Abstract
The resilience of a system can be achieved by reducing its probability of failure as well as reducing the consequences from such failures and the time to recovery. Quantification of resilience is first approached from the broader societal context, from which the engineering sub-problem is formulated as an important building block of the integrated tool ultimately needed. Nonlinear structural responses are considered, as well as the impact of retrofit or repair. Impact on time to recovery is considered in all cases. The proposed framework makes it possible to relate probability functions, fragilities, and resilience in a single integrated approach, and to further develop general tools to quantify resilience. The high voltage transmission system is typical engineering system which requires the assessment of the resilience as the measure for evaluation of the po- tential hazard event development. In this respect the resilience of the high voltage transport system is highly vulnerable: central generation creates high value targets, long vulnerable transmission lines, unique high voltage transformers, vulnerable substations. The assessment of the resilience of the high voltage transmis- sion system is based on the evaluation of the resilience index as the result of the sudden changes of the char- acteristic indicators.

Energy losses represents nowadays between 2% and 4% of total energy electric power transmission
In this analysis of the Resilience Index of High Voltage Transmission System a following indicators are take into a consideration, as shown on Figure 5
The potential possibility of the high voltage transmission system is to reach limits leading to the catastrophic events require the investigation of the cases which might be the qualitative measure of the stability of the system
Summary
Energy losses represents nowadays between 2% and 4% (depending of local climatic conditions) of total energy electric power transmission. The high voltage system is highly vulnerable: central generation creates high value targets, long vulnerable transmission lines, unique high voltage transformers, vulnerable substations [1] This factor should reveal the current state of play, the changes compared to previous years and should allow a future outlook of the trends in network development. As an incentive it should have positive effects directly on the network operators’ revenues in case of an improvement of the situation (less grid losses, more distributed generation compared to previous year). The high voltage system is highly vulnerable: central generation creates high value targets, long vulnerable transmission lines, unique high voltage transformers, vulnerable substations. The complex system of high voltage transmission system is characterized with the specific number of the indicators reflecting individual properties of the system, as shown on Figure 2
