Stuty of steam turbine system based on wetness measurement

Wang Hongyun (Missile Engineering Department,Ordnance Engineering College,Shijiazhuang 050003)  
The existence of wetness in steam turbine has badly effect steam turbine to run in economically,security and reliably.For measuring the wetness of steam in a turbine perfectly,the control system that used MSP430 as the processing core is designed,including the automatic frequency tracing system and equal precision measurement system.The automatic frequency tracing system can track the resonant frequency well and get to 2.44 kHz,while the equal precision measurement system,it's resolution ratio can get to 10-7 at the frequency of 10 MHz.Through the simulation,these two designed parts can made the accuracy of wetness get to 0.4% or even small,proved the feasibility of the programmer and satisfied the requirement of wetness measurement system.
