Prediction Method of the Load Regulation Range of C330/262 Type Cogeneration Steam Turbine

With the increasing of electric power system peak-valley gap and the capacity of cogeneration unit,there are some difficulty for the stability and dispatching of the power system. The ability of peak load regulation of cogeneration unit is influenced due to the limitation of heating load. In this paper the load regulation range prediction method of cogeneration steam turbine is given,which is suitable for different conditions under the different heating load. Taking C330 /262-16. 7 /0. 49 /538 /538 type steam turbine as an example,the electricity load is predicted. The prediction method proposed in this paper has certain guiding significance for peak load regulation of cogeneration unit.
