Target Value Surface and Energy Loss Surface in the Steam Turbine Unit Performance Monitoring System

In order to optimize the performance of the steam turbine unit performance monitoring system, improve the reliability, stability and accuracy of the system, a new idea to establish target value surface and coal consumption growth surface in different load is presented. Take an imported supercritical steam turbine unit, which capacity is 600 MW, as an example to expound the design idea, the mathematic model and the construction process of these two types of surfaces.
