Abstract

In the Modern scenario, the naturally available resources for power generation are being depleted at an alarming rate; firstly due to wastage of power at consumer end, secondly due to inefficiency of various power system components. A Combined Cycle Gas Turbine (CCGT) integrates two cycles- Brayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall plant efficiency. This is accomplished by utilising the exhaust of Gas Turbine through a waste-heat recovery boiler to run a Steam Turbine. The efficiency of a gas turbine which ranges from 28% to 33% can hence be raised to about 60% by recovering some of the low grade thermal energy from the exhaust gas for steam turbine process. This paper is a study for the modelling of CCGT and comparing it with actual operational data. The performance model for CCGT plant was developed in MATLAB/Simulink.

摘要

在现代情况下，用于发电的天然可用资源正以惊人的速度枯竭；首先是由于用户端的电力浪费，其次是由于各种电力系统组件效率低下。联合循环燃气轮机（CCGT）整合了两个循环——布雷顿循环（燃气轮机）和朗肯循环（蒸汽轮机），目的是提高电厂的整体效率。这是通过利用燃气轮机的废气通过余热回收锅炉来驱动蒸汽轮机来实现的。燃气轮机的效率在28%至33%之间，通过从废气中回收一些低品位热能用于蒸汽轮机过程，可将其提高到约60%。本文是对联合循环燃气轮机建模并将其与实际运行数据进行比较的研究。联合循环燃气轮机电厂的性能模型是在MATLAB/Simulink中开发的。
