摘要
Abstract
Aiming at the problems of aging equipment and low water energy utilization efficiency in Gaozhou Hydropower Station,a study on the efficiency-increasing and capacity-expanding renovation of hydroelectric generating units is carried out on the premise of keeping the characteristic parameters of the reservoir and the structure of the powerhouse unchanged.Through techno-economic comparison and construction risk analysis of three capacity expansion schemes,the 2×2100 kW scheme is determined as the optimal configuration.For turbine selection,the HL200-LJ-85 runner is adopted by comprehensively considering efficiency,cavitation performance and matching with embedded parts,while the generator,governor and auxiliary systems are upgraded accordingly.Five-year operation practice after renovation shows that the average annual power generation increased from 16.055 GW·h to 19.442 GW·h,with an increase of 21.1%.The operation stability and automation level of the equipment have been significantly improved.This case can provide a valuable reference for the technical renovation of similar hydropower stations.关键词
