Target value surface and coal consumption growth surface in steam turbine unit performance monitoring systems

In order to optimize the performance of the steam turbine unit performance monitoring system to improve its reliability,stability,and precision,the target value surface and the coal consumption growth surface for performance monitoring under varying working conditions were constructed.The imported-type 600 MW supercritical steam turbine unit was used to illuminate the design concept,mathematical model,and construction process of the two kinds of surfaces.
