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.

A Case Study for Optimum Sizing and Selection of Components in HRERs based Power Sysetm

The demand of electricity in rural India is increased two fold in the last decade and this demand has been met by the electricity grid extension so far. But the cost of extension of grid is very high and also depends upon land location, distance to be covered and more importantly size of the load. The recent researches show that adding the renewable energy resources to the system at the load centre makes the system less costly and environment friendly. 

The different configurations are compared and the selection of optimum configuration is based on the least value of cost of energy (COE) and net present cost (NPC) along with the highest value of renewable fraction (RF) and lowest harmful emissions (CO2) using HOMER (Hybrid Optimization Model for Electric Renewables) software is presented. A village location, Kotali Charkan (32-° 37' 0" North, 74-° 50' 0" East) in Jammu and Kashmir state of India is chosen for the system under the study, the hydro, solar and wind resources are available almost throughout the year on the selected village location.

Load Frequency Control in Three Area Power System using Fuzzy Logic Controller

In interconnected power system load frequency control has been used extensively. This study presents an application of a fuzzy gain scheduled proportional and integral (FGPI) controller for load-frequency control of a three-area electrical interconnected power system. The main aim is to design a FGPI controller that can ensure good performance. The paper present analysis on dynamic performance of Load Frequency Control (LFC) of three area interconnected thermal non-reheat power system by the use of Fuzzy Intelligence. 

The fuzzy rules are developed to ensure there is minimum frequency deviation occur when load is changed. The proposed controller limits the frequency deviations effectively as compared to conventional controller. The results has been verified by using MATLAB/Simulink software.
