摘要
通过对供电网可靠性的研究,在网络等值法的基础上,先对复杂供电网进行等值化简,然后以故障模式后果分析法为基本原理,对供电网拓扑进行分析,建立故障关联矩阵,然后根据故障关联矩阵的计算得出各个负荷点的可靠性指标,继而综合各负荷点可靠性指标,得出整个供电系统的可靠性。通过对一个实际的算例进行计算分析,比较了不同接线方式下系统的可靠性。
Through the researches for the reliability of power supply system, the complex supply network is simplified based on network equivalent method, and the topology of supply network is analyzed and the fault incident matrix is established taking the failure mode and effect analysis (FMEA) as the basic principle. Then, the reliability index of each load point is obtained according to the calculation results of fault incident matrix. After summing up the reliability index of each load point, the relia- bility of overall power supply system is obtained. Through analyzing a practical example, the system reliability under different connection modes is compared.
