Unified Power Quality Conditioner (UPQC) Using Power Conditioner Apply to 3 Phase 3 Wire System by Using Hysterisis and PLL

The increasing demand of electric power is giving an emphasis on the need for the maximum utilization of renewable energy sources. On the other hand maintaining power quality to satisfaction of utility is an essential requirement. In this paper the design aspects of a Unified Power Quality Conditioner integrated with photovoltaic system in a distributed generation is presented. 

The proposed system consist of series inverter, shunt inverter are connected back to back on the dc side and share a common dc-link capacitor with Distributed Generation through a boost converter. The primary task of UPQC is to minimize grid voltage and load current disturbances along with reactive and harmonic power compensation. 

In addition to primary tasks of UPQC, other functionalities such as compensation of voltage interruption and active power transfer to the load and grid in both islanding and interconnected mode have been addressed. The simulation model is design in MATLAB Simulation environment and the results are in good agreement with the published work.

Control of Three-Phase Shunt Active Power Filter (SAPF) by Instantaneous Reactive Power Theory

Use of nonlinear loads has been increased in large extent in industries now-a-days which injects harmonic currents in supply system. These harmonics creates power quality issue. Shunt Active Power Filter (SAPF) is the popular and efficient solution to reduce these harmonics. SAPF can overcome voltage sag, eliminate harmonics and improves power factor. 

SAPF reduces total harmonic distortion (THD) to acceptable level. Reference current generation is the heart of APF. Reference current generation using instantaneous reactive power (IRP) theory is presented in this paper. IRP theory is widely used to control active power filters (APFs). Modeling of this technique is implemented in MATLAB simulink.

Comparative Study of DGA Methods for the Incipient Fault Diagnosis in Power Transformer Using ANN Approach

Power transformer being a major apparatus in a power system, monitoring of its in-service behavior is necessary to avoid catastrophic failures, costly outages. Power transformers are considered capital investments in the infrastructure of every power system in the world. Dissolved Gas Analysis (DGA) is an effective method for the early detection of incipient fault in power transformers. But the main drawback of the DGA ratio methods is that they fail to cover all ranges of data. 

The interesting results revealed by this study are serving as the underlying principle to carry out an ANN based insulation condition monitoring system. ANN approach is automatically capable of handling highly nonlinear input output relationships, acquiring experiences which are unknown to human experts from training data and also to generalize solutions for a new set of data.

Experimental Study on High Performance Concrete with Glass Fibre

In reviewing technology advances through the centuries, it is evident that material development plays a key role. Considerable efforts are still being made in every part of the world to develop new construction materials. In the construction industries, concrete technology is heading towards entirely new era by way of using glass fibre with high performance concrete. Strength and durability are the two major factors to be considered in the design of structure subjected to static and dynamic loads. 

Characteristics of conventional concrete might not be entirely applicable to high strength concrete because of their difference in failure characteristics and engineering properties. HPC is multi-componential interactive construction material. High strength is not only the parameter that has to be looked in the design of structural element. There are various other parameter such as modulus of elasticity, bond strength, flexural strength, and splitting strength etc. 

that tend to change the mechanical properties and failure characteristics of hardened concrete, expressive in the form of deflections, ultimate load, formation of cracks and crack pattern etc. High performance concrete (HPC) is a specialized concrete designed to provide several benefits in the construction of concrete structures. The use of fibres in concrete has gained enormous popularity in the last decade. Studies have shown increasing evidence that the brittle behavior of HPC can be overcome by the addition of short Glass fibres of small diameter in the concrete mix. 

The present study aims to investigate the integration of Glass fibers with HPC of a designed mix of M60 grade of concrete. The influence of the cementations material dosage, cementultra-fine ratio, percentage of fibers, and the mixing procedures on the mechanical properties of concrete was studied by preparing several concrete mixes. Glass fibre specifically designed for use with concrete composites as admixture. Three different concentrations such as 0.75%, 1% and 1.25% of Glass Fibre by weight of cement were used. 

Glass fibre first dispersed in dry mix and surfactant using an ultrasonic mixer as per state-of-the-art techniques and then combined with water and high performance concrete. The various mechanical properties like Compressive, Flexural and Split tensile strength can be improved with the addition of low concentrations of Glenium ACE 30 in high performance fiber reinforced concrete.

Experimental Study on Physical Properties of High Strength Concrete With and Without Horse Dung

Use of fibres is not new to the construction industry. But the way they are being used and its ever-growing varieties have always made it a burning topic for the researchers. The principal reason to incorporate fibres into a cement matrix is to increase the compressive strength and to improve the soundness characteristics of the resultant composite. 

Previous studies related to the use of natural organic fibres in concrete have shown strength variation with respect to the various types of fibres and fibres content. In the present investigation, an attempt has been made to design a high strength Fibre Reinforced Concrete by proportioning the mix with moisture free pulverized natural organic fibres obtained from horse manuredung. 11 mixes were prepared separately to determine the characteristics and properties of freshly laid concrete. 

33 cubes were casted for the determination of compressive strength and 12 beams were casted for the determination of flexural strength of concrete. Later study was carried out on this designed concrete mix by considering different parameters such as fibre content, proportioning of fine aggregates, time (days) and types of tests (Destructive and Non Destructive test). Results of the study have shown that the performance of designed concrete mix with different mix proportions and different percentage of fibres as additive and replacement of fine aggregates are far more efficient and superior to the conventional mix. 

As the proportion of percentage of fibers is increased, the performance and strength of freshly mixed as well as of hardened concrete cubes gets improved. After increment in percentage of fibers in mixes, a stage comes where the quantity of fibers is well enough to affect the performance as well as strength of concrete cube. This research summarized the use of horse manuredung, a natural organic fibre by some percentage in the concrete mix to get favourable workability, compressive and flexural strength.

An Analysis on Increasing the Loom Speed

In this project, an analysis has been carried out on the speed increasing process of Cone over pick loom of 36" reed space, The parts like picking system, Shedding mechanisms, Brake, beat-up system etc are given importance in terms of design changes to give a smooth picking, checking and effective braking and also smooth running of crank at higher speeds. 

The loom characteristics with respect to the above mentioned parts are analyzed and to suit the existing loom parts, new designs have been evolved with the help of PV ATIRA loom part manufactures. The parts received from them are analyzed for their effectiveness, in comparison with the existing parts. The picking mechanism, shedding systems and the brake are mounted on the loom after taking out the respective existing parts. 

The loom is run without any difficulty at the existing speed. The higher speed has not been tried due to non-fixation of the new checking device, central supporting bracket and the bearing for the crank, because of shortage of time. The analyzed facts reveal the advantages indication in the picking force, braking force etc. The picking force is expected to reduce by 14%.Since spring swell is provided in modified loom, the peak retardation value is reduced by 24.3%.

sley eccentricity ratio is increased by 7.1% as the connecting arm length is reduced. A sound level is another important factor. With existing parts the sound level measured at picking bowl and shuttle box are 102dB and 109dB, respectively. But in modified loom they are 97dB and 105dB. So, a reduction of noise level by 9dB is achieved by the modification which is an encouraging factor to go in for higher rate of pick insertion. At picking bowl noise level is reduced by 5% and at shuttle box, it is reduced by 3.9%.
