摘要
国网电力调度数据网是用于电厂电力生产调度的专用数据网络,其安全稳定运行直接关系到电网与电厂间的功率负荷等数据的实时传输可靠性。电厂电力调度数据系统在关键重要设备中采取了冗余配置的结构,提升系统的可靠度。通过分析电力调度数据系统的结构与逻辑关系,构建其故障树模型。通过对其层级划分,结合底层设备的可靠性参数,逐层计算系统可靠度,通过仿真实验,定量计算了具体的可靠性指标。根据仿真实验计算结果,构建更加合适的维护策略。
The power dispatching data network of State Grid is a special data network for power production and dispatching in power plants,which safe stable operation is directly related to the real-time transmission reliability of power load data between State Grid and power plant.The power dispatching data system adopts redundancy configuration structure in key equipment to improve the reliability of the system.This paper analyzes the structure and logical relationship of power dispatching data system and constructs its fault tree model.The system reliability is calculated layer by layer based on the hierarchical division and the reliability parameters of the underlying equipment.The specific reliability index is calculated quantitatively through simulation experiment.Considering the simulation results,a more appropriate maintenance strategy is constructed.
