摘要: 波浪能发电装置下海部署前评估其发电系统性能对装置的研发至关重要。目前评估方式主要有计算机仿真和实验室水池试验或者海试。计算机仿真依赖于精确的数学模型,实验室水池测试和海试耗资大,且小模型物理试验有时难以准确反映原型的实际情况。为了解决这一问题,研究一套能模拟波浪作用的半物理仿真试验平台,通过在仿真回路中接入真实的发电系统,并设计一套液压驱动系统实时复现波浪作用下浮子的运动,无需实验室水池或者海试便可实现装置下海部署前对其发电系统性能进行测试。为验证半物理仿真试验方案的可行性,以中国典型海况为例,以筏式波浪能发电装置为研究对象,设计制造出半物理仿真试验平台。在此基础上,研究液压驱动系统的跟踪性能和发电系统的性能。结果表明,所设计的液压驱动系统能很好地复现波浪作用下两筏体间的相对纵摇运动,半物理仿真试验平台的测试结果能较好地反映发电系统的性能。研究成果为模拟波浪能发电和评估其发电系统性能提供一种相对廉价又有效的试验方式。

Abstract: Assessing the performance of the power generation system of a wave power generation device accurately before being deployed is important for its development. Two ways to achieve this aim are computer simulation and wave tank test or open sea test. Computer simulation deeply relies on the accuracy of the mathematical model, while wave tank test or open sea test costs largely, and the test results obtained by using a small-scale model sometimes cannot represent those of the prototype. To tackle this problem, a hardware-in-the-loop (HIL) simulation platform that can replicate the action of waves is studied. The real power generation system is inserted in the simulation loop, and a hydraulic power pack system is used to reproduce the wave-induced motion of the rafts. Thus, the performance of the power generation system can be assessed before the device being deployed in the absence of wave tank or open sea environment. To verify the feasibility of the HIL scheme, a HIL simulation test rig is designed and manufactured for the raft-type wave power generation device based on China Sea states. On this basis, the tracking ability of the hydraulic power pack system and the performance of the power generation system are studied. Results show that the hydraulic power pack system can replicate the wave-induced relative pitch motion of the rafts, and the test results obtained in the HIL simulation test rig can reflect the performance of the power generation system. It is found to offer a reasonably realistic and relatively inexpensive approach to simulate wave power generation and assess the performance of its power generation system.
