摘要

随着电力建设的快速发展和供需关系趋于平衡

火电机组利用小时数逐年下降

机组长期处于低负荷的"非经济负荷区"运行。文中分析研究了湖南省火电机组低负荷运行现状及对经济性的影响

从优化机组设备运行方式、加强设备技术改造等方面提出了提高低负荷运行经济性的有效措施。

Abstract

As power constructions develop fast

the relationship between supply and demand is tend to balance

the utilization hours（UTH） of the thermal power units is getting declined and power units are running under the condition of "uneconomical load area" in long term.The status quo of power unit low load operation and its influence on economical efficiency were analyzed.The ways to improve low-load economical efficiency such as optimizing units operation mode and carrying out equipment modification were put forward.
