    1211 Words  | 5 Pages

    COCKPIT AUTOMATION A Good Servant but a Bad Master Introduction 1. With the advent of modern technology, the use of computers has become inevitable in the completion and performance of a particular task. While automation has proven to improve the speed of completion of a job, it drastically affects the "operator" whose task shifts from being the "performer" to being the "observer". This is where the issue of "complacency" sets in. With this major revolution, one may ask if the introduction of

    in an independent way. In the suggested control scheme, the power calculation and harmonic abstraction are not required since the harmonics, unbalances, disturbances, and displacement would be compensated. The SAF has a current loop in order to make sure a sinusoidal grid current synchronized with the grid voltage. The PAF has a voltage loop in order to ensure a balanced controlled load voltage with small harmonic distortion. The SAF and PAF control loops are independent from each other since they

  • Ohm's Law Lab Report

    1206 Words  | 5 Pages

    Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current and Voltage Laws, which govern the currents entering and exiting a circuit node

    ability to transmit electricity for larger distances much quicker, AC is far more superior to Direct Current(DC). To expand on that, Direct Current can only transmit electricity in one direction every mile, whereas AC can transmit electricity for larger distances and much quicker. Also, Direct Current’s disability to transmit electricity farther makes it less reliable than AC. To add on to that, Alternating Current is the world’s most dominant source for transmitting electricity because of its reliability
