Article Preview

In order to eliminate the disadvantages of the traditional electro-hydraulic converters in the turbine governor, a new electro-hydraulic converter with strong restoring-motion was studied in this paper. The basic structure and working principal were analyzed, and the basic characteristics were described in detail. The simulation analysis of its dynamic characteristics was made by using Simulink software and the methods for improvement of the performances were suggested. The results of field tests indicated that the performance indexes of the hydro-turbine governors with this new technology were conformable to or higher than GB. It is concluded that the new electro-hydraulic converter has a promising future in engineering applications, especially in turbine governing systems that suffer from jam fault.
