Abstract
This is a four-part paper series, which elaborates the novel hybrid
design where the rated capacity of 415 kW solar power plant producing
guaranteed 1.66 MWh per day, owned by a private firm supplies electrical
energy to its privately served consumers and also feeds 25 kV railway
distribution feeder located 20 Km away from the premises. This 415V
transmission is boosted and feeds the lagging feeding post of 40 km long
traction line which has hybrid 132 kV/25 kV transmission from DISCOM or
Govt. owned substation, supporting train speed upto 160km/hr. These four
part paper series are complete guide, enough to motivate investors and
successfully demonstrates relay trip coordination, leading the role of
one section of feeding post from 132 kV/25kV utility and handling of
other safety and fault conditions. In this Part-1, the solar plant
design with anti-islanding, guaranteed uninterrupted power supply,
typical railway distribution feeder, design of proposed feeder - its
connection to feeder, mounting pole, booster transformer, circuit
breakers, isolators, lightening arresters, has been explained. The whole
proposal is also simulated and the results are in the dataset. 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.
