| Abstract: | It often arises in the unit B15-90/39 for Bengang power plant that the shaft vibration exceeds the limit norm, and the switch trips during starting. By testing and analyzing the frequency spectrum, we adjust the rotational speed of the turbine to avoid it runs near the limit speed. As a result, the unit runs safely. |
