摘要: 基于共振式波力发电装置的工作原理及特点,结合液压传动在能量提取方面的突出优势,设计出该发电装置的液压提能系统。建立该系统的数学模型,并基于AMESim进行计算机仿真,通过补油分析、蓄能器和比例调速阀的仿真试验为系统的性能优化和能量控制提供理论依据。在实验室环境下建立液压提能系统试验平台,通过蓄能稳压和提能试验验证了理论分析和仿真结果的可靠性。仿真和试验结果表明,设置补油可以明显提高液压提能系统的运行稳定性和输出功率;合理配置蓄能器可以改善系统运行时压力和流量波动;比例调速阀可以调节并稳定流量,进而调节输出功率。通过以上措施,可以保证系统具有发电平稳连续、功率调整迅速、过渡过程时间短等良好的动、稳态特性。

Abstract: Based on the working principle and characteristics of resonant wave generation device, the power take-off system is designed combined with the prominent advantages of hydraulic transmission in power extraction. The mathematical model of power take-off system is established, and the computer simulation is carried out by AMESim. Through the simulation test of oil supply, accumulator and proportional flow control valve, the theoretical basis for the performance optimization and power control of the system is provided. In the laboratory environment, the test platform of power take-off system is established. The reliability of the theoretical analysis and simulation results are verified by the experimental results of pressure-maintaining storage test and extraction power test. The simulation and experimental results show that oil supply can significantly improve the stability and increase the output power, and rational allocation of accumulator can effectively reduce the fluctuation of pressure and flow, and proportional flow control valve can adjust and stabilize the flow and then adjust the output power. The measures above can ensure the good dynamic and steady state characteristics which make it possible to generate steady and continuously, adjust the power quickly, shorten the transient process.
