(6) Matlab completes the emulation of all failure scenarios under each fault parameter variation combination by nested circulation.
In described step (3), the variation of every layer of nested corresponding parameter, variation range is to initial value, final value that should setting parameter, and circulation step-length is to step-length that should setting parameter; To nested not requirement of inside and outside order;
The concrete grammar of described step (4) is: innermost loop, Matlab switches current path to the atpmingw path under ATP installation directory, in * .atp file corresponding to realistic model, in written document mode, the new value of each fault parameter is write to each self-corresponding position; Matlab calls executable program Tpbig.exe, carries out the emulation to amended * .atp file, and after emulation finishes, Matlab calls executable program Pl42mat.exe, and the * .pl4 file that emulation is generated is converted into the * .mat file of the same name with * .atp file.
In described step (5), its concrete grammar is: Matlab reads failure message corresponding to end-around carry now, and is integrated into character string; * .mat file is imported in its work space Workspace, and with this character string, to the rename of * .mat file, Matlab receives the data storage location of the setting in gui interface, and the * .mat file after rename is imported to this position.
The concrete grammar of described step (6) is: for whole nested circulation corresponding to all parameters, circulate and successively enter interior loop by skin, after interior loop stops, then carry out outer, entered in interior loop by skin circulation again, in the time that outermost loop is complete, all emulation completes.
Beneficial effect of the present invention is: can make Matlab organically blend in the authority aspect power system transient simulation in the advantage aspect programming, computing, data processing, graphics process and ATP, and then can utilize the complete mathematical model of ATP to carry out flexibly, efficiently electric system simulation calculating, study multiple parameter and change the impact on system, with emulation degree of accuracy of other simulation softwares of accuracy verification of ATP etc.; Possess higher using value and open application prospect.

Embodiment:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, a kind of traditional call method that utilizes ATP emulation is revised parameter in ATPDraw interface, manually start ATP emulation, carry out P142mat.exe file, simulation result is converted into .mat file, manually Matlab is imported to .mat file, carry out data analysis; Circulation N time, in traditional method, each simulation process all needs artificial participation, emulation enormous amount, N can reach at 103 o'clock, complex operation, time, manpower expend huge, and efficiency and operation accuracy rate are lower.
As shown in Fig. 2-Fig. 4, a kind of realization flow of Matlab-ATP integrated automation call method is:
1) under the work path of Matlab from ATP installation directory, derive the * .atp file for the treatment of realistic model, this file is imported under atpmingw path.
2) Matlab receives the variation range of each fault parameter of inputting in gui interface.Become multilayer circulation nested the change process of multiple parameters, the variation range of every layer of nested corresponding parameter; Step 3), 4) all for innermost loop.
3), in innermost loop, Matlab switches current path to the atpmingw path under ATP installation directory, in * .atp file corresponding to realistic model, in written document mode, the new value of each fault parameter is write to each self-corresponding position.Matlab calls executable program Tpbig.exe, carries out the emulation to amended * .atp file.After emulation finishes, Matlab calls executable program Pl42mat.exe, and the * .pl4 file that emulation is generated is converted into the * .mat file of the same name with * .atp file.
4) Matlab reads failure message corresponding to end-around carry now, and is integrated into character string; * .mat file is imported in its work space Workspace, with this character string to the rename of * .mat file.Matlab receives the data storage location of the setting in gui interface, and the * .mat file after rename is imported to this position.
