摘　　要：比较各种波能转换装置优缺点,并对振荡水柱式发电装置并网运行进行建模.当波浪发电系统并网时,采用TCSC对系统进行无功控制并提高电压稳定性.在正常运行和线路发生故障2种情况下,分别分析TCSC对波浪发电系统的影响.研究结果表明,TCSC所表现的补偿线路阻抗的能力在稳定电压、抑制系统振荡等方面有较好的作用;采用TCSC后的系统静态输送功率极限和暂态稳定性都得到了较大提高.Various kinds of wave energy conversion devices are compared. A model of the Oscillation Water Column wave power device is established. Then the TCSC is used to control the system＇s reactive power so as to improve the voltage stability in grid-connection mode. The influences of TCSC on the wave power system are respectively analyzed under normal and fault conditions. The results show that TCSC can successfully stabilize the voltage and suppress system oscillation with good compensation for the line impedance. Also, the limit of static conveying power and transient stability have been improved greatly by using the TCSC system.
