A desensitized controller for voltage regulation of power systems
- Electricite de France, Clamart (France). Direction des Etudes et Recherches
In this paper a robust linear voltage controller is proposed to improve power system stability and performance under varying operating conditions. This controller includes the automatic voltage regulator and the power system stabilizer. It limits the variations of the terminal voltage, damps the electromechanical oscillation and increases the excitation during and after a short circuit in all operating points. The design method chosen to improve the parametric robustness is desensitivity. It is the first time that a parametric robust design method has been applied to resolve the problem of voltage regulation. The method principles when the parameter is a vector, are presented. The desensitized controller has a simple structure and therefore can easily be implemented. The results obtained with a simulation software and with the Electricite de France Transient Network Analyzer show the good performance and the advantages of the controller with respect to various disturbances. This method can be applied to all kinds of generators, and is particularly well suited in the case of turbogenerators working in very different operating conditions.
