  • 1. EXPERT SYSTEMS AND SOLUTIONS EXPERT GUIDANCE IN POWER SYSTEMS & POWER ELECTRONICS We provide guidance and codesProject Center For Research in Power for the for the following power Electronics and Power Systems systems areas.IEEE 2010 , IEEE 2011 BASED PROJECTS Deregulated Systems, Wind power FOR FINAL YEAR STUDENTS OF B.E Generation and Grid connectionEmail: expertsyssol@gmail.com, Unit commitment, Economic Cell: +919952749533, +918608603634 Dispatch using AI methods www.researchprojects.info Voltage stability, FLC Control OMR, CHENNAI Transformer Fault Identifications IEEE based Projects For SCADA - Power system Automation Final year students of B.E in we provide guidance andEEE, ECE, EIE,CSE codes for the for the followingM.E (Power Systems) power Electronics areas.M.E (Applied Electronics) 1. Three phase inverter and convertersM.E (Power Electronics) 2. Buck Boost ConverterPh.D Electrical and Electronics. 3. Matrix Converter 4. Inverter and converter topologies 5. Fuzzy based control of Electric Drives. 6. Optimal design of Electrical Machines 7. BLDC and SR motor Drives
  • 2. Development of Single Phase Induction Motor Adjustable Speed Control Using AVR Microcontroller 2
  • 3. Principle of Speed Control a F ro n t-e n d b m a in In v e rte r C o n v e rte r aux c AC S in g le -P h a s e DC Busin p u t M o to r 3
  • 4. Block Diagram for Speed Control of Single Phase Induction Motor 4
  • 5. Uncontrolled RectifierRectification: The process of converting the alternating voltages and currents to direct currents.Rectifier: AC to DC.IN4008 diodes are used as in this rectifier 5
  • 6. Circuit Diagram of Uncontrolled Rectifier 6
  • 7. Step Down Chopper CircuitFixed DC Supply to Variable DC Supply 7
  • 8. Chopper ControlControlling the voltage level of the dc Link can be done by changing the PWM signal through the microcontroller.A push button switch is used to increase or decrease the Ton period of a constant frequency pulse. 8
  • 9. PA6 and PA5 are outputs from microcontroller.XOR: High frequency of variable width isgenerated by the microcontroller and the XORgate.Variable width pulse is applied to the gate ofMOSFET through an Opto-coupler 9
  • 10. OptocouplersLED for emitterAir as barrier for isolationPhototransistor for detectorTransformer is similar, but only for ACOptocoupler can be used for DC 10
  • 11. Inverter:Inthis study two power electronics switches ( MOSFET’s) have been used to convert the dc to ac voltage.The frequency is fixed and variable output voltage is obtained by varying the D.C link Voltage by means of the pulse width of the chopper switch. 11
  • 12. Circuit of H Bridge Inverter 12
  • 13. H bridge operation. It can be seen from inverter circuit diagram when T1 and T2 are gated with positive voltage signal, T3 and T4 are OFF by the zero gate voltage signal and vice versa. The four MOSFETs of T1,T2,T3 and T4 shoud not be Turned ON at the same instant of time. 13
  • 14. PWM SIGNAL GENERATION 14
  • 15. Single-phase induction motor• One stator winding• Squirrel cage rotor• 3 to 4 HP applications• Household appliances: fans, washing machines, dryers Electromagnetics Rotor Stator 15
  • 16. Induction motors working Electricity supplied to stator• Magnetic field generated that moves around rotor• Current induced in rotor• Rotor produces second magnetic field that opposes stator magnetic field• Rotor begins to rotate 16
  • 17. Speed torque curve SPIM
  • 18. AVR MicrocontrollerGroups: The AVR line is divided into to majorgroups; Tiny and Mega, with some additionalspecial function versions for specific applicationssuch as lighting, automotive, battery management,rf comms, and LCD drivers.Tiny: 1 to 8KB FLASH, 32 to 512 Byte RAM, 0 to512 Byte EEPROM, 6 yo 18 IO pins.Mega: 4 to 256KB FLASH, 0.5 to 8KB RAM, 1/4to 4KB EEPROM, 18 to 86 IO pins.
  • 19. AVR MEGA8535 MicroController RISC core running single cycle instructions. 32 general purpose registers. On chip hardware includes: Internal oscillators, timers, UART, SPI, USB, pull-up resistors, pulse width modulation, ADC, analog comparator, up to 4x40 LCD drivers and watch-dog timers. On chip in- system programmable Flash and EEPROM. 1.8- 5.5 Volt power options. Software controlled frequency and sleep modes with fast wakeup
  • 20. Advantages of Atmel AVR Cost. At the moment, the very lowest-price microcontroller available from any manufacturer is the RS 150. Speed: Not only are most AVRs capable of 20MHz (even really cheap ones like the ATtiny25/45/85 and ATmega48), but they actually run at near 20 MIPS; In addition, with the better addressing modes and registers of the AVRs, most operation can be done in only one instruction, where it often takes more than one instruction to do the same thing on a PIC Controller.
  • 21. Advantages of Atmel AVRPeripherals Many Atmel AVR µcontrollers, like many Microchip PIC µcontrollers, have a built-in 10 bit ADC. Some have LCD or USB drivers.Easy Programming All customizable code written in ANSI-C and thus easier to maintain. Modular concept: easier to integrate into existing designs. Slightly smaller code size in spite of high level language modules.
