由于真实的波浪输入功率是连续的、周期性的变化，如何在波浪能利用过程中稳定运行和发电，已成为一个不可避免的重要课题。本文以摆锤式液压取力器（HPTO）的转换器为研究对象，通过仿真和实验研究了其关键部件--高压蓄能器、油箱和流量控制阀对HPTO工作稳定性的影响。wave.energy对高压蓄能器的参数进行了分析和优化。本文还研究了带油箱和不带油箱的HPTO的动态性能。此外，还给出了流量调节阀在输入功率过大和切负荷时的作用。结果表明，关键部件对HPTO的运行稳定性起着至关重要的作用。高压蓄能器和油箱的合理配置对提高输出功率质量和稳定性具有重要意义。流量控制阀的适当动作有利于保护和稳定。因此，在设计HPTO时应优先考虑这些关键部件。
Since the input power of the real waves varies continuously and periodically, how to stabilise the operation and.generation during wave energy utilisation has become an inevitable and significant topic. This study focuses on the wave.energy converter of a hydraulic power take-off (HPTO) connected to a pendulum and studies the influences of the key.components, i.e. the high-pressure accumulator, oil tank and flow control valve, on the operational stability of HPTO by.simulations and experiments. Parameters of the high-pressure accumulator are analysed and optimised. The dynamic.performance of the HPTO with or without the oil tank is also investigated. Besides, the functions of the flow control valve in the.cases of excessive input power and load shedding are given. Results show that the key components play very important roles in.the operational stability of HPTO. Reasonable configurations of the high-pressure accumulator and oil tank are significant to.improve the quality of output power and stability. Appropriate actions of the flow control valve are beneficial to protection and.stability. Therefore, these key components should be considered preferentially during the design of HPTO.
