Abstract

This paper outlines procedures and experience the author had on commissioning and field tuning ABB Unitrol P AVR and PSS of a 160 MW steam turbine. Field measurements are provided in the paper for demonstration of transient responses. In addition, UEL verification test was conducted and test method is described in this paper. Transient responses from computer simulations are also provided in this paper to demonstrate the techniques used by today´s power engineers. Comparisons between the field measurements and simulations show good matched. The tuned AVR and PSS parameters are provided for reference, and PSS frequency characteristics are presented.
