Unused capacity available from units connected to and synchronized with the grid to serve additional demand. The spinning reserve must be under automatic governor control to instantly respond to system requirements.
Spare synchronised generation reserve that is available to the grid in case a generator is suddenly and unexpectedly lost. SR may be either partly loaded spinning reserve ( PLSR) which is simply a generator that is running and generating, but at a lower output that allows it to increase output quickly in response to low frequency. Some hydro generators can also provide tail-water depressed ( TWD) spinning reserve. In this case a hydro generator and turbine are run as a motor from the grid, which means the generator is spinning and synchronised. It can quickly be turned back into a generator in response to low frequency.
Spinning Reserve refers to the amount of spare generation capacity available in the system at any one moment.
Reserve generating capacity running at a zero load and synchronized to the electric system.
Reserve generating capacity that is immediately available to meet unexpected power needs. Referred to as “spinning” because the generating units are on-line and available to serve additional load immediately.
the portion of unloaded synchronized generating capacity, controlled by the ISO, which is capable of being loaded in 10 minutes, and which is capable of running for at least two hours
The amount of unloaded generating capability of a participant connected to and synchronized with the interconnected system of the participants and ready to take load. Spinning reserve allocation to any generator shall not exceed the amount of generation increase that can be realized in 10 minutes.
Spinning reserve is provided by generating units that are on-line and loaded at less than maximum output. They are available to serve load immediately in an unexpected contingency, such as an unplanned outage of a generating unit.
the amount of Operating Reserve synchronized to the system, responding automatically through governor action to fluctuations in system frequency and is capable of assuming load within 10 minutes.
The reserve generating capacity running at zero load and synchronized to the electrical system
Electric power plant or utility capacity on line and running at low power in excess of actual load.
Unused capacity available from units connected to and synchronized with the grid to ser ve additional demand. Forms a part of the Operating Reserve.
