Problems solved by technology

However, at present, relevant calculation and analysis methods are mainly determined by the experience analysis of designers, and the calculation results of water energy parameters are somewhat subjective and arbitrary, and when the census area is large and there are many potential station sites, the overall workload of water energy parameter calculation is relatively large. Large, relatively low work efficiency

Description

technical field [0001] The invention relates to a method for calculating water energy parameters of a pumped storage power station based on the maximum scale criterion. Background technique [0002] Pumped storage has the characteristics of flexible operation, fast start-up, and strong load tracking capability. Combined operation with new energy can significantly improve the utilization rate of new energy resources, and effectively alleviate the situation of curtailment of wind and light. Cooperating with nuclear power, it can guarantee the safety of nuclear power units. Stable operation, improve its operation safety and economy; under the development situation of UHV DC, pumped storage power station can be used as a supporting power source, enhance the ability of the power system to respond to accidents, and ensure the safe, reliable and stable operation of the power system. [0003] The development of pumped storage power stations in China follows the principle of unifie...
