输电线路雷击组合测距新算法OA北大核心CSCDCSTPCD
A new combined lightning locating algorithm for transmission lines
针对现有输电线路雷击定位方法存在的诸多缺点,提出一种新的测距算法。该算法综合考虑雷电定位系统(LLS)和单端行波测距法的特点及适用性。首先利用现有 LLS 判断出雷击的大致距离,然后利用该距离及线路参数来准确识别故障点反射波和对端母线反射波到达测量端的时刻,进而利用单端行波测距法精确测得雷击距离。该算法克服了地理环境、探测站距离等因素对LLS定位精度的影响,以及单端行波测距因无法准确辨识故障特征波前而导致测距精度无法保证的不足。在雷击故障时,测距…查看全部>>
For the defects of existing lightning location methods for transmission lines, a new combined lightning locating algorithm is proposed. It takes into account the characteristics and application of Lighting Location System (LLS) and one terminal location methods. Firstly, existing LLS is adopted to recognize the lightning distance approximately. Then, the accurate arriving times of wave fronts are obtained with this approximate distance and the line parameter…查看全部>>
