Highly Reliable Intelligent Control Strategy of a Industrial Microcomputer-base d Excitation Regulator for Large Synchronous Electric Generator

To meet the requirement on the excitation regulation of the huge hydro electric generator of future Three Gorges Hydro Power Plarft,a highly reliable intellige nt i ndustrial microcomputer-based excitation regulator has been successfully develo ped highly reliable intelligent control strategy is applied:when all the compone nts of the regulator are proper,the control parameters are tuned in real time an d on l ine to adapt the characteristics and the operation states of the unit optimal pe r formance will be achioved.In case fauit(s) reside in the regulator (such as the outage of the sensor(s) or the actuator(s),mis-operation(s) of the operator,etc .),the control parameter(s)will be replaced or the control structure will be reconfi-gured to ensure the stable and safe operation of the unit.
