摘要

以某350 MW热电联产机组为研究对象

建立了考虑阀点效应的汽轮机变工况模型

设计了适用于热电解耦的吸收式热泵

研究了机组通过热电解耦辅助新能源消纳的深度调峰特性。结果表明:采用吸收式热泵解耦可有效提升热电联产机组的深度调峰能力

新增深度调峰量最大可达62 MW

调峰节煤量变化范围在0~28 t/h;受阀点效应影响

同一调峰负荷下调峰节煤量呈非线性变化

最大变化幅度可达1.1 t/h;解耦后单位调峰节煤率在400~506 g/(kWh)

变化幅度达106 g/(kWh);热电联产机组采用吸收式热泵解耦时应尽可能运行在单位调峰节煤率高的区域

以最大限度节省煤耗。

Abstract

Taking a 350 MW cogeneration unit as the research object

an off-design model considering valve-point effect was established

and the absorption heat pump suitable for heat-power decoupling was designed. The deep peak shaving characteristics of the unit to assist renewable energy accommodation through heat-power decoupling were studied. Results show that the absorption heat pump decoupling can effectively enhance the deep peaking capacity of the cogeneration unit. The maximum newly added deep peaking capacity can reach up to 62 MW

and the coal saving capacity for peak shaving varies from 0 t/h to 28 t/h. The coal saving capacity for peak shaving under the same peak shaving load changes nonlinearly

and the maximum change amplitude can reach 1.1 t/h. After decoupling

the coal saving rate for peak shaving varies from 400 g/(kWh) to 506 g/(kWh)

and the variation amplitude is 106 g/(kWh). It is suggested that in the case of absorption heat pump decoupling

the cogeneration unit should be run in the area with high coal saving rate for peak shaving to achieve the maximum coal saving.
