Abstract

Patente de Invenção:<B>"MECANISMO DE DISTRIBUIçãO ELéTRICO COM UM SISTEMA DE CONTROLE DE SINCRONIA E UM ATUADOR".<D>Em um sistema de distribuição de potência, a sincronização de operações de mudança com uma forma de onda de voltagem ou de corrente CA pode ser realizada mais percisamente com um projeto de controle de movimento baseado em microprocessador com retroalimentação de laço fechado. Pelo emprego de um projeto de controle de movimento baseado em microprocessador com retroalimentação de laço fechado, a posição e a velocidade de um contato de mecanismo de distribuição podem ser monitoradas e otimizadas em tempo real durante uma operação de mudança, desse modo assegurando-se uma operação de mudança mais precisa. Mais ainda, o projeto de retroalimentação de laço fechado intrisecamente compensa efeitos de coisas tais como temperaturas ambiente, flutuações de forma de onda CA, e mudanças na condição física do mecanismo de distribuição. O projeto de retroalimentação de posição de laço fechado também é capaz de otimizar vários parâmetros de função de transferência associados ao processo de retroalimentação de laço fechado, durante e subseq³ente a uma operação de mudança, para assegurar adicionalmente que as operações de mudança sejam mais precisamente sicronizadas com as formas de onda de voltagem ou de corrente Ca.
