摘　　要：针对自治控制模式下液压蓄能式波能装置多液压发电机组在启动或停止时输出功率脉动问题,提出一种基于有功功率补偿的波浪能平均功率送出方法。根据波浪能转换发电系统特点及工作原理,在并网逆变器交流侧挂一台有功功率补偿装置,能同时平抑多台液压发电机组的功率脉动,并以平均功率送出。为验证该方法的有效性,建立多液压发电机组并网功率脉动平抑仿真模型。仿真结果表明,经功率补偿后波能装置并网功率平缓变化,多发液压发电机组的启动或停止时的功率脉动能被完全吸收,平均功率送出方法可提高大功率波能装置在海岛微电网等场合的适应性。In order to solve the problem of output power pulsation of multiple hydraulic generators in hydraulic storage wave energy converter under autonomous control mode,a method of average power for transferring wave energy based on an active power compensation is proposed.According to the characteristics and working principle of the power generation system of the wave energy converter,an active power compensation device is attached to the AC side of the grid-connected inverter,which can simultaneously suppress the power pulsation of multiple hydraulic generator sets and transfer the average power to the grid.A simulation model for power pulsation suppression of grid-connected hydraulic generator sets is established to verify the effectiveness of this method.The simulation results show that the grid-connected power of the wave energy converter changes gently attached the power compensation,and the power pulsation caused during the starting or stopping of multiple hydraulic generator sets can be completely absorbed.The method of average power transferring can improve the adaptability of the high-power wave energy converter in the island micro-grid and other situations.
