K-500-60/1500 turbine performance test results

On the basis of calculation-experimental technique the manouvring characteristics of the K-500-60/1500 turbine have been investigated. The tests are made at the Novovoroneh-5. Temperature distribution in the vessel and rotor of joint of high and medium pressure turbie steam pressure before control valves and flange heating of turbine external vessel have been studied. Test results confirmed the efficiency of the calculation-experimental technique of alternating regimes of wet-steam turbines. According to test results the optimization of starting regimes and algorithms of automated control over turbine operation start-up is made. High manoeuvring characteristics of the turbine, and a possibility of a start-u after shutdown for 54 in particular, are confirmed. In the case of start-up from the cold state the turbine can get the full loading in 2 h 10 min med. In the case of start-up from the cold state the turbine can get the full loading in 2 h
