2. Feature Requirements acsee ss

   1. Functions and settings tasks acsee ss

ACSEE SS must implement the following basic functions:

• measuring the required electrical parameters;

• formation of schedules flows of active and reactive power with the integration period set in the counter, or a multiple of it;

• creation and storage within a specified time of the primary database for the distribution of electric energy;

• automatic reading at a given time of day or at a specified interval data from the meters and make a copy of the primary database counters;

• primary processing and control of completeness of the information;

• formation of the necessary information on points of accounting, taking into account a possible switch connections and replacement of meters;

• calculation of generalizing and group settings;

• fixing the meter readings for 00 hours, the estimated time;

• the validation of information to form a sign of quality (calculation and monitoring of imbalances in the electricity substation buses, verification of information provided by the main and back-counters);

• development of balances SS stored values ​​counters to 00 hours;

• Identification and storage with fixing the date and time of occurrence of events related to changes in the external non-standard (power failure, lack of communications, unauthorized access) and internal (operational error, data corruption, exceptions in data processing) hardware and software environment means. Data changed its quality under the influence of such events should be marked appropriately sign;

• adjustments of timers counters System server time;

• provide automatic switching to summer / winter time;

• conducting routine switching spreadsheet;

• provide manual data entry into the system and manually (with help an work operation position) data collection from meters. All data that is entered by hand, must have a indication of the quality (reliability) of data "Manual input";

• formation of screens and graphics output parameter records (in the form of screen and report forms) to the terminal and / or a printing device at the request of the operator with AWP ACSEE;

• reporting;

• export copies safety regulations;

• interaction with ACS substation;

• interaction with ACSSE;

• automatic control and diagnostics of the technical state of the accounting system of electric power, technical means and channels of communication system, automatic notification of operating personnel in the event of hardware failures and communication channels;

• reference and protocol analysis work documenting access to server information ACSEE, identification and storage with fixing the date and time of occurrence of all the events associated with non-standard changes in the external (power failure, lack of connection attempts to unauthorized access) and internal (operational error, a violation of the integrity of data exceptions in data processing) software environment and hardware;

• maintenance of reference data;

• data storage in case of accidents, data backup, archiving data to external media;

• protect information from unauthorized access and influence;

• provide users with context-sensitive help;

• maintaining a single system time, the methods of automatic and manual synchronization of the internal clock of all components ACSEE SS (including timers, electricity meters) at the time of the reference time. ACSEE SS should get the exact time from the level of the power system.

The electricity metering points, which are installed electricity meters that measure energy in both directions, as well as on groups of records, which include these points account must be taken into account at the same time released and adopted active and reactive energy.

Averaging interval (a system-wide parameter) must be selected from a number of 30 to 60 minutes. This parameter is set in the system configuration according to customer requirements and can be changed in the future by the customer.

The parameters of electric power metering must be recorded in the next accounting periods at the time of the event (with the I / O power lines), which took place between the time set commit readings of electricity meters:

• hour (half-hour);

• change;

• day;

• decade;

• month;

• neighborhood;

• year;

• any period (previous times);

• integral total (equivalent meter readings at the end of every day, every month and at the time of the last survey).

Accounting manual data entry must be provided by the points that are not equipped with automatic data collection and the point to which the connection is not available.

Parameters of account must be with the mark of time, sign of authenticity and sign which determines the mode of entry of the indicated data in the system (hand or automatic). The system must provide archiving and storage of basic data in an untilled kind.

ACSEE SS must provide the conclusion of parameters of account, which are kept on the server ACSEE, as the CRT and current forms on a terminal and/or on the device of seal in demand of operator of AWP ACSEE.

ACSEE SS must provide automatic diagnostics of next failures and refuses of hardwares and ductings of connection of the system:

• absence of access to the server of ACSEE from the side AWP;

• lack of communication between the server ACSEE with counter;

• deviation of the time counter on the system in excess of the values ​​specified in the tolerance;

• availability of system errors and other counter.

Diagnostic messages are displayed in the AWP ACSEE as the corresponding screens (the current state of the system, log messages, and others.) And accumulate in the server ACSEE (with a shelf life that is set in the System Setup).

ACSEE SS should provide the ability to configure an operator who has the proper credentials, the following system configuration settings:

• a list of attributes and system users (login name, password, description, access level);

• a list of parameters of metering points (the name of the point of registration, serial number and the communication counter values ​​of energy conversion factors);

• the composition of the list and account groups;

• the date and time daylight savings and standard time;

• parameters of the communication ports collection server;

• long-term preservation of information in the server ACSEE (for different types of parameters).
