Assume that a recently commissioned generating station in Oman has an overall efficiency of 15% and 0.75kg of coal is burnt per kwh by the station. Evaluate the energy value of coal? Set up a new power plant in Ibri, which has three generators. One generator is coupled to turbine which is driven by energy from natural gas and the other two generators are coupled to turbines which are driven by energy from steam, how will you connect this power plant to a 220KV grid? Enumerate its operation with suitable schematic
