The hybrid reactive power compensations, using distributed generation and switched shunt capacitors in the coordinated manner, are implemented to deal with the change of power factor in the network.

The power factor control performances are demonstrated under various operating scenarios using the test system implemented in DIgSILENT PowerFactory.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":"573 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125967399","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 the meantime when the ground grids of the two substations are electrically disconnected, the auxiliary grounding system of substation can create steep ground potential rise between the ground grids of the two substations and hence introduces a risk for those who are working nearby. It is therefore important to incorporate safety criteria described in terms of step and touch voltage into electrical designs without any potential electrical hazards. The safety design planning process is illustrated by the Pathumwan (PM) substation of Metropolitan Electricity Authority (MEA). Modeling and simulation is carried out on the Current Distribution Electromagnetic interference Grounding and Soil structure (CDEGS) program. A sequential transition process from the small substation to a permanent substation is suggested to comply with the IEEE standard 80-2000.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126534129","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 historical data of circuit breakers installed since 1989 to 2011 at three voltage levels as 115 kV, 230 kV and 500 kV are analyzed. The data has been classified into different types of circuit breakers and components. The main components are classified as major HV components, operating mechanism, and control circuit and others whereas the sub-components are also differentiated. The failure frequencies of those sub-components are then assessed in order to observe their failure characteristics in form of Bath-tub pattern, which is classified into three zones as teething, random and ware-out zone. The results show failure frequency of sub-components of only 115 kV circuit breakers. Finally, the preventive maintenance for the circuit breakers can be effectively managed due to actual failure behavior. Consequently, the failure rate of the equipment can be reduced resulting in better power system reliability.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122174896","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}

An application informing about the location and the estimated arrival time of an electric vehicle for Android smart phones is developed and tested. Passengers can view the current location of a particular electric vehicle and the estimated arrival time. Additionally, an alert system has been set up so that the passengers can be notified if a particular vehicle is coming to the bus stop. After testing such application, it is found that 90 percents of passengers using the application does not miss the vehicle while almost 50 percents of the passengers not using the application could not get the vehicle in time.
