For the field trails, we started with the set of parameters which is recommended by the ITU advisor. After monitoring for some period of time, some parameters were adjusted. To evaluate the practical performance of each parameter set, system parameters and received field strength are evaluated in various test sites. In this field trial, signal quality is evaluated by test staffs, and compared among parameter sets. After the optimal parameters were set, the areas of weak received signal were considered. Then some additional transmitted sites are added in some particular locations. Since the trials consider various practical reception environments, the test results can be used as a guideline for implement DVB-T2 networks in Thailand Digital Switchover (DSO).","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132048063","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}

In Thailand, the government has approved energy department plan to increase its renewable energy target, which will include three and single phase PV installations. This paper presents a study on voltage unbalance due to the increased rooftop PV installations on low-voltage residential distribution system. The single-phase rooftop PV model is developed by Matlab/Simulink and is used in the study for analyzing the voltage unbalance under different installation ratings and locations. The obtaining results can be used as guidelines for electric distribution utilities to determine the maximum PVs installations in low-voltage residential distribution systems without affecting the power quality issues.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132299191","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 conventional synchronously rotating reference frame (CSRRF)-based voltage sag detection is the most famous voltage sag detection method in the past. However it has a huge disadvantage as a long delay of detection time. The detection time is moderately improved by the improved modified synchronously rotating reference frame (IMSRRF)-based voltage sag detection. This paper presents DLPF-based voltage sag detection which is providing the shortest detection time when comparing to other methods. The performance of proposed voltage sag detection is verified via computer simulations in various conditions.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117112531","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 key operation waveforms of the full-bridge converter from absolutely no-load to full-load conditions are described. In order to confirm wide load variations, the converter should not only operate with soft-switching from full load to no-load condition with satisfactory efficiency for the full range of operation, but the voltage across the output diode bridge also needs to be clamped to keep away from any reverse voltage overshoots arising during turn-off of the output rectifying diodes. In order to achieve zero-voltage switching (ZVS) at turn-on for all load conditions, the converter employs auxiliary coupled inductors near lossless auxiliary circuit. Moreover, the proposed topology is based on a current driven rectifier in order to clamp the voltage of the output rectifying diodes and also obtain ZVZCS of the converter operation, resulting in superior efficiency for all load conditions. In this paper, the converter operation is described. Experimental results provided from a 1 kW prototype validate the feasibility.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125043280","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 trajectory learning technique utilizes vehicle odometry and sensor scanning data. The aim of this technique is to find the obstacle free path for mobile robots. Consequently, a free configuration space from the higher dimension sensor data is extracted by employing highest eigen-vectors technique [2] in discrete time scans during robotic manipulation. Integration of these eigenvectors in discrete time results in a new trajectory. This new trajectory is free from dynamic and static obstacles. The trajectory generation algorithm was tested on a nonholonomic LEGO NXT differential drive robot equipped with sonar and position sensors. The trajectory learning proposed method has been tested in different scenarios which resulted into promising preliminary results and are shown in this paper.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129964681","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}
