U cilju identifikacije slabih tačaka elektroenergetskog sistema (EES) razvijeni su višestruki regresijski modeli.Na temelju određenih pokazatelja pouzdanosti (DLOL,DNS),te indeksa naponskog kolapsa(SDC) definirana je veza između ovih pokazatelja i stanja pojedinih komponenti EES.Regresijski koeficijenti indiciraju učešće svake komponenete EES(generator,vodovi,podstanice) u vrijednosti DLOLO,DNS i SDC.Ovakve informacije pomažu kod preduzimanja mjera povećanja pouzdanosti i sigurnosti EES. |
Multiple regression models designed to identify the weak points of power system arev presented.ON the basis of the determined reliability indices(DLOL,DNS),and by taking into account the apparent power differencecriterion SDC as a voltage collapse proximaty index,one can define the mutual relatioship between these indices and the states of the particular power system components.The reggresion coefficients of MRMs indicate participation of each power systems component whit regard to DLOL and SDC.Such information helps take measures of increating the power system reliobility and security.Subject-related results obtained in the Bosnian utility are given. |
