The brushless excitation system
Electrical Engineering, 1960A NEW TYPE of excitation system has been developed for use in the electric utility industry in which the generator collector and collector brushes, and the exciter commutator and commutator brushes are eliminated. The basic difference between this system and its predecessors is an a-c exciter mounted on the same shaft as the generator field.

COORDINATION OF THE EXCITATION SYSTEMS IN A MULTIMACHINE POWER SYSTEM
IFAC Proceedings Volumes, 1983Abstract Each generator in a power system is equipped with an Excitation Control System. Incorrect selection of the parameters of such systems might result in prolonged oscillations among the rotors of the generators. This problem can be overcome with a systematic selection of excitation system parameters so as to achieve optimum damping of all the ...

System With Excitation Control
International Journal of MC Square Scientific Research, 2011Two ad-hoc, power allocation strategies for a decentralized distributed Space Time Block Coding (Dis-STBC) system is proposed in this paper where knowledge about the Channel State Information (CSI) is not available at the transmitter. The first is an open-loop strategy which requires no control signaling; the second is a feedback-assisted strategy ...

Excitation system for a synchrotron
Electrical Engineering, 1951THE EXCITATION of a 70 mega-electron volt synchrotron magnet involves single-phase supply of loss energy to a tuned circuit, usually resonant at 60 cycles, wherein approximately 3,000 kva are circulating. This resonant circuit has a X L /R ratio or Q of approximately 100, thus the frequency sensitivity of the circuit is quite great, and it usually is ...

Response of a parametrically-excited system to a nonstationary excitation
2014The response of a parametrically-excited system to a deterministic nonstationary excitation is studied. The system, which has a cubic nonlinearity, has one focus and two saddle points and can be used as a simple model of a ship in the head or follower seas.

Constructing a dynamic equivalent for a power system involves several steps: the partition of the system into coherent areas, the aggregation of coherent generator buses, and the aggregation of the coherent generators and their control devices. These steps have been discussed in previous chapters, including a method in Chap.
