Abstract

?aparelho e método para assegurar confiabilidade de disparo de proteção de subestação inteligente?, por tratar-se a presente invenção de um aparelho e método para assegurar a confiabilidade de um disparo de proteção de uma subestação inteligente. o aparelho compreende uma cpu principal e uma cpu auxiliar conectadas juntas, e um fpga principal e um fpga auxiliar conectados juntos, em que tanto o fpga principal como o fpga auxiliar são conectados a uma camada física de um aparelho de proteção, e tanto a cpu principal como a cpu auxiliar são conectadas a uma extremidade de saída de dados de monitoramento de um dispositivo protegido. o método compreende: a cpu principal que envia um resultado de processamento para o fpga principal, a cpu auxiliar que envia o resultado de processamento para o fpga auxiliar, e o fpga auxiliar que sincroniza informações atuais com o fpga principal após o recebimento de informações enviadas pela cpu auxiliar; e quando o fpga principal recebe informações de disparo, o fpga principal compara a consistência de informações de disparo atuais obtidas a partir da cpu principal com aquela de informações de disparo atuais obtidas a partir do fpga auxiliar, e se as duas forem consistentes, o fpga principal envia as informações recebidas a partir da cpu principal para o aparelho de proteção, de outro modo, descarta as informações recebidas a partir da cpu principal. de acordo com a presente invenção, uma habilidade antifalha de operação de um aparelho de proteção é aperfeiçoada, e é assegurado que o aparelho não pode causar um movimento falso de um dispositivo primário devido a um erro desconhecido em que um dispositivo de hardware, perturbações de evento único (seu), etc. falha.
