The sliding-pressure operation is the main way of the huge turbine in the vary station, the paper analysis the economic influence of the cylinder efficiency; the unit's circle thermal efficiency; the feed water pump's efficiency in the sliding-pressure operation, and think about the influence of sliding-pressure operation parameters in different exhaust pressure; regulating valve opening and changes in the structure of the thermodynamic system. And then Based on the N330-17.75-540/540 steam turbine unit, the thermodynamic methods were firstly used to test the influence of the economics in different loads with different input pressures, we obtained the optimally sliding pressure curve in the variable condition, those were beneficial for the economical operation and on-line monitoring.
