Requirements for the counters of electric power



To measure the power and presentation of the results of measurements should be used multifunctional electronic electricity meters of accuracy class 0,2S, 1 (2) A.

Interfaces counters must be protected against overloads using special protective devices.

The ACSEE should be implemented redundancy of information channels of communication with meters, for which electricity meters must be equipped with two independent interfaces.

Cable news channel of communication should be routed separately from the current-carrying conductor along the shortest path.

It must be provided for mounting the cable news channel in the vicinity of the attachment.

 

 

The requirements for communication cabinet ACSEE SS

Cabinet Communications ACSEE SS is designed for equipment that performs the functions of receiving, storing and processing information, which comes from the electricity meters.

The cabinet must be installed on the floor and equipped with a fan unit with thermostat.

The cabinet must be capable of placing the server and communication equipment ACSEE and have space to accommodate additional or backup equipment in the amount of not less than 30% of the total.

The cabinet must be installed in the room where the equipment will be located server ACS substation. No direct exposure to sunlight on the cabinet and its installation near the heating system (the distance from the heating system is not less than 1 m.)

Communication equipment ACSEE, which is placed in the cabinet, with the electricity meters should be cable type 5e SFTP.

Cables of information channels, which are routed to the cabinet must have a reserve of length 2 m for installation inside the cabinet and processing all conductors.

 

Features server hardware:

 

· As server should be used industrial computers increased reliability c possibility of creating RAID- array. As part of the server must have two power supply and at least two network cards. Hard disk drives and power supplies must support the ability to "hot swap" function (Hot swap). We recommend using a server with extended operating temperature range (greater than 25 ° C.) For the premises where they will be used.

· construction of servers must allow their placement in special racks, cabinets floor mounting;

· the server must be designed for continuous operation. Disable the server is allowed during routine maintenance;

· general and application server software must allow the simultaneous operation of all communication ports.

 

 

The requirements for AWP

ACSEE SS should be composed of two AWP. AWP must include a PC, software and guidance documents, and be designed to account for power management and monitoring system.

AWP must connect to the communications closet ACSEE via a local area network. Position determined at the project (P).

 

For information exchange between system components to be used the following means of Telecommunications:

 

· Ethernet (between the cabinet and the media server ACSEE and AWP);

· physical link.

 

 

The requirements for communication channels

Channels of communication must ensure reliable transmission of data from the meters to the means of communication and telecommunication systems.

Channels of communication with SS regional level should have a permanent capacity of not less than 64 kbit / s, with a safety factor of at least 0.9 channel.

The requirements for the interface hardware and cables to connect to the server counters ACSEE:

 

· provide information communication with metering devices, ACSEE server, AWP.

· should not change the data format in the conversion of physical parameters into signals which are transmitted;

· must be designed for continuous operation and does not require tuning and adjustment during operation;

· connecting cables must provide for the transfer of data without distortion with a minimum decrease in the level of the signal on the path from the source to the transceiver;

· cables that are connected to the instrument should not be mechanically affect their terminal clamps;

· the connection between the equipment must be carried out continuously stub. In any case, the connecting equipment must not introduce distortion into the signal, which is transmitted;

· Do not use the same cable lived on the primary and backup hardware acquisition.

 

Technical equipment must be located in compliance with the requirements contained in the technical and operational documentation in order to ensure ease of use in the operation of the system and perform maintenance.

Enable or disable certain hardware, power outage should not lead to failure of the system hardware. In case of refusal of technical means shall be provided in registration failure.

Each of the system hardware must accept its replacement by means of functionally similar specified without any design changes and / or regulation in other technical means (except as specifically provided in the technical documentation on the system).

 

 

Requirements for metrological support

 

Measuring instruments should be made to the "State Register of measuring devices approved for use in Ukraine in Ukraine".

The metrological characteristics of the measuring instruments, which are used in the system must be listed in the documentation on the specific types of funds.

Forms of metrological supervision measuring instruments, the organization and procedure of checking and metrological certification must meet the requirements of regulatory documents.

In accordance with the principles of the system of construction of ACSEE all test operations associated with the formation of the measuring data are made a part of the measurement. The second part of the ACSEE- SOD measurement operation is performed. In the course of its operation it receives from the measurement of the primary data and processes them, error results are determined solely by the primary data errors. Measurement of the ACSEE performs the function of a complete measurement and has metrological characteristics which are normalized.

In carrying out metrological certification of metrological research is subject to the functional part of ACSEE accounting items, which ensures the formation of the primary database.

 

Requirements for Organizational Support

 

ACSEE SS should not require daily maintenance on the part of engineers and technicians in computer science and programming. This condition shall be ensured through the use of the development and operation of ACSEE SS appropriate equipment, software, technology, backup hardware and software, remote administration software.

The list of equipment subject to periodic maintenance is determined at the stage of the project (P). Full list of features (assignment to them of units and personnel management ES,MES and substations) with respect to the operation and maintenance of ACSEE SS should be worked in the design of the ACSEE SS and entered in the relevant documents on the organizational support to ACSEE entry into force. The current operation ACSEE SS entrust the duty personnel substation, line maintenance ACSEE - Staff MES.

 

 

Requirements to ACSSE

The system is designed to ACSSE:

· continuous monitoring of power quality;

· freeze output values ​​of the power quality of tolerance;

· communication with substation automation systems for reporting abuse of power quality;

· communicate with the ACSEE SS to generate quality labels;

· archives;

The system should measure, calculate and record all quality parameters of electric energy in certain GOST13109-97.
