| 摘要: |
| 电网故障阻抗轨迹动态分析(简称阻抗轨迹分析)是基于故障时刻智能电子设备(IED)及故障录波器记录下的COMTRADE文件,对录波文件智能解析,采用全周差分傅氏算法及阻抗向量计算法,逐点计算ZA、ZB、ZC、ZAB、ZBC、ZAC6种阻抗值,依据各阻抗值及设置的门槛值在PC机上动态绘制阻抗轨迹。阻抗轨迹分析软件采用VisualC 6.0编制,运用面向对象编程(OOP)思想进行软件设计,以Script文件格式动态编辑图形格式、属性,具体、形象地反映出继电器阻抗轨迹动作特性。 |

| Abstract: |
| The DAPFIT(Dynamic Analysis of Power net Fault Impedance Track) is based on the COMTRADE files recorded by IEDs and fault recorders. The intelligent analysis of recorded files is carried out,full-cycle Fourier algorithm and impedance vector algorithm are used to calculate ZA,ZB,ZC,ZAB,ZBC,ZAC in point-by-point way,and the impedance track is drawn dynamically on PC according to impedance values and settings. The impedance track analysis software is programmed by Visual C 6.0 with OOP design concept,and the graph format and property are edited in Script file format to reflect the action performance of relay impedance track visually and vividly. |
