摘　　要：随着能源结构调整,对电力设备的环保性能提出更高要求。利用清洁能源天然气作为燃料的燃气-蒸汽联合循环机组成为清洁能源发电的主要设备,因此有必要研究分析联合循环系统的动态特性。本文搭建了包含喘振裕度以及NO_(x)排放等指标的燃气-蒸汽联合循环系统模型。同时,研究了在不同燃油流量、可调进气导向叶片(IGV)和环境温度下系统的性能变化情况。结果表明,系统输出功率受燃油流量变化影响最大;喘振裕度受IGV变化影响最大;涡轮前温度受环境温度变化影响最大;NO_(x)排放受燃油流量、IGV和环境温度影响均很大。本研究为联合循环发电机组的性能优化提供了理论依据和技术支持。With the adjustment of energy structure,higher requirements are put forward for the environmental protection performance of power equipment.The gas-steam combined cycle unit using clean energy natural gas as fuel has become the main equipment for clean energy power generation.Therefore,it is necessary to study and analyze the dynamic characteristics of the combined cycle system.In this paper,a gas-steam combined cycle system model including surge margin and NO_(x) emission is built.At the same time,the performance changes of the system under different fuel flow,adjustable inlet guide vane(IGV)and ambient temperature were studied.The results show that the output power of the system is most affected by the change of fuel flow.The surge margin is most affected by the change of IGV.The temperature before the turbine is most affected by the change of ambient temperature.NO_(x) emissions are greatly affected by fuel flow,IGV and ambient temperature.This study provides a theoretical basis and technical support for the performance optimization of combined cycle generating units.
