This course has been designed for individuals who are new to steam turbine-generator operations and maintenance. It also provides an excellent review for individuals who have been involved with steam turbine-generators, but have not received formal training. In this course we discuss the basic theory of operation and apply that theory to a discussion of components that immediately follows. If one is to operate, maintain, or manage steam turbine generator functions then one needs to know why is works as it does, what are some of the design differences, and what is the significance of the various components. Nozzles, blades, shells, rotors, valves; all are covered as to their function. On the generator; frame, core, armature windings, rotor, field windings, and exciter: all are covered as to their fundamental function.
Topical Outline includes: Steam Turbine Operating Principles, Component Descriptions, Steam Valves, Unit Descriptions, Intro to Operations, Turbine Auxiliary Systems, Generator Operating Principles, Generator Component Descriptions, and Generator Auxiliary Systems.

HPC's instructional staff on this topic is significant. The materials were developed by those who have been working on steam turbine-generators their whole career
