When a short-circuit fault occurs on a transmission line, it should be located rapidly and correctly in order to repair the faulted section, minimize the transmission line outage time, and restore power delivery as soon as possible. Therefore, development of a robust and accurate fault location technique under various fault conditions is a highly important research area.
In some low power densities areas, utilities are connected to an existing transmission line using a tapped line because of economic advantages. Such a configuration of transmission lines presents great difficulty in the task of fault location when the fault resistance is not negligible due to the infeed currents from different sources.
So far, different fault location algorithms for three-terminal transmission lines have been developed [1–18]. Several algorithms assume data to be available at local terminal known as one-ended fault location techniques [1-3]. Infeed currents and fault resistances are sources of errors in these fault location algorithms. Many other algorithms use data from more than one terminal. In [4] synchronized voltage and current waveforms measured at all three terminals are used to calculate the fault location. The authors utilized the prefault measurements at three terminals to synchronize the waveforms. An alternative approach is presented in [5] which similarly uses measurements from all three terminals of the transmission line but does not require synchronized data from all terminals. Using an iterative algorithm, the synchronization error is estimated and the fault location is obtained. This algorithm considers the lumped model of the transmission line in its calculations. This simplification results in increase of the estimation erro...

Essay about The Benefits of Continuously Variable Transmissions (CVT)

- Introduction We are constantly searching for ways to perform the tasks essential to our lifestyle in ways that have a smaller impact on the environment. In the United States cars are exceedingly common, nearly twenty percent of American households own three or more vehicles (U.S. Department of Energy Web). These vehicles are also one of the largest contributors to our impact on the environment. The majority of cars use automatic transmissions, although not very efficient, they offer convenience of not shifting gears....   [tags: transportation, vehicles, ]

Drivers Encountered On The Open Road Driving Automatic Transmission Essay

- In the present time most of the drivers encountered on the open road are driving automatic transmission. Many, if not most, go through their life without knowing how to drive manual transmission. The main reason being because of the necessity of using both feet and having to drive one handed. Learning how to drive both is a skill that will open a new world of opportunities. One never knows if there will ever be a situation that will require a person to know how to drive manual, also known as “stick shift”....   [tags: Manual transmission, Automatic transmission]

Analysis of a Transmission Model Essay

- Equipped with n antennas & the remote unit is equipped with m receive antennas (see Figure (1)). At each time slot t, signals C_t^i t=1,2,……n are transmitted simultaneously from the n transmit antennas. The channel is at-fading & the path gain from transmit antenna i to receive antenna j is denoted by h_(i,j) . The path gains are modeled as samples of independent complex Gaussian random variables with variance 0:5 per real dimension, i.e.,h_(i,j)~N(0,1) as we assume that signals received at di_erent antennas experience independent fading....   [tags: antena, transmission, generator matrix]

Benefits and Limitations of Distance Learning Essay

- Benefits and Limitations of Distance Learning Distance Learning Defined Technology is restructuring many aspects of education. An example of this phenomenon is distance education. Distance learning is defined as " the practice of educating learners who are separated from the teacher or trainer and each other by space, time, or both" (Moller 115). Distance education occurs in a non-classroom setting when students participate in course discussions, exercises, and receive assessment from the instructor by utilizing technology such as video conferencing, audiographics, CD-ROM, and Web-based media (Welsh 41)....   [tags: Education Educate Distance Essays]

Essay on Energy Transmission

- In energy systems where the energy-collection process in an energy-material is needed as a step physically separated from the Processing Unit, the transportation of the energy-material that contains the energy is required. In the case of biomass-based energy systems, this step encompasses all the infra-structure associated with the logistics of supplying biomass to the Processing Unit: machines, roads, pipes, etc. Although the energy that flows through this stage is tied to the amount of raw material demanded by the processing plant, its cost structure may vary freely, dependent upon the type of transportation technology adopted (i.e.: pipelines, trucks, railroads), distances, daily demand o...   [tags: Energy]
