Test of Optimization of Sliding Pressure Operation and Analysis of Sliding Pressure Operation with Partial Valves Open

In order to study the optimization of sliding pressure operation mode,increase the efficiency of generation units at low load operation and meet the demand of peak load regulation for power grid,tests were made to verify the economy of sliding pressure operation modes for several units.The test methodology,items and procedures are summarized.It indicates that the sliding pressure operation with partial valves open could greatly reduce the throttle loss,and increase the economic benefit.It has made useful trial for the energy saving and consumption reducing of the generation units.
