广域分布式电能质量监测系统数据整合技术研究

摘要

随着电能质量监测终端及电能质量数据的逐步增多，传统的电能质量监测系统在数据存储及计算方面已经开始面临较大的压力。此外，由于电能质量数据源的多样性和异构性，使得各类数据信息耦合程度非常低。针对上述问题，提出了一种广域分布式电能质量监测系统的数据整合技术方案，并通过对数据集成、数据清洗、分布式数据存储与读取及数据共享等关键技术的研究，可以实现电能质量多源异构数据的整合，为电能质量现象的分析提供了更为详细、优质的数据基础。此外，通过数据的共享，也可使电能质量数据在其他数据系统中得到更好的利用。%As the quantity of power quality monitoring equipment as well as power quality data is increasing, the power quality monitoring system has more pressure to deal with the data storage and data calculation.Besides, the diversity and heterogeneity of power quality data makes the coupling degree of data information rather low.For the issues above,a data integration technique was proposed for wide-area distributed power quality monitoring system.The system can integrate various heterogeneous power quality data through the techniques of data collecting, data cleaning,distributed data storage and data sharing,and thus provide a more detailed and qualified data for power quality analysis.Besides,power quality data can be properly used in other power data system with data sharing.
