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, the power/energy fed back to the grid connection point is marked with a negative sign. If the electrical power ‘rElectricalPower’ exceeds the adjustable positive minimum value ‘rMinElectricalPower_Con’, the consumers are continuously switched off (PI-controller behavior), starting with the device with the lowest priority. If the electrical power ‘rElectricalPower’ falls below the adjustable negative minimum value ‘rMinElectricalPower_Gen’, the generators are continuously switched on (PI-controller behavior), starting with the device with the highest priority. Without further wiring to the inputs ‘xFb’, ‘xAlarm’ and ‘udiOpHours’ and the initial parameter settings, device 1 is assigned priority 1 (= highest) and device 4 is assigned priority 4 (= lowest) for each respective group. For each functionality (switching off consumers, switching on generators) an internal function block ‘Redundance4’ from this library exists, where an adjustable number of consumers (‘wActiveNumberOfDevices_Con’) and generators (‘wActiveNumberOfDevices_Gen’) are used. The detailed description of this function block can be found there. The enable / disable of the function block is controlled via the input ‘xEn’; in the disabled state all outputs assume defined states. Devices with the index ‘_Con’ are consumers, devices with the index ‘_Gen’ are generators.

Input xEn

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

Input xUpdateDeviceOutputs

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

Input xResError

Every rising edge at this input triggers a reset of all fault outputs (‘sErrorCodes_General’, ‘sErrorCodes_Con’ and ‘sErrorCodes_Gen’) to the fault-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-in by a negative sign. The electrical power is then time-filtered (four parameters with the index ‘_EP’) and is available for the internal control processes.

Input rMaxElectricalPower_Con

This input sets the current maximum value of electrical power consumption. If the current electrical power at input ‘rElectricalPower’ exceeds this maximum value, consumers are continuously switched off according to their nominal power, starting with the consumer with the lowest priority. The control behavior of the used PI controller can be influenced by the parameter ‘rTn_Con’ (= reset time).

Input rMaxElectricalPower_Gen

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

Input wActiveNumberOfDevices_Con

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

Input wActiveNumberOfDevices_Gen

This input sets the number of generators used in the range 0 - 4. It is directly connected to the internal function block ‘Redundance4_Gen’ (input ‘wActiveNumberOfDevices’).
