A New Weir Cum Causeway Design of Varachha Site under Surat Smart City Project

Weir is a solid structure constructed across the river to raise the water level in the river flow. We proposed two sites: Amroli(FRL=4.0m) and Varachha (FRL=4.0m &5.0m). The maximum FRL of Varachha site has to be about 5.0m used in design. We desired that the feasibility of keeping FRL 5.0 to get a water storage as well as wider and longer pond so, we selected Varachha site. We have selected L33-R33 section on river Tapi is safe for our design and no large afflux create on it. 

To calculated a design discharge and return period factor for 50 years for Varachha site. According to the model studies, the discharge 12,00,000 cusecs, 34000 TCM design given and calculate silt factor is 1.2 and the design discharge is 24,000 cumec.We given hydraulic design based on IS code 6966 (Part-1):1989 Hydraulic Design Of Barrages And Weirs-Guidelines. Weir length was 450m, crest level 8m, crest width 10m. We providing 16 nos. Of Automatic gates (5 x3.5m). 

Hydraulic design given in two parts: (1)Floor Length Weir bays calculation and (2) Under sluice calculation 100% discharge calculation considered as per IS code 6966 (Part-1):1989 calculated H.F.L 14.10m. The weir may be combined with a submersible bridge, it's solve a traffic of this Varachha site and to make ease of 24x7 potable drinking water for varachha region people. The water also available for industry uses and other activities.

Productivity Improvement using Lean Manufacturing '“ A Case Study at Muththamizh Industries

At the present scenario, the Lean Manufacturing has become a worldwide phenomenon. A large number of organizations are following Lean technologies and experiencing vast improvement in quality, production, customer service and profitability. Muththamizh industries in Palani is a manufacturing company that manufactures variety of agricultural oriented machines. In this work to adopt the Lean manufacturing concept in this industry by using Value Stream Mapping (VSM) technique and to reduce the wastes such as long lead time, defects, material waste etc. 

Our project focuses on creating current and future state value stream maps which, when implemented will decrease the current lead time of manufacturing thereby improving the productivity of industrial shop floor. From their products, the team chose Chaff cutter machine as a product family and worked on them. From the Current Value Stream Map created the lead time for the product is found to be 3 to 3.34 days right from the processing of raw materials till the product is ready to be shipped. From the map created, various stages that contains bottlenecks in production were clearly identified and remedial measures were taken to eliminate those bottlenecks. 

Various lean tools such as Kaizen Bursts, 5S and other methods to eliminate the wastes were identified and implemented effectively. After remedial measures were adopted the data is tracked again and Future Value Stream Map is drawn. From the map it was clear that the lead time for the product was reduced to a certain extent of up to 4 hours. Therefore our primary goal of the object was achieved by adopting lean techniques and the productivity and efficiency of the organization was increased.

Effect of carbon dioxide on the performance of Spark Ignition Engine by Hydrogen Inject with Biogas Fuel

Methane and carbon dioxide are the two main constituents of biogas. One of the reasons of poor combustion is the presence of carbon dioxide in the biogas. Biogas also has traces of nitrogen, hydrogen, oxygen and hydrogen sulphide. Because of a high investment cost and a heavy infrastructure, only fifty percent of the biogas production upgrades (decrease CO2%) by use of water scrubber. so the natural gas replacement is very low. This experiment is conducted on modified single cylinder 97.5cc petrol engine, to work it as a biogas-hydrogen fuel spark ignition engine.

Hydrogen added in small amounts by HHO generator (hydroxy) kit to decrease concentration of CO2 in biogas power and find out the effect of CO2 on the performance. The experimental results show that the large quantity of CO2 present in biogas lowers its calorific value, flame velocity and flammability range compared with natural gas. So it can be utilized in an IC engine with the hydrogen.

Prediction of safe working frequencies of screening machine by Harmonic Analysis

The vibratory screening machine is used in different industries like mining, pharmaceutical, food etc. In the past, the study of screening machine has been done on the basis of its design parameters like diameter of wire, length, mesh size, throwing index etc. The work regarding vibration parameters is not widely done in the past. A little work on mathematical modeling has been done on the rectangular type vibratory screening machine. In this paper modal and harmonic analysis has been done to predict the natural frequencies of different mode shapes of the circular vibratory screening machine. This analysis can be used as the methodology for the further study of the VSM. In this dissertation work it the design and working frequencies of the screening machine are of safe region.

Improvement in Power Quality in Power system Through of DPFC

In this paper a new member of FACTS family Distributed Power Flow Controller has been discussed. DPFC originates from unified power flow controller (UPFC). DPFC can be treated as UPFC as both have shunt and series controller beside the main difference in size and number of converter. DPFC maintains the terminal voltage constant by regulating the DC link voltage. As the D-FACTS converters are single-phase and floating with respect to the ground and no need for isolating the high voltage as in case of UPFC. 

DPFC has two control circuits for both series and shunt controller. Shunt controller uses classical PI controller and in shunt controller synchronous d-q-0 based controller is used. The effectiveness of DPFC is proved by MATLAB/Simulink model. The results shows that the DPFC can effectively compensate the harmonics and maintain the voltage level at the load terminals.

Reactive Power Compensation and Limiting Harmonic Current using Shunt Active Power Filter

In this paper, a shunt active power filter (SAPF) based on adaptive hysteresis band current controller (HBCC) is proposed for limiting the harmonics in load current and also compensate the reactive power for 3 phase non-linear load. The HBCC calculate the active power and reactive power, transforms them in d, q and 0 components using Clarke's transformation then calculates the compensating values of active and reactive power to inject them further in system. 

The HBCC determines the switching signals of the SAPF, and the algorithm based on an extension of synchronous reference frame theory (d-q-0) is used to determine the suitable current reference signals. The results of simulation study of SAPF control technique presented in this paper is found quite satisfactory to eliminate harmonics and reactive power components from utility current.

Mitigation of Voltage dip in WECS using UPQC

Currently, the quality of supplied power is important to several customers. Power quality is a service and many customers are ready to pay for it. In the future, distribution system operators could decide, or could be obliged by authorities, to supply their customers with different PQ levels and at different prices. A new device that can fulfill this role is the unified power quality conditioner (UPQC), composed of a power-electronic series main unit installed in the medium-voltage/low-voltage (LV) substation, along with several power-electronic shunt units connected close to the end users. 

The series and parallel units do not have a common dc link, so their control strategies are different than traditional UPQC control techniques. This device can achieve general improvement in power quality, reducing the most common disturbances for all customers that are supplied by the mains by using only the series unit. Additional increments in power quality (i.e., mains power interruptions, faults), can be provided to the customers who need it (custom power) by the shunt units. 

The UPQC is controlled to mitigate voltage fluctuations and to regulate the WF terminal voltage at PCC caused by pulsating WF generated power and system load changes respectively. Simulation results show that there is reduction in power fluctuations at grid and voltage fluctuations at PCC. The UPQC scheme is validated to mitigate the power quality problems like Voltage Sag, Swell and Harmonics and WF stability.
