电力故障波形再现及分析系统的开发

Development of Power Fault Waveform Recurrence and Analysis System

针对调度端的具体要求及目前电力系统主站故障录波分析软件的不足,采用Visual C++6．0开发了一套电力故障波形再现及分析系统,主要包括数据远传、格式转换、信息管理、故障分析等模块,可将不同类型的故障录波数据转换为标准的COMTRADE格式,使调度端能对全网的故障数据进行统一管理,实现波形再现和分析、谐波和矢量分析、功率分析及故障分析等常用功能。此外,文中还阐述了应用 Visual C++6．0开发时的几个具体问题及其解决方法,如远传通信、COMTRADE格式数据的装载结构设计、图形用户界面显示及图形界面滚动特殊设计等问题。

To meet the requirement of dispatching center and improve the defects in the master station＇s fault record analysis software nowadays, a power fault waveform recurrence and analysis system, in which following modules such as remote data transmission, format conversion of data, information management and fault analysis are involved, is developed by use of Visual C＋＋6.0. With this system different types of recorded fault data can be transformed into standard COMTRADE format, so at the dispatching center the fault data of the whole power network can be unitedly managed and the commonly used functions such as waveform recurrence, harmonic and vector analysis, power analysis and fault analysis are realized. In addition, solutions of some concrete problems in the application of Visual C＋＋6.0, which appear during the development of remote transmission and communication, design of loading structure of COMTRADE formatted data, display of GUI and the special design of scrolled graphical interface, are expounded.
