摘要
某电站混流式机组在高水头运行时调速器发卡,造成机组负荷调节过程缓慢,机组退出一次调频,影响机组正常运行。对可能产生该运行缺陷的各种原因进行了具体分析,同时通过现场试验,计算了该机组的导水机构力特性数据,提出了水轮机导叶在某些负荷工况下拒动的具体解决措施。
The regulating systems of Francis turbines in a hydropower station occur jamming faults when running in high water head, and leads to the abnormal operation of unit with a slower load regulation and no role on primary frequency regulation. The possible reasons of fault are analyzed herein, and combining to local tests, the force characteristics of the guide-vane apparatus are calculated. The solutions are also proposed for eliminating jamming fault under some load conditions.
