OBJECTORIENTED MODEL TRANSFORMATION OF LINES IN WHOLE TRANSIENT SIMULATION

For building models of transmission lines to simulate whole transient, this paper coordinates the travelling wave model, the lumped parameter model and the quasisteady state model by dynamic characteristics of lines and makes use of OOP to build the selfadaptive model of lines. This model describes whole transient of lines and has characters of high precision, less time complexity and reliable transformation criterion. It can be used in studies of overvoltage, shortcircuits, interactions between AC/DC systems and transient stability
