| titleOfInvention | Method for online monitoring performance of steam turbine of coal-firing unit |
| abstract | The invention provides a method for online monitoring performance of a steam turbine of a coal-firing unit. The method includes the following steps: step 1, according to boiler operation designing procedures, acquiring boiler structure parameters, and reading real-time data of operation condition measuring points of a steam-water system and a heat exchanger system at a given moment from a real-time database of a DCS (distributed control system); step 2, calculating specific enthalpy and density of a working medium on the basis of a working medium physical parameter library; step 3, according to a working medium side energy balance model, respectively calculating heat absorbed by the working medium in the steam-water system and the heat exchanger system to acquire total energy increment of the working medium; step 4, building a transmission function model between the total energy increment of the working medium and output power of the unit, and acquiring efficiency and heat consumption rate of the steam turbine through parameter recognition. The method can be used for online monitoring operation conditions of the steam turbine and providing technical support for coordination and optimization of the unit. |
