This course presents the subject of short-circuit studies in a very structured fashion. First, a simple equivalent circuit is developed for a generic power system, system impedances are recalculated to common base and fault are calculated at various locations throughout the system. A detailed explanation is offered for calculation of three phase faults. Explained techniques can be also verified ...

In addition to large scale applications, there are a number of other applications for wind turbines, such as medium scale applications on isolated-grids and off-grid uses for pumping water and providing smaller amounts of electricity for stand-alone battery charging ...

The starting current of most AC motors is several times normal full load current. Both synchronous and induction motors can draw five to ten times full load current when starting them across the line. Motor-starting torque varies directly as the square of the applied voltage. If the terminal voltage drop is excessive, the motor may not have enough starting torque to accelerate up to running ...

When determining between AIS or GIS technology, some elements alone, for example aesthetics, may be an overcoming impact on a user’s conclusion. Nevertheless, most of the time the best conclusion asks for assessing many elements and soliciting input data from many sections within an investor’s organization. It is also critical to note that the optimal substation arrangement may not be ...

The question that is frequently discussed is: “Why does anyone want to use D.C. transmission?” One reply is that electric losses are lower, but this is not true. Amount of losses is determined by the rating and size of chosen conductors. Both D.C. and A.C. conductors, either as transmission circuits or submarine cables can generate lower power losses but at increased cost since the ...

The ability of a power system, containing two or more synchronous machines, to continue to operate after a change occurs on the system is a measure of its stability. The stability problem takes two forms: steady-state and ...

Since the impedance of a transmission circuit is relative to its length, for distance measure it is suitable to use a relay able to measure the impedance of a circuit up to a present point (the reach point). Such a protection relay is known as a distance protection relay and is made to function only for faults happening between the protection relay location and the chosen reach point, therefore ...
