2. OBJECTIVE :
To develop and implement an innovative
digital version of the existing conventional
model of analog synchronizing relay, thereby
upgrading the existing design, ensuring
effective and reliable operation with the
compact model at very low design cost.
17. Advancements of the proposed model :
1. The proposed model is a compact digital model.
2. The model also replaces the bulkier trolleys with
enhanced operation as it is interfaced with real time
monitoring and control.
3. More simpler, effective and reliable synchronization is
ensured at very low design cost.
4. Best suited for synchronization at multiple voltage levels
5. Depending on the healthiness of the system, it can be
operated in manual or automatic mode.
6. Response time of the relay is less then 20ms, which
makes it more efficient compared to the analog ones.
18. Project testing :
This project was tested and verified in a real
time practical environment, by connecting the model
to the bus bar protection panel of a 230 KV feeder at
400/230-110 KV substation at Alamathy, Chennai .
It is worthy to be noted that the model was
demonstrated in the presence of all Engineers of
Alamathy substation and 230KV Korattur substation
and was certified to be a quality relay.
19. End note :
As per our objective, the proposed
compact digital model has been proved to
offer more enhanced operation as it is
interfaced with real time monitoring, thereby
ensuring simpler, effective and reliable
synchronization at very low design cost.
We thank all our College faculties ,
mentors and field Engineers for guiding and
motivating us throughout the course of
project work .
