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.
An optimal power-flow study establishes the best combination of generating plant output to meet a given load requirement, so as to minimize production cost while maintaining desired stability and reliability; such models may be updated in near-real-time to allow guidance to system operators on the lowest-cost way to achieve economic dispatch.
Load flow study is an important tool involving numerical analysis applied to a power system. The load flow study usually uses simplified notations like a single-line diagram and focuses on various forms of AC power rather than voltage and current. It analyzes the power systems in normal steady-state operation.
The Westinghouse Anacom was an AC-energized electrical analog computer system used extensively for problems in mechanical design, structural elements, lubrication oil flow, and various transient problems including those due to lightning surges in electric power transmission systems. The excitation frequency of the computer could be varied.
load flow study A mathematical prediction of the flow of electric power in a network, based on a model of the actual or proposed system; necessary for planning of electrical grids. load following power plant A power plant that can economically be operated over a significant range of output, so as to meet varying electric power demand. load-loss ...
Power engineering software is a software used to create models, analyze or calculate the design of Power stations, Overhead power lines, Transmission towers, Electrical grids, Grounding and Lightning [clarification needed] systems and others. It is a type of application software used for power engineering problems which are transformed into ...
Power flow is increased by adding a series capacitor to offset line inductance or decreased by adding a series load-flow reactor to add to the line inductance. One type of series compensation is the Thyristor-Controlled Series Capacitor (TCSC) , which combines the TCR from an SVC in parallel with a traditional fixed series capacitor.
In electrical power systems a slack bus (or swing bus), defined as a Vδ bus, is used to balance the active power | | and reactive power | | in a system while performing load flow studies. The slack bus is used to provide for system losses by emitting or absorbing active and/or reactive power to and from the system.
