Modelling and analysis guidelines for slow transients. II. Controller interactions; harmonic interactions

The first part of this three-part report explains the objectives of the task force and the scope of its report (1995). The first part also provides modelling guidelines for the investigation of small-signal torsional oscillations, large-signal shaft transient stresses, turbine-blade vibrations, and fast bus transfer based on the use of digital computer time-domain simulation methods. This paper provides modelling guidelines for the analysis of controller interactions, harmonic interactions, and resonance phenomena in power systems. Sample test systems and typical time-domain simulation results for each phenomenon are also provided.
