| Abstract: | From the perspective of generating the speed protection curve,this paper studied on the main method of over-speed protection.Based on ATP speed protection model,this paper calculated and analyzed the result of the safe braking curve when it selected different steps,compared with the accuracy of the braking curve on the different step cases,selected the method of combining the time step with distance step,used piecewise iterative method to calculate the speed protection curve.Finally,the paper implemented ATP protection curve simulation through the Visual C ＋＋ 6.0 development platform. |
