Identifying Power Models State Space Techniques

This paper describes a numerical technique for identifying the pertinent transfer functions of multi-machine power systems. The method described herein will enable the system analyst to form a compact model of a complicated linearized multi-variable system with a minimum amount of manual algebra. The state space form of system representation is used to obtain the required transfer functions which in turn could be used to perform studies on any of the plant controllers. An example from the area of power system control is used to illustrate the efficiency of this particular technique.
