Parameter is different, for example data of being struck by lightning are needed in the emulation of lightning fault, but in the emulation of non-lightning fault, then not
Have lightning parameter), the required form of ATP Simulation Calculation master files is converted into, since ATP wants model file form
Ask very stringent, the character length that different type component data takes is different, and the arrangement requirement to character is very stringent, therefore
Need to carry out data format processing, change into the character of certain length.When data length is long, it is necessary to switch to scientific notation
Form, and the form for changing into character string preserves.When data length is inadequate, it is necessary in above blank fill, and change into character string
Form.For example the length of the parameter of force device is mostly six characters, it is therefore desirable to the parameter in Microsoft Excel is read,
And the length of six characters is changed into, if inadequate six of the data in Microsoft Excel, need above supplementing space, such as
Fruit then needs to change into the form of scientific notation more than six, then when generating ATP codes, directly exports the character of six
The data of form.Such as：In ATP, the length of power data is generally 10, if initial data is ' 123456789 ',
