• boiler's control while burning natural gas, fuel and masut;
• emergency boiler stop when trigged by technological protection;
• overload protection;
• technological protection performing local operations;
• auxiliary equipment mechanisms block;
• block of burner, as at the working boiler and during kindling;
• automated technological protection and blocking turn on and turn off;
• bringing boiler to set parameters;
• technological parameters regulation;
• cyclic acquisition of all technological parameters;
• cyclic acquisition and control of discrete signals in accordance with set algorithm;
• warning and emergency sound and light signaling;
• warning in case of deviation or malfunction of equipment;
• diagnosis of control system and boiler equipment;

Furthermore, the system provides functions inherent in the power plant automation:
• technical and economic analyzes conducting;
• reports compilation;
• information archiving.
Power block’s SCADA implementation based on IndustrialIT System 800xA allows to fulfill UCTE requirements:
• automated block load-shedding from any capacities to the level of own needs;
• regulation systems insensitivity less than +/- 10 MHz;
• frequency adjustment in the system of power regulation within ΔP(Δf)=0..+/-5% rated power;
• adjustable statistizm within s=2…8%;
• adjustable dead area of frequency regulator Δf=0...+/-500 MHz;
• ability to synchronize with the network within 48,0 Hz to 51,5 Hz.
• old control panels, measurement toolbars, control cabinets, terminal cabinets and cables are deinstalled;
• microprocessor system devices are set;
• office interior is optimized;
• up to 100 % of temperature transmitters, pressure transducers and differential pressure transducers are replaced;
• electric contact manometers and thermometers are replaced for more secure solutions equipped with pressure transducers and temperature transmitters;
• additional measuring circuits are put into operation according to requirements of technological systems modernization;
• multiple measuring circuits are created in accordance with requirements to majorized protection systems for power generating units;
• all the server generators, working at the regulating circuits, are replaced or fixed;
• all the object signal cables as well as MCR cables are replaced.
New automation system based on IndustrialIT System 800xA has the following advantages:
• distributed operation control structure, due to which interferences and damages limited to one technological device;
• high reliability of equipment and software;
• equipment uniformity (same modules can be applied at the measurement units and control units);
• optimal structure of technological protection system with “2 and 3” logic in terms of reliability;
• software performing auto diagnosis and testing, supporting engineering;
• variety of information display: graphs, schemes, diagrams and so on;
• ability to register and archive events, reports and to account technical economic parameters.
