【摘要】：随着配电网信息化建设的不断发展,配电网领域所涉及的数据信息也越来越多,这些数据不仅包含了电网电压、电流等运行信息,还包括地理、天气等各类相关信息,通过对这些数据的采集存储和有效管理可以提高对配电网全面监测的能力,并为配电网的各种应用系统提供可靠稳定的数据支持。由于配电网的数据来源种类繁多,包括如SCADA系统数据、PMU系统数据、电能质量监测系统数据等,不同数据源系统的需求及应用场景各不相同,在数据格式、精度等各方面均存在着较大的差异。同时,这些异构的多源数据还存在数据冗余、缺失等异常情况。另外,配电网的数据采集系统还面临着厂站分布广泛、通信规约种类繁多、终端采集设备繁杂等特点。以上这些配电数据特点制约了配电网运行决策的应用,使得各个配电应用场景难以相互支撑。本文对配电网大数据的来源做了分析,并在其分析结果之上总结了各数据源的基本特征,然后基于IEC 61970及IEC 61968标准建立配电网多源数据统一标准接口,并进一步设计了配电网多源数据采集系统。对开发过程中使用的相关技术规范以及遇到的问题都进行了深入的研究,基于ROA架构开发了配电网多源数据服务系统,解决了多源数据统一接入的问题,并在此基础上实现了多源数据采集系统的主要功能,主要应用数据采集系统的实时召测与定时召测功能进行多源数据的收集,最终将数据信息结果以可视化界面、检测结果以PDF报告的形式进行展示,为配电网进一步的高级应用分析提供可靠的信息支撑。
[Abstract]:With the continuous development of distribution network information construction, more and more data information is involved in the field of distribution network. These data not only include the grid voltage, current and other operation information, but also include all kinds of related information, such as geography, weather and so on. Through the collection, storage and effective management of these data, the ability of comprehensive monitoring of distribution network can be improved, and the reliable and stable data support can be provided for various application systems of distribution network. Because there are many kinds of data sources in distribution network, such as SCADA system data, power quality monitoring system data, different data source system requirements and application scenarios are different, in the data format, There are great differences in precision and other aspects. At the same time, these heterogeneous multi-source data also exist data redundancy, missing and other anomalies. In addition, the data acquisition system of distribution network also faces the characteristics of wide distribution of plant and station, variety of communication protocols and complex terminal acquisition equipment. The above characteristics of distribution data restrict the application of distribution network operation decision making it difficult to support each other. In this paper, the source of distribution network big data is analyzed, and the basic characteristics of each data source are summarized on the basis of the analysis results. Then, based on IEC 61970 and IEC 61968 standards, the unified standard interface of distribution network multi-source data is established. Furthermore, the multi-source data acquisition system of distribution network is designed. The related technical specifications and problems encountered in the development process are deeply studied. Based on the ROA framework, a multi-source data service system of distribution network is developed, which solves the problem of unified access of multi-source data. On this basis, the main functions of the multi-source data acquisition system are realized. The functions of real-time call and timing call of the data acquisition system are mainly used to collect the multi-source data. Finally, the result of the data information is visualized. The test results are presented in the form of PDF report, which provides reliable information support for further advanced application analysis of distribution network.
