2. Reliability requirements

The system relates to articles of continuous, long-term operation, which require periodic maintenance and repair.

Faults and failures of individual hardware should not lead to an accident and failure of other technical means, as well as the whole system.

Software and hardware systems must ensure storage of all counts and accumulated information failures and failures of certain technical facilities, as well as a loss of power.

Restoring ACSEE SS should be carried out by replacing the units, blocks or components that are out of order, as well as resetting, if necessary, software.

Reliability of ACSEE SS must be provided:

• choice of the optimal functional structure;

• choice of means and the license system and the overall software performance and reliability that meet modern international standards and guarantees enterprise-level;

• prompt replacement of software and hardware that are out of order;

• using duplicate ACSEE SS counters and hardware reserve;

• using effective in terms of the reliability of wiring diagrams and interfaces between system components and processes of collection, processing and transmission of data;

• compatibility of hardware and software;

• the use of modern technologies to develop application software and its testing;

• use of sources of guaranteed continuous (backup) power substation equipment ACSEE and backup power counters.

Reliability ACSEE SS as a whole should be characterized by the following values ​​of reliability indices:

• Average life should be at least:

• 5 years for servers ACSEE \ ACSSE;

• - 3 years for AWP;

• 10 years for other technical means ACSEE SS;

• The average time to failure in the performance of a particular function should be at least 10,000 hours;

• Average renewal time operational status shall be not more than 6 hours (subject to availability of spare parts and relevant software and database files).

Technical means ACSEE substations must provide the following reliability:

• Time availability of software and hardware - should be no more than 60 minutes (with a fully off state to the test of readiness);

• Average shelf life (prior to commissioning) - not less than 9 months.

Resuming performance hardware ACSEE SS should be carried out by replacement (or repair) the technical means (part) from the spare parts, tools.

To ensure the reliability of these indicators should be applied ACSEE substation hardware and software techniques (complete copies of the software, spare parts, components and accessories).

The diagnostic program verify that the hardware and software ACSEE SS must fix violation of proper operation ACSEE.

3. Requirements for Safety

Requirements regarding safety during installation, commissioning and operation ACSEE SS and its components should be presented in the project documentation, and operational documents for specific types of equipment.

Technical means ACSEE substation must comply with electrical and mechanical safety, according to GOST 25861-83 and rules of the safety regulations.

Computer equipment, which are used in servers and AWM must meet the safety requirements of DSTU 4113-2001 and GOST 25861-83.

All external hardware elements ACSEE, which are live must be protected against accidental contact, and themselves have the technical means or protective earth and neutral earthing in accordance with RSEI.

The design of hardware ACSEE SS should ensure protection of personnel against electric shocks and respond to class 01 according to GOST 12.2.007.0-75.

The requirements regarding the safety of current and potential should meet GOST and GOST 12.2.007.3-75 12.2.007.0-75.

Dielectric strength and insulation resistance components ACSEE SS must meet state, interstate and international standards that apply to them, in particular:

• electric power meters - GOST 30206-94 (IEC 687), GOST 30207-94 (IEC 1036-90), State Standard IEC 62053-23: 2012, GOST 6570-96, GOST 30206-94;

• other means of measurement - GOST 22261-94.

Accommodation hardware ACSEE and laying lines of communication should be carried out in accordance with the requirements of normative document "Technical operation of power stations and networks" (GCD 34.20.507-2003), GOST R GOST 12.2.091-94 53769-2010i.

Technical means ACSEE SS must meet the general requirements for fire safety in accordance with GOST 12.1.004-91.

Safety requirements and sanitary requirements for the equipment of workplaces determined by the "Rules of safety in the operation of computers" (approved by public defense work from 10.02.99 №21, registered with the Ministry of Justice of Ukraine on 17.06.99 №382 / 3675).

Incorrect operations personnel ACSEE SS should not lead to an emergency situation.
