Abstract: Aiming at the problems that handdrawing thermal equilibrium diagram for turbines is timeconsuming, unfixed graphics formats and poor commonality, the dynamic drawing of industrial steam turbine thermal equilibrium diagram was developed. First of all, the standardized legend libraries were established, including components legends, line legends and text legends. Secondly, procedures were programmed in Visual Studio 2005.Last but not least, the dynamic drawing of industrial steam turbine thermal equilibrium diagram based on AutoCAD application was achieved. The results indicate that the dynamic drawing system can seamlessly integrate with thermal design software, and draw thermal equilibrium diagram of different conditions or different units. The manipulation is simple, efficient, and drawing specific, so it is a very good development tool to improve efficiency for designers.
