A pilot project of DA based on Geographic Information System (GIS) is conducted and some effective measures for improving the system are discussed considering the problems in practice. Due to the large quantity of distribution devices and frequent changes, a system interface to achieve graphics - models integration could be utilized to solve the data maintenance problem for DA and ensure its applicability. An integrated data maintenance procedure for GIS and DA is proposed to increase the data accuracy and timeliness. Research on the operation and maintenance technologies, functional improvement, as well as advanced application software development for DA system (DAS) are conducted, and a customizable DAS is built to satisfy different needs of distribution application. The results are successfully applied to a large city distribution networks, which illuminates its high theoretical and practical engineering value.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125407360","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}

So the transformer protection is an essential part of the system maintenance and protection. This paper presents a new method for locating transformer winding faults specially short circuit faults such as turn-to-turn, turn-to-core, turn-to-earth, turn-to-transformer body, and primary winding to secondary winding. In this study a dynamic model of transformer is simulated. The current and voltage signals of input and output terminals of the transformer are measured for different kinds of faults. The Fourier transform of all of the measured signals are calculated. Then the harmonics of all of the simulated faults are extracted and saved as special indexes in a database and the fault locating process is completed by the pattern recognition. And in the last step, the pattern recognition determines the fault's location.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115572373","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}

For busbar protection with IEDs and MUs using IEC61850-9-2 process bus, communication traffic jams are the main concern, due to transferring 80 samples/cycle data from all bay MUs to IED via 100BASE-FX. This paper describes peer-to-peer connection between MUs and IED in order to segrigate the SV messages of 32 bays on the process bus. As a LAN switch is not necessarily required in the process bus, higher reliability, long lifetime, interoperability and easy-maintenance can be achieved. The sampling timing of each MU is controlled from IED by 1PPS signal which is independent from the time stamp signal made by GPS so that lock out of busbar protection is prevented even at the case of GPS clock loss. This technique can be applied not only to busbar protection but also to VSS (voltage selection scheme).","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"388 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116226019","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 algorithm consists of two stages: phasor estimation and frequency estimation. First, the input signal is decomposed into two components using the dynamic phasor method. Then, the two components are combined to estimate the frequency. To evaluate the performance of the proposed algorithm, amplitude change and frequency change are considered for generating test signals. The performance of the algorithm is also assessed for dynamic conditions in a single machine power system. The Electromagnetic Transients Program was used to generate voltage signals for a load increase and single phase-to-ground faults. The performance evaluation showed that the proposed algorithm accurately estimated the fundamental frequency of power system signals in the presence of amplitude modulation and frequency change. When compared with other algorithms, simulation results show that the proposed algorithm has lower frequency estimation error. Improved algorithm is expected to increase the reliability of the measurement under fault conditions.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116393651","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}

It can be analyzed that different network configuration and specific fault location have great influence for the shortest transmission path of initial traveling wave, and therefore affecting the configuration of traveling wave fault location unit. Primarily, setting each line as fault line respectively, the complicated network can be converted into simplified one by using Floyd algorithm, which keeps the fault line in any case. The nodes can be divided into two arrays according to the fault location in simplified network. In the case of different fault line, minimum sharing set can be calculated by the nodes from two arrays, and thus the nodes need to configure traveling wave fault location can be decided. When the fault occurs on special condition, which will detail below, the relevant scheme is suggested. The simulation results illustrate the reliability and feasibility of the algorithm.","PeriodicalId":435652,"journal":{"name":"2011 International Conference on Advanced Power System Automation and Protection","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116494695","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}
