摘要
结合国内某F级燃气轮机电厂机组性能试验及长期运行数据,形成了工况分类及稳定性分析方法和基于运行数据可实时校准的热力模型,并以此对电厂实际运行工况进行了批量性能计算。以出力指标为例对电厂性能进行连续长期监测和异常分析,以可视化界面展示了整机及部件的性能监测功能,形成了适用于F级发电用重型燃气轮机的在线性能监测系统。这套监测系统不仅能实时监测燃气轮机的性能变化,还能将其修正至ISO标准工况,以此收集长时间连续可比的燃气轮机性能指标数据,为机组性能指标状态的分析提供依据。研究成果可为燃气轮机电厂精准性能数据分析及在线监测提供参考。
Based on unit performance test result and long term operation data of an F-class gas turbine power plant,analysis method of working condition classification and stability were formed,and thermal model with function of real-time calibration based on operation data was established.Adopting this model,batch performance calculation of actual operation conditions was conducted.Using the power index of the plant as an example,long term monitoring and abnormal analysis were carried out,and the performance monitoring function for the whole unit and components was displayed on the visual interface,thereby,an online performance monitoring system suitable for F-class heavy-duty gas turbine power generation was established.With this monitoring system,not only the real-time monitoring of gas turbine performance change could be realized,but also the correction of performance to ISO operation conditions could be conducted.Thus,performance indicator data of gas turbine with long term,continuous and comparable features were collected,which could provide aid for condition analysis on performance indicators of unit.The research results can provide reference for accurate performance data analysis and online monitoring of gas turbine power plants.
