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 Vernova’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 Vernova’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.

GE Vernova’s Load Shedding solution supports:

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.

The GPG RT Controller is a real-time controller that hosts GE Vernova’s Load Shedding solution and other power system control applications. The GPG RT Controller has been designed to be compliant with IEC 61850-3, which is an international hardware standard for communication networks and systems in power substations. Supporting international cybersecurity standard, the GPG RT Controller is the backbone of GE Vernova’s industrial power solutions that ensure reliable and secure operation for improving the reliability of industrial power networks.

• A, V, W, var, VA, PF, Hz, Wh, varh, demand
• Torque, temperature (12 RTDs)
• Event recorder
• Oscillography & Data Logger (trending)
• Statistical information & learned motor data

Monitoring & Metering

The 469 includes high accuracy metering and recording for all AC signals. Voltage,current, RTD and power metering are built into the relay as a standard feature.

Metering

The following system values are accurately metered and displayed: Phase, differential and ground currents, average current, motor load, current unbalance. Phase-to-ground and Phase-to-phase voltages, average phase voltage, system frequency. Real, reactive, apparent power, power factor, watthours, varhours, torque Current and power demand. Analog inputs and RTD temperatures. Thermal capacity used, lockout times, motor speed

Monitoring

The 469 is equipped with monitoring tools to capture data. The following information is presented in a suitable format.

Event Recorder

The event recorder stores motor and system information with a date and time stamp each time a system event occurs. Up to 256 events are recorded.

Oscillography

The 469 records up to 128 cycles with 12 samples per cycle of waveform data for 10 waveforms (Ia, Ib, Ic, Ig, Diffa, Diffb, Diffc, Va, Vb, Vc) each time a trip occurs. The record is date and time stamped.

Advanced Motor Diagnostics

The Multilin 469 provides advanced motor diagnostics including a broken rotor bar detection function. The broken rotor bar detection is a condition maintenance function that continuously monitors the motor’s health while in operation. The advanced Motor Current Signature Analysis (MCSA) continuously analyzes the motor current signature and based on preset algorithms will determine when a broken rotor bar is present in the motor.
