The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/Bi/s 2, while the oersted is the unit of H-field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted.
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
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 ...
Capability curve of an electrical generator describes the limits of the active and reactive power that the generator can provide. The curve represents a boundary of all operating points in the MW/MVAr plane; it is typically drawn with the real power on the horizontal axis, and, for the synchronous generator , resembles a letter D in shape, thus ...
Unlike function generators, AWGs can generate any arbitrarily defined waveshape as their output. [1] The waveform is usually defined as a series of "waypoints" (specific voltage targets occurring at specific times along the waveform) and the AWG can either jump to those levels or use any of several methods to interpolate between those levels.

high-SCR generator has more synchronizing power, making it easier to operate generators in parallel. Therefore, in practice the design of a generator is seeking an SCR that balances benefits and drawbacks for a particular application. [7] SCR is a measure of the electrical stiffness (also known as a synchronizing coefficient [8]) of the machine.
Also, the output moves in an estimate of gradient direction of input. The higher the alpha parameter, the higher is the effect of input x and the less damping is seen. A low value of beta is effective in controlling sudden surges in velocity. Also, as alpha increases beyond unity, the output becomes rougher and more uneven than the input. [3]
