Research And Design Of Double Adjustable Hydro-generating Optimal Association League Test System

The turbine energy index more and more aroused people's attention, in this the testing and testing methods of energy index, is generally concerned by designation, manufacture, operation and other units. The current test means is difficult to meet with the need of league test, according to this, This topic make the research and design for double adjustable hydro-generating optimal association league test system.This paper analyzes the domestic and foreign research and development in the hydropower automation devices, according to the situation of the domestic large and medium-sized hydropower basically haven't comparatively perfect hydro-generating operation of the optimal association league detection device, this paper proposes a new design that can accurately test double adjustable accurately measuring unit of the optimal association league characteristic equipment to train. This system can be applied to various type, able to simultaneously once or association league test, basically realized covariance league parameters measurement of the unit together, then the data collection through the communication interface upload PC, realization of the data gathering graphical processing.At hardware, based on dsPIC30F6011 realized data acquisition, processing, display, communication and keyboard, and other functions, and in processing power signal chose add window interpolation Fourier transform to analyze and resolve to produce the direct choose FFT the leak, aliasing problems. At software, write dsPIC30F main program and each function module procedures, and the son of programming window interpolation FFT used the C language and assembly language combination way to improve code enforceable. In the PC software writing on using VB (Visual Basic) language to compile and access database programs, basically realized constant detection, parameter setting and data analysis function, friendly interface, intuitive, and has certain applicability.Use the relative method to calculate optimal association league experiment, obtains the relevant data and curve, demonstrating the sophistication and effectiveness of the test system.
