DYNAMIC CHARACTERISTICS AND MODELING OF A DIRECTLY COMBINED BINARY TURBINE SYSTEM CONSISTING OF A 40 KW STEAM AND A 30 KW R-11 TURBINE

The dynamic behavior of a directly combined binary turbine system is i nvestigated experimentally and theoretically in this work. In the theo retical investigation, the dynamic behavior of the system is discussed from the viewpoint of the network theory. In this case, the component s of the system are represented as two- or three- port elements of the network and the vapor flow rate and shaft torque are appropriated for the through variable, and the vapor pressure and rotational speed for the across variable. As a result, a very simple network model is deri ved. The validity of the model is proven by comparison with the experi mental results, which are the frequency responses examined with respec t to the generator load changes. In addition, it is shown that the pre sent model is very effective in predicting the dynamic behavior and th e mechanism of power generation in the directly combined binary turbin e systems.
