摘要
针对汽轮机DEH控制系统电源的稳定可靠性进行了研究,提出了一种DEH控制柜供电的合理方式。结合某电厂汽轮发电机组DEH电源的改进实施,表明改进后的DEH系统电源工作稳定,取得了良好的效果,有效地降低了DPU电源的故障率。
An improved power supply of DEH control system has been put forward in the light of the stability and reliability of the electric-hydraulic control system for turbine. Results show that the improved DEH system power supply is quite stable, which has effectively reduced the fault rate of DPU power supply after modification of DEH system for the turbine in a power plant.
