At present, all of algorithms used widely in our country to fault location of the single-circle high voltage over-head transmission line, based on fundamental components of one-terminal information, have some disadvantages. 根据目前广泛应用的单端电气量的基频分量实现单回高压架空输电线路故障测距的其各种算法尚存在的不足之处,如求解出现伪根或可能存在迭代不收敛的问题;
In this paper according to the transmission line, shielded theory. two-port network. signal processing theories and filtering theories, the anti-inference technology of information device connecting system has been studied. 本文依据传输线理论、屏蔽理论、二端口网络理论、信号处理理论和滤波理论,对信息设备互连系统的抗干扰技术进行了研究。
The containment relationship among performance indicators is also analyzed to provide theoretical support for the transmission line performance evaluation. Finally, in real-time environment, the data features of performance indicators are analyzed based on stochastic process theory according to the changing and procedurally-replicating SCADA information. 最后,在实时环境下,根据变动的、过程化复现的SCADA信息,基于随机过程理论,实时分析性能指标的数字特征规律。
Although the transient duration of fault on transmission line is short, it contains a wealth of fault information, which makes it possible to achieve a fast and accurate classification and location. 高压输电线路故障产生的暂态量虽然持续时间短,却蕴含了丰富的故障信息,这为实现快速、准确的故障分类与定位提供了可能性。
