In the proposed scheme the solar PV and grid are integrated using a three leg voltage source converter consists of six IGBTs, three interfacing inductors and a DC bus capacitor. The neural network based scheme is used for estimating fundamental real and reactive power components of the load current in all three phases independently therefore the three phase grid current remains balanced and sinusoidal under all type of loading conditions including unbalancing in load currents of three phases. The proposed controller mitigates the harmonic current, compensates reactive power need of the system, improves system power factor and regulates the system voltage at the point of common coupling (PCC).","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125585304","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}

Mechanical faults such as Broken Rotor bar fault of IM along with supply PQ disturbances create a high degree of non-linearity in the supply. This non-linearity is examined by stator current signature analysis which involves the computation of the Negative Sequence Components (NSC) and Total Harmonic Distortions (THD) of the stator current. These values are given as inputs to the Artificial Neural Network (ANN), Support Vector Machine (SVM) and k-Nearest Neighbor (kNN) classifiers. The results of the classifiers are obtained and compared. It is seen that the classification accuracy for ANN is found to be 90.63%, while for SVM is found to be 92.71% and that of kNN is found to be 85.41%.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132637199","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}

Development of DC power system is chosen as a solution to overcome many of those impacts. Photovoltaic arrays used here will generate an output at a low voltage level, to integrate this to high voltage DC grid a high voltage gain multi level boost converter (MLBC) is chosen, which includes conventional boost converter circuit in addition to switched capacitor circuit. MLBC offers high gain factors without attaining extreme duty ratios, continuous input current, low stress voltage across the switch and reduced component ratings. Adaptive perturb and observe (P&O) fuzzy MPPT controller is chosen here to track the maximum power point (MPP) for fluctuating input irradiation. MLBC topology along with chosen MPPT controller will achieve dual functionality of high voltage gain and maximum power point tracking. The performance of chosen MPPT on MLBC is compared with other MPPT techniques. The results of Matlab simulation were illustrated for corroborating its performance.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131218116","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}

The main driver towards this initiative is to achieve energy security by exploiting ways and means which are sustainable in nature and produce clean energy. This paper presents the philosophy towards commissioning of the country's first MW level grid-connected wind-solar hybrid project by M/s ReGen Powertech Pvt. Ltd. Under this project, Solar Photo-Voltaic (SPV) system has been additionally commissioned in a wind-farm premises, where a Wind Energy Convertor (WEC) is already operational. The combination facilitates substantial saving on number of counts, which include sharing of common land as well as some of the equipment, like inverter, transmission network for the evacuation of power, and common auxiliaries. Furthermore, by combining wind and solar, which are largely complimentary in nature, the overall variability of the output produced has also been moderated and the combined output is certainly more conducive towards integration with the grid. This paper presents the overall philosophy behind the subject topic and the way forward towards enhancing the capacities of such installations in the country.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130933127","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}

Results have been organized for different case considerations. It is obtained that losses can be significantly reduced with optimum application and utilization of available loss reduction methods. The effect on network voltage profile, line loadings and bus angles has been compared with the base case.

The paper presents detailed analysis of power transfer efficiency between two independent coils separated by distance of 15 cm. The analysis involves an effect of coil geometrical dimensions on power transfer efficiency and mutual inductance between transmitter (TX) and receiver coils (RX).
