cogeneration plants
(OP)
There are some questions of cogeneration power plants i need to ask you..
1- How is the feederthat feeds excess energy to or draws energy from the utility named ?
2- İs there an important locking of circuit breakers on this feeder (I heard but dont know if there is one why?)
3-İs it important where the connection is made to the utility? distribution or transmission system makes difference??

RE: cogeneration plants
The seniors involved with this project would be able to answer your question more satisfactorily than any strangers on this forum.
It would be more productive if you work along with your senior engineers and gain some experience for a few years and brush up on you basics and then come to forums like this to ask basic questions.

1. Follow the rules of your utility.
2. I don't know what you mean by locking. Do you mean interlocking?
3. Yes.
RE: cogeneration plants
also i want to learn the technical name of this feeder, for example in my country it is called as "autoproducer feeder"
RE: cogeneration plants
A feeder is a feeder is a feeder in this country. Is there a more techincal name?

2. Do you mean electrical protection? You must protection relays that disconnect the generator in the event of problems. This is a whole engineering topic to itself.
3. Yes. It depends on lots of things such as generator size, existing utility configuration and cost.

RE: cogeneration plants
A co-gen project may be 150 kW connecting to a 240V service or it might be a 1200 MW co-gen connecting to a 500 kV substation.
Some plants connect to transmission lines, some to distribution feeders and some just connect inside the owner's power system.
It depends on the local utility regulations and the laws and customs of the country.
All I design is co-gen plants. In 25 years in the business I do not recall a specific name for the plant interconnection feeder. If the engineering custom or practice in your area has a special name for types of connections, you will have to research the definitions.
So the answer to your comments is it depends on the plant size, location, interconnecting utility, voltage, regulations, local engineering practices and other factors.
