13.8kv , 50MW distribution
13.8kv , 50MW distribution
(OP)
a 50MW gen at 13.8kv will be located 1.5 km away from the load.
I was wondering if anyone has any experience running U/G and tray rated cables for that long distance. 50MW is a lot of current, about 2700A. The cables we could think are using 1000MCM single conductor aliminum. If we use these, we might need 15 or 18 cables burried in a duct. (the design will have partial burried and parting cable in the tray)
I would appreciate if anyone can recommend a better solution to minimize cable runs. We do not want to run O/H lines. Response appreciated. Thanks

RE: 13.8kv , 50MW distribution
You really, really, really need a transformer between that generator and the load, so step the output up to 34.5kV or 69kV and back down to 13.8kV at the load. You could also go to 1500kcmil or even 2000kcmil copper conductors and reduce the number of conductors. Overhead will obviously let you use much smaller conductors.

But, 13.8kV, 50MW to 1.5km not so good solution too.
Are you have load 13.8kV on the second end or only connection to grid?

Is not simple decision.
You need a serious technical and financal evaluation and check a local grid options for connection.
For exapmle:
install step-up transformet in power palnt yard with two 220kV field or may be only one field and connect this field directly to 220kV line without additional bay, that menas T-connection and your trafo will be protected by line zone protection.
