Abstract
SISTEMA DE COMPENSAÇÃO PARA UM ROTOR. A presente invenção refere-se ao sistema de compensação desta invenção que é adaptado para modificar o sinal de ângulo de passo de pá de rotor recebido de um controlador centralizado e emitir um sinal de ângulo de passo de pá de rotor compensado para o atuador para cada pá independentemente a fim de neutralizar as cargas sobre a pá causadas pela não uniformidade do campo de vento, com o benefício de reduzir as cargas assimétricas do rotor. O sistema de compensação individual para cada ângulo de passo da pá de rotor não depende nem das medições de carga para qualquer outra pá nem do ângulo de passo compensado da pá de rotor para qualquer outra pá senão através do sinal de ângulo de passo de pá de rotor coletivo pelo controlador centralizado. O sistema de compensação desta invenção é, portanto, um sistema reativo que grandemente aumenta a vida útil da instalação.
