Hello everyone,
I’m working on a project that involves managing reactive power between inverters and a static VAR Generator. Here’s a brief overview of the scenario
Reactive Power Setpoint: Received from the grid operator.
PF Setpoint: Received from the grid operator.
Voltage Setpoint: Received from the grid operator.
Which Mode to run in also received from the Grid Operator PF/VOLTAGE/Active Power/Reactive Power regulation
Inverters: Each has a specific capacity (don't have the Number yet) and can only handle up to 60% of their capacity for reactive power. The number of inverters online can vary. We can read how many inverters are online and calculate the Reactive power they can generate @60%
VAR Generator: Has a higher capacity 5MVAR and is intended to handle excess reactive power beyond what the inverters can manage.
but the Required Reactive energy is only 0.5 MVAR which is 1/10th so the Inverters can be fully Ignored.
It also has several Modes like Fixed value reactive power Mode, PF Mode Will maintain the PF, Voltage Mode will maintain the Voltage by varying the reactive Power, Maintaining Reactive Power as setpoint, and Maintaining Reactive Power of load side as set
Objective:
Distribute the reactive power setpoint between the inverters and the VAR Generator.
But the Inverters are being controlled by a Data logger/Controller- this controller uses a PI block inside and gives a command to the Inverters we cannot read this command which is being sent to the Inverters However from the Meter we can Know the PF, Voltage, Active and Reactive Power moment to moment
So How should I handle the Program for this - should the Data logger/Controller only do Active power control and the reactive power to be sent to the SVG in that case we have to calculate the Required Reactive power in the PLC
Also what about these modes of the SVG How to use these modes ?
Should the Data logger/Controller do both active and reactive power control, and we only send the calculated setpoint to the SVG to Produce a reactive Power or do we simply use one of the Modes it has
when the Grid send us a PF setpoint and also when Grid send us a Voltage setpoint how do we use the SVG and how the distribution happens
Please guide on the best way to use the Hardware and What will be the best way to distribute the reactive power
and how to effectively use the Modes
