摘要:The success of the Gantt chart has been proven by history and it still represents the most powerful tool for controlling small and medium sized projects and for presenting information to both management and those directly involved with the undertaking. One of the greatest strengt...

摘要:Protecting six-phase power transmission lines with stand-alone distance protection represents a major challenge for power system protection engineers. Not only are there 120 possible fault combinations for a six-phase line compared to the eleven for a three-phase line, but when t...

摘要:Questions are increasingly being asked about the response of standard protection schemes used for protecting embedded synchronous generators during abnormal operating conditions. Loss of grid and pole slipping are two such abnormal operating conditions, both of which can cause po...

摘要:This paper describes a new type of current transducer, which is based on the Rogowski Coil, and has several advantages over conventional current transformers. These include; a physically light transducer suitable for mounting on existing overhead line conductors, absence of satur...

摘要:This paper presents a new approach to pole slipping protection which eliminates the need for simulations, thus greatly simplifying the setting process. The new adaptive algorithm uses power measurements to ascertain if the generator is committed to a pole slip. In doing so it off...

摘要:The growth in the use of embedded generation operating in parallel with electric utility distribution systems has increased the importance of loss of grid protection. A new loss of grid protection algorithm is described in this paper which has been designed to be amenable to incl...

摘要:This paper examines the complications encountered when using distance relays to protect six-phase transmission lines. By examining the impedances seen for various fault conditions, it demonstrates how a full scheme six-phase distance relay and a combination of three phase relays ...

摘要:This paper describes research into new techniques for automatically detecting loss of earth for an embedded generator. The techniques investigated take advantage of the parasitic impedances associated with a practical generator. These are used to determine whether or not the syst...

摘要:This work examined a new approach to providing protection for the power supply network by monitoring the propagation of the high frequency transients through the network. It builds on techniques previously developed to protect feeder circuits and is able to provide details of the...

摘要:Wound current transformers are used in virtually all protection schemes associated with a power system plant. The potential for using them as the primary transducer for monitoring high frequency currents as well as the power system frequency components provides the basis for exte...
