【Abstract】 It is a very important subject about how to measure the realtime parameters of different work points which reflect the dynamic characteristics for transition process of water turbine, to ameliorative regulation character better and to guarantee the equipment to run in dependable and economic way when the transition process occurs in the hydroelectric power station.How to solve the problems of realtime data acquisition is introduced by using the technique of VC++ 6.0 in the condition of windows. According to the characteristics of delivered small data block and large data capacity, the appropriate EPP parallel port and the dual port RAM DS1609 are chosen. As a result, it helps to improve the data acquisition and delivery with real time and accuracy and set a good foundation for the water turbine regulative system to carry out quickly accurate regulation.更多还原
