摘要:

安全稳定系统在预防电力系统极端灾害下遭受大面积连锁停电事故中发挥了重要作用,针对现有单一数据来源无法适应当前对外部环境变化的不足,基于气象数据提出了使用时空地理网格的电网多源数据融合方法,研究了基于多源数据融合对电网计划安全稳定校验系统的影响,深入分析了安全稳定校核系统对电网预警计划的提升。该系统以某省级电网进行验证,将广域信息的采集范围从电力系统内部扩大到自然环境,将预警目标从单故障风险延拓到灾害下群发性故障风险。结果表明融合多源数据能有效改善电网安全稳定校核的数据单一化局面,完成系统所涉及的多源数据统一和整合,提升计算数据的可靠性,增强了电网安全稳定运行的能力。

Abstract:

A safety and stability system plays an important role in preventing the power system from large cascading failure blackouts under extreme disasters. Since the single-source data can hardly reflect the volatile weather conditions,multi-source data including the meteorological data for power grid planning are fused by spatio-temporal griding. The influence of multi-source data fusion on the security and stability verification system for power grid planning is studied, and the improvement of the proposed system on power grid's early warning is analyzed. Validated by a provincial power grid,the system extends its data collection range from the internal system to the natural environment,so as to extend early-warning objectives from single-fault risk to clustered fault risk caused by disasters. The results show that the fusion of multi-source data can effectively optimize the power network security and stability check based on single-source data,complete the unification and integration of multi-source data, improve the reliability of calculation data,and facilitate the application of power grid security and stability check.

Key words: multi-source data, security and stability, analysis and early warning, control decision, extreme disaster, power system, grid security
