On the basis of investigating present development of computer software about protective Relay Setting Calculation, the author summarized the short coming: the generalization of software is unsatisfactory, the users can't maintain the system easily, and the setting calculation is not connected with the sensitivity calculation to make the setting more reliable. In order to improve the universality and practicability of software, we should develop visual protection setting tuning software, which is based on visual fault analysis software and can combine users' experience to get the result quickly and directly. |
