DEAR friends I am new to this forum.
We, are operating a big fertilizer complex comprising Ammonia plant Urea and Di ammonium Phosphate. Our Ammonia is an old plant, design for 60hz power, purchased and relocated from USA. We have no other option to operate our plant on 60hz. Any effort to convert it on 50hz needed major design modifications. We have our own generation, powered by two GE frame 5 gas turbines approximately 23MW each, 13.8kv, 60hz ( American system). Complex total load is around 22 TO 23 MW. BOTH TURBINES RUNS IN PARALLEL AND SHARE 50 -50 LOAD. Two Gas Turbines (GT) are operated in Combine Cycle mode with HRSG. With One GT in "Droop" mode one in " Isochroous" mode controlled by GE Mark 5.
We are planning to sell our surplus 45% power (60hz) to utility grid at 50hz. For connecting 50 c/s utility grid we have to sought a solution which is most reliable and least disturbing to our system and productivity. As the grid to which we are planning to connect is far much bigger then our system approximately 2000MW or even bigger.
Power we trying to put on 50hz grid is approximately 15 to 20 MW. With the following details; GENERATION VOLTS: 13.8KV. 60HZ, 3 phase GRID SIDE CONNECTIVITY OPTIONS: 132KV OR 11KV AT 50HZ. We need your help to sought most feasible and economical solution in this regards.
Please clarify the following:
1) What could be the possible ways or technical means to synchronized two different systems.
2) What type of Frequency Converter you can offer and would be most suitable choice in our case.
3) Static or Rotary ? which design could be most suitable choice.
4) What type of stability issue may encounter if two system are connected through Frequency converter (static or rotary).
5) Or any other convenient reliable solution for this scenario Hoping the early response from your side.
Best regards,
