面向高海拔地区变频抽蓄配置关键技术研究
Research on Key Technical Configuration and Adaptability of Variable Frequency Pumped Storage for High-Altitude Areas
摘要
Abstract
Due to the high sediment content,violent head fluctuations,and frequent low-pressure cavitation in high-altitude areas,traditional fixed-speed units are unable to adapt to the complex and changing operating environment of the plateau.This paper,based on the Xizang region,proposes a variable-frequency pumped-storage system configuration scheme that is adapted to the complex environment of high altitude areas.The system is centered around variable-speed operation of a doubly-fed induction motor,anti-sedimentation structural design of the pump-turbine,and intelligent control strategies to enhance dynamic response capabilities and operational reliability under variable operating conditions.Then,through typical operating condition comparisons and full life cycle cost modeling,the scheme's comprehensive performance in terms of operating efficiency,equipment life,and operation and maintenance costs is systematically evaluated.The research results show that the distributed variable-frequency pumped-storage system configuration scheme proposed in this paper has significant technical advantages and economic feasibility in high-altitude areas,and can effectively support the large-scale access and regulation of clean energy.关键词
