Abstract

A resistive, thyristor-controlled brake is used to damp transient torques in large thermoelectric generators supplying series-compensated transmission lines. Emphasis is placed on developing a suitable control algorithm and testing the algorithm through a wide variety of different operating configurations. Discrete-level generalized predictive control (GPC) is examined as one possible approach to optimal control of the brake. Some problems with implementation of GPC on the system are discussed. Prony analysis is used to identify system transfer functions, which are then related to control design considerations and robustness properties
