During power restoration, the energization of a no load transformer can lead to high overvoltages, the amplitude being sensible to initial conditions. This document describes an approach based on the AUTO program, which is a complementary tool to EMTP, and may help the understanding of the behaviour of the electrical circuit. The case of a progressive energization of a transformer is described, with a progressive energization from the hydraulic power plant of Pied de Borne towards the thermal power plant of Tricastin. Tests have been performed by the Exploitation Department, with a progressive voltage rise, the network having a resonant frequency at 164 Hz, with a distortion of the voltage above 0.6 Un, and the presence of the third harmonic, the maximum being obtained after ten seconds. A single phase of the network has been used and equations of this network have been solved with the AUTO program, showing that the network can generate the third harmonic, depending also on the value of the flux in the network, the third harmonic being reached for a value of 0.65 kWh; it has also been validated by EMTP calculations. A time domain approach, with programs like EMTP is however necessary to calculate the maximum overvoltage in a three phase network, especially when the phase to phase insulation of the equipment is concerned. In the case of high overvoltages, palliative solutions can be suggested like synchronizing devices in circuit-breakers, circuit-breakers with resistances and zinc-oxide arresters.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

Independent of the particular tool employed, excellent accuracy and simulation speed can be expected when linear circuits are analyzed. Although power electronic devices are nonlinear, in the realm of power system simulation, individual switches, diodes and thyristors are typically modelled as piecewise linear components which are either in a state of conduction or nonconduction. Consequently, it is more appropriate to consider these devices as linear elements which change the topology of a circuit as they switch from periods of conduction to nonconduction or vice versa. If other electrical components within the system are linear, then the entire system including power electronics may be considered linear, but time varying. Taking this perspective, it is easily seen that the ability of a simulation tool to accurately and efficiently model a power electronic circuit does not depend on its ability to accurately model the circuit behaviour during periods of consistent device conduction or nonconduction. During such periods the circuit is fully linear and nearly any solution method is adequate. Accuracy and efficiency of a solution technique is therefore measured only by a method's ability to correctly identify the precise times at which a power electronic device switches between conduction and nonconduction intervals and to appropriately re-initialize all system state variables.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.

Here in the United States, the change began with a variety of Federal regulatory initiatives geared at transforming wholesale markets, and rapidly spread to state backed initiatives directed at transforming retail electricity service. The 1992 Energy Policy Act and FERC's related open access Orders 888 and 889 introduced new entities to the power markets and required major changes to the provision and pricing of transmission service. Other institutional changes will occur in response to the FERC's Order 2000 on Regional Transmission Organizations (RTOs) and impending Federal reliability legislation. Nearly apace with Federal initiatives, some states moved from the model of command and control regulation to one that includes competitive generators and load servers as mixed with regulated transmission and distribution utilities. Other states have decided either not to open their electric industry up to retail competition, or are studying the issue. These numerous and rapid changes have created a great deal of uncertainty among market participants regarding their roles and obligations, and created concerns regarding the long term reliability of the industry. This presentation focuses on the implications such changes may have for the status of generation resource adequacy.","PeriodicalId":253534,"journal":{"name":"2001 IEEE Power Engineering Society Winter Meeting.
