SIMULATION OF TRANSIENT CONDITIONS IN AUTONOMOUS ELECTRICAL-POWER SYSTEMS WITH CURRENT LIMITING DEVICES

This paper considers the theory and methods of computer studies of unb alanced transient conditions in autonomous power systems with current- limiting devices. Features of the mathematical model allowing for unba lanced conditions in the current limiting process are described. The m odel is based on new methods for transformation and solution of node v oltage equations and also on the proposed methods for allowing for the effect of current limiting devices (CLD). Some principles of rational simulation of an arbitrary structure and efficient algorithmization o f processes with due account of the phase equation of a circuit contai ning a CLD are substantiated. Some validated forms of special software for modelling autonomous power systems with an arbitrary structure ar e presented.
