GRASB

Scenario-based basic principles and innovative methods to reduce the risk of the outage of the electric power supply taking into account the impact on the population

Abstract

In the framework of the funding program „Forschung für die zivile Sicherheit” the project GRASB was supported by the Federal Ministry of Education and Research (BMBF) in collaboration with the project management agency VDI Technologiezentrum.
The sub-project „structure and load specific representation of the hazard potential for risk identification” was focused on the aspect of mechanical vulnerability and permanent destruction of neuralgic structures of the electric power supply infrastructure.
Special attention was drawn to the load cases of impact from external sources. These events usually originate from natural disasters, accidents and deliberate acts. For infrastructures in the field of energy power supply these lead for example to load cases like earth quakes, explosions after accidents or acts of sabotage or plane crashes induced by hijacking or technical problems.  The vulnerability of the selected large-scale structures electric power transformation substation and boiler house of a power plant was investigated by numerical simulation.
The question was: which is the critical event height and intensity leading to a permanent damage of the critical infrastructure? Are there possible barriers which reduce the vulnerability of the endangered structures?

Project results and deduced services

Wölfel used the know-how generated in the project to extend its range of services for the energy business and to advance the used simulation techniques especially with regard to the impact from external sources. This particularly includes the assessment of resilience with respect to load cases like earth quake, blast or plane crash. The methods developed in the project resulted in services “risk assessment in the field of conventional electric power supply” and particular engineering services for the reduction of failure risk for conventional power plants and connected grids. Customers are operators of respective plants of which their service security are enhanced.

By simulation of the vulnerability indicators for resilience enhancement of structures can be given. In the sub-project two scenarios were worked on:

  • The vulnerability of electric switching stations was investigated by simulations of the load case earth quake
  • By simulation of a blast as result of an explosion of a high energy recipient the vulnerability of an endangered plant structure and the possibilities of resilience enhancement by barrier installation was investigated
