For the electrical coupling in of a three phase windmill generator (G) to the mains when the generator is driven at a speed close to the synchronous speed a single triac (Tr) is caused to initially build up the current in one or two phases in a gradual manner, whereafter the remaining two phases or one phase, respectively, are or is connected to the mains through simple contactor means (2), whereby the traditional fluctuation problems are counteracted in a simple and cheap manner. |
