 en Decoupling of Double Extraction Turbo-Unit by Nonlinear Multivariable Inverse System Method
LI Haorong, LI Liqin, LI Donghai, SONG Zhaoxing, WANG Wei

Abstract

A multivariable inverse nonlinear control scheme is developed to decouple the strongly nonlinear double extraction steam turbo-unit, improving the transient stability of the power and heating system. Computer simulation tests show that not only does the control scheme achieve satisfactory decoupling of the high and low pressure turbines and the electric power, remarkably improving the transient stability, but also the design is very intuitive and concise

Keywords
