Study on the influence of boundary parameter variation on the optimization of steam turbine valve point sliding pressure in a thermal power plant
In order to further study the influence of boundary parameter changes on the sliding pressure optimization of steam turbine distribution point in thermal power plant,the mathematical model of boundary parameter changes is studied and obtained by using an online calculation optimization method.The optimal sliding pressure is calculated by using the pressure difference corrected by the change of each boundary parameter,and then the optimal sliding pressure is obtained by calculating the optimal sliding pressure difference,the design value of sliding pressure and the limited conditions.In order to optimize the sliding pressure and realize the quantification and visualization of the sliding pressure in all seasons,it can guide the actual operation of the unit and effectively improve the economy of the unit.
