东风发电厂通过充分利用现有设备状况及资源,成功地运用了 A/D 和 D/A 技术,将上游水位和下游水位先送至计算机监控系统的 LCU 装置,通过对公用 LCU 和调速器进行编程,计算出水头值后分别送到3台调速器,调速器采集到水头后作用于导叶开度/开限,不同的水头对应不同的导叶空载开度值和最大开度限制。提高了调速器的控调性能,同时减免了运行人员随时要跟踪和修改水头值等操作。
Dongfeng Power Plant successfully utilized the A / D and D / A technologies to make full use of the existing equipment and resources and sent the upstream and downstream water levels to the LCU unit of the computer monitoring system. Through the analysis of the common LCU and speed governor After programming, calculate the head value and send it to 3 governors separately. After the governor collects the water head, it acts on the opening / opening of the guide vane. Different water heads correspond to different guide vane open-load values and maximum open Degree limit. Improve the governor of the governor performance, while reducing the operator at any time to track and modify the head value and other operations.
