摘要

为提高液压式波浪能发电装置（WEC）的运行效率,提出一种多级储能液压式动力输出（PTO）系统,通过蓄能器与储能飞轮实现多级储能。在AMESim中建立液压PTO仿真模型,研究储能元件对系统响应的影响,并分析不同海况下的发电过程,同时构建额定功率为100 W的缩尺液压PTO样机进行性能试验。研究表明,在中低海况下,液压能到电能的平均转换效率可达89%,较未引入多级储能技术提升6%;高海况触发能量溢流时,仍可达到5 kW额定发电目标。缩尺样机发电效率可达到45.6%,能接近额定100 W的发电要求。

Abstract

In order to improve the operating efficiency of hydraulic wave energy converters （WECs）, this paper proposes a multistage energy storage hydraulic PTO system, which achieves multistage energy storage through accumulators and energy storage flywheels. A hydraulic PTO simulation model is established in AMESim to study the impact of energy storage components on system response and analyze the power generation process under different sea conditions. Meanwhile, a scaled hydraulic PTO prototype with a rated power of 100 W is built for performance testing. The study shows that, under medium and low sea conditions, the average conversion efficiency from hydraulic energy to electrical energy reaches 89%, which is 6% higher than the system without the multistage energy storage technology. Under high sea conditions, when energy overflow is triggered, the system can still achieve the 5 kW rated power generation target. The scaled-down prototype's power generation efficiency can reach 45.6%, which is close to the rated 100 W power generation requirement. The simulation and testing methods used in this study can also be extended to other wave energy converter hydraulic PTO systems, providing a basis for parameter optimization and performance improvement of wave energy devices under different sea conditions.
