Control, monitoring and protection systems

The control, monitoring and protection system is a united information and control system designed for automation of electric energy conversion and distribution. It incorporates digital protection devices, telemechanic equipment, supervisory control systems (SCADA), and an automated energy control and metering system.

The system has a wide functionality and provides:
- protection of the equipment and lines against all kinds of failures and damage;
- automatic control (autoreclosing, underfrequency load shedding, automatic voltage variation, etc.);
- remote control of the main equipment at a power supply object and remote protection setting;
- collection, processing and history recording of analog and digital data about operation of the equipment; 
- generation, automatic updating and archiving of the information database;
- check and diagnostics of the parameters and modes of operation of the equipment;
- energy metering;
- check of the correctness of routine switching;
- display of the substation circuits in real time;
- logging, storing and viewing of emergency and transient processes in the form of oscillograms;
- time synchronization;
- autodiagnostics of the system’s hardware and software.
 
The system is intended to be used at 750/500/330/220/110/35 kW electric power substations and electrical annexes and can be adapted to different types of basic equipment. It is a scalable system which has provisions for integration of other open systems that are already in use at substations, as well as for integration of digital protection terminals of all types available on the market, including equipment of the leading manufacturers such as Siemens, ABB, Areva, General Electric.
Elements of the system can be used to organize data interface between power supply objects included in the dispatch control system.

NIISA’s good engineering capability and experienced personnel allow us to conduct a range of works on creation of control, monitoring and protection systems, including:
- designing;
- manufacturing and supply of equipment and software;
- installation and start-up;
- commissioning;
- warranty and post-warranty service.
