When developing technical solutions for the construction of VOLP, the general principles for the construction of the Unified Electric Power Communications Network (ESSE) were taken into account.

2. analysis of existing energy communication networks in the construction region with 220 kV of energy.

PS 220 kV Vladimirovka, located in Akhtubinsk, Astrakhan region. The existing communication network is built on the basis of the organization of management and operation of PS Vladimirovka Volga-Donskoy PMES FOAO FGC UES.

Means of communication at the 220 kV Vladimirovka PS provide operational diplomatic communication of this energy facility.

Internal communication of PS 220 kV Vladimirovka is absent.

At the substation, the TM512 telemechanics device, mo-dem TgFm2/1 and the EDTS66 control switch for 30 numbers are installed.

The telephone network of the Volga-Don PMES is built on the basis of the digital telephone exchange Meridian-1 (manufactured by NORTEL Telekom, Austria). All PBXs are connected to each other by connecting lines of various types (or by digital flows E1 - by RRL or OLS; or 4-wire tones - HF communication via power lines; or by cables - by sealing method or by physical copper vapors.

1. In the Office of VDPMES (central communication node, Volgograd), 61 options of the above-mentioned PBX with a capacity of 240 numbers are installed. Internal numbering from 2300 to 2540. Of these, 200 numbers (2300 to 2499) have access to the public communication network (PSTN) with assigned city numbering from 742300 to 742499. For the signal transmission medium, the VOLS up to GATS72/74 is used, which passes in the city cable sewage system. The optical locator system is compressed by the HSA25 transmission system (4x2Mbit/s). GATS 72/74 communication protocol - EDSS1, channel synchronization - from GATS. The PBX has a guaranteed power supply for about two hours.

2. The 11 option of the Meridian-1 PBX with a capacity of 208 numbers is installed on the PSHAS "Balashovskaya" (r.p. Novonikolaevsky, Volgograd Region). Internal numbering 3000 to 3199 and 3901 to 3908. Of these, 200 numbers (from 3000 to 3099 and from 3100 to 3199) have access to PSTN with assigned city numbering from 67500 to 67599 and from 67300 to 67399. For the environment of signaling the communication line (KSPP4h1h1.2 type) to PATC6 of genitive is used. New Nikolaev. The communication line is condensed with the system of OGM30 broadcast (1x2Mbit/s). Communication protocol with GATS 72/74 - EDSS1, channel synchronization - from PATS. The PBX has a guaranteed power supply for about two hours.

3. At the 500kV Volga, Trubnaya, Frolovskaya, Yuzhnaya, Astrakhan substations, 11 options of the Meridian-1 PBX with a capacity of 48 numbers were installed. Internal numbering 32xx (Volga), 33xx (Trubnaya), 34xx (Frolovskaya), 35xx (South), 3xx (Astrakhan). There is no direct output to local PSTN data of PBX. Communication with the PSTN is carried out through direct city numbers from the GATS (RTS) through a 2-wire connection. All PBXs have guaranteed power for about two hours.

4. At 220kV substations located in the service area of ​ ​ the Volga-Don PMES (22 PS in the Volgograd region and 10 PS in the Astrakhan region), telephone exchanges are almost nowhere installed. On the same substations where PBXs are available (ATSK50/200), there are no exits to the PSTN from them. Communication with PSTN is carried out directly from the city telephones installed at the dispatcher and/or in other departments.

3. fibre-optic transmission line.

During the reconstruction of IR Vladimirovka, the construction of a fibre-optic transmission line (FBL) using a self-supporting fibre-optic cable (VOC) along the VL is planned, along the following route :

- from PS 220 kV Vladimirovka - Trubnaya by VL 220 kV Vladimirovka2 (133.1 km).

The total length of the VOLP is 133.1 km.

Throughout OLP, it is proposed to use a self-supporting VOC (OXN) with a number of fibers of 24 (8 fibers - according to the recommendation of MCET G.655, 16 fibers - according to the recommendation of MCET G.652).

Calculation of attenuation of OLP sections is made according to the formula:

A = Ap x L + N x Am + 2 x Ak + Azap,

where:

A (dB) - attenuation in the area "from connector to connector";

Ap (dB/km) - linear attenuation in fiber. For fibers used in trunk cables, 0.22 dB/km for a wavelength of 1550 nm;

L (km) - length of VOC in the amplifying section;

N - number of pass-through couplings in the MCF section;

Am (dB) - maximum permissible attenuation in pass-through couplings at places of fibre welding of two cables is assumed to be equal to 0.05 dB;

Ak (dB) - attenuation in terminal crosses and connectors of terminal cords is accepted equal to 0.5 dB;

Azap (dB) - process attenuation margin equal to 3 dB.

4. digital information transmission system.

In accordance with the specifications of the Center's MEAs, based on the solved tasks and the OLP information load, taking into account the predicted volume of communication channels for the future, it is proposed to organize a high-speed digital information transmission system (CSPI) of the STM1 transport level on the 220 kV Vladimirovka - PS 220 kV Trubnaya section of the PS. The CSPI was developed taking into account the transfer of technological information, information of the automated process control system (APCS), the automated system for accounting and control of electricity consumption (ASKUE), corporate information of FGC UES OJSC and RAO UES of Russia. Access to the US OJSC "Southern Telecommunications Company" is decided by including the PS Vladimirovka in the already existing VOLS system of the Volga-Don PMES. Hardware construction of CSID is defined by the following tasks:

Operational display, selector and loudspeaker radio communication system;

Audio recorder for recording dispatch conversations;

A complex of intra-object communication cables, including a structured cable system (SCS) in the OMP building.

8. organization of line-operation communication for servicing oats of 220 sq.

Operational-visiting brigades going for preventive and repair restoration work are provided with permanent radio communication in the VHF range (in case the object is in the reach of the radio network). Communication can be both simplex and duplex. Stationary, mobile and wearable radio stations are proposed for the organization of linear-operational communication.

Radio stations of various manufacturers have additional capabilities:

- automatic answer to the call;

- installation of speech masker;

- automatic scanning;

- pre-dialing of subscriber numbers;

- installation of boards for operation in trunking systems;

- implementation of the military standard MIL810/C/D/E.

If necessary, the possibility of acquiring satellite communication terminals and cellular telephones is being considered for the organization of LES.

VHF radio communication is organized as follows:

On the territory of the substation, at the maximum possible distance (but at least 30 meters) from the switching and power equipment, a tower 30 meters high with transceiver antennas installed on it is located.

In the room or in the thermoboxing having volume not less than 0.5 cubic meters with the heater, the fan and the thermorelay the transceiver with the operating module of remote control, the block of power supply of stationary radio station is placed.

The authorized dispatcher or other responsible personnel, using a fixed or wearable radio station, shall communicate with the foreman (or any of the members of the brigade) who is in a car equipped with a radio station or has a wearable radio station, using a DTMF tone set (each radio station has its own code) or pronouncing special call signs on the air. These call signs are assigned to each radio station at its registration (obtaining permission to operate) and are communicated to the user each time the radio station is issued.

Radio communication can also be used for communication within the brigade (foreman - with members of the brigade; brigade members - among themselves).

Estimated range of radio communication is estimated by empirical formula D (km) = 4.12x, where h1 is height of transmitting antenna suspension in meters; h2 is the height of the receiving antenna suspension in meters. Taking into account the height of the antenna suspension of the stationary radio station equal to 31m and the car 2m, the range of confident reception is up to 30km.

Uninterruptible power supply (UPS) is designed to perform a number of functions related to the power supply of telecommunication equipment and should provide:

reliable redundancy of power supply of all designed, as well as existing equipment in case of failures of the auxiliary network of the facility in accordance with the requirements on the part of consumers of group A, which do not allow interruption of supply voltage ~ 220V;

"hot" replacement of battery modules and other main UPS units without interruptions in power supply to consumers.

In case of loss of AC external mains voltage, UPS shall provide continuous operation time of all connected equipment for at least 2 hours.

UPS shall have a control and alarm panel, which allows to receive information about the system status, as well as to conduct remote monitoring.

DSPI equipment shall be supplied from DC source with grounded plus and rated voltage 48V at changes in the range from 38.4 to 56.6V.

UPS shall be designed for operation from AC source with voltage of 380/220V +/- 20%, frequency of 50 Hz (from 47.5 to 51.0) and with non-linear distortion factor of not more than 10%.

In all cases of underestimation or loss of voltage of the primary source, the system must restore the specified parameters after the appearance of voltage without personnel intervention.
