故障关联矩阵下弹性配电网可靠性评估
Reliability assessment of elastic distribution network based on fault correlation matrix
摘要
Abstract
The elasticity of the distribution network indicates the ability of the system to restore its original state after interference,and the frequent occurrence of natural disasters requires that the distribution network can not only operate reliably under normal conditions,and but also maintain the necessary capabilities for extreme disasters.Accordingly,a reliability evaluation method of elastic distribution network based on fault incidence matrix(FIM)was proposed in this paper.With FIM,the explicit analytical calculation of the reliability,elasticity and power supply capacity of the distribution system can be achieved by using simplified matrix algebra and Boolean operation,which saves the repetitive search work of fault enumeration in the evaluation process,and the calculation time,and can be applied to the complex structure of the distribution network and easy to expand.The final results show that the calculation time of the proposed method is only about 0.055s,which is reduced by 87％and 75％respectively compared with that of the fault diffusion algorithm and the block algorithm.关键词
