Circuit’s heterogeneity creates difficulties in analyzing stationary and dynamic processes. Following this, the numerical solutions contain components what physical doesn’t exist and lead to lower accuracy of obtained solutions. In this paper a modified procedure of finite difference method for calculating the dynamic processes in heterogeneous circuits was proposed. Numerical solutions regarding running processes in long lines with distributed and concentrated parameters were compared with those obtained by the FDTD method. The robustness and performance of the proposed procedure for numerical computation of the dynamic processes in heterogeneous electrical transmission lines was proved. |

Urmare a acestui fapt în solutiile numerice apar componente care fizic nu exista si conduc la diminuarea preciziei solutiilor obtinute. În lucrarea prezentata s-a popus un procedeu modificat a metodei diferentelor finite pentru calcularea proceselor dinamice în circuitele neomogene. Solutiile numerice privind derularea procesele în liniile lungi cu parametri distribuiti si concentrati s-au comparat cu cele obtinute cu metoda FDTD. S-a confirmat robustetea si performata procedeului propus de calcul numeric a proceselor dinamice în liniile neomogene de transport a energiei electrice.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-1304</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-10556</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-28010</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-15592</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> </cfPers_ResPubl> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-1304</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-1304-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> <cfFamilyNames>Берзан</cfFamilyNames> <cfFirstNames>Владимир</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-10556</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-10556-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> <cfFamilyNames>Patsyuk</cfFamilyNames> <cfFirstNames>Vladimir</cfFirstNames> <cfFamilyNames>Пацюк</cfFamilyNames> <cfFirstNames>В.И.</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-28010</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-28010-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> <cfFamilyNames>Rybacova</cfFamilyNames> <cfFirstNames>Galina</cfFirstNames> <cfFamilyNames>Рыбакова</cfFamilyNames> <cfFirstNames>Галина</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-15592</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-15592-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-08-20T24:00:00</cfStartDate> <cfFamilyNames>Постолакe</cfFamilyNames> <cfFirstNames>П.</cfFirstNames> </cfPersName_Pers> </cfPers> </CERIF>
