A two transmission line model is built in the MATLAB Simulink software and the active power flow in one of the line is controlled by injection of voltage into the transmission line through an isolation transformer from the voltage source inverter. A unipolar pulse width modulation technique is used to generate the PWM pulses to the voltage source inverter. The phase angle of the reference sinusoidal signal is controlled to control the angle at which voltage is injected into the line so that desired active power flow is achieved.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129403450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a threat to power system too. After LOE, there is a reduction in internal voltage and rotor current of the generator. The absorption of reactive power from the system, leads the machine to act as an asynchronous generator when LOE occurs. In this context if the reactive power compensation is not done a major collapse can occur in the system. This paper depicts an algorithm for impedance based protection method with distance calculation for LOE condition. The algorithm for proposed protection method is developed, using Alternative Transients Program (ATP) Designer and PSCAD simulation software. The performance of the algorithms developed using both tools during LOE event on different operating conditions are studied and compared to find out the better performance of the algorithms. The results show that the ATP based algorithm is better for reliable protection against LOE conditions.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114463602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar cell leads the list of renewable energy sources attracting the scientist owing to its tremendous potential. Dye Sensitized Solar cells (DSSC) are considered to be eco friendly form of the solar cell. Natural dyes are environmentally and economically good choice to fabricate the (DSSCs) rather than the synthetic dyes. Several plants extracts are used as dyes to act as the sensitizer in DSSC. In this work we have prepared mesoporous TiO2 anode and the Al/C as counter electrode. The assembled DSSCs taking pomegranate extract as a natural dyes shows maximum of open circuit voltage (VOC) and short circuit current (ISC) comes out to be ~0.89 and ~5.46 µA respectively and the overall efficiency of the device is 0.89% among the other dyes.

On the other hand, these devices have some inherent drawbacks like increased number of switches, complicated control techniques and requirement of many voltage sources. A conventional topology uses 12 switches for a 7-level MLI design. In this paper, a modified reduced switch topology based 7-level inverter is proposed which require only 7 or 6 switches. Design, simulation and comparison of 7-level 7switch, and 7-level 6-switch inverters are carried out in MATLAB/SIMULINK environment.

To achieve full observability, PMUs should be placed optimally because the cost of PMU is very high. While placing PMU, importance may be given to weak buses, generator buses etc. Genetic Algorithm (GA) is used to solve optimal placement of PMU (OPP) with fully observability condition for base case and contingency case. SBX cross over and polynomial mutation is used in this algorithm in order to get best solution. IEEE 14 bus system, IEEE 30 bus system and IEEE 57 bus system have been taken to test this method. The results are shows the ability of GA to find the best solution for reducing the total number of PMUs with complete observability. To prove the ruggedness of this approach, the results are differentiated with other techniques.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121535065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
