摘要

The control and safety systems control and protect the steam turbine. In the past these systems were from the mechanical type. In course of time there was a change to hydraulic systems and today we have pure electro-hydraulic systems with microprocessor based closed loop and protection circuits. No additional mechanical back up devices are installed.
