IEEE Screening Guide for Planned Steady-State Switching Operations to Minimize Harmful Effects on Steam Turbine-Generators

This document is a progress report describing the effect that steady-state switching can have on steam turbine-generators. A screening quantity AP is defined and it can be calculated in conventional transient stability simulations. Its purpose is to determine if a proposed switching event will result in negligible deterioration of turbine-generator components or whether the switching event should be investigated in greater detail. This document is intended as a planning tool. It is not intended to restrict the operation of the power system, but rather it is intended to promote dialogue between the turbine-generator manufacturer and the utility. The expression "turbine-generator as used in this guide applies to two and four pole steam turbine-generators.
