抽水蓄能电站运行能给电力系统带来多方面的效益。本文从抽水蓄能电站的主要功能——调峰、填谷作用出发,研究了抽水蓄能电站与火电站联合运行所取得的节煤效益。并以十三陵抽水蓄能电站为例,论述了抽水蓄能电站经济效益分析计算方法,证实了抽水蓄能不但有技术经济效益,而且节省煤,纠正了一般所说的费煤的概念。
Pumped storage power station operation can bring many benefits to the power system. In this paper, starting from the main function of pumped storage power station - peak shaving, filling effect, studied the pumped coal-fired power plant and coal-fired power plant operation achieved by coal-saving benefits. Taking Shisanling pumped storage power plant as an example, the paper analyzes the calculation method of economic benefit of pumped storage power station, confirms that pumped storage not only has technical and economic benefits, but also saves coal and corrects the concept of coal commonly called coal.
