摘要

为实现对波浪的快速响应和波浪能的高效收集利用

以波浪能发电装置液压式能量转换系统为出发点

开展多级机组能量转换系统的方案设计

确定各个元气件的设计参数。为验证多级机组能量转换系统的工作性能

开展3种海况下的装机总功率均为100 kW的单级能量转换系统、2级机组能量转换系统（50 kW+50 kW）、3级机组能量转换系统（20 kW+30 kW+50 kW）的仿真计算

并针对仿真结果中的系统压强、发电总功率、各发电机功率进行对比分析。结果显示

小浪况下3级机组发电量最小

2级机组发电量最大;大浪况下

3级机组发电量最大

2级机组发电量最小。总之

同样的浪况下

多级机组能量转换系统对波浪的响应时间、发电电量均优于单极机组

且随着机组级数越多

系统对大浪的适应性越高。

Abstract

In order to achieve a rapid response to waves and the efficient collection and utilization of wave energy

starting from the hydraulic power take-off（PTO）system of the wave energy converters

the scheme design of the multi-stage unit PTO system was carried out

and the design parameters of each component were determined. To verify the performance of the multi-stage unit PTO system

simulations were conducted under three sea conditions for a single-stage PTO system

a two-stage unit PTO system （50 kW+50 kW）

and a three-stage unit PTO system（20 kW+30 kW+50 kW）

all with a total installed power of 100 kW. The system pressure

total power generation

and the power of each generator from the simulation results were compared and analyzed. The results show that under small wave conditions

the three-stage unit generates the least amount of electricity

while the two-stage unit generates the most electricity; under large wave conditions

the three-stage unit generates the most electricity

and the two-stage unit generates the least. In summary

under the same wave conditions

the multi-stage unit energy conversion system has a better response time and generates more electricity than the single-stage unit; and the more stages a unit has

the higher the system's adaptability to large waves will be.
