Abstract: Kirchhoff formula method is employed to predict the surrounding fence noise level of the filter capacitor installation in the converter station. The computation results are compared with those by the monopole array sound source method, and by the measurement in Zaoqing. It is found that our computation results agree with the measurement data very well. Thus, this method is proved reasonable and correct.

Key words: filter capacitor installation, monopole array sound source, Kirchhoff formula

摘要： 引入Kirchhoff公式，对于换流站中滤波电容器装置围栏外噪声水平进行预估，并将该方法的计算结果与单极子阵列声源计算方法的计算结果、肇庆实际测量结果进行了比较。结果表明，实测结果与Kirchhoff公式计算结果具有良好的一致性，进而验证了该方法的合理性和准确性。
