汽轮机数字式电液调节系统改造方案分析

摘要

首先研究了汽轮机调节系统的发展历史和应用现状，分析汽轮机调节系统进行数字式电液调节（DEH）改造的必要性和可行性。以承德环能热电有限责任公司的汽轮机数字电液调节系统升级改造工程为实例，论述了数字电液调节系统（DEH）的改造方案和控制功能，为系统的升级改造提供科学依据。%This paper studies the development history and the present condition of the turbine adjusting system. It works out the nessessity and possibility of the DEH transformation of turbine adjusting system. Then it analyses the example of digital electric hydraulic control system of Chengde Thermal Power Plant, gives the transformation scheme and the control functions of the digital electric hydraulic control system. It provides the scientific basis for the similar system' s promotion transformationo
