Abstract
To solve the stability problem of low head and high flow mixed flow water turbines,Jinghong Power Station has taken measures such as throttling of the top cover pressure relief pipe,forced air supply to the top cover,and optimization of the start-up rules of the governor,based on existing conditions.This paper mainly elaborates on the influence of top cover pressure relief throttling,top cover forced air supply,and governor start-up rules on the stability of water turbine operation.关键词
