摘　　要：以清远水利枢纽坝址处长系列逐日径流为基础,采用水能计算方法计算清远水利枢纽年均发电量,并与实际发电量相比较,误差较小,认为水能计算方法合理;广州北江引水工程取水量依次取1~10 m^3/s,计算其对清远水利枢纽发电效益的影响,计算结果表明广州北江引水工程取水对清远水利枢纽工程发电量影响在44~452万kW·h,占年发电量比例在0.11%~1.1%,且清远水利枢纽电量损失值与广州北江引水工程取水流量基本成正比关系。Based on the long series daily runoff of Qingyuan Water Conservancy Hub Project, calculates the power generation of Qingyuan Water Conservancy Hub Project with the method of hydropower calculation,Compared with the actual power generation,the error is small,and then the calculation method is reasonable. Analyzes the impact on the power generation of Qingyuan Water Conservancy Hub Project when the intake flow of Guangzhou North River Intake Project is from 1 to 10. The results illustrate that the power loss of Qingyuan Water Conservancy Hub Project is 0. 44 to 4. 52 million kilowatt hours,about 0. 11% to 1. 1% of annual output,and the power loss is proportional to the intake flow of Guangzhou North River Intake Project.
