用于海军用途的联合循环的部分负载性能非常重要，并且它受到燃气轮机配置和负载控制策略的影响。本文旨在量化可变几何燃气轮机对船舶推进联合循环部分负荷效率的影响。此外，本文旨在开发适用于联合循环发电厂内各种组件的能源系统分析的部分负载模拟的方法和推导模型。研究了两种不同的燃气轮机配置：双轴航改配置和单轴工业配置。结果表明，通过使用可变几何燃气轮机，可以提高联合循环部分负荷性能。为了最大限度地减少航程燃料消耗，采用带有 VAN 控制的两轴燃气轮机的联合循环是集装箱船的一个有前途的替代方案，而带有 VGV 控制的单轴燃气轮机配置的循环对于油轮和运输船来说也是一个同样好的选择。
The part-load performance of combined cycles intended for naval use is of great importance, and it is influenced by the gas turbine configuration and load control strategy. This paper is aimed at quantifying the effects of variable geometry gas turbines on the part-load efficiency for combined cycles used for ship propulsion. Moreover, the paper is aimed at developing methodologies and deriving models for part-load simulations suitable for energy system analysis of various components within combined cycle power plants. Two different gas turbine configurations are studied, a two-shaft aero-derivative configuration and a single-shaft industrial configuration. The results suggest that by the use of variable geometry gas turbines, the combined cycle part-load performance can be improved. In order to minimise the voyage fuel consumption, a combined cycle featuring two-shaft gas turbines with VAN control is a promising alternative for container ships, while a cycle with single-shaft gas turbine configurations with VGV control is indicated to be an equally good choice for tankers and carriers.
