Abstract

Abstract:

Environmental temperature and pressure, which act as the operating condition of the steam power system, play an important role in the safety and economy of the whole system. The simulation model of a steam power system was established to analyze and discuss the characteristics of the system under different ambient temperature and pressure. The results show that auxiliary engine power, steam flow and fuel flow increase with the raise of environmental temperature. Also, auxiliary engine power, steam flow and fuel flow increase with the decline of environmental pressure.Moreover, a lower load of dynamic system leads to a greater proportion of auxiliary engine power.

Key words: steam power, environment condition, response pattern, process systems, model, dynamic simulation

摘要：

环境温度和压力作为蒸汽动力系统的自然工作条件，对于动力系统尤其是增压锅炉装置运行的安全性及经济性有重要影响。建立了蒸汽动力系统仿真模型，对不同环境条件下的动力系统运行特性进行仿真研究。结果表明：环境温度越高，涡轮增压机组辅机功率及蒸汽消耗量越大，动力系统燃油消耗量越大；环境压力越低，涡轮增压机组辅机功率及蒸汽消耗量越大，动力系统燃油消耗量越大；动力系统负荷越低，辅助汽轮机在为压气机提供功率时所占的比重越大。
