| 摘要: |
| 提出一种同杆架设多回线零序互感计算方法，指出线路的零序互感矩阵是一组独立的参数，线路不同运行方式下的零序参数可根据这些独立参数，由矩阵变换的方法计算得到。该方法不需要重复的试验实测，极大简化了零序互感参数的获取过程，提高了工作效率。同杆4回线路实际现场测试实例结果验证了该方法是正确的，且具有较高的精度。 |

| Abstract: |
| A method for calculating the zero-sequence mutual inductance of multi-circuit parallel transmission line on the same tower is proposed. It is pointed out that，the zero-sequence mutual inductance matrix is a set of independent parameters，based on which，the zero-sequence parameters of transmission line in different operation modes can be deduced by matrix transformation. Without the repeating experimental measurement，the proposed method simplifies significantly the acquisition of zero-sequence mutual inductance，which improves the work efficiency. Results of field test for a four-circuit parallel transmission line show its correctness and accuracy. |
