Inverter Quattro 15Kv issue connecting with Zordan LMDE 150 PM0 150 KVA generator

f8369b0177f1_inst_ttyO1_Interfaces_Mk2_Tunnel.zipHi all

I manage a large solar power system running in a hospital in Africa. I wanted to connect a 150 KV Zordan generator to this system provided by 3 inverters quattro 15KV.

The generator is only a year and a half old and has recently been revised. The current and frequency are stable, but the inverters are unable to synchronize it (drop down every few seconds).

Anyone have a suggestion?

I have already tried many of the recommendations found in this forum unfortunately without success.

Hi @Arty

Can you measure the frequency generated by the generator?

Hi Daniël, many thanks for the quick answer!

the generator display is showing around 52,4 Hz without load then it drops to 49.5 Hz with load, seems to be quite stable…

But I ask to do some measurements directly on the phases using an instrument to check if display showing correct and come back to you soon ...

Hi @Arty

That is a -very- unstable frequency, and probably the reason the inverters cannot accept it.

I'd ask the company that revised the generator to fix the generator so it produces a much more stable frequency.

Hi Daniël,

finally, I could bring working the generator, however I put the input current limit at 40 Amps and a put a check marks to dynamic current limiter.

My question is the following since the generator is able to produce over 120 Amp, can I increase the current limit at least to 75 Amps and keep the check marks to dynamic current limiter ?

Thnaks a lot

You could try that.
