Abstract

Patente de Invenção: "USINA GERADORA EóLICA". Uma usina geradora eólica onde o eixo motriz comunica-se com um gerador síncrono (3) opcionalmente através de uma engrenagem (2) e com um transformador, caso houver, comunicante através de um inversor CA/CC (7) com um cabo de transmissão de alta tensão de corrente contínua (9). O gerador síncrono (3) é conectado com um controlador de campo magnético (4). Em resposta a um parâmetro de saída, tal como a potência gerada pelo gerador síncrono (3), este controlador de campo magnético (4) é adaptado para variar o campo magnético no gerador (3) em resposta ao parâmetro de saída mencionado. Conseq³entemente, é possível compensar uma possível variação no parâmetro de saída, por intermédio da qual o parâmetro de saída é estabilizado. Como resultado é possível compensar uma velocidade variável de rotação.
