Technical base SHC - universal technical means of  automation ТУУ 33.3-33675000-001:2010, of new generation on the basis of the latest achievements of electronics and information technology. The equipment supplied by our company has high reliability and high exploitation characteristics. Our products are not inferior to technical characteristics similar samples of product, manufactured by the world's leading manufacturers. The main scopes of application arepower-generating units of power plants and power stations.

During the development of IAS and the SHC the fundamental principles of security (protection against common cause failures, redundancy, compliance with the principle of independence, technical diagnostics, etc.) and current requirements in Ukraine and international regulations on nuclear power plant safety are observed.

SHC have the following data and operational advantages:

  • unity of software and technical means for performing all functions, standardization of equipment;
  • simplicity and clarity of design, ease of operation and simplified maintenance procedure;
  • increased availability and reliability due to redundancy and continuous automatic system of diagnostics and control ofhardware and software;
  • high precision characteristics;
  • a small range of technical means;
  • redundancy of elements, the failure of which could lead to common cause failures;
  • implementation of protection against faulty actions of personnel;
  • availability of information data, convenient operator interface;
  • ease of making changes, additions and reserve of computing resources forability of extension.

Technical and software SCH means can create Automatic Process Control Systems, open for the modernization and development without necessity to change the previously implemented solutions.

National and international experience of creation and operation of Automatic Process Control Systems is taken into account in the project engineering. Project engineering is carried out with the use of certified software tool SINTAR, which enables to carry out a refinement and testing of software on PC-compatible computers, and quickly make and work out 

necessary changes in the software during the process of equipment exploitation.The requirements that are aimed atimproving the consumer characteristics of PTC, the reduction of the development and implementation of process control systems and improving their level of service are implemented.

SHC provide the ability to create single and multi-level hierarchical systems of distributed control and centralized control, which correspond with the structure of the technological object and the way of its management. 

Hardware tools and software of SHC have modular structure and advanced system software, allowing a wide range of uses, from local subsystems of management and control to full automation of industrial facilities.

Unified automation means of limited range with a lifetime of 15 to 30 years are used in SHC, technical solutions, which give the opportunity to replace failed or obsolete SHC technical equipment with the same type of equipment without any change or alteration of basic constructs included in SHC and with minimal changes in software are implemented.

PTC provides the following key functions:

  • automatic regulation of process parameters;
  • control of process parameters;
  • automatic control of the turbine;
  • control of mechanical quantities of the turbine and generator;
  • automated software logic control of starting and stopping;
  • remote management of actuating mechanism;
  • process protections;
  • process interlocks;
  • warnings and alarms;
  • reproduction of analog signals for adjacent systems;
  • indication of the state of the SHC , sensors and actuating mechanismby means of unit switchboard;
  • preparation and transmission of information on the state of the SHC, sensors and actuating mechanismto the block process control system.

Additional features of SHC:

  • technical diagnostics, including:
    automatic check the of SHC status after power-up and continuous check during operation;
    control of  components performance, working order of internal and external links, the correctness of data transmission over digital carrier lines;
    continuous monitoring of power, temperature, smoke and insulation resistance inside SHC cabinets, absence program hang-up, reliability of input signals and digital data;
    self-diagnosis (self-control)  of software tools;
  • formation and delivery of data about  discovered  original events, teams of protective actions, their prohibition or turning-off;
  • storage of data in the operational, daily and long-term archives, display of current and archive information on monitors of computer stations and its registration in the form of reports;
  • interactive installation management systems characteristics.

Implementation of management and control systems, manufactured by our company, will provide a safe and efficient operation of the equipment, including the optimal operational conditions, a significant reduction of erroneous actions of personnel and forced outage of the equipment, power quality and stability of the power units.

Software takes into account the requirements of international standards and meets the following principles:

  • modular construction of all components;
  • hierarchy of own software and data;
  • efficiency (minimal overheadsfor creating and maintaining of software);
  • easy integration (possibility of extension and modification);
  • flexibility (the ability to make changes and realignment);
  • reliability (according to the given algorithm, lack of false actions, protected from unauthorized access, implementation of algorithmsin the scheme of regular code of weavings);
  • fail safe (carrying out of functions in the whole range or partially of atfaults and failures, disaster recovery);
  • unification of decision-making;
  • simplicity and clarity of content, structure and program source code;
  • fulfillment of the requirements for the limited use of the software, including the interrupt handling;
  • distributionof function at different levels;
  • work of operation system software  in protected mode of memory;
  • work of software with the hard tact on the same branches;
  • limiting of cyclic programs of functional software;
  • degradation of software by disconnecting the failed programs.

The use of proven algorithmic and mathematical solutions inSHC helped to ensure stable operation of power-generating units.
