摘要
燃气轮机进气温度影响燃机的输出功率和热效率,温度控制最终在于控制燃气轮机进气温度。利用燃气轮机进气温度和燃气轮机排气温度的关系,测量燃气轮机排气温度,间接求得燃气轮机进气温度,引入控制逻辑对燃气轮机排气温度的各项保护和控制曲线作了分析。并且研究了外部环境条件对温度控制的影响,基于实际工作数据,对温度控制参数的调整给出说明。分析表明:PG9171E型燃气轮机主要参数测点的准确性和工作环境的变化对其温度控制有着重要影响。
The inlet gas temperature of the gas turbine affects the turbine＇ s output power and its thermal efficiency, while the temperature control of the turbine is eventually realized through the inlet gas temperature control. In this paper, in consideration of tile relationship between the inlet amt exhaust gas temperatures, the exhaust gas temperature is measured to indirectly obtain the inlet gas temperature. The control logic is introduced to analyze the protections and control curves of the exhaust temperature. In addition, the impact of the external ambient conditions on the temperature control is studied, from which the adjustment instruction on the temperature control is presented based on practical operation data. The analysis indicates that in the gas turbines of PG9171E type, the accuracy of major measurement data anti the changes of the ambient conditions have great effect on its temperature control.
