电能质量监测系统研究现状及发展趋势

电能质量监测系统是及时发现和评估电能质量问题的重要手段。综述了电能质量监测系统整体架构方案、电能质量监测通信体系、监测中心软件系统的研究现状。在此基础上,分析了现有电能质量监测系统所存在着的缺乏完善统一的通信标准、各相关系统间缺乏交互和重用、缺乏对海量监测数据的有效管理和利用、无法支持与电力用户的友好互动等问题。阐述了智能电网中构建电能质量信息平台的重要性。指出监测数据的深化应用、提升兼容开放性以及基于云计算的架构是未来电能质量信息平台的发展趋势。

Current status and development trend of power quality monitoring system

The power quality monitoring system (PQMS) is the important means to timely detect and assess power quality problems. Firstly this paper reviews the current research status of PQMS overall architecture scheme, power quality monitoring communication system and monitoring center software. On this basis the problems in existing PQMS such as the lack of perfect and unified communication standard, the lack of interaction and reusability among the related systems, the lack of effectively management and exploitation of massive monitoring data, the lack of supporting for the parties involved to use the systems simultaneously are analyzed. Then the importance of power quality information platform (PQIP) in the smart grid is expounded. Finally the development trends of exploring monitoring data, improving compatibility and openness, and the cloud computing based architecture in the future PQIP platform are proposed.
