摘　　要：华能大连电厂2号机组汽轮机DEH数字电液控制系统设计改造,在沿用原有低压透平油系统及OVATION控制系统的基础上,改造重点为寻求一种新的、稳定的与原有低压透平油系统及OVATION控制系统相匹配的控制卡件。经理论论证及实践证明方案可行。不仅能尽量保留原有运行安全稳定的设备,并且简化了改造思路,节约了改造成本。Design retrofitting of DEH system for No. 2 unit in Huaneng Dalian Power Plant, which focused on a new , stable control cards matching with the original low pressure turbine oil system and the OVATION control system. It proves that this scheme is feasible through？ theoretical arguments and practice. It not only retains the safe and stable operation of the equipment as much as possible , but also simplifies the transformation idea and saves the cost of reconstruction.
