| 摘 要： | 基于矩最法，提出了一种适合于变电站内开关操作时母线、设备间连线、架空线路产生的电磁场的计算方法，可以应用于变电站内较高频率分量的电磁场计算。应用文中计算方法与给出的计算方法分别对同一算例进行计算，其计算结果均一致，验证了文中方法的有效性。最后，借助于快速傅立叶变换，应用文中计算方法对某500kV变电站开关合闸操作时空载母线上的电流波过程和空间瞬态电场分布进行了预测计算，计算结果被应用于该变电站保护小室的屏蔽设计。

| Abstract: | Based on the Method of Moment, a method to analyze the electromagnetic field generated by buses, connection lines of devices and power lines on electric power stations and substations while switches operating. The method uses currents on the metal conductors as unknown variables and can be used to analyze the electromagnetic fields in substation. In order to verify the presented method a simple model is analyzed. The results are compared with those of method of MTL (multi-conductor transmission lines), and the difference is small. A model of substation buses without load is set up, and the wave propagation of currents on the power lines and the electric field intensity are analyzed by this method and FFT. These results will be very useful in the next research. |
