The transmission power contains double-circuit 35 kV overhead power line, which has been accomplished by ACSR conductors with cross-section 70 mm2, and 2 two-winding transformers connected in parallel. The length of the line is 30 km. The running parameters are following: resistance r0=0.422 Ω/km; impedance x0=0.432 Ω/km. The catalogued data of transformers are following: nominal power Snom=4 MVA; off-load losses △Poff-load=6.7 kW; △Qoff-load=40 kVAr; resistance Rt=2.6 Ω; reactance Xt=23 Ω.

The plant is fed by this transmission power. It consumes power S=4.2 MVA under cosφ=0.9.

The level of voltage at the power source buses VPS=37 kV.
