基于微服务的大电网在线安全稳定分析系统数据中台与架构设计

Microservice Based Data Integration Platform and Architecture Design of Online Security and Stability Analysis System for A Bulk Power System

在线安全稳定分析是揭露电网实时运行风险的重要手段,对于指导电网日内运行方式调整具有重要意义。现有在线安全稳定分析系统由于可扩展性不佳、人机交互困难、仿真模型存在偏差等原因,难以适应新型电力系统建设中出现的海量业务场景。为此,该文基于模块化、平台化的理念,提出一种面向电力调度运行业务的交互前台、微服务后台、数据中台及其融合的系统架构设计方法,并建立大电网在线安全稳定分析系统数据中台和整体架构。架构分析结果表明,按照所提方法搭建的大电网在线安全稳定分析系统架构能够支撑所需功能的运行,且具备灵活可扩展性。

Using online security and stability analysis to reveal the real-time operation risks of the power grid is of great significance to guide the adjustment of the intraday operation scheme of power grid. The existing online security and stability analysis systems are difficult to adapt to the massive business scenarios that appear in the construction of new-type power systems, due to lack of flexible extension ability, insufficient human-computer interaction, inaccurate simulation models, etc.Therefore, based on the concept of modularization and platformization, this paper proposed a system architecture design method for the human-computer interaction in front-end,microservice in back-end, data integration platform and their integration for power dispatching operation business, and established the data integration platform and software architecture of the online security and stability analysis system for a bulk power system. Analysis of the architecture shows that the architecture, built by the proposed method, of online security and stability analysis system for a bulk power system can support the operation of the required functions, with the ability of flexible extension.
