Examples
- Applying relative arithmetic to all kinds of faults and calculating off - line , we can master time - distance relation chart for all kinds of faults . computation indicates : when transmission lines occur faults , the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance . the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle , calculating work voltage by using fault component , calculating the torque created by a phase comparator or a magnitude comparator
实际的计算表明：输电线路发生故障后，用故障前后的数据同时充满保护算法的数据窗，对于快速切除近区故障具有很重要的意义；同时利用故障前后的数据，下述方法可以比较好地实现距离保护的反时限特性：直接用全周傅里叶算法进行阻抗计算；采用工频变化量阻抗继电器进行工作电压的计算；采用转矩的思想进行转矩的计算。 - The paper expounds the design and implement based on the mixed pattern of c / s and b / s . it consists of demanding analysis s system structure , network structures data flowing diagrams function module . . entity relation chart of database and the application of key techniques . it gives a detailed expounding about database ' s dynamic links
