Abstract


The face of the power industry trends, how to monitor the operation of large turbine generator performance, improve the economics of operating units to extend the operational life of the unit of China's power industry has become an important issue need to be solved . Unit power plant thermal efficiency is the basis for the overall economic benefits , economic benefits directly reflects the power plant is an important part of energy power plants . Thermal efficiency of the unit for real-time monitoring and analysis is to improve the power plant unit operation level effective method, but at the moment, many power plants are offline economic calculations , not only a waste of human and makes real-time calculation of lost . Run the unit for real-time monitoring and analysis just to make up for its shortcomings , is to improve the economic operation of the power plant unit effective methods. On -line monitoring of power plant unit operation for the understanding of plant operation and promptly adjust running, improved operating economy is very helpful . This boiler efficiency calculated using the \Turbine Relative Internal Efficiency calculated using thermodynamic method, which avoids seeking exhaust enthalpy , making the efficiency calculation is more accurate and requires less measuring point , the method is simple . The use of advanced computer technology to achieve thermal parameters for power plant unit , operation , equipment, soundness real-time monitoring and online analysis ; while simultaneously using computer technology to calculate the various economic indicators to monitor thermal unit operating status . Thus reducing the workload of the operating personnel to improve the economic operation of the unit .
