基于燃气轮机冷热电三联产系统的优化运行

The Optimal Operation of the System Which is Combined by Cooling,Heating and Power Based on the Gas Turbine

在燃气轮机的区域型联产系统中,由于调节模式和燃料电力价格标准的不统一,使得实际运行会造成大量浪费。为此选型GE LM1600燃气轮机,配备相应的溴化锂吸收式冷暖机和压缩式电制冷机,组成一个区域型能源站,通过建模仿真,分析主要设备的变工况特性,以系统每小时的经济花费为优化目标函数,计算出在不同调节模式和不同燃料电力价格比下的费用特性曲线。结果表明燃料电力价格比是影响系统运行经济性的关键参数,系统调节模式的选择应根据当时的燃料电力价格比作为参考依据。

The regional co-generation system which is based on gas turbine will lead to vast waste when it runs, for the non-uniform standard of regulation models and the price of electric and fuel. Therefore GE LM1600 is chosen as the gas turbine and correspondent lithium bromide refrigerators and compression-type refrigerating machines are equipped, then a regional power plant is formed. Through the modeling and simulating, the character of major equip- ments＇ variable working condition is analyzed, the cost per hour of system is regarded as the optimized objective func- tion. After calculating, the cost curve in different regulatory modes and different ratios between fuel and electricity price are obtained. It is concluded that the ratio between fuel and electricity price is the key parameter which effects system＇ s economic operation, and the choice of system＇ s regulatory mode must refer to the current ratio between fuel and electricity price.
