摘    要:在波力电站中采用蓄能稳压方式把不稳定波浪能输入转换为稳定的能量输出是一种新的设想,实现这一设想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,然后在实物模型基础上,采用变频器驱动电动机方式模拟海洋波浪能的不稳定输入,系统控制方式采用增量式PID算法。计算机和物理模型仿真的结果表明,该系统实现了把不稳定的能量输入转换为稳定的电能输出,其系统的设计思想可直接应用于真实系统的设计。

关 键 词:波浪能  仿真  蓄能稳压系统  自动控制

Abstract:Adopting a pressure-maintaining storage system in a wave power station is a new idea for converting the unsteady ocean wave energy input into the steady power output, According to the idea, the implemented system consists of an energy input system, a hydraulic pressure system, a generating system and a control system. In this paper, a mathematical model of the system is established and the computer simulation is done according to the mathematical model. Based on the physical mode, the unsteady wave energy input is simulated by the way of the motor driven by a transducer and the differential PID control algorithm is applied to the control system, The computer and physical mode simulation results show that the system can convert the unsteady energy input into the steady electric energy output. The idea is feasible and valuable for the design of actual systems.
Keywords:wave energy  simulation  pressure-maintaining storage system  automatic control
