| 摘 要： | 针对目前国内外柔性直流换流系统电磁兼容的研究工作较少且主要集中于仿真研究方面的现状,其理论研究的可信度与正确性缺乏相应的实验数据进行验证。国内仅有一条柔性直流输电示范工程,系统停运复杂,文中采用华北电力大学新能源实验室VSC-HVDC换流系统的实验平台,分析了VSC-HVDC换流系统的结构,介绍了本次电磁场测试工作的概况,采用环形天线在实验室典型位置对换流系统正常运行时150 k Hz~30MHz的频率范围内的室内空间电磁场环境进行了点频测量与扫频测量,测量分析指出换流系统所产生的辐射电磁干扰随频率的增加衰减很快,在3 MHz时换流系统有最明显的辐射电磁干扰,频率25 MHz时电磁干扰有增大的趋势。

| Abstract: | Recently, researches about electromagnetic compatibility of VSC-HVDC converter system are rarely ad-dressed in published works at home and abroad , and they mainly focus on simulation research .The theoretical study is lack of appropriate experimental data to validate the reliability and validity .There is only one VSC-HVDC demonstra-tion project in China , and the system outage is complex .This paper analyzes the architecture of VSC-HVDC converter system , and presents an overview of the work of this electromagnetic field test , which is based on the VSC-HVDC ex-perimental platform of New Energy Laboratory in NCEPU .The electromagnetic field of interior laboratory is measured by both point frequency and sweep measurements , by means of loop antenna placed in the typical positions , when the frequency range of proper functioning of converter system is the 150 kHz~30 MHz.It is indicated that with the fre-quency increasing , the electromagnetic disturbance level quickly decreases , radiated electromagnetic interference of converter system is the most obvious at 3 MHz, and the interference has an increasing trend when frequency is greater than 25 MHz. |
