2. Magnetohydrodynamic generator - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_generator

   A magnetohydrodynamic generator ( MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a ...

3. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   Diesel generator on an oil tanker. The packaged combination of a diesel engine, a generator, and various auxiliary devices (such as base, canopy, sound attenuation, control systems, circuit breakers, jacket water heaters, and starting system) is referred to as a "generating set" or a "Genset" in short. Set sizes range from 8 to 30-kW (also 8 to ...

4. Droop speed control - Wikipedia

   en.wikipedia.org/wiki/Droop_speed_control

   Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...

5. High-voltage direct current - Wikipedia

   en.wikipedia.org/wiki/High-voltage_direct_current

   A high-voltage direct current ( HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. [ 1] Most HVDC links use voltages between 100 kV and 800 kV. HVDC lines are commonly used for long-distance power transmission, since ...

7. Coupon collector's problem - Wikipedia

   en.wikipedia.org/wiki/Coupon_collector's_problem

   In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more than t boxes need to be bought ...
