  • Transcript

    • 1. Presented by Industrial Drives Bazaar YantraBazaar.com http://yantrabazaar.com [email_address] AC Drives System http://yantrabazaar.com
    • 2. Why Variable Speed control
      • To full fill the requirement of process
      • Requirements of Different process-
      • Material Treatment
      • Material Transport
      http://yantrabazaar.com
    • 3. Applications
      • Industrial Segments – Chemical Industries, Power Plants, Metal & Mining, Pulp, Paper and Printing, machines shops, Plastics & Textiles
      • Non-Industrial Segments – HVAC, Water treatments
      http://yantrabazaar.com
    • 4. Non Industrial Segments
      • An opportunity for VSD
      • Air conditioning a part of HVAC –
      • Air flow requirements change according to the humidity and temperature of the room
      • Adjustments is done by knowing the supply and return air flow
      http://yantrabazaar.com
    • 5. Industrial Segments
      • Each process need the material and energy supplied to accomplished the required process
      • Waste in the form of energy and material is also produced in every process
      • Application of VSD - To control the mechanical power of different machines involved in the process
      http://yantrabazaar.com
    • 6. Material Treatments
      • To alter the material’s properties into other form
      • VSD for well defined shapes – paper, metal, wood. The treatment is done by paper machines, rolling mills, saw mills
      • VSD for indefinite shapes- various food products, plastics etc. The treatment is done by stirrers, extruders, centrifuges
      http://yantrabazaar.com
    • 7. Transportations
      • Consists of conveying, dosing and pressure changing apparatus.
      • Types of Materials –
      • Solid e.g.- wood, metal, minerals, shipping containers done by conveyer, elevator, cranes
      • Liquid- water, oil, liquid chemicals done by pumps
      • Gaseous materials- Air done by Fans, compressors or blowers. Applicable in Air conditioning
      http://yantrabazaar.com
    • 8. Electric Motors drive most machines in Industrial process http://yantrabazaar.com
    • 9. Little about Motor Applications
      • All loads moved by electric motor is moved by magnetism.
      • Purpose of every component in motor is to use harness, control and magnet force.
      • To move a load fast, you need to move magnet faster.
      • To move a heavier load or to move load faster you need more magnet (torque)
      • Applying an AC Drives means u r actually applying magnets to move a load
      • Where does the real action happens in AC Drives System ?
      http://yantrabazaar.com
    • 10. What happens when we apply an electric current to motor
      • The magnetic field grows at a finite rate to a finite size
      • After voltage is applied and full current is reached, the field quits growing and the size will be constant
      • If the applied voltage will be increased, the fields will grow and will be more stronger. Field will be weaker and will shrink if the applied voltage will be decreased.
      • The more current coil will consume, the more stronger and larger the magnetic field will be.
      • when electric power is removed from the coil, the field doesn’t just disappear. It decrease its size until it disappear.
      • When we increase voltage to our electro-magnet, current will increase directly proportional up to a point. After that point current increases exponentially.

    • 11. Energy Losses
      • Some energy is consumed by simply magnetizing the iron core
      • Some energy is converted into heat within the iron core
      • Once a core is magnetized, demagnetization and reverse polarity re-magnetization consumes more energy and takes quite a long time The amount of this loss is proportional to the frequency of polarization reversals.
      • This happens 120 times per second when operating an AC motor at 60 hertz.
      • Reducing losses not only saves energy directly but can also reduce cooling load on a facility's air conditioning system.

    • 13. What is an AC Drives System
      • Integral Configuration, Devices used, Switching, Control Technology and Motor Protections
      http://yantrabazaar.com
    • 14. Control Technology in Drives
      • V/F or scalar Control using PWM
      • Sensor less Vector Control
      • DTC Control
      • Fuzzy Control
      • Neuro- Fuzzy Control
      http://yantrabazaar.com
    • 15. V/F Control using PWM
      • Features
      • Control variables are Voltage and Frequency
      • Simulation of AC variable sine wave using Modulator
      • Flux provided with constant V/F ratio
      • Open loop drives
      • Load dictates the torque level
      http://yantrabazaar.com
    • 16. V/F Control using PWM
      • Advantages:
      • Low cost
      • No Feedback required
      • Drawbacks:
      • field orientation not used
      • Motor status ignored
      • Torque is not controlled
      • Delaying Modulator used
      http://yantrabazaar.com
    • 17. Flux Vector control
      • Field oriented control
      • Motor Electrical Characteristics are simulated- motor model
      • Closed loop Drives
      • Torque is controlled indirectly
      http://yantrabazaar.com
    • 18. Flux Vector control
      • Advantages
      • Good Torque response
      • Accurate Speed control
      • Full Torque at zero Speed
      • Drawbacks
      • Feedback is needed
      • Costly
      • Modulator needed
