摘要:
随着社会发展和产业结构的不断调整，用电结构不断变化，广东电力系统面临着日益加剧的调峰问题，系统调峰能力的不足成为制约电力发展的一个重要因素。利用热电联产机组参与调峰是解决上述问题的有效途径。文章从热电联产机组的建模出发，研究发电热耗、供电气耗、热电比与联合循环供电出力、供热量之间的关系，得出影响机组调峰能力的因素及调峰范围，通过对热电联产机组调峰能力的分析，提出热电联产机组应对电力系统调峰的运行模式。 Abstract:With the social development and industrial structure adjusting constantly, the changing in electricity structure, Guangdong power system is facing a growing problem on peak-shaving capability, the lack of power load has become an important factor restricting the development of electric power. To involve cogeneration units in peak shaving is an effective way to solve the problem above. In this paper, by modeling the cogeneration units, We study the different relationship between combined cycle net output, heat supply and the generating heat rate, the power supply gas consumption, the heat-electricity ratio, and conclude the factors which affect the peak shaving regulating capacity and the range of peak shaving. Base on the analysis of peak-shaving capability of the cogeneration units, we can know the operating mode of regulating peak-load of the power system.
