Abstract
The direct current from the excitation system sustains the stator and rotor magnetically coupled with spawning reactive power in the generator. Though, any excitation system failure grades to generator loss of excitation and suspend power transmission from the generating unit to the grid. This paper presents a new excitation loss protection scheme based on the study of field voltage, quadrature axis voltage, and reactive power under specified system voltage. The proposed algorithm limits the reactive power consumption of the faulted generator to the ability of the system to feed the faulted generator without system loss of stability. In this paper, the IEEE-9 bus system is used to study the proposed approach to various excitation loss events. And the results showed that the new algorithm not only overwhelmed the mal-operation of the excitation loss relay but also detects all possible excitation failures without system collapse in a short time.
