Technical characteristic: Main technical characteristics of АСSЕD: double-circuit control system of technological parameters of boiler unit „S„E„R with internal speed regulation circuit of electric drives of pulverized-coal feeders that uses analog-to-digital speed correction controller, and external circuit formed by automatic controllers operating on „S„E„R with discrete output for feedback formation by technological parameter; - three-circuit control system of technological parameters of boiler unit „S„E„R with internal control circuit by load moment of electric drives of pulverized-coal feeders; - separate group control of electric drives of pulverized-coal feeders with speed correction of with speed correction of each electric drive; - speed difference of each group of electric drives not more than 1%; - operating range of electricdrives speed 10:1; - precise maintenance of electric drive speed in each group uder load moment change not less than 1%; - readiness to operate in ACS of any level.

Advantages over analogues: The proposed ways for modernization of currently operated systems of pulverized-coal feeding of boiler units ТЕС based on new АСSЕD will enable to develop simple, reliable and economical systems of fuel supply, reduce specific fuel (coal dust) consumption, increase maneuverability of boiler units, reduce service and repair costs for electrical equipment of boilers, increase operating life of main and additional equipment of boiler units.

The development stage readiness: Introduced in production

Description of the development:
()
Boiler units ТЕC operate from energy feedstock consumption (gas, coal dust and other power sources). Development and implementation of modern automation control systems of technological processes can provide reduced power consumption in process of electric and thermal power units production, cyclic-load capability increase etc. Boiler units ТЕC operate on coal dust. They consist of technological complexes of pulverized-coal feeding that provide coal dust supply to fire-chamber. In the Institute of Electrodynamics of National Academy of Sciences automation control system of electric drives of pulverized-coal feeders (АСSЕD) was developed. It allows to save energy feedstock (coal) consumption for 1-3%. Pulverized-coal feeders АСSЕD were put into operation on boilers БКЗ-210-140 and БКЗ-220-100Hz by research workers of science-and-technical company "ТЕМS" (Kyiv). They showed high operating efficiency in coal supply control. Boilers are now widely used, S" performs their service maintenance. For their entation the Institute of Electrodynamics of Academy of Sciences and company "ТЕМS" orks on development of new control algorithms ed-coal feeding technological processes as well ograms and software for their implementation.
