汽轮机及热装置性能评估系统研究

以某石化电厂双抽凝汽式汽轮机及热系统为研究对象,开发了以“热力参数诊断”为中心的旋转机械热力性能评估体系。通过对该汽轮机组运行性能和经济性能的计算分析,实时显示汽轮机组工作状态、当前热经济指标、当前工况下的节能潜力及热设备能损诊断结果,提出优化运行建议,并从热力学角度为电站设备的状态监测和预知性维修提供科学依据,实时指导汽轮机组经济运行。

Study on the evaluation system of performance for the steam turbine and heat equipment

We have developed a thermal performance evaluation system for rotating machinery focused on thermal parameter diagnosing on the research of the double extraction condensing steam turbine at a petrochemical enterprise.By calculation analysis for the running and economic performance of this unit,we can show its real-time running state,thermoeconomic behavior,energy-saving potential and energy-loss analysis at current condition.From these,not only can we present operation optimization suggestions which can be the scientific gist of power plant unit's condition monitoring and precognition maintenance,but also can we real-time guide engineers to economically operate the steam turbine unit focused on thermodynamics.
