2. Load factor (electrical) - Wikipedia

   en.wikipedia.org/wiki/Load_factor_(electrical)

   In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...

3. Power-flow study - Wikipedia

   en.wikipedia.org/wiki/Power-flow_study

   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.

4. Electrical load - Wikipedia

   en.wikipedia.org/wiki/Electrical_load

   An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]

5. Per-unit system - Wikipedia

   en.wikipedia.org/wiki/Per-unit_system

   In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t

6. Single-line diagram - Wikipedia

   en.wikipedia.org/wiki/Single-line_diagram

   A bus corresponds to a location where the power is either injected into the system (e.g., a generator) or consumed (an electrical load). [3] A steady-state of each bus can be characterized by its voltage phasor; the system state is defined by a vector [4] of voltage phasors for all the buses. [5]

7. Load-loss factor - Wikipedia

   en.wikipedia.org/wiki/Load-loss_factor

   Multiple empirical formulae exist that relate the loss factor to the load factor (Dickert et al. in 2009 listed nine [5]). Similarly, the ratio between the average and the peak current is called form coefficient k [ 6 ] or peak responsibility factor k , [ 7 ] its typical value is between 0.2 to 0.8 for distribution networks and 0.8 to 0.95 for ...

9. Short circuit ratio (electrical grid) - Wikipedia

   en.wikipedia.org/wiki/Short_circuit_ratio...

   In an electrical grid, the short circuit ratio (or SCR) is the ratio of: the short circuit apparent power (SCMVA) in the case of a line-line-line-ground (3LG) fault at the location in the grid where some generator is connected, to: the power rating of the generator itself (GMW).
