Application Projects Experience
ACS 880 with direct torque control functions and energy saving functions as well as four-quadrant Energy regeneration and feedback function, with in-built filter and reactors, very good performance, mainly application for the field of Steels, Cement, Chemical, Oil & Gas, Power, Polymer & Rubber, Pulp & Paper, Sugar, Minerals & Mining.
Metallurgy Project Experience
The converter steelmaking process of Henan Yaxin Iron and Steel Plant's steelmaking plant is relatively complex, with many detection parameters and frequent equipment movements. The accuracy of process parameter detection and the level of automatic control are directly related to the quality and output of molten steel.
Converter Requirements for the AC VFD Control System:
- The mechanical tilting converter can continuously rotate 360°, driven by 4 sets of 90KW variable frequency motors
- Maximum safety and reliability during operation
- Good flexibility to buffer shock load and torsional vibration
Solutions:
Since these 4 motors are rigidly connected, the speeds of all motors are required to be absolutely synchronized, so the transmission of the 4 motors adopts master/slave control, and the data is transmitted between the 4 drives through internal communication.
FAQ
What is direct torque control?
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
What is the benefit of direct torque control?
- Torque and flux can be changed very fast by changing the references
- High efficiency & low losses - switching losses are minimized
- The step response has no overshoot
- No dynamic coordinate transforms are needed
- No separate modulator is needed
- There are no PI current controllers
- The switching frequency of the transistors is not constant
- Due to the hysteresis control the switching process is random by nature
- The intermediate DC circuit's voltage variation is automatically taken into account
- Synchronization to rotating machine is straightforward due to the fast control
What Type Of Motor Is Compatible With Inverters?
Inverter motor type must be a three phase AC induction motor. Preferably, you should use an inverter-grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class inverters.
What Are Some Of The Common Reasons Why Motors Fail?
The EPRI Power Industry Study by General Electric in 1985 offered the following causes based on 6,000 utility motor failures: 41% were bearing related, 37% were stator related, 10% were rotor related and 12% were other causes.
