Two area LFC model reduction

The present work deals with the reduction of a two area non-reheat turbine´s 7^th order model into lower order. The large order model may not be possible to tune and control on-line on a real time basis. It is, therefore, necessary to reduce the model of the 7^th order system into a lower dimensional model, which can be handled and tuned easily. In this paper, the authors have used the bilinear Schwarz approximation for reduction of the two area LFC model of 7^th order to a 2^nd order system. It is observed that for a 2^nd order reduced model the response of the system is nearly the same as the original system and settles like the original system at around 24 sampling time of 1 msec
