(GE-LSTG) MH Turbine Control Concepts
Course Overview
This learning doc emphasizes the GE MHC
systems. The LD describes the basic laws of steam turbine controls and
the relative importance of valve positioning. Detailed discussions on
speed control off line, speed load control while on-line, load limiters,
pressure control (limiters), and positioning the turbine steam inlet
valves. Topics will include operator interaction with the control system
and unit reaction to grid conditions and how responses may be limited.
All related alarms and alarm responses are included in this discussion.
