Upgrading To Fully-Electric Actuation and Control of Steam Turbines
Abstract
The use of an electric actuator for steam turbine governor valve operation is a cutting-edge technology in steam turbine control. With this design, the use of turbine oil for turbine speed control purposes is eliminated. This paper discusses the upgrade of critical mechanical drive steam turbines to fully electric control and actuation for improved controllability, efficiency and reliability.
The application at Saudi Aramco presented in this paper is pioneering in the Oil & Gas industry and the first regional application of this technology. Mechanical-drive installations in an Oil & Gas application environment present additional challenges to electric actuator retrofits; compared to other traditional applications, such as power generation. Moreover, the harsh weather conditions surrounding this pilot application called for extra precautions and special designs.
