dc.description.abstract | Excitation Boosters (EB) are aimed at improving Fault Ride Through (FRT) capability of synchronous generators equipped with bus fed static excitation systems by means of adding a supplementary voltage or current source to the rectifier. Alstom patented a voltage EB, whose main component is an ultracapacitor that is connected to the field winding in case of a fault by an onoff controller. The ultracapacitor is sized in such a way that the FRT capability is improved when the generator is connected to an infinite bus. However, the paper shows that EBs governed by on-off controllers may result in adverse effects in case of remote faults from generators that may occur in multi-machine systems. To sort this problem out, a controller that modulates the EB voltage using the generator speed deviation with respect to the speed of the Center Of Inertia (COI). The speed of the COI is obtained using a Wide Area Measuring System (WAMS). | en-GB |
