Application Study on the High Reliability of the Hydro-turbine Microcomputer-based Governor
高可靠性水轮机微机调速器应用研究

The problems of dual microcomputer-based governor in reliability are pointed out in this original. Moreover, reliability index is analyzed comparatively of the single, dual and triple microcomputer regulator. The dual microcomputer reliability is not further more changed, because of the unduly complex automatic switchover model. It is suggested that the major study of improving the microcomputer-based governor reliability trend to the simplified architecture and the optimized systematic function. Single microcomputer-based governor application study is the instance with the high reliability. The system function formulation, microcomputer core hardware selection, along with man-machine interface allocation are the main aspects to improve the microcomputer-based governor reliability. It has not only actual application value to numerous middle and small type governors, but also has the reference significance for the research to large type governors' reliability.
