  • Fast Load Shedding
  • Under-frequency Load Shedding
  • Under-Voltage Load Shedding
  • Overload Load Shedding (for generators, transformers, lines, etc…)

Key Benefits

Facility Challenges

Industrial facilities often have multiple sources of power to support their operational needs which can include on site generation as well as power being supplied by the utility. When a plant experiences a loss of one of these power sources, the remaining power generation may not be able to support the existing plant loading and result in an unplanned shutdown. These unplanned shutdowns can have a very significant impact in the plant’s productivity and availability, causing significant losses in revenue when they occur.

Additionally, economical and/or grid compliance can require a facility to shed loads. Participating in Demand Response scenarios or limiting the Peak energy consumption of a facility can greatly impact the financial impact of plant operations.

GE’s PowerNode: Load Shedding Solution

GE’s PowerNode: Load Shedding (LS) solution provides a platform with real-time operation capabilities to combine all load shedding functions together with advanced monitoring and control.

Fast Load Shedding: Subcycle (<15ms) remedial action scheme that prevents the electrical system from collapsing when there is a lack of available power due to a sudden loss of power sources in the industrial facility.

Electrical Stability Load Shedding: Customized load shedding solutions based on power, frequency or voltage moving out of acceptable limits. Scenarios executed by the Load Shedding controller can operate with times from 100ms to several seconds after the power instability was detected by the protection relays.

Demand Response: Due to the increasing instability of the grid caused by renewable integration, grid operators are increasing the pressure on industrial consumers to participate in load demand control scenarios. Demand Response solutions can help facilities generate revenue through market participation as well as comply with grid requirements.

Peak Shaving: Focuses on intelligently limiting utility peak power consumption to reduce a facilities electricity bill.

GPG

GPG RT Controller

P&C relays send load/infeed power measurements and their availability to the Load Shedding controller using IEC 61850 GOOSE messages or other legacy protocols.

GE’s Load Shedding controller receives notification of a loss of an infeed from the P&C relays using IEC 61850 GOOSE messages.

Based on the priorities set by the operator, the FLS algorithms will dynamically shed only the loads groups needed to match the amount of generation lost.

GE’s proven algorithms have been verified and validated to operate in under 15ms from the time the loss of infeed has been detected.

For additional reliability, redundant Load Shedding controllers can be used.

 

Microgrid Architecture

GE’s Load Shedding solution supports:

  • 128 Load Priorities
  • 32 Infeeds
  • 128 Load Groups
  • 1000+ Loads

Aggregator IEDs are used to group Loads when more than 128 loads are present in the installation.

Aggregator IEDs receive availability and power measures from multiple loads and group them in one of the 128 Load Groups.
