| Abstract: | The jam fault of the differentiator is dangerous to steam turbine. In this paper, the reasons of the jam fault of the differentiator are examined, including jam of main valve, jam of the delay valve, and jam of the relay valve. The simulation model of the jam fault of the differentiator is given. And the simulation results of the different types of jam are also presented in this paper with the model. It also has been proposedto diagnostic jam fault with Force-Balance-residual method. The results in this paper have also been examined by the exact data. |
