Function description

General

This function block is used to limit (control) the electrical power at the grid connection point ‘rElectricalPower’ to adjustable maximum values. The power / energy drawn from the grid connection point is marked with a positive sign, and the power / energy fed back into the grid connection point is marked with a negative sign. If the electrical power ‘rElectricalPower’ exceeds the adjustable positive maximum value ‘rMaxElectricalPower_Con’, the consumers are continuously switched off, starting with the active device with the lowest priority. If the electrical power ‘rElectricalPower’ falls below the adjustable negative maximum value ‘rMaxElectricalPower_Gen’, the generators are continuously switched on, starting with the device with the highest priority (PI controller behavior). Without any additional wiring at inputs ‘xFb’, ‘xAlarm’ and ‘udiOpHours’ and with the initial parameter settings, device 1 is assigned priority 1 (= highest) and device 4 is assigned priority 4 (= lowest). For each functionality (switching off consumers, switching on generators) there is internally a separate function block ‘Redundance4’ from this library, in which an adjustable number of consumers (‘wActiveNumberOfDevices_Con’) and generators (‘wActiveNumberOfDevices_Gen’) is used. The detailed details of this function block are described there. The enable / disable of the function block is done via the input xEn, in the disabled state all outputs assume defined states. The devices with the index ‘_Con’ are consumers, and the devices with the index ‘Gen’ are generators (= generator). Signal flow: The current actual value 'rElectricalPower' is fed to temporal filtering (four parameters with index '_EP' ) and to the selected controllers. Depending on the selected controller (parameter 'eControlSelect'), the difference between the actual value at input 'rElectricalPower' and the corresponding maximum value 'rMaxElectricalPower_Con' / 'rMaxElectricalPower_Gen' is formed (gain factor = 1.0 constant) and then passed to the logic for selecting the consumers / generators. Each device is represented by the elements of a structure variable 'stOutputs_ConX' or 'stOutputs_GenY'. The element 'rPowerSignalkW' always contains the maximum possible power of the device. The element 'xCmd_Redundance4' contains the enable of the device from FB '‘Redundance4’'. The element 'xCmd' contains the enable of the device from the signal flow; it also includes the disabling of the device (xCmd = FALSE).

Input xEn

This input is used to enable / disable the function block; in the disabled state all outputs assume defined states.

Input xUpdateDeviceOutputs

Each rising edge on this input triggers an update of all device outputs (outputs ‘stOutputs_XXXX’).

Input xResError

Each rising edge on this input triggers a reset of all error outputs (‘sErrorCodes_General’, ‘sErrorCodes_Con’ and ‘sErrorCodes_Gen ‘) to the error-free state.

Input rElectricalPower

The current electrical power at the grid connection point is available at this input. Power drawn is indicated by a positive sign, feed-back by a negative sign. The electrical power is then filtered over time (four parameters with the index _EP’) and is then available for the internal control processes.

Input rMaxElectricalPower_Con

The current maximum value of electrical power draw is set at this input. If the current electrical power at input ‘rElectricalPower’ exceeds this maximum value, the consumers are continuously switched off, starting with the consumer with the lowest priority, depending on their nominal power. The control behavior of the PI controller used can be influenced by parameter ‘rTn_Con’ (= reset time, if PI controller is selected).

Input rMaxElectricalPower_Gen

The current maximum value of electrical power feed-back is set at this input. If the current electrical power at input ‘rElectricalPower’ falls below this maximum value, the generators are continuously switched on, starting with the generator with the highest priority, depending on their nominal power. The control behavior of the PI controller used can be influenced by parameter ‘rTn_Gen’ (= reset time, if PI controller is selected).

Input wActiveNumberOfDevices_Con

At this input, the number of consumers used in the range 0 - 4 is set. It is directly connected to the internal function block ‘Redundance4_Con’ (input ‘wActiveNumberOfDevices’).

Input wActiveNumberOfDevices_Gen
