Taigang Air Cooling Island Frequency

Taigang Air Cooling Island Frequency Conversion Unit Project:
 
This project is used in the frequency conversion speed regulation system of the cooling fan that supplies air in Taigang's 40MVA direct air-cooled condensing steam turbine generator unit. All equipment uses public busbars for power supply, and the equipment required in the control cabinet is connected using main busbars, branch busbars and connecting wires. Divided into two sections (each group of 6 frequency conversion cabinets is equipped with a switch cabinet), there are a total of 12 frequency conversion cabinets. The AC frequency conversion cabinet device provided by the complete system is ABB's fully digital AC frequency conversion control device ACS550. The direct air cooling system is controlled in the centralized control room of the unit.
 
It has wide adaptability, namely startup wizard function, adaptive programming, vector control technology, universal interface technology and universal software tools based on selection, debugging and maintenance functions.
