| 摘要: |
| 时序数据库使记录带时标量测数据成为可能，因此提出了基于时标量测的电网实时预警方案。该方案包含４个核心技术点，即系统数据的分流处理、脚本驱动的告警规则定义与执行、基于运行历史数据挖掘的运行状态预测告警、告警结果精细化的展示以及多样化的辅助决策分析，实现了电网模型数据与时标量测的实时数据、历史数据融合应用，解决了电网量测跳变难以捕捉、告警准则单一、电网运行异常时缺乏预警手段等问题。所提方案在实际工程中的应用结果表明，其提高了预警系统的准确性和有效性。 |

| Abstract: |
| Since the time-sequence database stores the measurements with timestamp，a real-time grid alarm scheme based on the measurements with timestamp is proposed，which contains four key technologies：the shunt processing of system data，the script-driven definition and execution of alarm rules，the operating state alarm based on historical data mining，the detailed alarm display and diversified supplementary decision-making analysis. It realizes the fusion and application of grid model data，real-time measurements with timestamp and historical data，and the technical improvements，such as the capture of measurement jump，the enrichment of alarming rules，the supplementary alarm means for abnormal grid states，etc. The application of the proposed scheme in actual projects verifies its correctness and effectiveness. |
