| With the analysis of the 300 MW units operating conditions, a new optimal administrating method was carried out and the proposal about how to realize it is also presented in this paper. At first the optimally operating experimental data of a typical 300MW unit is analyzed and the three stepping experiments to gain the best running parameters is described. Then the calculating model is established to develop the Optimal Performance Administration System Of Unit and this system s interface is programmed. At last the suggestion about how to apply this system and where it could be made perfect is given. |
