This Procedure is developed according to the Technique of calculation of payment for overflowing of the reactive electric power between the electrotransferring organization and its consumers (further - the Technique) approved by the order of the Ministry of Fuel and Energy of Ukraine of January 17, 2002 N 19, registered in the Ministry of Justice of Ukraine on February 1, 2002 behind N93/6381, and Instructions for use electrical energy approved by the resolution NKRE of August 22, 2002 N 928, registered in the Ministry of Justice of Ukraine on November 14, 2002 for N903/7191.

This Procedure determines calculation of payment for overflowing of the reactive electric power between the electrotransferring organization and the railroad as the consumer of electricity.

Besides, the Procedure determines algorithm of distribution of payment for overflowing of the reactive electric power between electric utility systems (power supply systems) and the electrotransferring organizations.

This Procedure is obligatory for accomplishment by the corresponding personnel of NEK "Ukrenergo", the electrotransferring organizations and the railroads of Ukraine.

The procedure considers modern economic, technological and organizational features of the railroads, namely: receipt by the railroads of licenses for transfer and electrical supply ро to the regulated rate, implementation of electric utility service of traction loading from territorially remote traction substations connected among themselves by 27,5 network of kV of alternating current or 3,3 of kV of direct current, availability of transit overflowings of the electric power of other electrotransferring organizations that causes the necessity of distribution of share of losses in triobmotochny transformers and so forth.

2. General characteristics of objects of the railroads

General characteristics of the railroad as the object incorporating the site electrified by alternating current (daleedza / ~/) or electrified by direct current (further - DZE/=/), are illustrated by item-by-item structure of power networks of the railroad for determination of payment for overflowing of the reactive electric power in appendix 1 and appendix 2 respectively.

Settlement border of DZE (=) 10(6) kV of alternating current of traction aggregates (further - THAT contain on tires 35,).

2.2. Traction substations of DZE (~) provide transportation of the electric power by three levels of tension:

Uc - system tension on input of transformers of communication between power supply system and the electrotransferring organization 110(150) of kV. On this class of tension control of overflowing of active and reactive capacity generally in the high-level power networks is exercised. Control of the mode of power supply networks at this level is exercised by dispatching services of power supply systems as to one of the most important circuit and regime components of power supply systems;

Ut - the transit tension of communication with the electrotransferring organization 35, 10 kV. On this class of tension the electrotransferring organizations perform transportation of the electric power to other consumers. The circuit and regime condition of networks is controlled by personnel of the railroad;

On this class of tension control of overflowing of active and reactive capacity generally in the high-level power networks is exercised. Control of the mode of power supply networks at this level is exercised by dispatching services of power supply systems as to one of the most important circuit and regime components of power supply systems. In some cases system tension is voltage of 35 kV which performs power supply of the transformer of traction substation. Options of system voltage of 10(6) kV when food is performed by communication lines with the electrotransferring organization without transformers are possible;
