Hi all,
I'm looking to upgrade the power gen on out oil processing facilities.
The obvious choice is gas engine but I need to also be able to operate on diesel in the event that the fuel gas system fails.
So I'm in the market for 4 x 2.5MW; 400V; 50Hz gas/diesel reciprocating machines.
To date...
I have a number of ESP drive trains that are powered from island generation at 400V;50Hz through a 450kVA VFD and a 525kVA step-up transformer to 2600V then down hole cables of varying lengths from 1000m to 2600m to a 225kW pump motor. The VFD has an output filter. The VFD operates as a 6 pulse...
I have a 226kW heater that's controlled through a 12 pulse thyristor unit.
This has caused system instability on our small network causing the main power generator (Gas Cat with Woodward Electronic Governor) to hunt.
Changed the control card in the thyristor unit to proportional control...
