The transients produced by the VCB include various frequencies. Therefore we need a transformer model for a wide frequency range. When an unloaded transformer is switched off the voltage highly depends on whether reignition occurs or not. The transformer is modeled by means of series connected Foster sections which represent the two-port impedance. The impedance sequence to the transformer core contains a nonlinear inductance representing transformer saturation. Several simulations are performed both with and without protective devices such as R-C suppression branches and surge arresters. The analysis shows that surge arresters have to be installed at the terminals and between phases in order to provide adequate protection. The R-C branches provide suppression of reignitions if the values of R and C are optimally chosen.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

One must ask the question of not how is it done today (NERC) but how it could be. The benefits of competition cannot be achieved without extensive use of high technologies (IT, systems approach to the problem). Furthermore, the incentives for using these technologies are hard to develop using a strictly engineering approach to the problem, or strictly regulatory, or economic. Their interdependence is critical to move forward. The IT tools are likely to be used first at the supply side (regulatory setup furthest along), the users needs a lot of help. The wire business is most complicated and it will require team work (engineers, regulators, economists) to move forward. Nonnegligible are the financial/political aspects of the industry transition. Long-term performance of the industry remains a real unknown.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat.

Of course, the technical content of the proposal is another critical element.

Decentralization, or all market participants have the rights to participate in decision making, is one of the directions. In this paper a decentralized structure is suggested to solve the problem using multi-agent technology. In this structure the information centralization is prevented and each market participant behaves rationally based on local information. Although the market participants make decisions to protect its own benefits, the minimum production and transmission cost of the whole system can be finally reached. This structure is based on the method proposed in another paper by the authors and implemented on computer via a multi-agent system using Java programming language. A demonstration on a 5-area test system shows that the suggested new approach is effective and promising.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

In order to find the reason for the phenomenon, measurements of resistive losses in a massive copper conductor were done in laboratory. Also, tests were performed in inductive furnace for metal melting. The conclusion is that the equivalent propagation depth value of the power must be taken into account instead of the equivalent propagation depth value of the electrical field. Also, the equivalent propagation depth in a cylindrical conductor has higher value than in the event of the conductive plane.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

The new technique has been implemented and tested in the EMTP (Electromagnetic Transients Program). It is based on a generic idea reusable in other transient analysis applications. The first objective is to significantly reduce computation time by avoiding unwanted simulation startup transients. The second objective is to increase the level of automation for the initialization of control block variables based on desired steady-state conditions. The new method has been used for a study in the Hydro-Quebec network with more than 40 controlled machines aggregating the generation of 30 GW. Comparing the fast steady-state solution obtained through time-domain simulation, with the desired steady-state operating conditions, provides validation.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.
