On-line Monitoring And Analysis Of Energy Loss Of 100MW Coal-fired Power Unit In Haibowan Power Plant

Thesis is in accordance with unit(100MW)in the Haibowan power plant, and by way of the analysis of specific property to boiler and steam turbine, built the online monitoring mathematical model of economic nature of the unit. Through theory analyses, and reached the unified expression of specific internal work equation N and cycle heat absorption equation Q and they are two important references that involve in the thermal economic nature calculation of unit. According to design data and variable parameter calculation, puts forward the definite method for the target value of the chiefly working parameter in thermodynamic system , and analyzes the energy loss from on this foundation , reaching comparatively practicable model of energy loss analysis. On the foundation of mentioned above research use OO technology , and relies on the powerful function of Delphi 6 , and develops the on-line monitoring and analysis system of thermal economic nature for 1# unit in Haibowan power plant. This system can real-time monitor the various thermal economic indicator of unit and analyses the distribution of energy loss and it has a positively effect to guiding the operation of the unit in the optimum condition.
