Combined Control System for the Coordinates of the Electric Mode in the Electrotechnological Complex “Arc Steel Furnace-Power-Supply Network”

To stabilize the electrical mode of an arc steelmaking furnace in initial stages melting, it is advisable to use a high-speed current-limiting system, addition traditional electrode movement control system. This system implemented by including primary winding transformer choke, controlled thyristors. The such on one hand, reduces negative impact steel power supply network operation and, other, affects built principle impedance regulator. In order analyze mutual influences between systems, mathematical model for and was created. developed can work real time, which corresponds world trends modern synthesis complex technological objects. created model, combined with different approaches formation effect circuit ASF are analyzed.
