tailieunhanh - PhD. Thesis in brief: A study of intelligent methods for fault classification and fault location on the transmission line

The thesis contributes on quick solving a big amount of work, which is in fault classification and location at the request of the Power Sector. Besides, the thesis supplies the knowledge supporting for operation, increasing the effectiveness of relay’s utilization. | MINISTRY OF EDUCATION AND TRAINING DA NANG UNIVERSITY VU PHAN HUAN A STUDY OF INTELLIGENT METHODS FOR FAULT CLASSIFICATION AND FAULT LOCATION ON THE TRANSMISSION LINE SPECIALIZATION POWER SYSTEM amp NETWORK CODE PHD. THESIS IN BRIEF Da Nang - 2014 This thesis has been finished at Danang University of Technology Da Nang University Supervisor Assoc Prof. PhD. Le Kim Hung Examiner 1 Assoc Prof. PhD. Phan ThiThanh Binh Examiner 2 Prof. Dr. Tran Đinh Long Examiner 3 Assoc Prof. PhD. Nguyen Hong Anh The will be defended at the Thesis Assessment Committee at Da Nang University Level at Room No . . . At date month 2014 The thesis is available at 1. The National Library. 2. The Information Resources Center University of Danang. 1 INTRODUCTION 1. THE REASON FOR CHOOSING THE THESIS Fault location methods on EVN s transmission line which is based on the experimental operation and relay protection using measurement data at one overhead line . Therefore it meets many difficulties in locating faults increasing time electric losts economics damages. Thus the thesis a study of intelligent methods for fault classification and fault location on the tranmisstion line has scientific meaning and application in managing electrical operations. 2. THE CONTENT AND PURPOSES OF THE RESEARCH The content and purposes of the research such as - Systematizing methods the researches published in the fault classification and location area on the grid s power transmission. - Researching effects of main factors on the performance and calculating distance to fault of relay protection. - Assessing fault location methods of relay manufacturers which are for the diagram of transmission lines using current voltage data measurement at one two or three ended of the transmission line. - The research uses intelligent methods in order to classify and locate transmission line s faults. 3. RESEARCH METHODS The thesis combines two methods theory research and experimental research. 4. THE .
