例句与用法
The recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real - time demands . the reserch shows deficiency existed in the prevenient principle of transient current protection , so a new improved scheme of transient current protection is proposed . the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis . the study shows that operate of transient protection is correct when the bus distribution capacitance change . other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated , because the trip is incorrect at this time ; the features of transient current and it ' s energy is different between the fault and thunder over - voltage in transimission line , and them can be identified ; the ratio of high frequency component of current in serise capaciters compensation line , svc and hvdc system is far little than fault transient current , so all of them do not affect the working of trasient current protection 应用功率谱估计方法讨论了故障高频暂态噪声信号在频率轴上的分布情况,利用功率谱分析结果实现的非参数化系统辨识方法研究了母线分布电容对电流高频暂态信号的衰减特性。论文的后半部分(第五,六,七章)着重分析了现有基于故障电流的暂态保护原理和判据存在的问题,提出了新的实现方案,并讨论了暂态电流保护的运行性能。利用多分辨分析和小波分解快速算法构成的递推暂态保护判据,可以准确区分故障线路和非故障线路,实现超高速暂态电流保护,计算更为简单方便,计算速度更快。
