Abstract
The dynamic behavior of a directly combined binary turbine system is investigated experimentally and theoretically in this work. In the theoretical investigation, the dynamic behavior of the system is discussed from the viewpoint of the network theory. In this case, the components 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 derived. The validity of the model is proven by comparison with the experimental results, which are the frequency responses examined with respect to the generator load changes. In addition, it is shown that the present model is very effective in predicting the dynamic behavior and the mechanism of power generation in the directly combined binary turbine systems.
