Containment of Blast Phenomena in Underground Electrical Power Plants.

Gas explosion accidents in electrical power plants, can be originated by electrical faults in components containing oil for insulation, such as transformers, junction boxes, etc.; a ground discharge can cause the pyrolisis of part of the oil and the production of a gaseous mixture which generates fires or deflagrations in contact with air. A deflagration gives rise to a pressure shock wave which can propagate throughout the underground plant, if not suitably confined. Flui-dynamic, structural and in some cases fluid-structure interaction analysis are needed to evaluate the overpressures occuring during the blast phenomena and the consequent damages on structural elements. In the present paper a numerical approach to this kind of problems is proposed and applied to a case study dealing with a typical transformer cell in an underground power plant. The fluid-structure interaction code PLEXIS-3C is used to perform both fluid and structural fast dynamic computation.JRC.(ISIS)-Institute For Systems, Informatics And Safet

Simulations and calculations as verification tools for design and performance assessment of high-voltage equipment

In the past few decades, the revolutionary breakthrough in the semiconductor industry has greatly increased the computational power of computers.Taking advantage of these hanges, engineering oriented software companies have developed a wide spectrum of software. Industries have responded to this new generation of software and have adopted some of it to improve design efficiency or as a development tool. Power industry, manufacturers, test laboratories and institutes have also created their own add-on components to commercial software In response to the increasing role of software in the power industry, Study Committee A3 decided to evaluate existing simulation technology to determine the extent to which it can be used as a verification tool to enhance the understanding of high voltage equipment, to extrapolate test results or to replace some of the tests
