Calibration of power-system-simulation programs using disturbance data. Final report. [LOTDYS computer code]
The calibration of transient stability and long-term dynamic simulation programs is a concern to electric utilities because the results of these programs play a more important role in power system engineering studies. One of the most effective ways of validating a transient stability or long-term dynamic simulation program is to compare its performance with data that are recorded during a major system disturbance. This report describes past practices, ongoing developments, and future developments in this area. Seven past attempts at simulating major system disturbances with transient stability and long-term dynamic simulation programs are reviewed to assess their capabilities and limitations. Models for representing disturbance behavior of various system components, including generators, loads, transformers, turbines, and boilers, are reviewed, and needs for additional development are identified. Procedures that have been used for recording long-term dynamic response of variables for power plants, generators, loads, and the network are reviewed. Areas where the capabilities of modern energy control centers and data acquisition systems can be extended to enhance the task of calibrating a long-term dynamic simulation program are identified. Devices that have been used for recording power system synchronizing oscillations and past procedures for validating transient stability programs are also reviewed. The review encompasses the capabilities of devices, such as oscillographs, that have been traditionally available as well as several modern special-purpose units that digitally record voltage, current, megawatt, megavar, and frequency oscillations.
