In the context of increasing the importance of power safety for national security, the security of power systems within the National Power Grid, must be an objective of major and constant interest for the national transmission and system operator. Evolutions in recent decades have shown the increase in vulnerabilities caused by: failure, destruction and/or disruption of technological infrastructures caused by acts of terrorism, natural disaster, negligence in service, work accidents of technical nature, technical incidents, criminal activities and lack of investment. For the critical analysis of the National Power Grid, 4 (four) possible risk scenarios with effects of instability of the power safety and with major effects on the national security were identified, described and evaluated: Risk Scenario 1 - Technical Incident, Risk Scenario 2 - Damage: Technical Incident Sequence, Risk Scenario 3 - Damage: Natural Disaster, Risk Scenario 4 - Damage: Terrorist Attack. The purpose of the paper is to describe and evaluate the Risc Scenario 1- Technical Incident (which is most prevalent) on the power substations and to prevent potential disturbances in the safety of the power supply to consumer.
