A NEW TYPE OF ELECTRO HYDRAULIC DIGITAL SPEED GOVERNOR FOR HYDRAULIC TURBINES

摘要

The paper contains a short report on a four-year teamwork aiming to create a new type of electro hydraulic digital speed governor for hydraulic turbines. Computational methods, control software, design problems, and experimental validation are shortly presented. From an industrial point of view, the main idea of the new concept is the use of high-quality industrial electro hydraulic and electronic components only, in order to avoid manufacturing difficulties, high prices, and the manufacturer permanent technical assistance need. The actual performance of the prototype was found in good agreement with the theoretical prediction, and CEI demands.
