Frequency Event

Subscribers can now learn in real time about Frequency disturbances caused by generating units tripping offline unexpectedly.

The grid frequency in each part of the nation’s power system (the Eastern, Western, and Texas interconnections) is carefully controlled to maintain a normal frequency of 60 Hertz (Hz). Genscape’s patent pending Frequency Events system is designed to detect generator trips and estimate the location of the event.

Subscribers can now:

• See a visual indication of where a generator has tripped offline
• Hear a audio alert indicating an event has happened
• Estimate the number of megawatts that have come offline and the approximate time of the event
• See historical frequency event data provided by Genscape (30 day limit)

FAQ

Q: Genscape only monitors some of the plants in the grid. Will this system report on plants not monitored by Genscape?

A: Yes. Any event caused by a generator that is over 300 MW in the Eastern Interconnect, ERCOT or WECC will be reported on the system.

Q: I can see on my own frequency monitoring system that the frequency has dipped very low, yet I didn’t see an event notice on Genscape?

A: Genscape’s FE system is built to detect generator trips. It does not report boundary conditions.

Q: Does Genscape’s system detect loss of load?

A: Genscape does not report loss of load.

Q: What would be reported in a blackout situation?

A: Genscape’s network of frequency monitors relies on the power grid to function. During a localized or widespread blackout, these devices will not work.

Q: Canada is part of the North American Interconnection. Does this product report events in Canada?

A: Events over 300 megawatts located in Ontario and New Brunswick (Eastern Interconnection) will be reported. Events over 300 megawatts will be reported in British Columbia and Alberta (Western Interconnection). Events in Quebec will not be reported.
