Risk Assessment of Power Substations Against Subversive Operations and the Provision of Solutions from the Passive Defence Perspective (The Case Study of a 400KV Power Substation)

One of the national and vital infrastructures of any country is the electricity network of that country. Vulnerability in power stations, which are the main artery in the cycle of electricity production, transmission and distribution, would result in irreparable damage. One of the ways to create a crisis is vandalism on electric substations, which causes public dissatisfaction, economic, social and even political crises on a large scale. One of the strategic goals of passive defense is to reduce this vulnerability and ensure the continuous functionality of vital and sensitive centers of the country against the actions of the enemy. Meanwhile, passive defense is known as one of the most effective and stable methods of defense against threats. The purpose of this research is to assess the risk of vandalism in substations from the passive defense point of view and provide solutions to deal with it. A 400 KV substation, being in the category of important and sensitive substations, is one of the most desirable goals to achieve this objective. For this purpose, in this article, a number of possible threats to the post were examined and the equipment was evaluated. In the evaluation of the final risk of sabotage threat, the auto-transformer, transformer and breaker were ranked at high, medium and low risk levels respectively, while the control room had the risk of medium upwards. In this research, the RAMCAP methodology was used as a research framework in risk assessment. Considering the network nature of the studied infrastructure, the network structures were used for information analysis and the multi-criteria decision-making method using the ANP method and Super Decisions software was used for the analysis.
