地区电网在线安全稳定预警与辅助决策系统

On-line security and stability analysis with pre-alarm and decision-making supporting system for regional power grids

通过对目前电网在线动态安全分析领域的研制背景分析,提出了地区电网安全稳定实时预警系统的可行性,详细介绍了系统的主要功能、关键技术和性能指标。地区电网安全稳定实时预警系统从SCADA/EMS实时获取在线数据,利用分布式并行计算平台快速找出各类安全隐患,给出综合智能告警信息,展示给调度员,可方便地实现地区电网与省级电网不同调度控制中心的信息集成。通过在洛阳电网的研发和实施验证了该系统不仅可以大幅度提高本地区电网的实时安全预警能力,还能够及时发现本地电网模型和数据中的错误与异常信息,自动报警并给出详细信息,大大提高了系统模型的准确性,是未来地区电网调度运行必不可少的工具。

The main functions, key technologies and performance indicators of the on-line security and stability analysis with pre-alarm and decision-making supporting system for regional power grids are recommended in real-time grid monitoring and real-time pre-alarm. The development background of the field of dynamic security analysis of power network is analyzed, and the feasibility of regional power network security and stability is proposed. The system reads on-line data from SCADA/EMS and rapidly identifies all kinds of potential safety problems and the abnormal information from the model of power grids with the use of distributed parallel computing platform, it can quickly find out all kinds of potential safety problems, give a comprehensive intelligent alarm information, and provide accurate alarm correct treatment strategies for dispatch staff to adjust the different degrees of control center of information integration. The system is verified by power development and implementation in Luoyang, which not only greatly improves local grid real-time safety early warning ability, but also enhances the accuracy of the system model by finding data errors and abnormal information from the local power grid model. It has been proved that, this system is an essential tool for the future development of the regional power grid.
