Since correctness of any propagation model depends on topography clutter and other constraints. An understanding of the large scale transmission effects is very imperative for blueprint of appropriate communication system. In this, various propagation models are studied and compared against measured data available in [1] for the dense urban region of Delhi NCR, India at 1800 MHz. In the investigation part; path loss values are observed over a distance of 2 Km at every 100 meter for all the models used. Analytical result shows that free space model has the minimum path loss in case of values of frequency values, antenna heights that are specified. Ericsson, Cost-231 along with ECC models have shown preferable outcomes in comparison toh the experimental data attained in the vicinity of NCR, Delhi (INDIA). Amongst all the models under analysis, Ericsson has shown the best result. These results have been obtained both on Matlab and Simulink. Both are coming equivalent. The best model as per the result is optimized to make it closer to the measured data.","PeriodicalId":6761,"journal":{"name":"2019 International Conference on Power Electronics, Control and Automation (ICPECA)","volume":"11 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81460641","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}

This helps overcome the natural limitation of renewable energy deployments. More companies are looking at using SIs in their networks and closely study their impacts of these devices on the power system operation. Carefully controlled test environments show that necessary auxiliary support can be received from SIs. However, these modes actively inject power into the grid and may cause unknown problems. Especially if the SI control block is compromised by a hacker, these problems may have disastrous consequences. In order to fill this gap and investigate these points, a newly developed simulation platform called Sora-Grid is utilized to investigate impacts of cyberattacks on SI operation as well as power system operation at large. With the integration of Information Technologies (IT) and automation in power systems, cybersecurity has become a real threat and a concern. Most of the cybersecurity research focuses on large scale power plants that are connected at transmission level. This work analyzes the impact of such attacks on small-scale inverters that are connected to distribution networks. Based on these findings, cybersecurity measures can be developed to secure SI operation.","PeriodicalId":6761,"journal":{"name":"2019 International Conference on Power Electronics, Control and Automation (ICPECA)","volume":"21 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80909672","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}

First, the symmetrical optimum is a method to design a PI regulator gains, which is used in conventional SRF-PLL. This PLL is an extensively used synchronization method to connect a grid side power converter to the grid. Under ordinary grid circumstances, high-bandwidth of PI-regulator gains in SRF-PLL provide a quick and accurate detection of grid voltage amplitude and phase angle. However, under non-ideal conditions, the phase angle could be tracked but with less accuracy. How to further enhance their dynamic output during non-ideal grid situation is a significant challenge with the SRF-PLL. This paper discusses a second synchronization method based on a generalized integrator-frequency loop (SOGI-FLL) in second-order to solve this problem. A new SOGI-FDE-FLL consisting of SOGI-FDE and SOGI-FLL is used to quickly detect accurate monitoring of grid voltage, frequency and angle of phase. SOGI-FDE is used to identify a fundamental positive sequence voltage under unbalanced conditions. The effectiveness of the SOGI-FDE-FLL is confirmed through simulation and compared with Type-2 SRF-PLL.","PeriodicalId":6761,"journal":{"name":"2019 International Conference on Power Electronics, Control and Automation (ICPECA)","volume":"33 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89917471","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 proposed inverter scheme is realized with the help of 3 three-phase four-leg inverters. In 3-phase 12-pole mode (3PH-I2PO), the proposed MLI supplies a 3-level voltage for each phase winding of the PPMIM drive with an improved harmonic profile. This will minimize the amplitude of spatial harmonics in the airgap MMF, which results in better torque ripple in 3PH-I2PO operation. In this mode, for getting the same performance the PPMIM drive in w.r.t torque ripple the conventional 3-level 9-phase MLI’s requires 40 switches, while the proposed MLI requires only 24 switches, which means the switch count is reduced by 40%. On the other hand, the phase windings of the 9-phase PPMIM drive are rearranged into 3 sets of three phase winding groups, where each phase group has three balanced 1200 phase displaced windings. This phase grouping will give the flexibility to use the 3-phase space vector pulse width modulation (SVPWM) that enhances the linear modulation of the 9-phase PPMIM drives by 15.4% in 9-phase 4-pole mode (9PH-4PO). The 4th leg present in each three-phase four-leg inverter is used effectively for denying the circulating currents in phase windings in 9PH-4PO operation. The proposed MLI scheme is validated with the Ansys Maxwell FEM electromagnetic tool on a 5hp 9-phase PPMIM drive.","PeriodicalId":6761,"journal":{"name":"2019 International Conference on Power Electronics, Control and Automation (ICPECA)","volume":"16 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81985011","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}
