Rw. Pretorius et al., A neural-network-based controller for the cost-effective operation of a hybrid compensator for nonactive power, IEEE IND E, 47(6), 2000, pp. 1220-1227
The need to eliminate distortion from power networks has led to the develop
ment of various compensator topologies. The increasing cost of electrical e
nergy requires the choice of the most cost-effective compensator operation,
An investigation of a neural-network-based controller that chooses the mos
t cost-effective compensator mode of operation on the basis of a continuous
analysis of load conditions and the operational losses of the elements in
the compensator structure are reported. The modeling of operational losses
of each subtopology and the required control strategy are discussed. The re
sults show that the operational loss savings due to the neural-network-cont
rolled hybrid compensator were 30%-70% as compared to the conventionally co
ntrolled hybrid compensator, while also conforming to other control strateg
y requirements.
