Application projects exerence

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. To this end, there must be a set of control systems with accurate and timely detection and high level of automatic control in order to stabilize production and meet the needs of enterprise survival and development.

Converter requirements for the AC VFD control system:

(1) The mechanical tilting converter can continuously rotate 360°, driven by 4 sets of 90KW variable frequency motors, and can stop at any position accurately. It should also have speed regulation performance according to process requirements. Its tilting position can have certain interlocking requirements with related equipment such as oxygen lance, ladle car and fume hood; (2) In the process of operation, there must be maximum safety and reliability. When a certain part of the electrical or mechanical failure occurs, the tilting machine should be able to continue to operate for a short time and maintain it until the end of the first steelmaking furnace. (3) The tilting machine should have good flexibility to buffer shock load and torsional vibration generated by starting and braking

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. The inverter is used as the host, which adjusts the speed and sets the output torque. Other inverters, as slaves, follow the torque response of the host, and completely solve the "nodding" and "shaking" problem caused by the asynchronous operation of the motor.

National key project - Xiangyanghong scientific research ship>=10000m main cable winch drive control

This project is a high-end marine long-line winch,world leading level. Due to the large number of precision electronic equipment used in marine detection, in order to prevent the electromagnetic interference of the equipment and ensure the work of the whole ship, strict requirements are placed on the drive system of the winch, and the expected harmonics are less than 3%.

Traditional frequency converters cannot meet the high-precision coordination of multi-machine torque at this site and extremely low harmonics (conduction and radiation), and the storage system has been occupied by foreign systems. It has undergone multiple rounds of screening through rigorous schemes and technical strengths, and is also based on the experience of independent and controllable excellent drive schemes. , choose INOMAX after fully considering performance indicators, reliability, maintainability, etc.

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 because the transistors are switched only when it is needed to keep torque and flux within their hysteresis bands
* The step response has no overshoot
* No dynamic coordinate transforms are needed, all calculations are done in stationary coordinate system
* No separate modulator is needed, the hysteresis control defines the switch control signals directly
* There are no PI current controllers. Thus no tuning of the control is required
* The switching frequency of the transistors is not constant. However, by controlling the width of the tolerance bands the
average switching frequency can be kept roughly at its reference value. This also keeps the current and torque ripple small.Thus the torque and current ripple are of the same magnitude as with vector controlled drives with the same switching frequency.
* Due to the hysteresis control the switching process is random by nature. Thus there are no peaks in the current spectrum. This further means that the audible noise of the machine is low
* The intermediate DC circuit's voltage variation is automatically taken into account in the algorithm (in voltage integration).Thus no problems exist due to dc voltage ripple (aliasing) or dc voltage transients
* Synchronization to rotating machine is straightforward due to the fast control; Just make the torque reference zero and start the inverter. The flux will be identified by the first current pulse
* Digital control equipment has to be very fast in order to be able to prevent the flux and torque from deviating far from the
tolerance bands. Typically the control algorithm has to be performed with 10 - 30 microseconds or shorter intervals. However, the amount of calculations required is small due to the simplicity of the algorithm
* The current measuring devices have to be high quality ones without noise because spikes in the measured signals easily cause erroneous control actions. Further complication is that no low-pass filtering can be used to remove noise because filtering causes delays in the resulting actual values that ruins the hysteresis control
* The stator voltage measurements should have as low offset error as possible in order to keep the flux estimation error down. For this reason the stator voltages are usually estimated from the measured DC intermediate circuit voltage and the transistor control signals
* In higher speeds the method is not sensitive to any motor parameters. However, at low speeds the error in stator resistance used in stator flux estimation becomes critical

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. For motor size, in practice it is much better to find the right size motor for your application; then look for an inverter to match the motor.

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.
