Introduction
Protection suite is comprehensive enterprise solution packaged essential components required to operate a robust power system. It includes, a sophisticated manufacturer independent protection equipment modeling framework, life-cycle log and tracing mechanism for the protection template and settings, industry standard settings calculation support integrated with analysis tools.
A web based protection management suite provides the solution to overcome few of the major difficulties in the conventional protection settings management life cycle.
MiP-PDMS is a web-based, enterprise-level solution designed to help utilities and industries manage protection relay settings through a workflow-based change management system. It also keeps track of all changes made to relay settings through audit logs, helping streamline the audit process.
The Management Information System (MIS) allows utilities and industries to generate detailed statistics on relays and their settings, and allows easy comparison of settings across relays in the network.
- Create, store, and manage relay settings—regardless of the manufacturer.
- Full tracking of all changes made to relay settings.
- Built-in workflows to initiate and implement relay setting changes.
- Seamless integration with the Relay Setting Calculation Tool (PSCT):
- Download settings from MiP-PDMS to PSCT for protection simulations.
- Export simulated settings back to MiP-PDMS for review and approval.
- MIS reports to support daily operational decisions.
- Customizable modules for tripping incident logs and protection audits.
- Southern Regional Power Committee.
- Eastern Region Power Committee.
- North-Eastern Region Power Committee.

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.
BENEFITS OF PROTECTION SUITE
- Ensures responsibility and ownership of changes done in the relay setting parameters among the process owners.
- Assists the Protection engineer to conduct the required studies to arrive at adequate settings and verify the settings through simulation.
- Enables complete tracking of the relay settings changes.
- Supports the planning engineers in planning the protection system to better adapt to a system-wide disturbance.
- Facilitates the protection engineer to access the details of all the equipment in the network, and in conducting periodic fault studies followed by relay setting, verification and co-ordination studies.
- Provides the scope for addressing any instability in a hierarchical manner.
- Customized reports and MIS can be generated as per the requirement.
- Facilitates for Post- mortem analysis of faults.
