I got in trouble with power synchronizing issue between the shore and vessle’s one.
The condition is this.
1. Operating the generator power in vessle with 440v 60hz 80kw.
2. About to sync it with shore power with 440v 60hz.
3. I speed down the generator under 60hz and also down the voltage a little bit of vessle.
4. The sync relay operate in good conditon. So the circuit breaker of shore power engaged smoothly.
5. Now i would transfer the load from vessle to shore, so down the speed generator in vessle.
6. But doesn’t transfer the power to shore. Not even a single killowatt.
7. It seems like parrallel inoperation but it doesn’t
8. Now i adjust the speed of generator, the indicator of frequency indicate downward. So, i think thet aren’t sync now.
what would be a problem?
Anyone who has some experiences like that, please share some knowhows….
i just think its problem could belongs to the power from shore and its device…
