4. Requirements to software

The software that is used for the ACS TP operation, configuring and service of its individual systems/subsystems, parts and components shall ensure performing of all functions of mathematical and information support to the full scope.

Software shall be licensed and meet requirement of international and national standards on open systems interconnection. The number and amount of licenses should allow future expansion to 25% in terms of quantity of data to be processed.

The ACS TP software shall meet the following general principles:

• modular architecture of all elements;

• the software hierarchy pattern with providing for “privacy” and “transparency” of data for programs of different levels and priorities;

• efficiency (minimal resources spending);

• flexibility (possibility of incorporating changes and reconfiguration);

• reliability (correspondence to the given algorithm, absence of error operations), protection against unauthorized access to programs and data, protection against destruction of both program and data;

• error resilience;

• unification of solutions;

• possibility of expanding and upgrading;

• ease of use.

The ACS TP software shall include:

• system software being a totality of software tools designed for general arrangement of the computational process;

• network software being a totality of software tools designed to arrange data exchange through the system trunk lines.

• application software being a totality of software tools designed for handling of applied tasks:

  • data collection and process;

  • generating and issuing control commands;

  • data submission;

  • data archiving and documenting;

• Service software

The system software shall include:

• operation system with graphic interface that ensures multitask working mode;

• protection tools for data and programs against software failures and unauthorized access;

• tools for monitoring the system operation and its restore after errors and failures without system stop;

• program loading tools;

• libraries of function for mathematical processing of parameters;

• libraries of interactive graphics and graphic functions;

• tools for managing archives of machine-readable media.

Application software shall ensure performance of functions of:

• display of video frames;

• alarms and events;

• display of the system status parameters;

• archiving of all recorded parameters;

Archiving should provide local and remote access to archived information via standard requests, including from external applications (the presence of the software interface).

• automatic keeping the databases updated;

• documentation and reporting;

• measurement and primary processing of technological parameters;

• Configuration.

All configuration information ACS TP should be structured and stored in a centralized database. In data structuring the standard IEC 61850-7 should be applied.

Service software should include:

• Software tools for backup and recovery of databases and content
