LIVE MQTT TELEMETRY

Connected Devices

Live readings from individual FlexGrid controllers. Each unit is identified by its unique MQTT device ID.

LIVE MEASUREMENTS

FREQUENCY RESPONSE DEMONSTRATION

Rapid frequency-drop simulator

Explore how FlexGrid repeats sequential 10% cycle-limiting stages until the selected base frequency is restored.

SIMULATION ONLY · NO LIVE COMMANDS

ADJUSTABLE SCENARIO

RECURSIVE 10% MODEL

Units deployed3 million One million controllable units per response stage Base grid frequency50.00 Hz Frequency immediately before the simulated disturbance Generation shortfall3,000 MW Rapid loss of available grid generation Stage interval1.00 s Delay between each sequential 10% stage action

Illustrative model: each million-unit stage reduces load in 10% increments. The sequence repeats from Stage 1 until the base frequency is restored or every deployed stage reaches 90% cycle limiting.

Calibration load control

Use only while completing the reference procedure.

STEP 1

Capture zero reference

Ensure 0 mA is flowing through the shunt resistor.

STEP 2

Capture 5 mA reference

Apply an accurate 5 mA reference through the shunt resistor.
