摘要

The filter capacitor installation is one of main noise sources in converter station.In this paper, the parallel capaci-tor providing by the company is taken as the research object to present a simulation method of vibration and noise of capacitor based on ANSYS and LMS.Virtual lab.First of all, mechanism of vibration and noise of capacitor are analyzed to get the boundary conditions of the finite element model of vibration and noise.Second, the simulation of vibration and noise of capaci-tor are made by ANSYS and LMS Virtual lab.Finally, a noise experiment test of the capacitor is made, and the simulation re-sult is compared with measuring values.Thus the accuracy of the simulation method of vibration and noise of capacitor is veri-fied.%电容器装置是换流站中噪声的主要来源之一。结合某公司提供的并联式电容器，提出基于ANSYS与LMS Virtual．lab的电容器振动与噪声仿真方法。分析电容器振动与噪声产生机理，得到电容器振动与噪声有限元模型的边界条件；分别运用ANSYS与LMS Virtual．lab进行电容器振动与噪声仿真；最后，对电容器进行噪声测试实验，并将仿真结果与实测值进行对比，验证了上述方法的准确性。
