基于分布式技术的用电信息采集主站系统设计与应用

随着用户侧数据采集设备的发展及电网业务对用户侧采集数据的深化应用,当前电力用户用电信息采集主站系统在数据采集、计算、入库等方面出现瓶颈,无法满足业务快速发展的需求.针对营销数字化转型发展的需要,基于分布式架构、异步网络、并行计算与分布式存储等技术,文中提出一种具有高频实时采集特征的主站系统技术方案,在采集通信层、任务调度层、分布式存储层及并行计算层4个层面全面解决高频并发交互、复杂任务调度、海量数据存储及实时计算的效率问题.通过中国某省级工程应用表明,所提出的方案可显著提升用电信息采集主站的采集能力,改善集中式采集主站性能.

Distributed Technology Based Design and Application of Master Station System for Power Consumption Information Acquisition

With the development of user-side data acquisition equipment and the intensified application of power grid business to user-side acquisition data, the current main station system for user power consumption information acquisition has bottlenecks in the aspects of data acquisition, calculation and storage, which cannot meet the demands of rapid business development. In order to meet the demands of marketing digital transformation and development, based on the distributed architecture, asynchronous network, parallel computing and distributed storage technology, this paper proposes a technical scheme of master station system with high-frequency real-time acquisition characteristics. This scheme comprehensively solves the efficiency problems of high-frequency concurrent interaction, complex task scheduling, massive data storage and real-time computing in the four levels of collection and communication layer, task scheduling layer, distributed storage layer and parallel computing layer. The application of a provincial project in China shows that the proposed scheme can significantly improve the acquisition capacity of the master station for power consumption information acquisition, and improve the performance of centralized acquisition master station.
