水轮机调速器在功率闭环调节模式下的一次调频试验
摘要
水轮机调速器一般采用开度调节模式
但对于灯泡贯流式水轮发电机组
采用功率闭环调节模式具有更快的响应速度和更小的超调量。洪江水电厂6号机调速器采用功率闭环调节模式
在一次调频的试验过程中
对其调节系统静态和动态性能进行了认真的检测
优化了一次调频参数
检验了机组的一次调频能力。
Abstract
Hydraulic turbine governors usually use wicket gate opening adjusting mode
but for bulb turbines
the power closed loop adjusting mode have a faster response speed and smaller overshoot regulation.The power closed loop adjusting mode has been used in hydraulic turbine governor for Hongjiang hydraulic power station.In one primary frequency regulating test
the static state capability and dynamic capability of governor were checked and parameters of primary frequency regulation were optimized
proving the ability of primary frequency regulation.
