The techniques used to locate the capacitor banks in the system consider such issues as voltage control, losses, and contingency performance. The effects of harmonics and the resonance conditions that such transmission capacitors may create are typically not considered in the strategies employed to locate the banks unless specific circumstances dictate the need for a detailed study. Due to the large number of capacitor locations to be considered, the number of switching steps in a particular bank, and the changes in the system caused by contingencies, the number of scenarios to be studied often exceeds that which is reasonable for detailed harmonic studies. Because most capacitor applications utilize automated contingency analysis techniques such as those found in PSS/E, it is advantageous to incorporate harmonic screening into this accepted framework. The tool described in this paper can take PSS/E output files and perform the harmonic screening of the system for the contingencies of interest in a batch mode. This tool is based on standard assumptions for harmonic modeling and simulation and incorporates sparse matrix techniques in order to evaluate the larger system models common to transmission systems.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

PF-compensated low-distortion AC/DC front-end pf补偿低失真AC/DC前端

This output voltage is unregulated and contains approximately 4% voltage ripple for a 3-phase system. The resulting input line power factor is a function of the load reactance, and is typically nonunity. If the load reactance is heavily capacitive, a means must be available to handle the large inrush current, otherwise, the input breaker may trip open, resulting in an embarrassing situation, necessitating the addition of inrush current limiting circuitry. The harmonic input current usually is above 10% for the 5/sup th/ and 7/sup th/ harmonics, again a highly unsavory situation, but one that has been with us for quite some time. In essence, what would be desired from a front-end would be the following properties: regulated output voltage, unity PF, inrush current limiting, harmonic line distortion <3 %. The switched matrix AC/DC front-end solution achieves all the above properties, and is presently technically feasible as will be shown in the following article. It simply consists of six unidirectional switches, typically field effect transistors, and a control printed wiring board that provides the proper pulse-width-modulation and sequencing to the six switches. The control algorithms for the PWM and sequencing are derived from prior work that is readily available in the literature generated by Messrs. Venturini, Ishiguru, and Holmes. What makes the switched-matrix more feasible today than in the past is the tremendous increase in computational speed and power that is required to realize the control algorithm, in addition to new generations of fast power semiconductors. This work makes the use of PSPICE to simulate this innovative solution and determine some of its characteristics.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.
