DYNAMIC-MODELS FOR FOSSIL FUELED STEAM UNITS IN POWER-SYSTEM STUDIES

A working group on Prime Mover and Energy Supply Models for System Dynamic Performance studies under the IEEE System Dynamic Performance Subcommittee was established in 1987 to collect technical information on dynamic characteristics of prime mover and energy supply systems that can affect power system performance during and following disturbances such as faults, loss of generation or loads and system separation. A principal objective of the working group is to develop prime mover/energy supply models for use in power system simulation programs. The last endeavor in this area was the IEEE Committee report (Ref. 1) in 1973 entitled "Dynamic Models for Steam and Hydro Turbines". This paper presents an update of models on fossil fired steam turbines including boiler effects and special speed control logic. It does not replace the previous IEEE Committee Report containing much valuable data on turbine models and their parameters. It should be considered as complementary to that reference expanding the models to account for special turbine control and boiler effects.
