Having reviewed the research state of mid-and long-term risk dispatching of hydropower station,this paper describes the uniform-different-contrary characteristics of flow,generation water and power price, and presents a model of mid-and long-term risk dispatching based on set-pair analysis.

On the base of brief introduction of the basic theory of multiple regression,this article gives the multiple estimation regression equation applied to predict the apoplexy risk and tests the equation s validity by the test of regression model′s hypothesizes、significance of regression relationship and the goodness of fit.
