ISA 77.14.01 – Fossil Fuel Power Plant Steam Turbine Controls

This standard addresses steam turbine governor controls and overspeed protection of steam turbine generators in fossil power plants. Specifically excluded from consideration are single valve and controlled extraction turbines, mechanical drive turbines, automated startup/shutdown systems, turbine supervisory instrumentation, steam bypass systems, and turbine water induction prevention (TWIP) systems.

The purpose of this standard is to establish the minimum requirements for functional design specifications of steam turbine control systems for use in fossil fueled power generation plants.
