Simulation and analysis of ferroresonance in power circuits with a nanocrystalline magnetic materials

Popis výsledku v původním jazyce

An increasing requirement on electrical power systems to be more economically effective and reliable as well, led to the application of new materials in the production of power and instrument transformers. Mainly the use of amorphous and nanocrystallinematerials for magnetic cores offers a considerable reduction of electrical losses and also expand the frequency range of the instrument transformers. On the other hand, these positive effects can produce some difficulties when the transients occur (transformer energization/deenergization, ferroresonance effect etc.). The ferroresonance effect can produce overvoltage, which is not allowable for the electrical power grids operation and is dangerous for insulation systems. The paper deals with different mathematical models of ferromagnetic materials in order to simulate various transients, especially ferroresonance. The aim is to describe and compare the power system behavior for the cases, when the magnetic cores are made of nanocrystalli
