摘要
在海洋能发电装置中采用基于液压传动的蓄能稳压方式可以较好地实现能量的最大捕获和输出功率稳定。实现这一功能的系统主要由能量输入系统、液压系统、发电系统和自动控制系统等组成。文中首先对系统进行数学建模及计算机仿真,然后在半物理仿真试验台基础上,对各种工况进行了仿真研究。计算机和半物理仿真试验台的仿真结果表明,该系统可以实现海流能发电装置的变速恒频控制,从而实现能量的最大捕获和输出功率稳定。
The maximum energy capture and the stability of output power of marine current turbine can be achieved by storage methods based on hydraulic transmission system, which consists of an energy input system, a hydraulic pressure system, a generation system and a control system. A mathematical model of the system is established and computer simulation is done according to the model. Various working conditions are simulated on a semi-physical simulation platform. The computer and physical simulation results show that the variable speed constant frequency control of marine current turbine can be achieved, to maximize energy capture and stabilize power outputs.
