Dc Power Distribution System Research and Development of Public Information Model

提高电能质量,改善供电可靠性,降低输配电过程中的电能损耗,实现分布式电源安全有效地接入电网,直流配电不失为一种很好地尝试。对配电网更好地控制其基础在于对电网数据的采集,配网中包含多个不同系统的功能组件,而各组件间数据具有异构性,想要快速、便捷地获取配网信息,统一数据模型势在必行。本文中针对直流配网自动化的优势与不足进行了阐述,对配网模型拼接和实时数据交互进行研究。结果表明,利用CIM和CIS解决异构数据的交互,构建标准、开放的直流配电网相较现有的交流电网有明显优势,当为今后配网发展的有利方向。

In order to improve the quality of electric energy and the power supply reliability, reduce the power loss in the process of transmission and distribution and make the distributed power supply connected to the electricity grid safely and effectively, dc power distribution is a good attempt.For the better control of the distribution, network is the basis for grid data collection.The function of the distribution network contains a number of different system components, and the interrelationship between data has heterogeneity.If getting distribution network information quickly and conveniently, it is imperative to a unified data model.This article is in view of the advantages and disadvantages of dc distribution network automation, the distributionnetwork model and real-time data interaction.The result shows that making use of CIM and CIS to solve the interaction of heterogeneous data, build standards and open the dc power distribution network is not bad, and it is the favorable development direction of distribution network in the future.
