Exciter Control Module
Exciter Control Module Exciter Control Module
Overvoltage Limiter• Protects the machine from sustained highterminal voltage levels• Automatic phase back signal provided after• Automatic phase back signal provided aftera fixed time delay
Under Excitation Limiters• Two separate limiters– Minimum Excitation Limiter (MEL) utilizesfive-segment piecewise linear curverepresenting steady state stability limit– Under Excitation Limiter (UEL) coordinateswith non-circular generator capability curve• Dynamic adjustment of pickup based uponhydrogen pressure and cooling airtemperature
