在大电力系统的远景发展中,确定汽轮机单位机组的容量是很重要的。要在保证供电可靠性的基础上,使机组在电力系统发展的各个阶段中达到最经济地运行。分析这个问题时,应该考虑这样一些基本条件,即:系统的容量及其增长速度,设备运行条件及其事故解列的可能性,在选择容量不同的机组时设备的造价、热效率、运行费用以及对输电线路投资的影响
In the long-term development of large power systems, it is important to determine the capacity of turbine units. On the basis of guaranteeing the reliability of power supply, the unit will be able to operate economically at all stages of power system development. When analyzing this issue, it is necessary to consider such basic conditions as the capacity of the system and its growth rate, the equipment operating conditions and the possibility of accidental disassembly. When selecting units with different capacities, the equipment cost, thermal efficiency, operating costs and Impact on transmission line investment
