Cost-Benefit Analysis of Two-Non Identical Cold Standby System Subject To Non-Availability of Water Resulting Failure to Produce Hydroelectric Power and Failure Due To High Acoustics

Abstract

India was the 7th largest producer of hydroelectric power in 2008 after Norway: 114 TWh and 3.5% the world total in 2008.The potential for hydroelectric power in India is one of the greatest in the world. India is endowed with economically exploitable and viable hydro potential assessed to be about 84,000 MW at 60% load factor. In addition, 6,780 MW in terms of installed capacity from Small, Mini, and Micro Hydel schemes have been assessed. Also, 56 sites for pumped storage schemes with an aggregate installed capacity of 94,000 MW have been identified. It is the most widely used form of renewable energy. India is blessed with immense amount of hydro-electric potential and ranks 5th in terms of exploitable hydro-potential on global scenario. The present installed capacity is approximately 39,788.40 MW which is 17.39% of total electricity generation in India. The public sector has a predominant share of 97% in this sector. Water plays an important and pivotal role in producing hydroelectric power. Non-availability of water results failure to produce hydroelectric power. Reliability is a measure of how well a system performs or meets its design requirements. It is hence the prime concern of all scientists and engineers engaged in developing such a system.. In this paper we have taken two types of failures (1) FNAWnon- availability of water resulting failure to produce Hydroelectric Power (2) FHA-failure due to High acoustics When the main unit fails due to High Acoustics then cold standby system becomes operative . High acoustics cannot occur simultaneously in both the units and after failure the unit undergoes very costly repair facility immediately. Applying the regenerative point technique with renewal process theory the various reliability parameters MTSF, Availability, Busy period, Benefit-Function analysis have been evaluated.
