Ripple Control

In the Ripple Control mode, the system receives control signals from the grid through dry contact signals, and performs power control as required.

If the Ripple Control mode is selected, the grid operator will convert the dispatch signals into the dry contact signals for transmission. A total of 16 DI combinations are available, each with a specific power ratio. Please set the DI combination for the system so that it can receive and respond to grid signals properly.

Note: Each DI combination must be unique.

Procedure

  1. Navigate to DI Power Control page.
  2. Set the DI Control Method to Ripple Control.
  3. Set the Inverter Output Power Limit Ratio Calculation Basis.
    • Nominal Power: The dispatch value is calculated based on the rated power of the inverter that is connected.
    • Installed PV Power: The dispatch value is calculated based on the installed PV power of the inverter that is connected. Please enter the Total Installed Power of Modules based on the actual plant conditions.
  4. Select DI ports, and set a power ratio in a range of 0-100%.
    Note: Set DI combinations based on the control signals sent from the grid operator.
  5. Click Add DI Combination to add other DI combinations.
  6. Click Apply Settings.
