基于抽水蓄能电站调度的电力系统节煤减排效应分析

Analysis of coal saving and emission reduction effect of power system based on the regulation of pumped storage power station

在全球日益关注能源和环境问题的今天,对清洁能源进行合理开发已成为世界能源建设的共识,其中抽水蓄能电站因具备技术成熟,调峰、调压、调相功能强等特点,在世界清洁能源开发建设中得到认可。抽水蓄能电站开发与运营管理在面对气候变化多样、节煤减排要求高的新形势下,需科学合理安排抽水蓄能调度运行机制,科学合理安排抽水蓄能在电力系统中的工作位置,更好发挥抽水蓄能电站节煤减排作用。通过对抽水蓄能电站不同运行方案进行分析,分析不同负荷曲线特性下抽水蓄能工作位置的差异,分析随着抽水蓄能不同工作方式的改变,分析其对电力系统中其他电源运行方式的影响,进而分析电力系统的燃煤消耗。该研究成果理论意义与实用价值均很大,可为我国抽水蓄能科学可持续开发建设提供参考依据。

In the world pay more and more attention to the energy and environmental issues of today,the reasonable exploitation and utilization of clean energy has become the consensus of the construction of energy in the world,where the pumping energy storage power station with mature technology,peak shaving,adjustable pressure characteristics of strong function of PM,in the world the development of clean energy construction recognized. Pumped storage power plant development and operations management in climate change diversity,coal saving face high requirements under the new situation,scientific reasonable arrangements for pumped storage power dispatch mechanism,scientific and reasonable arrangements for pumped storage location in the power system,and give better play to the pumped storage power station coal saving effect. This paper mainly through the pumped storage to different operation schemes of the power plant are analyzed,and analyzed under the different load curve characteristics of pumped storage can work position difference,analysis with pumped storage power to work in different ways,analysis the influence of power system in other power operation mode ring,and then analyzes the consumption of coal in the power system. The theoretical significance and practical value of the research results can provide reference for the sustainable development and construction of pumped storage in China.
