Abstract
This is the second part of two-part series where the novel hybrid design
of 1.5 MVA 25kV traction powered by 415 kW solar grid, capable of fully
supporting the entire load of the section of the Govt./DISCOM railway
feeder has been presented. In this second Part-II, the per-unit system,
zero sequence network diagram, controller design, fault calculations
(L-L, L-G), idmt relay settings, safety measures and guaranteed scheme
of relay trip coordination with 1.5 MVA 132kV/25kV State utility owned
feeder and proposed 1.5 MVA 25kV feeder has been explained. The whole
proposal is also simulated and the results are in the dataset. railway
distribution feeder along with various compensators is explained. The
whole proposal I have left r&d, so will not correct update or complete
papers. The earlier version of two parts, which was able to get saved
from computer crash is uploaded.
