The paper presents design ratios for calculating power losses, efficiency factor and its maximal value for a long-distance electricity transmission. Universality of these ratios with due account of electromagnetic wave propagation nature and intermediate connections and multifunctional application are considered in the paper. The ratios permit to construct algorithms while designing, pricing at wholesale electricity market and can be used in the training process.

The paper contains a mathematical simulation of transient parameters of vertical grounding electrodes for the first and subsequent short strokes of a lightning current. Results of the research show that transient resistances of grounding electrodes change appreciably in time. The transient resistances are always higher in the moment of voltage maximum then in the moment of current maximum. The dependences of transient resistances on grounding electrode length at different ground conductivity and lightning current parameters (first and subsequent short strokes) are obtained in the paper. The paper proposes an approximate criterion for estimation of grounding electrode equivalent length at transient condition that considers short stroke parameters of the lightning current and ground conductivity.

The paper investigates starting-up modes of powerful asynchronous motors used at gas-compressor units which are applied for oil and gas production and transportation. Impact of motor starting-up on GRID mode for various variants of a scheme structure is considered in the paper. The paper presents investigation results taking 7 MW capacity motors as an example. The motors concerned are applied at compressor units used for oil production inAzerbaijan.

The paper considers a load diagram leveling as of one of the means for higher operational efficiency of a power system and power saving. In order to reach the target it is supposed to use peak devices of the distributed generation (peak mini-power complexes) on the basis of cutting edge power equipment – micro-turbines of 30 kW–1MW capacity.
