Design Of Power Control Systems And Control Procedures

The control system realizes the automatic control of the spot equipments, control software is result that commanding center to control the system, the control be decided by to control the software primarily. The control system realizes the automatic control of the spot equipments, control software is result that commanding center to control the system, the control be decided by to control the software primarily.This text aims at the shortage of No.4 blast furnace in control system in PANZHIHUA iron & steel (Group) Corp, replacing the Japanese appropriation control system with the general use control system. Research the target primarily: the generator start process speed control, and synchronization control, the generator rising load control, the generator reducing load control, the generator reducing speed control, and the generator purge control etc. The aim Control finally that the No.4 blast furnace top pressure in PANZHIHUA iron & steel (Group)Corp control within the scope of±2 kPa.For guaranteeing whole control system successful running , and can run the best control result in a short time , attains above aims, proceeded all analog signal of the original control system and record they, and contrast control output between the new system and the old system, and the control software on new control system is proceeded perfectly, the control software be proceeded off-line again and again , verified the control software accuracy.
