Approved by the Decision of Electrical power Council of the CIS of October 13, 2006 No. 30

The instruction for investigation and accounting of technological violations in work of Interstate electrical power objects *

Terms and determinations

Technological violation - the inadmissible variations of technical condition, technological parameters of work of electroinstallation, its elements which caused their conclusion from work or damage during operation, violation of indicators of electric power quality.

Abnormally admissible overflow of capacity in the section of network - the greatest admissible overflow in the postemergency or forced modes.

Emergency operation of power supply system - the power supply system mode with the parameters which are going beyond requirements of technical regulations which emergence and long existence pose inadmissible threat to life of people damages to machinery also lead to restriction of giving of electrical and heat energy in the amounts established in regulating documents on power of the State Parties of the CIS.

Forced sharp power supply systems - the power supply system mode in case of which loading of some sections is higher than the most admissible, but does not exceed abnormally admissible.

Deficit of capacity of power supply system - the lack of capacity of power supply system determined by difference between required capacity of power supply system in case of normative indicators of its reliability and quality of electrical energy and working capacity at present time.

Dynamic stability of power supply system - capability of power supply system to return to the set mode after considerable indignations without transition to the asynchronous mode. The most admissible overflow of capacity in section the setinaibolshy overflow in section meeting all requirements to the normal modes.

Interstate electrical power objects - set of the electroinstallations serving for communication of electric utility systems of neighboring states - members of the CIS and ensuring their parallel work.

Intersystem overflow - the capacity/electric power transferred but межсистемньм to bonds.

Intersystem communication - the line or the site of power line which are directly connecting power plants or substations of different power supply systems.

Reliability of electric utility service - capability of power supply system to provide to consumers delivery of electrical energy (capacity) according to the declared sizes and contractual commitments in case of observance of the established electric power quality regulations.

Not balance of capacity - temporarily arisen violation of balance of capacity of power pool caused frequency variation from nominal rate.

Misoperation of RZA and PAS - the failure, the wrong operation of the device determined by comparison of the requirement proceeding from purpose of the device with the event which took place actually; the wrong operations of RZA and PAS devices are excessive and false operations.

The normal mode of power supply system - the power supply system mode in case of which all consumers are supplied with electrical energy according to agreements and dispatching schedules and values of technical parameters of the mode of power supply system and the equipment are in limits is long admissible values, there are normative operational reserves of capacity and fuel at power plants.

Supervisory control the energosistemoytsentralizirovanny management of the power supply system mode exercised of the System Operator or other subjects of supervisory control.

Parallel work of electric utility systems of the State Parties of the CIS - joint operation of electric utility systems with single frequency in merging of electric utility systems of the State Parties of parallel work.

Parameter of electrical energy - the size which is quantitatively characterizing any property of electrical energy; understand tension, frequency, form of curve of electric current as parameters of electrical energy.

Postemergency operation of power supply system - the mode in which the power supply system is after localization of technological violation before establishment of the normal or forced mode.

System Operator - the organization performing centralized quickly - technological (dispatching) management of operating modes of the Single, Integrated power system of the state (states), ensuring reliability of power supply system and indicators of electric power quality, maintenance of operational readiness of objects of power supply system, ensuring parallel work with other power supply systems.

Static stability of power supply system - capability of power supply system to return to the set mode, initial or close to it, after small indignations. Small indignation of the mode of power supply system is understood as such indignation in case of which changes of parameters are incommensurably small in comparison with values of these parameters.

The Emergency Situation (ES) - situation in case of which there is high probability of violation or normal living conditions and activities of people are already violated, connected with accident, catastrophic crash, natural or ecological disaster, epidemic, application possible modern weapons of destruction and brought or able to lead to human and material losses.

Power network - the set of substations, distributing devices and the power lines connecting them intended for transfer and distribution of electrical energy.
