摘要
故障录波数据是电力系统故障分析和保护动作判断的重要依据。针对目前故障录波装置数据分析非具体化、微机保护装置动作过程非可视化的现状,提出一种故障数据分析处理系统。通过将仿真数据或故障录波数据转换为COMTRADE格式的标准文件后输入系统,然后对故障数据进行滤波和预处理,模拟具体保护装置中各类保护模块的动作逻辑并进行分析。该系统能对不同故障条件下保护装置的动作特性,以及同一故障下不同保护元件的动作特性进行分析比较,可以深入了解微机保护装置的运行特点,分析评价实际保护装置的性能。
The power fault recording data are the significant basis of fault analysis and protection action judgment in a power system.In view of the problems of current fault recorder data were not analyzed in detail,microcomputer protective device working process non-visual,a scheme of fault data analyzing and processing system is proposed.After different types of recorded fault data and simulation data transformed into standard COMTRADE format file,we input them to system,filter and pretreatment,imitate and analyze the actual protection equipment kinds of modules operation characteristic.This system can make analysis and comparisons of operation characteristics of protection devices under different fault conditions and operation characteristics of different protection components or devices under the same fault conditions,which provide a powerful tool for the deep understanding in the operation characteristics of microcomputer protection device and the protection device performance evaluation.
