Relay Setting calculation engine is a industrial standard software to compute the relay settings for the over current, distance, unit protection relays (transformer differential, bus bar differential, line pilot, cable differential, restricted earth fault relay etc…).
Here the complete power system network is considered for arriving at co-ordinated settings for the graded relays. There is an interface between this engine and protection database management for exchange of necessary settings. This also includes other supporting analysis modules like load flow analysis, short circuit study, relay co-ordination, transient stability, electromagnetic transient analysis etc…
Protection suite addresses some of the typical issues faced by the protection system community which is managing various different types of relays. Due to the increase in functionality of the relays and also huge settings data, it is very difficult to maintain the settings in conventional ways (hard copy, files etc…).
And also the old ways of storing the data lacks in tracking the change history of the settings and templates, also the settings has to be done and then updated in the files. With this approach the linking of the protection calculation, storing of different relay manufacturer templates and relay setting, tracking of the changes (template and setting life cycle management) can be achieved.
The utility or the industry with this kind of Protection management system can have the following advantages :
- Accountability of settings (track changes, ownership of the process).
- Save time (in accessing the relevant data).
- Central repository of protection settings.
