WGL-3大型发变组微机故障录波及监视分析系统

WGL-3 generator-transformer unit fault recording and supervisory analysis system

介绍了新型WGL-3大型发电机-变压器组(简称发变组)微机故障录波及监视分析系统的硬件、软件结构及功能。该系统用于在线监视大型发变组的运行状态,前置机能够有效检测发变组运行中的各种故障及异常运行工况,并能灵敏地启动录波;后台监控主站软件对故障前、后的数据进行分析。硬件采用数字信号处理器(DSP)高速数据采样,多台发变组微机故障录波装置通过TCP/IP协议组成故障录波局域网络,采用IEEE标准电力系统暂态数据交换通用格式(COMTRADE)和Huffman压缩,可以实现数据无失真远传。该系统已在三峡电厂等现场投运40多套,实践证明该装置具有良好的抗干扰能力和实用功能。

WGL- 3 high power GTU（Generator- Transformer Unit） fault recording and supervisory analysis system is introduced,including the structure,function and performance of its hardware and software. The system is used to online monitor operation states of high power GTU,the front-end computer detects different abnormal or fault conditions effectively and starts recording sensitively,and the supervisory station has fault analysis software. With high speed data sampling based on DSP （Digital Signal Processor）,multiple WGL- 3 GTU fault recorders are interconnected as a fault -recording LAN（Local Area Network） through TCP/IP protocols,and the fault data compressed by Huffman arithmetic are losslessly and remotely transmitted with IEEE COMTRADE （COMmon format for TRAnsient Data Exchange） standard data-format. More than 40 systems have run on site, such as the Three Gorges hydro plant and site operation proves its better anti-noise ability and practical functions.
