Exa Corporation was a developer and distributor of computer-aided engineering (CAE) software. Its main product was PowerFLOW, a lattice-boltzmann derived implementation of computational fluid dynamics (CFD), which can very accurately simulate internal and external flows in low-Mach regimes. [1]
A unified power flow controller (UPFC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. It uses a pair of three-phase controllable bridges to produce current that is injected into a transmission line using a series transformer. [ 1 ]
Advanced FLOW engineering (aFe) is a manufacturer company founded in 1999 and headquartered in Corona, California, United States, in two facilities: the 77,000 sq ft (7,200 m 2) headquarters and manufacturing facilities; and the 87,000 sq ft (8,100 m 2) warehouse and R&D facility, which was added in 2012.
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.
The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate.
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.
Analysis software for lightning protection used on a power substation. 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.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
