Distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison.
Single-phase power may be used for electric railways; the largest single-phase generator in the world, at Neckarwestheim Nuclear Power Plant, supplied a railway system on a dedicated traction power network.
Combination of an electrical generator and an engine mounted together to form a single piece of equipment.
Most of the portable units available are single-phase generators and most of the three-phase generators manufactured are large industrial type generators.
Small wind turbines, also known as micro wind turbines, are used for microgeneration of electricity, as opposed to large commercial wind turbines, such as those found in wind farms.
The generators for small wind turbines are usually three-phase alternating current generators and the trend is to use the induction type, although some models utilize single-phase generators or direct current output.

The converters consist of a three-phase synchronous motor and a single-phase synchronous generator.
Hydroelectric power station in Bavaria, Germany.
Through six, 450 m ducts connecting the two natural lakes, the water flows to the hydro-electric plant's four Pelton water turbines with single-phase generators, and four Francis water turbines with three-phase generators, and then exits into the Kochelsee.
Traction power grid operated by Amtrak along the southern portion of its Northeast Corridor : the 226.6 route miles (362 km) between Washington, D.C. and New York City and the 104 route miles (167 km) between Philadelphia and Harrisburg, Pennsylvania.
Safe Harbor Dam, PA – The Safe Harbor Dam has two 28 MW, single phase, turbines dedicated to 25 Hz power generation. A 25 MW bi-directional motor generator type frequency converter is also installed. The total 25 Hz capacity of the dam is 81 MW. Power from Safe Harbor is transmitted via the Conestoga substation to Royalton, Pennsylvania, Parkesburg, Pennsylvania (two circuits), and Perryville, Maryland (four circuits) where it is fed into the lineside 138 kV network.
Concrete gravity dam, with an associated hydroelectric power station, on the lower Susquehanna River.
Units 1 and 2 are Kaplan turbines connected to single-phase generators to produce 25 Hz single-phase electric power for railroad use by Amtrak and SEPTA, but also can be connected to a motor-generator to convert any spare 25 Hz power to 60 Hz. The rest of the units generate 60 Hz, three-phase power.
One of the first commercial system to produce and transmit alternating current (AC) electricity for industrial use and one of the first AC hydro-electric plants ever constructed.
The system consisted of two identical 100-hp Westinghouse single-phase alternators (the largest the company made at the time).
Nuclear power plant in Neckarwestheim, Germany, sometimes abbreviated GKN , operated by EnBW Kernkraft GmbH, a subsidiary of EnBW.
The traction current generator is the world's largest single-phase AC generators.
Polyphase coils are electromagnetic coils connected together in a polyphase system such as a generator or motor.
Compared to single-phase motors and generators, polyphase motors are simpler, because they do not require external circuitry (using capacitors and inductors) to produce a starting torque.
