 Abstract

In this paper, a power quality controller suitable for microgrid is proposed, which can cater for the peculiar requirements of microgrid power quality, such as the harmonic high penetration and frequent voltage fluctuations. A dynamic voltage restorer (DVR) is proposed to improve voltage quality in a micro-grid. A DVR is a DC to-AC switching converter that injects three single phase AC output voltages in series with the distribution feeder and in synchronism with distribution system voltage. It is an interface equipment between utility and customer, connected in series between the supply and load to mitigate the three major power quality problems namely, the voltage sags, swells and interruptions. One of the major problems dealt here is the voltage sag and swell. DVR is the most efficient and effective modern custom power device having fast dynamic response to the disturbances. Simulation result showed that proposed topology is able to minimize power quality issues like voltage sag and swell.

 Abstract

Flexible Alternating Current Transmission Systems (FACTS) devices have been proposed as an effective solution for controlling power flow and regulating bus voltages in electrical power systems, resulting low system losses, and improved stability. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level. The FACTS devices placement problem is commonly solved using heuristic optimization techniques which are diverse and have been the subject of ongoing enhancements. This paper presents a survey of the literature from the last decade that has focused on the various techniques applied to determine optimal location of FACTS devices. Several models and methods have been suggested for the optimal location and parameter setting of FACTS devices. This paper presents an overview of the state of the art models and methods applied to the power system problems, analyzing and classifying current trends in this field.

 Abstract

A novel fault diagnosis method for open-circuit faults on a traction rectifier is proposed in this paper. When an open-circuit fault occurs in any leg of the rectifier, indication will be generated accurately to identify the faulty leg without utilization of any extra sensors. Furthermore, the faulty rectifier can be reconfigured to maintain its full output rate to prevent traction rectifier breakdown. The fault diagnosis process is neither related to control trigger signal nor the load fluctuation. The involved parameters are the input and output voltage of the rectifier, which are the most common parameters in rectifier control. Here five additional switch sets are adopted for the fault diagnosis process to reconfigure the topological structure between traction rectifier and traction transformer. In this system two set of traction rectifier is used if any rectifier set one set is affected from the open circuit fault it would be switch over to the next set then fault is diagnosed meanwhile the original structure of the rectifier is retained. Analysis, design, and implementing consideration for both normal and abnormal operating situations of the traction rectifier are present in this paper. In this method no additional sensor, many hardware requirement The experiment is processed to verify the effectiveness of the theoretical analysis.

 Abstract

In this paper, a new type of motor drive operating mechanism of High Voltage Circuit Breakers (HVCB) based on techniques of power electronics and motor digital control has been studied. In this paper, the structure and the moving principle of operating mechanism for HVCB is analyzed and the control strategy for PMSM drive operating mechanism is described. The simulations, calculations and actual tests all indicate that parameters of the drive-motor such as the rotational inertia, the output torque and the output power will have impact on the performance of the operating mechanism. The research work of this paper has shown that it is advisable to adopt motor for driving operating mechanism of HVCB and such mechanism can meet the requirements for opening and closing operation of HVCBs.

 Abstract

The operating performance of wind electric generators has considerable stress on the quality of electric power and reliability in the performance power systems [1]. Power quality issues such as voltage dip, harmonic distortion and reliability problems are main considerations in this work. The voltage distortion & reactive power issues are also considered. The powerful MAT LAB tool is used to analyse the power quality issues and other reliability problems in this paper and also the performance of induction generator connected with grid is also analyzed for power quality problems. The compensator is designed to inject reactive power to overcome power quality problems and also for better grid operation. There is a continuous variation in terminal voltage because of the varying wind speed. The addition of STATCOM into the system supports to maintain the active power, reactive power and terminal voltage as constant and STATCOM for steady state and dynamic impact study is presented, and the model is validated by comparing with the actual field data.The wind turbine generators have power electronic based converters can be effectively utilized for efficient control of power, but they generate harmonics. The modified STATCOM as shunt active filter which is used for reducing system harmonics and to improve the system performance. The STATCOM model is implemented using PIC controller

 Abstract

This project investigates the design of a cost-effective and efficient solar powered irrigation pump utilizing a switched reluctance motor (SRM). It utilizes a simple DC-DC boost converter as a power conditioning stage between SPV array and the motor drive. The control of solar photovoltaic (SPV) array output power at maximum power point (MPP) and facilitating the soft-starting to the SRM drive, are two prime functions of the boost converter. The use of a 4-phase SRM drive minimizes the torque ripple and increases the number of strokes without incrementing the number of rotor poles. The low number of switches in a mid-point converter used to energize SRM phases further enhances the performance of the system. The speed control of the motor using the pulse width modulation (PWM) switching of split capacitor converter eliminates the requirement of additional sensors on the motor to control its speed. The proposed water pumping system is designed, modeled and its performance is simulated on MATLAB/Simulink platform and its responses are analyzed, under the varying environmental conditions, which authenticate its appropriateness as an irrigation pump.

 Abstract

The wind turbine acts as a prime-mover for doubly fed BLDC generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The simulation results show a significant enhancement in shortening development time and improving dynamic performance of the BLDC motor compared to the conventional speed control of BLDC motor drive. The wind turbine acts as a prime-mover for doubly fed BLDC generator. The three phase BLDC motor has wide applications in industries due to its rugged construction, efficiency and low cost. Neutral point clamped is used for estimation of feedback controller parameters for three phase BLDC motor fed from wind turbine .Neutral point clamped offers certain advantages such as simple steps. The PFC BL-Luo converter has been designed to operate in DICM and to act as an inherent power factor pre-regulator. An electronic commutation of the BLDC motor has been used which utilizes a low-frequency operation of VSI for reduced switching losses. The simulation results show a significant enhancement in variable industrial applications and improving dynamic performance of the BLDC motor compared to the conventional speed control of BLDC motor drive. The proposed concept can be implemented to adaptive variable speed control scheme for wind energy based BLDC motor using Matlab/Simulink software

 Abstract

A zeta converter is utilized in order to extract the maximum available power from the SPV array. The proposed control algorithm eliminates phase current sensors and adapts a fundamental frequency switching of the voltage source inverter (VSI), thus avoiding the power losses due to high frequency switching. No additional control or circuitry is used for speed control of the BLDC motor. The speed is controlled through a variable DC link voltage of VSI. An appropriate control of zeta converter through the incremental conductance maximum power point tracking (INC-MPPT) algorithm offers soft starting of the BLDC motor.
