Therefore it is the responsibility of the power utility to provide the reliable service and also in case of power curtailment, utility should promise as maximum as possible amount of power supply to all the connected loads of high priority customers and partial loads of low priority ones. The demand side management system used so far could take care of the consumer convenience to very less extent. There is some contribution towards demand response at the distribution feeder level and at the building area network level, but very less work has been done so far, about the substation level demand response. Therefore this paper proposes a substation management system, in which the demand limit can be allocated by Hierarchical Cumulative Voting (HCV) method based on the assigned weight to the respective consumers. The results show that, the demand limit can be assigned efficiently, which in turn can be used for Demand Response (DR) strategy, when the load exceeds the available power from the utility.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"1 1","pages":"265-269"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86488104","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}

Six switches can be used in the proposed configuration as compared to eight switches in conventional SPMC, by removing two unused switches for buck or boost rectifier operation.

The operation of both buck and boost rectifier are observed and variation of output voltage with modulation index is analyzed. To synthesis the output pulse width modulation (PWM) technique is used. Buck and boost rectifier circuits are modeled using MATLAB/Simulink and selected simulation results are shown in this paper.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"146 1","pages":"361-365"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77628361","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 compensators for the two feedback loops are designed and verified using MATLAB and Simulink. The simulation results for a 1kVA SPWM inverter are presented.

The technological developments require a compact and efficient drive to meet the challenging strategies in operation of the system. This paper provides a speed sensorless control of an Induction motor with a model based adaptive controller with stator current vectors. The purpose of the proposed control scheme is to create an algorithm that will make it possible to control induction motors without sensors. A closed loop estimation of the system with robustness against parameter variation is used for the control approach. A Model Reference Adaptive System (MRAS) is one of the major approaches used for adaptive control. The MRAS provides relatively easy implementation with a higher speed adaptation algorithm. MRAS proposed in this paper owing to its low complexity and less computational effort proposes a feasible methodology to control the speed of an Induction Motor (IM) drive without using speed sensors. Simulations results validate the effectiveness of this technique.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"283 1","pages":"377-382"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80193916","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}

They cause damage to the insulation and leads to the failure of dielectric much before the expected lifetime. PD can be used as diagnostic tool for identifying the defects in power equipment. Two challenging issues are investigated in this work. The first issue is the feature extraction using statistical operator approach for obtaining representative attributes from the original PD measurement data. The second issue is to use the Extension Theory Pattern Recognition Algorithm for identifying various types of PD sources. The proposed method does not include any process learning or tuning of parameters, and it is easily implemented using MATLAB software in this paper.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"82 1","pages":"409-412"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86158962","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}

Apart from being a very good insulator, SF6 is a potential greenhouse gas with a global warming potential of 22 800 over a period of 100 years. Therefore its leakage to the environment should be strictly monitored. And also partial discharge in the SF6 filled switchgear chambers can reduce the life and quality of insulation. The partial discharge detection should be done at the early stage to prevent the quality degradation and ultimate failure of the system. Therefore it becomes very essential to monitor the leakage and partial discharge detection in a GIS. In this work, we are proposing new methodology to detect both SF6 leakage and SF6 decomposition due to partial discharge using a MEMS sensor that detects gas at room temperature.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"31 11 1","pages":"304-307"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78634148","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 inverter is composed of a series connection of the suggested basic unit and it generates only positive levels at its output. Hence an H-bridge is further added to the proposed basic unit. The proposed topology has the main advantage of reduction in the count of power switches and driver circuits required to drive them that helps to lower the cost and ultimately the overall installation space. The proposed structure also has less dc voltage sources and driver circuits, when it is compared to the other inverter topologies. At the output voltage, the final inverter structure is able to produce all the voltage levels (positive as well as negative). The simulation is performed for verifying the operation of the inverter for a three cascaded stages of the basic unit that generates 37-levels at its output.","PeriodicalId":6644,"journal":{"name":"2015 International Conference on Power and Advanced Control Engineering (ICPACE)","volume":"33 1","pages":"64-69"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83980745","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}
