Abstract

SISTEMA GERADOR DE ENERGIA ELéTRICA COM PROCESSAMENTO INTELIGENTE DE SINAIS DE POSICIONAMENTO E TURBINA EóLICA. Provido de melhor eficiência energética devido a uma sensibilidade reduzida a erros, na detecção do posicionamento angular do rotor. O sistema inclui um gerador de energia elétrica com um rotor e um codificador de posicionamento conectado para detectar o posicionamento angular do rotor e gerar um sinal de posicionamento correspondente. Um processador recebe o sinal de posicionamento, calcula um posicionamento angular em resposta, calcula um posicionamento angular estimado com base nos sinais de posicionamento recebidos anteriormente e, finalmente, gera um posicionamento angular processado com base no posicionamento angular calculado e no posicionamento angular estimado. Este posicionamento angular processado é uma medição mais confiável do posicionamento do rotor, pois ele é baseado nos sinais de saida anteriores de posicionamento, de preferência, em vários sinais de entrada anteriores. Isto proporciona uma alta imunidade a erros de curto prazo no sinal de posicionamento, e, por exemplo, para turbinas eólicas, isto significa que a operação normal pode ser mantida em situações em que o codificador de posicionamento falhe temporariamente, e em caso de falha total, a operação pode ser mantida durante um periodo suficiente para evitar o desligamento de emergência. Em modalidades preferidas da presente invenção, o processador é projetado para pré-filtrar o sinal de posicionamento, ou seja. detectar e corrigir antes de calcular o posicionamento angular. De preferéncia, também inclui o manuseio de erros com base na comparação do posicionamento angular estimado com o posicionamento angular calculado e, assim, determina um sinal de entrada para uma malha de sincronismo de fase, com base no estimador, que também é utilizado para fornecer o posicionamento angular processado..ELECTRIC POWER GENERATING SYSTEM WITH INTELLIGENT PROCESSING OF POSITIONING SIGNS AND WIND TURBINE. Provided with better energy efficiency due to reduced error sensitivity in detecting rotor angular position. The system includes an electric generator with a rotor and a positioning encoder connected to detect the angular positioning of the rotor and generate a corresponding positioning signal. A processor receives the positioning signal, calculates an angular positioning in response, calculates an estimated angular positioning based on previously received positioning signals, and finally generates a processed angular positioning based on calculated angular positioning and estimated angular positioning. This processed angular positioning is a more reliable measurement of rotor positioning as it is based on the previous positioning output signals, preferably on several previous input signals. This provides high immunity to short-term positioning signal errors, and, for example, for wind turbines, this means that normal operation can be maintained in situations where the positioning encoder temporarily fails, and in case of total failure. , operation can be maintained for a sufficient period to prevent emergency shutdown. In preferred embodiments of the present invention, the processor is designed to pre-filter the positioning signal, that is. detect and correct before calculating angular positioning. Preferably, it also includes error handling based on comparing the estimated angular positioning with the calculated angular positioning and thus determines an input signal to an estimator based phase synchronization loop which is also used to provide the processed angular positioning ..
