2. Standby generator - Wikipedia

   en.wikipedia.org/wiki/Standby_generator

   Standby generators. A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]

3. Operating reserve - Wikipedia

   en.wikipedia.org/wiki/Operating_reserve

   An idealized representation of the four kinds of reserve power and the time intervals after an unexpected failure that they are in use. [1]In electricity networks, the operating reserve is the generating capacity available to the system operator within a short interval of time to meet demand in case a generator goes down or there is another disruption to the supply.

4. Generator interlock kit - Wikipedia

   en.wikipedia.org/wiki/Generator_Interlock_Kit

   Early generator interlock kits consisted of two sliding steel or plastic (depending on the brand) plates held together by three bolts and installed on the front cover of the home's breaker panel, however, some models made by Eaton (formerly Cutler-Hammer) and Siemens for panels manufactured by them install on the adjacent circuit breakers themselves and consist of a sliding arm for breakers ...

5. Emergency power system - Wikipedia

   en.wikipedia.org/wiki/Emergency_power_system

   A backup generator for a large apartment building A backup power fuel cell for telecom applications A portable emergency power generator in a shipping container. An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply.

6. Black start - Wikipedia

   en.wikipedia.org/wiki/Black_start

   A typical BS generator is a small (10-50 MW) hydro or gas turbine generation unit. [ 20 ] The output of variable renewable energy (VRE) sources is not predictable, this makes them difficult to use for black start or support in the grid restoration , as the lack of control, inherent in VRE sources, might cause a weak grid emerging from a ...

7. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   Newer rotary units use technologies such as magnetic bearings and air-evacuated enclosures to increase standby efficiency and reduce maintenance to very low levels. Typically, the high-mass flywheel is used in conjunction with a motor-generator system. These units can be configured as: A motor driving a mechanically connected generator, [7]
