The paper considers the development of inter national electric connections and power system interconnections in Eurasia, including Europe, the post-Soviet space and South-East and North-East Asia. International integration energy projects with the participation of Russia are presented. Among these projects are Baltic, the Black Sea, and Caspian energy rings, the South-Central Asian international power system interconnection, the energy bridge from Russia to Japan and others. The role of the Russian UES in the development of Eurasian power system interconnection is analyzed. Presented performance study results of power system interconnection in Northeast Asia demonstrates high efficiency of this power system interconnection.

Keywords: international electric connections and power system interconnections, trend, integration, systemic impacts, energy ring, energy bridge

The article considers the application of power systems steady-state
stability assessment for reliability support when emergency shutting
down of main transmission lines. Jacobian zero crossing for post-fault
condition equation system is considered. Instead of determination of
critical sections the suggestion is given to calculate and control power
flow through transmission line when maximum power angle.

Keywords: steady-state stability, critical section, Jacobian, power angle

One of the project documentation sections is the thermal resistance calculation for 110–750 kV overhead ground-wire cable in the event of short-circuit current. Usually for such calculation simple and proven methodology guidelines developed in the USSR in 1976 have been used.

After a release of a new edition of methodology guidelines by PJSC “FGC UES” designed as a company standard in 2014 the situation has been changed. As it turned out the new document is more difficult and requires taking into account a significant number of initial data. Therefore, designers have to seek author’s help on the commercial basis. We will try to un der stand the difference between documents dated 1976 and 2014.

The article analyzes the coefficients in the current load formulas for cables with XLPE insulation, the derivations of formulas is given in. It is shown that it is not suitable for practical calculations for the existing formulas active resistances of current-carrying cores of AC cables. A simplified formula is proposed for determining the active resistances of the cores for an alternating current with respect to the resistance of cores to a direct current. The formulas are proposed for calculating the external thermal resistances of the cables laid in the trough, with the top flush with the soil surface, and in the ground with three layers of backfill soil.

Keywords: electric cables, skin effect, dielectric losses, thermal resistance
