Operating states of the controller
The controller recognizes the following operating states as part of the Data Area Status (see DataAreas).
The operating states Normal, Critical, Restart, Reconnect are used to select the rise limit of the active power setpoint.
Variable | Description |
|---|---|
| The controller is correctly configured via parameters and targets and can be started with Enable = TRUE. The Demand control values can be used. |
| The controller is enabled by Enable and ready to operate. The connection conditions for Restart or Reconnect have been met and the waiting time for switching on the power generating plants has expired. |
| The controller is in a normal operating state. Grid-critical operation is not active. All conditions for a Restart or Reconnect are also fulfilled and no waiting time is active. |
| The controller detects the grid-critical state by continuously monitoring the frequency during the frequency-dependent active power adjustment P(f). The diagnostic information provides further details about the connection conditions that were not met. |
| Start-up of the power generating plant is active. The diagnostic information provides further details about the connection conditions that were not met. |
| Enabling conditions are met and the waiting time for enabling power generation is active. |
| Reconnection of the power generating plant after protective tripping is active. The Reconnect is disabled at the end of the start-up ramp. The diagnostic information provides further details about the connection conditions that were not met. |
| Enabling conditions are met and waiting time for automatic reconnection after shutdown is active. |
