Lose LP for winning the game
I lose Lp for winning a game. I lost power, so I disconnected. When I came back I played normally, but when my team won I lost my LP.

Usually, a loss of LP on a win is due to your MMR being much lower than your visible rank. You can correct this by improving your MMR by doing well in your Ranked Games (and winning of course!).
Glossed over "I disconnected", oops. Read below.
This is because leaver-buster flagged you for disconnecting for more than 5 minutes; therefore, you lose lp just like in a loss. Sucks, but the system has no way of recognizing that you reconnected and contributed to the win, so it will still count as a loss for you.
