These values are computed for a nonlinear load based on simulated and measured data, after which they are compared to the values obtained from the IEEE Working Group Definitions of Power. It is shown that while these definitions can be used to a certain extent to quantify a disturbance, identification of the load is not always possible, as the values obtained for the various power components can to a large extent be influenced by loads parallel to the primary load. This article shows further that it could be possible to identify loads contributing to the voltage distortion at the point of common coupling by means of correlation.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

The size of motors that can be served from these inverters is limited by the inrush requirements of the motors and the limited overload capability of the inverters. This paper presents two methods to limit motor starting inrush currents within an appropriate range, in order to allow increased motor starting capability without exceeding the inverter overload limits. Both methods work by introducing voltage sags during the motor starting. Comparisons are made between the two methods, and are also compared with the existing method which has no current limitation. Both methods are also compared with acceptable sag and harmonic distortion limits. Conclusions are offered regarding the viability of these methods.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

An open-loop control Volts per Hertz boost strategy is used in order to compensate the speed loss during the three-phase balanced voltage sags.

The control structure neither requires the service of a PLL nor the sector information of the utility voltages. This makes the control scheme robust and simple. Moreover, one-cycle control makes the switching frequency of the devices constant. This simplifies the process of design of passive filters to eliminate higher order switching harmonics. The semiconductor devices are operated with a switching frequency of 1kHz so that GTOs or high power IGBTs can be used for medium power applications. The viability and effectiveness of the scheme are confirmed through detailed simulation studies.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

The overvoltage protection type has an influence on the system behaviour and on the interruptions and voltage sags experienced by power system customers. In this paper, measurement results showing the effect of overvoltage protection type on established faults in an unearthed medium voltage overhead line network are presented. Detailed results of fault frequencies and fault types are shown. Further, a probability function is established to describe the influence of overvoltage protection type on voltage sags experienced in the network. This latter aspect is important when limiting the effects of interruptions and voltage sags for sensitive customers.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

These calculations are performed with samples of the monitored waveforms, at a sample frequency equal to N times the nominal frequency of waves. Conventional algorithms regard N as a constant integer. When the actual frequency has a deviation from its nominal value, errors are introduced in the calculations, and averages are used over several cycles to reduce these errors. However, for instantaneous quality parameters, these calculations must be performed every cycle for quick disturbance detection; averages are impracticable. The purpose of this article is to introduce a method to minimize these errors making N variable and a noninteger.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.
