Abstract

Conventional power system stabilizers (PSSs) for generators are designed by linearization under one operating point. So they might not always work effectively after a large power system change due to disturbances. We have been developing nonlinear control systems which can operate effectively under various kinds of system conditions. We designed a nonlinear optimal excitation control (NOEC) system using an exact linearization approach for a one machine-infinite bus model. Confirmation tests of the prototype controller were carried out using a real time digital simulator (RTDS) to evaluate dynamic performance of the developed control system, and effectiveness of the controller was confirmed.
