Greater complexity and interconnectivity across systems embracing electrical power technologies has meant that cyber-security issues have attracted significant attention. In this paper a simulation environment for intrusion detection system in IEC 61850 standard-based substation automation system is provided to test simulated attacks on IEDs （intelligent electronic devices）. Intrusion detection is the process of detecting malicious attacker, so it is an effective and mature security mechanism to protect electrical facility. However, it is not harnessed when securing IEC 61850 automated substation. To prove the detection capability of the system testing environment was developed to analyze and test attacks simulated with different test cases. It shows that the simulation environment works accordingly to various network traffic scenarios and eventually proves the functionality of intrusion detection system to be later deployed in the real IEC 61850 based substation automation system site.

The problem of logical node(LN)importance quantification in an IEC 61850 based substation automation system(SAS)is investigated in this ***,a weighted and directed static complex network model is established by analyzing the characteristics of SAS,according to IEC ***,we propose a method,which combines topology value and information adjunction value by introducing a first-order linear feedback controller to quantify the value of *** this basis,some definitions for equivalent network conversion are proposed to greatly reduce the complexity of the original network ***,the absolute value and relative value are introduced to quantify LN importance from the perspective of the node’s necessity and influence,***,simulation results of the case study demonstrate that the proposed method is effective and provides a broader and clearer perspective for viewing the logical node importance for IEC61850 based SAS.
