Platform provides parameter editting function for all kinds of power equipments, allows users to self-setting relevant parameter；
2) short trouble calculates:
The data platform is configured with a variety of short trouble models using short trouble computing module, and user chooses fault type
Afterwards, corresponding computation model is called to complete calculation of fault automatically；
3) relaying configuration:
The data platform relaying configuration module is that power equipment is configured with a variety of protective relaying devices, and user is as the case may be
Choose protective relaying device and adjusting project；
4) adaptive setting:
The data platform is that protective relaying device is configured with adaptive setting template using adaptive setting module, and user is according to specific
Situation independently selects adjusting project, using feature identification method Auto-matching adaptive setting template, the ginseng configured according to template
Number information and calculation of fault result are automatically performed adaptive setting；
5) definite value is checked:
The data platform is checked module using definite value and is checked online to adaptive setting result, to the definite value for being unsatisfactory for requiring
It is adjusted until meeting the requirements；
6) setting value management:
The data platform is that all kinds of protective relaying devices are configured with general fixed value list template, root using setting value management module
According to protective relaying device automatically retrieval and match protection definite value, by fixed value information from top to bottom, be automatically filled in template from left to right,
Form fixed value list.
