考虑IED信息物理影响的配电网可靠性评估OA

Intelligent electronic devices(IED)play an important role in connecting the information layer and the physical layer in the cyber physical system(CPS)of the distribution network.In order to effectively evaluate the reliability of the CPS of the distribution network,based on the Markov two-state modeling of general components,a series-parallel hybrid modeling method considering the detection and control functions in IED components is proposed.And the connectivity,timeliness and accuracy of the information transmission link were comprehensively considered,as well as the possibility of the system being attacked by the cyber.The process and power outage time after the system failure were analyzed,and the CPS reliability index of the distribution network was calculated by using the sequential Monte Carlo simulation method to quantitatively evaluate the reliability of the system.Finally,the IEEE RBTS Bus 6 distribution system is tested to verify the effectiveness of CPS reliability evaluation and the influence of different information factors on system reliability.
