TRANSPUTER IMPLEMENTATION OF ADAPTIVE-CONTROL FOR A TURBOGENERATOR SYSTEM

The paper describes the design and implementation of digital self-tuni ng automatic voltage regulators for excitation control of a synchronou s generator. Practical aspects such as controller robustness and proce ssing power are discussed Conventional microprocessor technology is un able to achieve the sampling periods required for industrial applicati on. A parallel architecture using INMOS transputers combined with an a dvanced VME bus-based measurement system provide an open-ended solutio n to this problem, and enable the adaptive controllers to operate with in the required 10 ms sample period. The scheme was initially evaluate d on a computer simulation of a three-phase turboalternator. A laborat ory model turbogenerator was then controlled to test the performance a nd reliability of the system under realistic conditions.
