HARMONIC MITIGATION USING D STATCOM THROUGH A CURRENT CONTROL TECHNIQUE | J4R Journal Vol. 2 Issue. 1

HARMONIC MITIGATION USING D STATCOM THROUGH A CURRENT CONTROL TECHNIQUE

The harmonic mitigation using shunt active filters are most widely used in industrial and commercial applications. In this paper a Multi-Level Inverter is considered as DSTATCOM to compensate harmonics. The mathematical modeling of the system and design of the controller using synchronous reference frame theory is also presented. The nonlinear load generally known as diode rectifier load and an unbalanced load is simulated with the system using MATLAB/SIMULINK. 

         D-STATCOM also contributes in an unbalanced voltage sag mitigation, drives the source current to be fundamental frequency sinusoidal and balanced, also capable in achieving reactive power compensation. In addition to this, several topologies like series shunt and hybrid power filters [3] are designed and implemented to meet IEEE 519-1992 guidelines of harmonic standards. The multilevel inverter topologies are provided highest importance in reducing the harmonic components. These multilevel structures are best suited in obtaining high powers and with a simple conversion process using semiconductor switches. This multilevel approach synthesizes the voltage levels of the bridge circuit and attains the waveforms to be sinusoidal and balanced with reduced harmonic content

             The mathematical modelling of the control structure to the D-STATCOM, Nonlinear load and the modelling of 5 level Cascaded H Bridge Inverter with Phase shifted PWM technique is presented. It is proved that the CHB based multilevel inverter mitigates the harmonics in the source current at distribution system. The results from the simulation demonstrates the effectiveness of the D-STATCOM in providing balanced sinusoidal source currents, though the load currents are distorted. It is noted that the THD is 2.15% which is well within IEEE 519-1992 standards.

IMPLEMENTATION OF EFFICIENT ADDER USING MULTI VALUE LOGIC TECHNIQUE J4R Journal Vol. 2 Issue. 1

IMPLEMENTATION OF EFFICIENT ADDER USING MULTI VALUE LOGIC TECHNIQUE

The digital logic circuits are restricted for the requirement of interconnections. This difficulty overcomes by using a big set of signals over the same chip area. Multiple-valued logic (MVL) designs contain more importance from that perspective. This paper gives the fabrication of a multiple-valued half adder and full adder circuits. This technique advantageous for large scale circuits due to which large power dissipation with increased speed can lead to the development of extremely low energy circuit’s use for the high performance required for number of applications. Multiple-valued logic (MVL) designs are gaining more advantageous from the design of a multiple-valued half adder and full adder circuits. The presented adders are design in Multiple-Valued voltage-Mode Logic (MV-VML). In quaternary half adder, quaternary logic levels are exploited for the intention of addition. Addition operation is executed with minimum number of gates and less depth of net. The design is targeted for the 0.18 μm CMOS technology. Circuit is design by using Advanced Design System software {ADS software}. In this paper we try to find area, power and speed of the design HAq / FAq without any need of conversion, and compare to existing binary circuits [HAb / FAb].

             In this paper we review the historical developments in this field, both in circuit realizations and in methods of handling multiplevalued design circuit. In the recent years MVL gaining the importance due to its inherent benefits like high speed , low area , and low power(Vm),we found during analysis of MVL, it has great high message communication ability .in earlier work quaternary [mvl0-3] arithmetic operations like addition, subtraction and multiplications presented which use q-b conversion, b-q conversion for implement the arithmetic operation. We proposed half adder and full adder in quaternary to quaternary without any conversion which then lead more optimization at farther level. 

I am very much thankfull to Mr. Vasundara Patel K.S., K.S. Gurumurthy, for giving there valuable guidance towards therwonderful paper , i am also thankful to B. Radanovic, M. Syrzycki, Ricardo Cunha for giving the impotance of MVL techniques This Article is Researched By Prof Abhijit kalbande From PRMCEAM , Badnera and Published by J4R Journal

Abstract:

Life Insurance Corporation of India (LIC) is the India’s largest Life Insurance Company. LIC has acquired monopoly power in the solicitation and sale of Life Insurance Policies in India. LIC has registered a six per cent increase in market share to 78 percent during the current financial year. LIC's market share at the end of March 31, 2014, had stood at 72 per cent of all new policies sold during the last financial year (2013-14). The combined market share of 23 Private Life Insurance Companies has 22 per cent during the current fiscal, according to the latest figures. LIC has 53 products in his portfolio and sold around 80 lakh policies till the end of July 2014. LIC has set the new target of Rs. 54000 crores as a first premium income for 2015-16. LIC has a 78 per cent share because the private sector companies focus more on big ticket premiums, while LIC offers at a minimum premium of Rs 250 with life insurance value of Rs 30,000. This enables the public sector company to achieve the social objective of taking its insurance cover to a wider range of the country's population. LIC also has the lowest outstanding claims ratio. LIC had settled 99.8 per cent of death claims while the Private Sector Companies had settled 96.8 per cent of such claims. In this research paper we studied Customer Satisfaction towards Life Insurance Corporation of India (LIC), because Consumer Satisfaction is the first step to Achieve Consumer Loyalty. If the customers of Life Insurance Corporation are Satisfied and Happy then and then only they may be Loyal to the LIC. For this research Primary Data was collected from the various customers of Life Insurance Corporation of India. For data collection designed Questionnaire was distributed and collected from the respondents.
