光伏电站交流侧评估测试分析研究

目前,可再生能源受到了各国政府的高度重视,太阳能作为诸多永续利用的清洁能源中的一种,其开发和利用价值已成为各国可持续发展战略中的重要组成部分。选取了上海航天宁东一期100 MWp光伏电站项目具体实例,针对升压站交流侧一定数量并具有代表性的设备进行测试,运用科学的测试方法并对试验数据进行详细的整理分析,结合数学理论算法,最终计算出光伏电站交流侧典型日功率损耗率及电站发电效率,找出影响发电量的因素和解决办法。为光伏电站提供第一手数据资料,并对后期运维提出提供科学、合理、完善的管理及建议。

Analysis and Research on the AC Side Evaluation Test of Photovoltaic Power Stations

At present,renewable energyresources receive much attention from the governments of all countries in the world.The exploitation and utilization value of solar energy,one of many clean energy resources for sustainable utilization,becomes an important part of the sustainable development strategy of various countries.Taking the specific example of Shanghai Aerospace Ning Dong Phase Ⅰ 100 MWp photovoltaic power plant,this paper introduces tests made in a scientific way on a certain number of representative units at the AC side of the boosting station,as well as detailed analysis of the test data.By means of mathematical theoretical algorithm,typical daily power loss rate at the AC side of the photovoltaic power station as well as its generating efficiency is finally calculated,and factors affecting the generating capacity and solutions are found.Thus,first-hand data are provided for photovoltaic power stations,and suggestions for complete,reasonable and scientific management are provided for future operation and maintenance.
