The work has been conducted in conjunction with Scottish Hydro Electric PLC. The fault diagnosis system is based on a hybrid object-oriented AI technique. The method developed utilises abductive inference. This technique is demonstrated to realise some improvements when compared with fuzzy logic and takes into account the current practical limitations in the design. The method is based on processing SCADA (supervisory control and data acquisition) messages, extending the arrangement of the knowledge acquisition process and applicability of circuit breakers and relays. The potential benefits and implications of adopting such an abductive fuzzy knowledge based system are demonstrated in this research, and include a user friendly inference engine, adaptability, and KBS update.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.

On the other hand, by using DGs and DESSs, power quality and power supply reliability can be reinforced, and unbundled power quality services in demand side can be realized by which customers can select power quality according to their demand objectives. Therefore, several proposals of new type power delivery systems for realizing the above are published. This paper introduces one of these new type power delivery systems named FRIENDS (flexible, reliable and intelligent electrical energy delivery system).

The approach utilises pattern recognition to provide adaptive and timely responses throughout the entire grid. Pattern recognition offers an intrinsically simple (minimal computation) and reliable method, an essential for a practical protection which must function whenever it is needed. To allow an affordable solution against multiple contingencies to the grid, load shedding is proposed, as it avoids the inordinate expense of redundant equipment for withstanding unpredictable situations. This offers a modest cost protection at only a tiny fraction of the tens of millions of dollar costs incurred by the 2nd July and 10th August 1996 US power blackout incidents.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.

This ballast is composed of a single-ended resonant-type inverter, which can supply high frequency (100 kHz) power to a 70 W metal-halide lamp, one of the HID lamps, without an acoustic resonance. The proposed ignitor is composed of a magnetic pulse compression (MPC) circuit, which can generate sufficiently high voltage pulses for the instantaneous restarting of the HID lamp. The characteristics of this proposed inverter and ignitor circuits for HID lamps are described in this paper. Based on the results obtained from experiments, the proposed circuits are more useful than the conventional one.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.

The field from sources such as transformers, busbars and cables was studied. Shielding was performed at the sources rather than at the affected areas. Experimental, analytical and numerical methods were used. It was observed that a shielded transformer gives a good field reduction when contrasted to an unshielded one. The field of busbars and its mitigation was analysed using finite elements. Geometry and shielding materials were varied, it was found out that open shielding is more effective when using conductive rather than ferromagnetic materials. Two 1-phase coils, fed by low voltage and low current, mimicked the source performing active compensation of the 3-phase busbars.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.

Notably in the literature, either back propagation (BP) or Hopfield neural networks (HNN) has claimed to provide quality control signals to achieve the desired harmonic reduction results. This paper evaluates the predictability of BP and HNN in terms of convergence behaviour and learning capability, as applied to the reduction of load generated current harmonics in a variable speed DC drive. Using the same real current harmonic data, our test results confirm that BP has a larger dynamic harmonic range whereas discrete HNN, due to its interconnection structure, needs larger size of memory map.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.

The noncontact feature of the ICPT (inductively coupled power transfer) system is significant in that the charging is transparent to the driver. When the driver stops at the loading platform, the charging unit automatically senses the vehicle and begins charging if required. Four charging bays (buried under the ground) are provided allowing opportunity charging throughout the day. This minimises the necessary on-board batteries, and therefore the vehicle weight, while still allowing the vehicles to be operated continuously.","PeriodicalId":330989,"journal":{"name":"PowerCon 2000. 2000 International Conference on Power System Technology.
