Are higher maxima possible?

The system can also be modified for larger outputs than 10 MW.

For more detailed information:

• Conversion to larger maxima, resolution, accuracy: In the controller, the power setpoints are considered 16-bit values (unsigned) and the work calculations are 32-bit values throughout. The PC input surfaces for the setpoints are basically 32-bit values.

• The standard software of the U1500 can manage setpoints from 1 to 11900 kW, where the resolution for the setpoint input here is 1 kW and the system-internal resolution for the work calculation (after all, the system converts the setpoints into maximum available work in a measurement period and then manages the work allocation for the individual resources) is 1 kWs*100, i.e. one kilowatt hundredth of a second. If a customer wants to cover higher setpoints, we switch the resolution to the second "setpoint range" via a define in the control program and in the user interface. This ranges from 11900 kW to 119000 kW, i.e. 119 MW. The resolution for the setpoint input is then 10 kW (0.01 MW) and the working resolution is 1 kWs*10, i.e. one kilowatt tenth of a second.

• Using the same procedure, a third "setpoint range" of 119000 kW to 1190000 kW, i.e. 1190 MW, is possible, where the resolution at setpoint input is 100 kW (0.1 MW) and the internal working resolution is 1 kWs, i.e. one kilowatt second. Depending on the factory-set resolution, the input of setpoints in the PC interface is limited to 11900, 119000 or 1190000 kW (default is 11900 kW).

• These limits have a safety reserve of 100%, so that maximum power measurements up to twice the setpoint limit are possible without memory overflow. If the transformer factor and pulse valency are below a certain characteristic curve (usual ratios), four times the maximum power measurement is possible in the individual setpoint ranges.
