SPEED CONTROL OF A THREE PHASE INDUCTION MOTOR USING PWM INVERTER

Be present it household application or engineering, motion control is required all over the place. The systems that are working for this idea are called drives. Such a system, if makes utilize of electric motors is known as an electrical drive. In electrical drives, use of different sensors and control algorithms is done to control the speed of the motor use suitably speed control method. Past only dc motors were effective for drives requiring variable speeds due to ease of their speed control methods. The conventional methods of speed control of an induction motor were either too expensive or too inefficient thus restricting their application to only constant speed drives.

Speed control of Induction Motor Using Push-Pull Converter and Three Phase SVPWM Inverter

Speed control of Induction Motor Using Push-Pull Converter and Three Phase SVPWM Inverter

Fig 5: Structure of fuzzy logic controller The design of a Fuzzy Logic Controller requires the choice of Membership Functions. The membership functions should be chosen such that they cover the whole universe of discourse. It should be taken care that the membership functions overlap each other. This is done in order to avoid any kind of discontinuity with respect to the minor changes in the inputs. To achieve finer control, the membership functions near the zero regions should be made narrow. Wider membership functions away from the zero region provides faster response to the system. After the appropriate membership functions are chosen, a rule base should be created. It consists of a number of Fuzzy If-Then rules that completely define the behaviour of the system. Fig.6 represents membership function plots. The range for these functions is from -1 to +1. The number of membership functions selected for error and change error are seven and for the output we select eleven.

For speed control of 3-phase induction motor Low-Noise Inverter M1S Series Operating Instructions

Precautions Note the following precautions in order to use the inverter properly. 1. Arrange for the power source capacity to be between 1.5 to 500kVA the inverter's capacity. An excessively high peak current may flow to the power input circuit, and damage the converter section if the wiring length between the power source and the inverter is shorter than 100 m with a power source exceeding 500kVA, or the phase- advancing capacitor is switched on the power source side. In this case, provide individual power factor-enhancing AC reactors that match the inverter's capacity on the inverter input side.

Control and Monitoring of 3 – Phase Induction Motor Using PLC

Technology, Bahal, Dist. – Bhiwani, Haryana, India 2 Associate Professor & Head Department of Electrical & Electronics Engineering, BRCM College of Engineering & Technology, Bahal, Dist. – Bhiwani, Haryana, India 3 ABSTRACT: Induction motors are widely used in various industrial fields due to their simple, robust and reliable operation. Hence, to get the proper output and efficiency continuous monitoring and controlling is necessary [1]. In this paper, various aspects of three phase induction motor such as speed; temperature, voltage and current are monitored and controlled using the PLC. As sometimes the condition like over voltage, under voltage, overloading, overheating, over speed etc. may give rises to unwanted conditions for the motors [4][5]. Therefore as soon as such condition arises the motor should be turned off automatically. There are various methods for controlling the induction motor such as online fault detection, stator monitoring techniques, systems based upon microcontrollers or PICs. In this paper the method adopted is with the help of PLC (Programmable Logic Controllers). Here the various factors are monitored using sensors and PLC [3]. And if any harmful condition arises motor is turned off automatically.

V/F Speed Control of Induction Motor by using L Z Source Inverter

V/F Speed Control of Induction Motor by using L Z Source Inverter

The Z source inverter system reduces line harmonics, improves power factor and reliability, also extends output voltage range. Trans Z source inverter also has buck and boost function that cannot be achieved by traditional VSI and CSI. It reduces voltage stress and increases voltage gain. In this paper, L-Z source inverter is used because same drawbacks are present in Z source inverter topology mentioned as follows: l) Capacitors are used in the ZSI network, thus high voltage and large capacity capacitors should be used, which results in large volume, expensive cost and reduced life span of system. 2) It cannot suppress the inrush current and the resonance introduced by Z source capacitors and inductors at start up, thus causing voltage and current surge which may destroy the devices. Thus, to overcome these drawbacks, a new topology of L-Z Source Inverter (L-ZSI) is proposed. L-ZSI does not use capacitor and thus it enables to limit high inrush current at start up, suppresses the resonance and improves the efficiency of power supply. So, L-Z source inverter is employed to run an induction motor and control its operating speed by V/f method.

Figure 12: Output line voltage between U and V phase at channel-A Figure 13: Output line voltage between U and V phase at channel-A VI. CONCLUSION As per simulation results, we find out the Space Vector Pulse Width Modulation of a two level inverter provides the additional advantage method, more DC bus voltage utilization and to generate less output current and voltage THD compare to sinusoidal PWM. The main advantage of using SVPWM in VFD is to get 15% more output voltage than SPWM. In V/f induction motor control techniques, get constant motor torque upto rated speed. AC drive with V/f techniques solve many application likes fan, pumps, compressor, conveyor and etc, save energy to reduce the cost. V/f drive with close loop techniques is used, where the load (torque) changing require with constant speed. Current limit function with VFD is protects the motor. Proper components selection (Hardware design) of VFD can give better VFD life and ultimate reduce the cost.

Speed Control of Three Phase Induction Motor by using V/f Method

Speed Control of Three Phase Induction Motor by using V/f Method

Pulse width modulation is the commonly used for controlling speed and frequency of motor. This can be done by using micro- controller. In this research we selected a range of 5Hz to 50Hz frequency using PWM. The basic principle of PWM is that a sine wave is generated in the microcontroller which is super imposed on a triangular wave. This results in a square wave which is then fed to inverter section. with the changing duty cycles of the pulse, width of square wave is controlled . Basically duty cycles describes the time for which pulse waveform turned on and off. Thus by switching the waveform between two discrete levels the square wave is approximated with a sine wave of desired duty cycles. These pulses are fed to the switches for turning ON and OFF as desired. By turning on switches in any order, the phase and the rotation of electric motor can be changed. So making of phase voltage positive, negative or zero, variable frequency get at output. As a frequency directly proportional to speed of motor and motor speed varied according to requirement or application. So inverter is a unit where filtered DC supply is being converted to AC supply which is fed to electric motor.
