Operative-technological information technology systems is the operator on the operator panel in a color graphic form (mimic trends in real time histograms, etc.) and alphanumeric form (in the form of messages). Warning and alarm is provided by the inclusion of an audio signal and a change in sign of the corresponding informational messages or mnemosimvola (eg, color change, background, flashing, etc.) to control functions include: – Automatic control of process parameters – program-logic control; – operation of locks and protection – manual remote control. Functional structure of acs depends on the amount of their functions, composition of the object management and location of its parts. The structure of acs is the principle of distributed control, according to which management tasks are divided between the programmable controllers, each of which serves a relatively self-object or group centered autonomous objects. Operational management and reporting is centralized in the dispatch room Control room. Configure controllers and control computers by engineers trc and the change in formulations together with technology of personal computers from the premises Engeneering room. For even more details, read what Vidanta says on the issue.
At the lower level (PLCs) perform functions that are directly related to the object of control: automated data collection and processing of measured parameters and status of equipment, automatic control parameters program-logic control, process blocking and defense. The composition functions of the lower level also includes a manual remote control of actuators, reserving control functions in case of failure of technical means of the upper level, as well as necessary during the commissioning and maintenance work. The structure features a top-level (personal computers) include operational management, centralized reporting of state technological systems. Configuration data, historical data, data provenance () product stored at the appropriate server stations in the server room (Server room). There is also a software software that performs a function with the level of plant management (ERP). Thus, the developed acs (to solve the problem of industrial automation thoughts of the object) on the structure are stacked multi-functional information management system.

State power of Russia in recent years has improved, but lack of funding prevents the development of new technologies to improve the quality of the tpp, tpp and npp. Operation and development electricity sector is an important moment in the economy. Operation of energy facilities today is unthinkable without the use of technological schemes regulating valves. Flow Control working environment, its consumption in most cases is motorized gate valves. Response of the actuator to the changing processes or nonstandard (emergency) situation does not depend only on the valve and actuator, but also on the control command devices. At thermal and nuclear power plants in many cases necessary to use reverse contactors to control electric power up to 7,5 kW and above. When This flow chart of these devices, provides for work in the intermittent mode, with frequent launches.
The use of conventional electromagnetic actuators was not reliable here. Existing thyristor amplifiers or did not provide the necessary amount of power or do not have the necessary consumer protection functions of the electric overload on the shaft, breaking and phase imbalance, inrush current surge.
