Abstract

é descrito um método de aviso rápido para falhas em válvulas conversoras. o método compreende: dentro de um período de tempo previamente determinado, registro de informações de tempo de sinais de indicação de estado retroalimentados por unidades de controle de tiristores (tcu) de válvulas conversoras, realização de estatísticas e comparação das informações de tempo utilizando um método de estatísticas de viés, marcação de nível de tiristor cujo viés excede um valor previamente determinado e determinação da probabilidade de falhas no tiristor de acordo com o resultado da marcação. também é descrito um sistema de aviso rápido para falhas em válvulas conversoras. o sistema compreende um conjunto de registro utilizado para armazenar dados de viés de níveis de tiristor de uma válvula conversora e um processador em alta velocidade empregado para processar, utilizando um método de estatísticas de viés, sinais de indicação de estado retroalimentados por tcus. a solução de acordo com a presente invenção pode identificar um nível de tiristor com probabilidade de falha relativamente alta, atingir aviso rápido e fornecer referência para a substituição de dispositivos, de forma a reduzir a probabilidade de interrupção de sistemas de corrente direta devido a falhas de nível de tiristor, além de fornecer referências para a otimização de desempenho do dispositivo e otimização do projeto de circuito de válvulas conversoras.
