摘要：燃气一蒸汽联合循环机组具有较高的效率和环保特性，是发电领域的热点之一。联合循环的能耗特性会随环境条件和负荷条件变化而变化。考虑环境条件变化的燃气一蒸汽联合循环的机组变工况特性研究具有一定的理论意义和实用价值。分析研究燃气一蒸汽联合循环主要设备特性，采用差分进化法，结合某燃气-蒸汽联合循环6F发电机组的运行数据和设计数据对联合循环进行建模，挖掘出燃气一蒸汽联合循环中各参数之间的关系，进而得到燃气一蒸汽联合循环能耗随环境温度变化的规律，这对优化燃气一蒸汽联合循环性能具有重要意义。

Abstract: Gas - team combined cycle unit has higher efficiency and environmental protection characteristics, and is a current hot spot in the field of power generation.The energy consumption characteristics of the combined cycle vary with environmental conditions and load conditions. It is of theoretical significance and practical value to study the characteristics of gas steam combined cycle under consideration of the change of environmental conditions. Analyzing the characteristics of the main equipment of the gas - steam combined cycle and using differential evolution method, the gas -steam combined cycle is modeled by combining the actual operation data and design data of a gas steam combined cycle generating units 6F, obtaining the law of energy consumption of gas steam combined cycle with ambient temperature, which is of great significance to understand the overall performance of the gas steam combined cycle and optimize the power plant production.
