Abstract: India is on the threshold of being a world leader in steel production. In this context, India being the 4th largest producer of steel in the world is in a position to dominate the steel industry. This beng the case, Inida should concentrate more on innovate solutions to improve its steelmaking. However, there are a lot of challenges to be faced regarding production of quality steel in accordance with International norms. In this paper, some of the challenges are discussed and innovative solutions are given. Recent research on steelmaking has been given and progress in Indian steel making has been shown graphically Various types of steelmaking have been briefly touched upon and the challenges that India is facing have been outlined. India has to take up these challenges and is poised to be a world leader in steelmaking. Therefore, improvements and innovations become necessary and, innovative solutions are required in steel making in order to face the challenges of the future. This paper discusses these challenges from an Indian perspective. Data are given from literature indicating some of the innovations already made and some more innovative methods which are unique to the Indian situation are discussed. These ideas when implemented could result in higher and cleaner steel productivity. Future trends in steelmaking have also been suggested. It is hoped that the new ideas given in this work will benefit and the global steel industry in general and. Indian steel industry, in particular.

Abstract: This paper provides a perspective on protective system at 22kV overhead feeders in Gaza distribution network using symmetrical components method and ETAP software. Electrical disturbances from high rate of outage feeders at the 22 kV overhead power lines frequently cause disruptions on the generating plant and customer loads. One sub-transmission feeder from a parallel set of ten 22 KV feeders (140 MW) in the Gaza west substation is selected as a case study in this research. Because the protection system lacks a data fault recorder (DFR), the paper calculates the fault currents at both the nearest substation bus and the last bus in the distributed feeder using the symmetrical components method and verifies the results by using ETAP software simulation. The results from calculating the minimum fault at the last bus indicated that the current protective parameters are reasonable and satisfied for detecting and interrupting the occurring faults. This author paper proposes increasing the fault clearing time at farthest feeder bus to make protective functions less sensitive by adjusting TMS to 0.08 for time overcurrent and earth fault and setting pickup level to 3.8 for instantaneously overcurrent. The design model is run on the selected feeder, and simulation results guarantee the proposed model's accurate performance for both overcurrent and earth faults after changing the fault clearing time. There will be no miscoordination of protective devices or operational risks while running the design model for the selected feeder with new settings. Gaza's distribution feeder network requires structural improvements to become more reliable and to reduce the high rate of feeder trip, and practical recommendations to improve current installation distribution grid are included in this paper.
