Abstract: In the research work the accuracy of calculation of transient processes based on mathematical models generated using two multi-implicit methods, formulas of backdifferentiation and back-integration. Object of study - line 750 kV "Zachidnoukrainsk - Vinnytsia" for which were formed mathematical models based on analytical solution of equations of the transition process, the method of back-differentiation formulas and back-integration method formulas that have been implemented in the software complex MathCad. Research transients when switched on unloaded line system (source EDS) showed significantly higher accuracy of results obtained using the method of back-integration formulas ago, compared with the method of back-differentiation formulas.
