【摘要】：为解决波浪能发电过程中把不稳定的波浪能转换为稳定的电能的问题,本文设计了一种间歇性波浪能液压蓄能发电系统,并且提出了基于实验测试的平稳发电实时控制策略。对负载对液压系统工作压力影响、液压马达压差与比例流量阀开口度的关系进行了理论分析。在理论的基础上,通过LabVIEW数据采集得出了压差、比例阀开口度、马达输入流量的实验数据,通过对实验分析,建立了保证流量稳定的比例阀开口度控制曲线。实验结果表明,该系统在蓄能器的稳压缓冲和控制系统的调节作用下,可以保证发电机功率和发电电压稳定,从而实现稳定发电的目的。
[Abstract]:In order to solve the problem of converting unstable wave energy into stable electric energy in the process of wave energy generation, an intermittent wave energy hydraulic storage power generation system is designed in this paper. A real-time control strategy of steady power generation based on experimental test is proposed. The influence of load on the working pressure of hydraulic system and the relationship between hydraulic motor pressure difference and the opening degree of proportional flow valve are analyzed theoretically. On the basis of the theory, the relationship between the pressure difference of hydraulic motor and the opening degree of proportional flow valve is analyzed theoretically. The experimental data of pressure difference, proportional valve opening degree and motor input flow rate are obtained by LabVIEW data collection. Through experimental analysis, the control curve of proportional valve opening degree to ensure steady flow rate is established. The experimental results show that, The system can ensure the generator power and voltage stability under the action of the accumulator voltage buffer and the control system, so as to achieve the purpose of stable power generation.
