REXA执行器在100MW汽轮机数字电液控制系统中的应用

Application of REXA actuator in digital electro-hydraulic control system of 100 MW steam turbine

将REXA电液执行器应用在100MW汽轮机组的数字电液控制系统改造中,并以杠杆反馈代替传统的液压反馈,提出一种新型的机组油动机控制方式,取得了满意的改造效果。该系统已在佳木斯发电厂100MW汽轮机数字电液拧制系统上获得成功应用。

A new type electro-hydraulic servo-valve control mode for the governing system of stram turbine was developed, i.e. to apply REXA electro-hydraulic actuator to the retrofit of digital electro-hydraulic(DEH) control system for 100 MW steam turbine, and to replace the traditional hydraulic feedback with leverage one., with the positive retrofit result achieved. This system has been successfully applied to the DEH control system of 100 MW steam turbine in Jiamusi Power Plant.
