Abstract: This paper considers the fault-tolerant stabilisation of a power system over a wide range of operating conditions via excitation and governor controllers. A simple technique is presented to maintain stability when both controllers act together and when either one of the two controllers fails. The dynamics of a power system operating at various loads is treated as an interval (uncertain) plant. The problem of designing power system controllers with a general structure, which stabilise the interval plant, is converted to a simple stabilisation problem for only four Kharitanov polynomials (as compared to the 16 plant theorem with first order controllers). A single machine infinite bus system is considered to demonstrate the suggested technique. Stability tests show the robustness of the proposed controller.
