River cascade development represents a crucial model in hydropower engineering, involving the sequential layout and integrated utilization of multiple hydropower stations. During the planning and design phases of such projects, comprehensive considerations must be made regarding water resource efficiency, environmental impact, ecological conservation, and socio-economic benefits. This paper explores planning and design methodologies for river cascade hydropower projects, analyzes synergistic effects between stations and reservoir operation strategies, and demonstrates practical applications through case studies. Through systematic analysis, it proposes integrated planning solutions to enhance water resource utilization efficiency and sustainable development, providing theoretical support and practical guidance for engineering design and decision-making in related fields.
