The main objective of this Paper was to evaluate the outage cost due to system downtime (Turbine failure) of Egbin Thermal power station from the year 1999 to 2008. The result of the analysis carried out revealed that for the whole ten years under review that there was a power generation loss of 46 percent of the Installed capacity putting the performance of the power station at 54 percent. Fur...

A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practice in Bulgaria, it seems feasible on an industrial scale and so it may help to ease Portugal’s reliance on imports of nitrogen fertilizer and thereby contain the outfl ow of Portuguese funds. The d...

Abstract Because of the increasing demand for energy in recent period, it has become necessary to intensify study field evaluating performance gas station under first and second laws efficiency. The exergy losses stations are represented by compressor, combustion chamber, turbine. Therefore, this work aims analyze a 55 MW Taza power station. investigation demonstrated that most significant misf...

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...

We consider a CDMA cellular wireless access network that handles various classes of calls that are characterised by different bit rates and Eb=N0 requirements. For the uplink of such a system we study the relationship between power control, admission control and user mobility. We compare two methods for power control: Constant Received Power Control (CRPC) in which the total power received at e...

In this paper, we study the feasibility of a batteryless wireless sensor supplied with energy by using microwave power transmission (MPT). If we perform co-channel operation of MPT and wireless local area networks (WLANs) for the sake of spectral efficiency, a time division method for MPT and WLAN communications is required to avoid serious interference from MPT to WLAN data transmissions. In a...
