Research on Dispatch Method of Optimizing Heat Unit Load

According to the fundamental characteristic of heat supply unit,the mathematical model of determining pow er generation by heat is established on the basis of steam turbine various conditions. On the basis of on-line monitor of ordering pow er generation by heat for heat unit,the methods of load dispatch for maximum and minimum load and adjusting the load rapidly are discussed for heat unit and the method of load dispatch in the model of energy conservation is also discussed. The issues including the option of optimizing dispatch models and heating capacity and the limit of supply and return w ater temperature are all analyzed in the course of load dispatch. The method of forecasting electric pow er and electric energy is put forw ard on the basis of w eather parameters. It is proved by practical application that the dispatch of optimizing heat unit load offers a technical support for pow er grid dispatch decision-making.
