，將大大減少對環(huán)境的污染，同時還可節(jié)約大量淡水資源，對改善大氣環(huán)境有積極的作用。研究成果對并網(wǎng)光伏電站設計有一定的指導作用。
[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.
