摘　　要：分析了独立能源系统的一般方案及其设计原则。提出了独立能源系统的评价准则,并对独立能源系统进行了模拟分析。模拟结果显示,在系统各设备运行参数完全相同的条件下,通过对余热锅炉补燃来增加系统冷、热输出的第二类能源系统的能耗率比,通过增大机组发电量并采用电制冷方式增大系统冷量输出的第三类能源系统的能耗率高,两类系统能耗率的差值随系统冷电比、热电比的增大而增大。补燃型余热锅炉效率的提高可明显降低第二类系统的能耗率。通过实例应用验证了模拟结果的准确性。General schemes and design principles for an independent energy source system were analyzed,and its evaluation criteria,presented.A simulation and analysis was performed of the energy source system in question.The simulation results show that under the condition of totally identical operating parameters of various equipment items in the system,the energy consumption rate of the second category energy source system,of which the cooling and heating energy output is increased by a complementary combustion in a heat recovery steam generator(HRSG),is higher than that of the third category energy source system,of which the cooling energy output is enhanced by increasing the power generated from the unit and by adopting an electric refrigeration mode.The energy consumption rate difference of the above two category systems will increase with an increase of the cooling/power ratio and heating/power ratio of the respective system.The enhancement of the complementary combustion type HRSG efficiency can obviously lower the energy consumption rate of the second category system.The relevant application cases have verified the accuracy of the simulation results.
