Accurate short-term wind power forecasting has important significance to safety, stability and economy of power system dispatching and also it is a difficult problem in practical engineering application. In this paper, by use of the data of numerical weather forecast, such as wind speed, wind direction, temperature, relative humidity and pressure of atmosphere, a short-term wind power forecasting system based on BP neural network has been developed. For verifying the feasibility of the system, some experiments have been were carried out. The results show that the system is capable of predicting accurately the wind power of future 24 hours and the forecasting accuracy of 85.6% is obtained. The work of this paper has important engineering directive significance to the similar wind power forecasting system. © (2013) Trans Tech Publications, Switzerland. Source

The flow characteristics of eight rectangular microchannels with different geometric parameters are measured when distilled water is used as a working fluid. The relationship between friction factor or Poisuille number and Reynolds number is obtained, further the influences of hydraulic diameter, the ratio of height to width, and the ratio of channel length to hydraulic diameter on flow characteristics are analysed. The results show that the friction factor and Poisuille number increase with the decreasing hydraulic diameter and length-to-hydraulic diameter ratio at the same height-to-width ratio. For the microchannels with nearly the same length-to-hydraulic diameter ratio but different height-to-width ratio, the friction factor and Poisuille number grow with the reducing height-to-width ratio. Specially, in the range of variation of parameters interested in our study, the influence of height-to-width ratio is more denominated than the other geometric parameters. Hence the friction factor of rectangular microchannels is a complicated function of hydraulic diameter, height-to-width ratio and length-to-hydraulic diameter ratio. ©, 2015, Editorial Department of Journal of Drainage and Irrigation Machinery Engineering.
