摘　　要：为解决330 MW机组DEH-ⅢA控制系统老化和转速测量精度不高的问题,将原DEH-ⅢA控制系统升级改造为DEH-V控制系统。改造后,DEH-V控制系统调试方便,转速测量精度提高到±0.1 r/min,解决了DEH控制系统老化和转速测量精度不高的问题,并提高了一次调频的合格率。In order to solve problems of control system aging and low speed measurement accuracy of the DEH-III A control system in 330 MW unit, the original DEH-m A control system is upgraded to the DEH-V control system. After the modification, the DEH-V system is convenient to be debugged,and the speed measurement accuracy is improved to ±0.1 rpm/min.,which not only solve problems of the control system aging and low speed measurement accuracy and but also improve the qualification ratio of primary frequency regulation.
