| Abstract: | It is proposed that the LM algorithm based on Givens orthogonal transform should be adopted for state estimation and checking for steam turbines. The LM algorithm was applied to a 300 MW reheat condensing steam turbine, and results show that the LM algorithm based on Givens orthogonal transform is effective when large measurement errors and redundancy exist. |
