8. Requirements for protection from the influence of external factors

Technical means ACSEE SS when activating and deactivating the switching should not create obstacles that cause a malfunction of other products that are connected to the same network as the primary power supply to the local network, besides a power supply.

The ACSEE SS should include technical measures of protection against the effects of electromagnetic obstacles is provided by laying data cables separate from cables and other purposes, the use of the screening, filtration, grounding. According to EMC elements ACSEE SS shall meet the requirements of international standards IEC 61000-4-8, IEC 61000-4-118 and others.

Protection of the network Ethernet, RS-232 lines, RS-485, Trunk telecommunications, radio links, power lines equipment Surge (interference from lightning strikes, switching of power equipment) must be provided in the construction of ACSEE SS.

When transmitting information through communication channels must be used interfaces and communications protocols that provide interference-encoding, error protection and detection.

9. Requirements for the standardization and unification

ACSEE SS should be based on existing standards, rules, regulations and other regulatory documents ( industry leadership training materials, GOST 34.201-89, RD 50-34.698-90).

In the absence of purchased technical equipment with the necessary characteristics, they should be designed for individual specification for the design phase.

ACSEE unification should be achieved by:

• unification of hardware components through the use of a limited set of standardized hardware, standardized set of events computing;

• unification of the software through the use of standard programs.

The software must be able, without significant improvements of software add-ons, creating interaction between software systems with ACS.

Building ACSEE local level and its integration into the ACSEE regional level should be implemented on the basis of new international standards, namely,:

• ІЕС 61970 (Sim Model - Common Information Model);

• ІЕС 61968 (The main interface for the control of electrical networks, the structure of information messages for control centers);

• ІЕС 61850-7 (forming marks quality parameters);

• ІЕС 60870-6 (data transfer protocols between the control centers) as the primary protocol to communicate with RECS with LECS credentials of the current accounting period, event data and historical data.

• DLMS COSEM (communication protocol)

10. Power Requirements

For electricity meters should be organized external (backup) power supply. The power supply must be carried out using special isolating transformers for electrical isolation of power. Standby power must allow reading of electricity meters in the absence of measured voltage and current.

Electrical equipment in the closet communication server ACSEE, must be single-phase 220V AC, 50 Hz. Power consumption of equipment cabinet ACSEE media server should not exceed 1500 VA.

The housing must be connected to a protective earth circuit.

In order to ensure a reliable power supply cabinet and prevent data loss when a power failure, use an uninterruptible power supply (UPS). UPS, with the disappearance of the primary power supply should provide autonomous operation and shutdown of the server for at least 30 minutes.

Power ARM should be a single-phase AC voltage of 220V, 50 Hz.
