摘要
以质量、能量守衡原理为基础,结合热力学、传热学、流体力学相关专业基础知识,以深圳广前电力有限公司M701型燃气-蒸汽联合循环机组配套的燃烧室为对象,在一定简化条件下,建立了燃烧室动态仿真模型,首次从机组整个热力系统的角度研究燃烧室动态特性及其对整个机组特性的影响。仿真试验表明:所建模型能够正确反映参照机组燃烧室的动态特性和全工况运行过程,整体模型运算稳定可靠,可直接应用于燃气轮机和联合循环机组的整体仿真系统模型的开发,还可为燃机控制系统的设计与分析提供良好的非线性子模型。
On the basis of the mass, energy conservation principle and elements knowledge of thermodynamic theory, heat transfer theory and hydro-dynamic theory, after reasonable simplification, a dynamic simulation model for a gas turbine combustor was developed, which the simulated object is the combustor installed in the M701F combined cycle unit in Shenzhen Guangqian Power Co., Ltd. For the first time, the dynamic characteristic of the combustor and its influence on the performance of the gas turbine power unit was discussed from the angle of the overall thermal system. The simulation tests show that the simulation model can correctly simulate the transient behavior and overall operating process of the combustor in the object unit, the iterative method applied in the models is stable. The dynamic simulation model can be directly used for the gas turbine or combined cycle unit simulator development, and is a good nonlinear sub-model for the control system design and analysis of the gas turbine.
