• ### Electric vehicles' impact on british distribution networks

Publication Year: 2012, Page(s):91 - 102
Cited by:  Papers (21)
| | PDF (1163 KB)

Battery charging of electric vehicles (EVs) will increase the power demand in distribution networks. It is anticipated that this will cause voltage drops, thermal overloads and an increase in losses. The severity of the impact will depend on the EV owners' behaviour. A generic three-phase low voltage (LV) residential distribution network model was used to evaluate the effects of EV battery chargin... View full abstract»

• ### Preliminary evaluation of the energy-saving effects of the introduction of superconducting cables in the power feeding network for dc electric railways using the multi-train power network simulator

Publication Year: 2012, Page(s):103 - 109

| | PDF (198 KB)

Thanks to the recent developments, the superconducting cables using high-temperature superconducting (HTS) materials are now expected to reduce feeding losses in the power supply network for DC electric railways. However, by connecting the HTS cables with the normal conducting wires electrically, heat intrusion is inevitable; to suppress heat intrusion to an acceptable level, interconnection becom...

• ### Electrothermal modelling of the railroads catenaries

Publication Year: 2012, Page(s):110 - 118
Cited by:  Papers (1)
| | PDF (540 KB)

Feeding catenaries sometimes induces mechanical problems because of high temperature gradients, particularly for power supply voltage of continues tensions from 750 to 3000 V, contrary to the supplies in alternative tensions used of the order of 25 000 V. One of the major reasons of these problems comes from both high temperatures reached in operating configurations and surrounding conditions. The... View full abstract»

• ### Fault location for aircraft distribution systems using harmonic impedance estimation

Publication Year: 2012, Page(s):119 - 129
| | PDF (776 KB)

The demands for more electric aircraft will increase the power distribution requirements of future aircraft electrical distribution systems. To increase safety and reduce aircraft maintenance times on the ground, there is also a need for system condition monitoring to quickly identify and locate any electrical faults which may develop. The work presented in this study forms an initial study into... View full abstract»

• ### Synchronisation control of trains on the railway track controlled by the moving block signalling system

Publication Year: 2012, Page(s):130 - 138
Cited by:  Papers (4)
| | PDF (400 KB)

It has been widely expected that moving block signalling will realise greater line capacity through shortened headways between trains. However, under the condition in which all trains are individually and manually controlled, the actual effect of introducing moving block signalling is marginal. To make full use of moving block systems, the author proposes a new scheme in which a train that follows... View full abstract»

• ### Load flow analysis and future development study for an AC electric railway

Publication Year: 2012, Page(s):139 - 147
Cited by:  Papers (11)
| | PDF (892 KB)

This study presents a forward/backward sweep (FBS) load flow method for AC autotransformer (AT)-fed electrical railway networks considering dynamic movement of trains. Field measurements of Tehran-Golshahr suburban railway are compared with simulation results. Moreover, effects of the time headway reduction on this suburban railway and its transmission power supply system are investigated. Then, t... View full abstract»

• ### Multi-objective design of a hybrid propulsion system for marine vessels

Publication Year: 2012, Page(s):148 - 157
Cited by:  Papers (3)
| | PDF (364 KB)

Hybrid vehicles offer the advantages of both conventional and electric vehicles. Improved fuel consumption is generally the main driver for these systems with the option of silent, emission-free operation also being a big advantage. Marine hybrid vehicles however, do not experience significant recovery of energy via regeneration, because of their operating profiles. Fuel savings can be realised by... View full abstract»

• ### Generation control system for improving design and stability of medium-voltage DC power systems on ships

Publication Year: 2012, Page(s):158 - 167
Cited by:  Papers (21)
| | PDF (645 KB)

Voltage stability in medium-voltage DC (MVDC) power systems on ships is a key design goal. MVDC bus voltage stability can be impaired because of the presence of power electronic converters that can induce negative incremental resistance instabilities. This study presents a control strategy that stabilises MVDC bus voltage in the presence of destabilising constant power load converters. A state-fee... View full abstract»
