摘要
以槽式光热电站为研究对象,针对试验工况、试验边界参数、试验仪器、全厂发电效率的计算和修正,以及测量不确定度等内容开展研究,给出了短期稳态工况全厂性能考核试验的方法。结合某50 MW槽式光热电站实例,基于其设计及运行数据,对试验方法进行模拟应用和验证。结果表明:该试验方法具有实用性;测量不确定度分析也为今后改进测量方法、提升测试精度提供了依据。
Taking the utility-scale parabolic trough solar power plant as the research object,the research was carried out on the test conditions,test boundary parameters,test instruments,calculation and correction of power generation efficiency of the whole plant,and measurement uncertainty,etc.A method of plant-wide performance test under short duration steady-state conditions was given.Combined with the example of a 50 MW utility-scale parabolic trough solar power plant,the test method was simulated and verified based on its design and operation data.Results show that the test method is practical,and the analysis of measurement uncertainty also provides a basis for improving the measurement method and improving the test accuracy in the future.
