摘要
以ZK2000型燃气轮机为研究对象,通过对其进行改造,引入太阳能光热转换模块、分体式回热器以及三通阀,提出一款克服传统光热发电缺点并降低燃料消耗的ZK2000太阳能燃气轮机。利用商业NPSS软件对比计算了ZK2000简单循环、ZK2000回热循环和ZK2000太阳能混合循环的性能,以青海省格尔木市作为实例分析ZK2000太阳能燃气轮机的可用性,并对影响系统性能的3个因素:太阳法向直接辐射强度、太阳能接收器压力损失和环境条件的影响规律进行分析,可为ZK2000太阳能燃气轮机的应用提供指导。并在ZK2000太阳能燃气轮机的基础上,以燃料消耗率为优化目标,分别对系统进行循环结构优化(增加ORC系统)和运行方式优化(变转速),结果表明,优化后系统可获得更低的燃料消耗。
In this paper, a ZK2000 gas turbine was taken as the study object. The solar thermal conversion module, split-body type recuperator and three-way valve were introduced to ZK2000 through modification, and a ZK2000 solar gas turbine was proposed to overcome the shortcomings of traditional solar thermal power generation and reduce fuel consumption. The performance of ZK2000 simple cycle, ZK2000 recuperative cycle and ZK2000 solar hybrid cycle were compared and calculated by commercial software NPSS. The Golmud of Qinghai Province was taken as an example to analyze the availability of ZK2000 solar gas turbine, and the influence law of three factors affecting the system performance: solar direct normal irradiance, solar receiver pressure loss and ambient conditions were analyzed, which can provide guidance for the application of ZK2000 solar gas turbine. On the basis of ZK2000 solar gas turbine, the cycle structure(adding ORC system) and operation mode(variable speed) of the system were optimized respectively with the fuel consumption rate as the optimization objective. The results show that the optimized system can obtain lower fuel consumption.
