Dears, we have 2X20MVA power transformers 66/33 KV WORKING IN PARALLEL TO FEED AN ELECTRIC ARC FURNACE (WORKING THROUGH INVERTER )AND ITS AUXILURIES&UTILITIES, THE TOTAL LOAD IS 35MVA, WHAT ARE THE RISKS AND POSSIBLE DANGEROUS INVOLVED IN CASE OF ONE OF THE TWO TRANSFORMERS FAIL, AND WHAT'S...

THANK YOU SO MUCH SCOTTYUK, (You might consider supporting local generation by operating in parallel with THE utility)THIS IS WHAT I PERSONALLY PRACTICED IN A PLANT THAT HAS 20MW STEAM TURBINE FOR LOCAL GENERATION WORKING IN PARALLEL WITH THE GRID, BY ADJUSTING THE LOAD SHARE CONTROL OF THE...

dears, I found this paper gives good ideas regarding the case we are discussing.https://files.engineering.com/getfile.aspx?folder=a1ab033c-4938-4e4c-9235-3a9537863469&file=2_36.pdf

what I understand from the answers: 1- most of the colleagues are not in favor of an isolated system of diesel generators. 2- am thinking about turbines, I mean isolated combined cycle power plant has 2.5 power capacity more than the EAF. 3-the turbines will be equipped with a highly responsive...

WE WILL BE HAVING IN OUR COMPANY AN ELECTRIC ARC FURNACE NEXT YEAR, IS IT POSSIBLE TO FEED THE SAID FURNACE BY DIESEL GENERATORS?

DEARS, DUE TO LACK OF ENOUGH WATER, I DECIDED TO GO WITH DRY COOLING INSTEAD OF WET COOLING FOR OUR COMBINED CYCLE CONDENSING STEAM TURBINE, FOR A SURPRISE I HAVE BEEN TOLD THAT I NEED TO MODIFY THE ROTOR VANES IN THE REAR SIDE OF THE TURBINE. IS THIS TRUE? IF YES THEN WHY?

am working as a power plant project manager, I prepared the project management organization chart I need some ideas on this.

dears, are there any other companies can do this job.

Dears, we are discussing the case of supplying power from a 230 MW combined cycle power station directly to a 100 MW electric arc furnace, the power station is connected to the utility grid, because utility put on me some restrictions to operate the furnace on the grid, I convinced the power...

dears, it is a 250MW combined cycle power plant, I meant to say what are your suggestions for the construction team organizational chart. thanks

thanks a lot, kindly could you please advice which a good reputable company that supplies this type of control?

why it is more difficult to connect a combined cycle power plant to loads than connecting it to the utility grid and what is the best way to connect the isolated power plant to the loads?

am building the team for power plant construction, grateful if can give ideas what positions are in this job?

Dears, I want to ask whether it's better to ship the transformer filled completely with oil or empty?

thanks a lot, Waross, its great you are on the forum thanks to everybody in the forum

Dears, I really need to do something, I have a problem with big compressor fails to start sometimes, I tend to go with Waross suggestion for open delta autotransforme . Dear Waross, could you please advise more information regarding your suggestion of installing two open delta 3phase...

Dear Waross, 1- voltage fluctuates between 373 to 378 volts 2- you have suggested installing two autotransformers in open Delta. grateful if you could explain to me why two transformers, not one. best regards

Dears, The problem is: compressor motor nameplate reads 400/415 volts while supply voltage at site is 380volts, what is the best selection for increasing the supply voltage from 380 to 400 volts AC, a 3 phase voltage stabilizer ( using servomotors ) or autotransformer, please consider that...

dears, appreciate your thoughts about the problem, compressors starting is DOL, no soft starters no autotransformeres , since the compressors rated voltage is 400v i believe we need to increase the supply voltage from 380v to 400-415v and apply compensating capacitors for each compressor to...

Dear Waross, I have taken the measurements and as I have a little experience with chillers compressors, do you agree that we add reactive power compensating capacitors to each compressor, it may help in in the issue of voltage drop. best...
