摘要

The availability of inexpensive base load power from independent power producer has caused electric utilities to cycle their large steam turbines in an effort to reduce overall generation cost. Over the years, it has not been possible to accurately simulate the frequency response of a power station when large generators trip. Comparisons of disturbance monitoring records and their simulation using modeling have shown this discrepancy. The principal reason for this large discrepancy was that a large percentage of thermal unit turbines and governors were not properly modeled. This article develops a new turbine-Governor modeling and simulation technique of a steam-Turbine including the creation of system database based on disturbance monitoring and supervision control and data acquisition recording. This resulted in prediction of response with greater accuracy.
