Is there any use of enabling Power swing blocking in a distance relay on radial connected line (of 30 km long) to Hydro generator of 50 to 80 MW capacity?
 
Yes, depending on the system. I assume you're specifically referring to the relays looking into the hydro from the remote end - this would be similar to a distance relay at the generation site, looking into the GSU (with a little extra impedance). I've seen similar sized units used for black start - is this such a site?
