Abstract

The optimization of the heating load operation of large co-generation units in thermal power plant was described, and the evaluation method of maximizing total relative economic benefit for thermal power plant was put forward. It is shown that this method can provide objective economic benefit of district heating operation conditions, and the benefit has no relationship with the concrete energy allocation method used for heating and electricity. It is shown that under the condition of boilers full load operation the optimized heating load scheme is related to the electric power response characteristics with change of the heating steam supply for the individual cogeneration unit. An example of heating load optimization for 2 existing 330MW cogeneration units was put forward in detail. It is shown that, the electric power response characteristics with change of the heating steam supply for the individual cogeneration unit, especially the slope of the characteristic curve determines the heating load optimization results. The cogeneration unit with lower changing slope should be dispatched in higher priority.

火电厂大型热电联产机组热负荷运行优化

阐述了火电厂大型热电联产机组热负荷运行优化问题，提出了火电厂总相对经济效益最大化的评价方法。结果表明，该方法能够提供区域供热运行工况的客观经济效益，且效益与具体的供热和用电能量分配方式无关。结果表明，在锅炉满负荷运行的情况下，优化的供热负荷方案与各热电联产机组随供热汽量变化的电力响应特性有关。详细介绍了2台现有330MW热电联产机组的热负荷优化实例。结果表明，单个热电联产机组的电力响应特性随着供热供汽量的变化，特别是特性曲线的斜率决定了热负荷优化的结果。变化斜率较小的热电联产机组应优先调度。
