Disclosed are a wave power generation system for generating power by means of a hydraulic circuit, and a method for controlling same. The wave power generation system comprises: a tension transmission member for transmitting motion energy which is generated by means of six-degrees-of-freedom motion of a movable object floating on the waves; a power conversion unit comprising a fluid pressure generation unit which is connected to the tension transmission member and is for generating a fluid pressure; and an equalizer connected to the tension transmission member and for maintaining the tension of the tension transmission member. In the power conversion unit, if tension is applied from the tension transmission member, the fluid pressure generation unit enables a fluid to flow in a first direction by means of the tension and, if tension is not applied from the tension transmission member, the fluid pressure generation unit enables a fluid to flow in a second direction by means of the equalizer. L'invention concerne un système de production d'énergie houlomotrice pour produire de l'énergie au moyen d'un circuit hydraulique, et son procédé de commande. Le système de production d'énergie houlomotrice comprend : un élément de transmission de tension pour transmettre une énergie de mouvement qui est générée au moyen d'un mouvement à six degrés de liberté d'un objet mobile flottant sur les vagues; une unité de conversion de puissance comprenant une unité de génération de pression de fluide qui est reliée à l'élément de transmission de tension et qui est destinée à générer une pression de fluide; et un égaliseur relié à l'élément de transmission de tension et destiné à maintenir la tension de l'élément de transmission de tension. Dans l'unité de conversion de puissance, si une tension est appliquée à partir de l'élément de transmission de tension, l'unité de génération de pression de fluide permet à un fluide de s'écouler dans une première direction au moyen de la tension et, si une tension n'est pas appliquée à partir de l'élément de transmission de tension, l'unité de génération de pression de fluide permet à un fluide de s'écouler dans une seconde direction au moyen de l'égaliseur. 유압 회로에 의해서 전력을 생산하는 파력발전 시스템 및 제어 방법이 개시된다. 파력발전 시스템은, 파도에 부유하는 가동물체의 6자유도 운동에 의해 발생되는 운동 에너지를 전달하는 장력전달 부재, 상기 장력전달 부재에 연결되어 유압을 발생시키는 유압 발생부를 포함하는 동력변환부 및 상기 장력전달 부재에 연결되어 상기 장력전달 부재의 장력을 유지하는 이퀄라이저를 포함한다. 여기서, 상기 동력변환부는, 상기 장력전달 부재에서 장력이 인가되면, 상기 장력에 의해서 상기 유압 발생부가 제1 방향으로 유체를 유동시키고, 상기 장력전달 부재에서 장력이 인가되지 않으면, 상기 이퀄라이저에 의해서 상기 유압 발생부가 제2 방향으로 유체를 유동시킨다.
