Influência da inserção do dispositivo STATCOM na proteção contra perda de excitação de geradores: Uma contribuição utilizando a lógica fuzzy

Brazil is a country with continental dimensions and has power generation system interconnected all regions, through transmission lines (TLs), allowing supply for its all-consumption centers. However, building new TLs may be unfeasible in an environmental financial sense. With the advancement of electronics, FACTS (Flexible Alternating Current Transmission Systems) devices were created, which are based on series or parallel reactive compensation network, flexibility operation, lower losses better stability. insertion such cause maloperation synchronous generators protection. In this sense, work presents effects inserting one model (STATCOM - Static Synchronous Compensator), relation to protection against loss excitation generators. To identify improve response excitation, it proposed use fuzzy classifier, effectiveness compared traditional scheme that uses impedance characteristic.
