A falha de comutação em sistemas HVDC (High Voltage Diret Current - Corrente contínua de alta tensão) é um problema crítico que ocorre quando a corrente não é transferida entre os tiristores durante o funcionamento do inversor, podendo levar à instabilidade do sistema, a danos no equipamento ou mesmo à paragem do sistema. Este problema surge devido a factores como flutuações de tensão, mau controlo da corrente ou alterações súbitas nos parâmetros do sistema.A abordagem SL2CC (Selective Load Commutation Control) é um método avançado para mitigar a falha de comutação em sistemas HVDC. Foi especificamente concebida para evitar a ocorrência de falhas de comutação, controlando seletivamente a carga do inversor e assegurando que as formas de onda da tensão e da corrente permanecem estáveis em condições operacionais variáveis. O conceito central do SL2CC envolve o ajuste dos sinais de controlo em tempo real para garantir transições suaves entre os tiristores durante o processo de comutação.
