The former Oregon Electric line from Tigard to Eugene is now operated by the Portland & Western Railroad. BN donated the track from Tigard to Quinaby (a farming community north of Keizer) to the State of Oregon and sold the track to the Portland & Western. South of Quinaby, the line is still owned by BN successor BNSF and leased to P&W for ...
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
Oregon electricity production by type. This is a list of electricity-generating power stations in the U.S. state of Oregon, sorted by type and name.In 2022, Oregon had a total summer capacity of 17,243 MW through all of its power plants, and a net generation of 61,317 GWh. [2]
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
For certain types of electric motors or generators to function, the coils of the rotor must be connected to complete an electrical circuit. Originally this was accomplished by affixing a copper or brass commutator or 'slip ring' to the shaft, with springs pressing braided copper wire 'brushes' onto the slip rings or commutator which conduct the current.
The doubly fed generator rotors are typically wound with 2 to 3 times the number of turns of the stator. This means that the rotor voltages will be higher and currents respectively lower. Thus in the typical ±30% operational speed range around the synchronous speed, the rated current of the converter is accordingly lower which leads to a lower ...
The motor–generator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motor–generator will lose speed and may draw a large current when power returns or the circuit-breaker is re-closed. If the speed loss is excessive (the power outage is too long), the re-closure ...
This is a list of companies based in Oregon. Oregon is the ninth largest by area and the 27th most populous of the 50 United States. The gross domestic product (GDP) of Oregon in 2010 was $168.6 billion; it is the United States's 26th wealthiest state by GDP. The state's per capita personal income in 2010 was $44,447. [1]
