Abstract: Taking the generator set of Hunan Valin Lianyuan Iron and Steel Company Limited as an example, an accident of generator stator winding overburning, which is caused by that the generator outlet switch switched on in delay time, the generator had been connected into the grid asynchronously. The reasons of the accident were analyzed, and the targeted treatment method was given, which provides reference for handling similar problems.

Key words: generator, asynchronous connection into grid, switch delayed switching on, accident of winding overburning, countermeasure
