Here's a list. But mostly of nominations...

Yes, SPN has won a couple awards. Not really big ones though, but it's been nominated two times for an Emmy for sound editing. It also won the people's choise award for best sci-fi/fantasy toon this year(Go SPN!) and it's been nominated for a lot of awards, especially sound editing too. tinzn92 zei there's a lijst of it link on IMDB.

Unfortunately most big award like the emmys don't nominate shows like SPN a lot for bigger awards like best supporting acotor of something, which imo Misha Collins so deserved!
