| 摘要: |
| 提出了一种基于录波数据对滤波器的断路器关合整定时间进行修正的方法。该方法从录波数据中提取断路器的关合时间、距离关合时间最近的电压过0时间等反映断路器工作状态的基本数据。通过对一段时间内录波数据的统计分析，找出断路器的关合时间偏差的系统误差和随机误差，并以此为基础对断路器的关合整定时间进行修正。应用效果表明:该方法简单、实用，不需要增加额外试验和费用，能够明显降低滤波器的合闸涌流，非常适合于换流站工作人员及时掌握断路器的运行状况，能够提高运维工作的效率。 |

| Abstract: |
| This paper puts forward a calculation method to set the closing time of circuit breaker based on recorded wave data. The basic data reflecting the working state of the circuit breaker is extracted from the recording data, such as the closing time, the closest voltage zero time, etc. According to the statistical analysis of the recording data in a period of time, the systematic error and random error of the circuit breaker closing time deviation are found, then the closing setting time of the circuit breaker is corrected based on this result. The application result shows that this method is simple and practical. It does not need additional tests and costs, and can obviously reduce the switching inrush current of the filter. The method is very suitable for the staff of the converter station to grasp the operation status of the circuit breaker in time and improve the efficiency of operation and maintenance.
