A waste recycling and generation plant experienced significant power and frequency fluctuations following a steam valve closure on the generators prime mover. The reverse power protection did not remove the electrical machine from the network as quickly as expected, and concerns were raised regarding the resulting damage potential. This paper presents the modelling of the system and the improved reverse...
The approach presented in this paper was applied to optimize the electrical inter-array cable systems for Offshore Wind Farms. It is compatible with both radial and branched design philosophies, and can optimize for total cable length, cable cost, and for operational losses. The method yields significant savings in design time and capital expenditure of cable. The full optimization of such a problem...
Sevoflurane has a lower blood-gas solubility and a less pungent odour than halothane; this may allow more rapid induction of anaesthesia. In a randomized, blinded study, we compared the induction characteristics of maximum initial inspired concentration of 8% sevoflurane and 5% halothane using conventional vaporizers in children aged 3 months to 3 years. There was no statistically significant difference...
