From 1996 to 1999, the FERC made a series of decisions which resulted in the restructuring of the U.S. electric utility industry. The FERC's intention in doing so was to open the wholesale power market to new players, with the hope that spurring competition would save consumers $4 to $5 billion per year and encourage technical innovation in the industry.
The IBM 9020 was an IBM System/360 computer adapted into a multiprocessor system for use by the U.S. FAA for Air Traffic Control. [1] Systems were installed in the FAA's 20 en route Air Route Traffic Control Centers (ARTCCs), beginning in the late 1960s. [2]: 6 The U.K. CAA also installed a system in its London centre. [3]
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.
The combined transmission and distribution network is part of electricity delivery, known as the power grid. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power ...
The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.
The Common Information Model (CIM) is an electric power transmission and distribution standard developed by the electric power industry. It aims to allow application software to exchange information about an electrical network. [1] It has been officially adopted by the International Electrotechnical Commission (IEC).
Any IEEE 1901 products can coexist and be fully interoperable between products using the same technology. On the other hand, medium-frequency home control devices remain divided, although X10 tends to be dominant. For power grid use, IEEE has approved a low-frequency (≤ 500 kHz) standard called IEEE 1901.2 in 2013. [25]
The 1930s and 1940s saw a large number of different John Deere models emerge, as small farmer.s emerging from their Depression troubles increasingly turned from horses to tractors. Deere & Company's GM model was introduced in 1942, and was made until 1947. Engine power was increased to 38 hp (28 kW), and a new six-speed transmission was also added.
