智能变电站同步相量测量装置研制

Development of Synchronized Phasor Measurement Units for Smart Substations

同步相量测量装置因测量精度高、数据具有精确时标等特点已成为电网的重要监测设备,但目前在智能变电站中应用不多,还处于探索阶段。提出应用于智能变电站的同步相量测量装置,该装置采用嵌入式软硬件平台,在实现传统同步相量测量装置相量计算、故障录波、实时纪录分析、实时通信等功能的基础上,实现了符合 IEC 61850 标准的设备建模、采样值报文接收和解析、与站内监控及其他智能电子设备数据共享等功能。

Synchronized phasor measurement units （PMUs） have become the important monitoring devices in power networks for high precision and accurate time tag of measurement data, but the applications of PMUs in smart substation are relatively seldom and tentative. The PMUs suitable for smart substation are presented, which adopt embedded software-hardware platform, not only demonstrate the functions of common PMUs, i.e. phasor calculating, fault recording, real-time record analyzing and real-time communication, but also have the capabilities up to IEC 61850 standard of modeling equipment, receiving and processing of sampling data message, sharing data with supervisory devices and other intelligent electronic devices in smart substation.
