2. Transfer switch - Wikipedia

   en.wikipedia.org/wiki/Transfer_switch

   When utility power returns for a minimum time, the transfer switch will transfer the house back to utility power and command the generator to turn off, after another specified amount of "cool down" time with no load on the generator. A transfer switch can be set up to provide power only to critical circuits or to entire electrical subpanels ...

3. Generator interlock kit - Wikipedia

   en.wikipedia.org/wiki/Generator_Interlock_Kit

   Conversely, when the generator backfeed circuit breaker is turned on, the main circuit breaker is blocked and will remain off. The generator backfeed circuit breaker is connected to a generator inlet installed (preferably) on the outside of the structure. A short cord connects the generator to the house inlet, usually through a twistlock plug ...

4. Droop speed control - Wikipedia

   en.wikipedia.org/wiki/Droop_speed_control

   Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...

5. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   An induction generator draws reactive excitation current from an external source. Induction generators have an AC rotor and cannot bootstrap using residual magnetization to black start a de-energized distribution system as synchronous machines do. Power factor correcting capacitors can be added externally to neutralize a constant amount of the ...

6. Automatic generation control - Wikipedia

   en.wikipedia.org/wiki/Automatic_generation_control

   An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load.

7. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   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]

9. Chopper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Chopper_(electronics)

   Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching element is either fully on or fully off, its losses are low and the circuit can provide high efficiency. However, the current supplied to the load is discontinuous and may ...
