电气化铁道电能质量监测管理系统的研究

Study on Electrified Railway Power Quality Monitoring and Management System

针对电气化铁道的电能质量问题,本文提出了一种基于分布式体系软件平台构建的分层、分布式电气化铁道电能质量监测管理系统。该系统对谐波、电压波动和闪变、三相不平衡、功率因数等电能质量指标的监测,完全按照最新国家标准执行,检测标准可根据国标修订情况及时变更。该系统采用分层综合管理和嵌入式Internet技术,透明地支持多种通讯方式,能够实现监测设备管理、监视和测量、查询统计、数据分析和处理等功能。该系统在山东电网投入使用后,现场运行效果良好。

For power quality problems caused by the electric railway, this paper proposes a layered, distributional electric railway electrical energy quality monitoring and management system which is based on the distributional system software platform. The system monitors the electrical energy qualitative index of harmonic, voltage fluctuation, flicker, three phase unbalance, power factor and so on completely according to the newest national standard. The examination method can vary according to the GB code revision. Moreover the system uses layer built integrated management and embedded internet technology, transparently supports many kinds of communication way. This system can realize monitoring facilities management, monitoring and survey, inquiry and statistics, analysis processing data function and so on. It is proved well in Shandong electric power grid.
