海洋波浪也是清洁能源:我国波浪发电装置成功突破关键技术

2017-07-10 14:59:54   新华社

新华社北京7月10日电(记者胡喆)海洋波浪蕴藏着巨大的能量,如何有效地利用这一清洁能源?记者10日从中国电子科技集团公司获悉,中国电科38所最新研制的波浪发电装置正式通过国家海洋局验收。该装置成功突破波浪能液压转换与控制装置模块及千伏级动力逆变器关键技术,实现波浪稳定发电,且在小于0.5米浪高的波况下仍能频繁蓄能。这一关键技术的突破,为我国波浪发电工程化应用奠定了基础。

我国拥有绵长的海岸线,汹涌起伏的海浪蕴藏着无尽的能量。为利用好这一天然能源“发动机”,中国电科38所在海南岛进行海浪发电试验,历经3年技术攻坚,项目组通过不断优化和改进装置模型,采用智能侦调综合控制技术,提升了波能装置的转换效率,增强了吸能效果;首创的宽幅逆变稳定技术,实现了海洋能千伏级逆变系统的高效转换。近三个月的海上试验表明,该发电装置浮体摆动正常、吸波稳定,飞轮蓄能均匀而连续,发电性能稳定。

该项目组负责人王振收介绍,他们研制的岸崖浮摆式浪能发电装置,由浮子、摆杆、压载框、液压系统、飞轮系统、逆变器、控制及监控系统等组成,其浮子既可以像船舶一样漂浮,也可以在台风来临时收拢到岸边。目前,这款波浪发电装置前期装机5千瓦,采用浮体重构模块化设计理念,后续可以扩大波浪能发电系统装机容量,通过并网可以提供标准电力供给。
