Testing & modeling of generator controls

The testing and modeling of generators, and their associated controls, is a complex topic. This is in part because of the variety of different generators and controls found on a practical power system, and the manner in which they interact during normal and abnormal power system operating conditions. There is a consensus within the industry that the development of accurate models for generator control systems is a key step in establishing operating-security limits and in simulating and understanding the operation of the system during disturbances. This paper presents the modeling requirements and the different criteria (location of critical stations, list of critical units, list of critical components, type of models, data to be collected, and the type of test to be performed) for testing and modeling of generators and their associated controls.
