改革开放以来,我国工农业生产发展迅速,作为工农业生产动力的电力工业也有了很大发展。但电力系统负荷的峰谷差也越来越大;而高温高压大容量机组只宜在额定出力附近带固定负荷,不适宜作调峰调频机组;另外,我国除西北和东北电网外,多数电网中的火电比重很大,尤其处于我国的工业心脏地区的华东电网火电已超过25000MW,而水电容量仅3000MW 左右,调峰调频的矛盾尤为突出。“八·五”期间国家虽然在积极筹建浙江天荒坪大型抽水蓄能电站(6×300MW),但不可能在短期内从根本上解决峰谷差大这一矛盾。因此,各地区都在积极筹建中小型抽水蓄能 Since the reform and opening up, the industrial and agricultural production in our country has witnessed rapid development, and the power industry, which has been the driving force behind industrial and agricultural production, has also made great progress. But the power system load peak-valley difference is also getting bigger and bigger; while high-temperature and high-pressure high-capacity unit should only be in the vicinity of the rated output with a fixed load, not suitable for peak-adjusting FM unit; In addition, our country except Northwest and Northeast Power Grid, In particular, the thermal power of East China Power Grid, which is located in the industrial heartland of China, has exceeded 25,000MW while the hydropower capacity is only about 3,000MW. The contradiction between peak and peak frequency modulation is particularly prominent. During the “8th Five-Year Plan” period, although the state is actively planning the construction of a large-scale pumped storage power plant in Tianhuangping, Zhejiang Province (6 × 300MW), it is impossible to fundamentally solve the contradiction between peak and valley deficit in the short term. Therefore, all regions are actively planning to build small and medium-sized pumped storage
