METHOD FOR MATCHING AN ASYMMETRIC THREE-WIRED ELECTRIC TRANSMISSION LINE WITH ELECTRIC LOAD AT FREQUENCIES OF EXPRESSLY HARMONIC COMPONENTS OF CURRENTS AND VOLTS

摘要

A method of matching an asymmetrical three-phase three-wire high-voltage power line with an electrical load at the frequencies of all clearly expressed harmonic components of currents and voltages, which consists in the fact that the initial information about the voltages and currents in the line through the interface devices or sensors is fed to the processor, characterized in that in the processor the conditions for matching all clearly expressed harmonic components of currents and voltages of an asymmetrical three-phase three-wire power line with an electrical load for each wire of the line are checked in turn by comparing the actual and reference values of load resistances, voltages at the end of the line or currents entering the load, and control signals are generated for filters of higher harmonic components of currents and voltages of various modifications and correcting bodies, which can be used as on-load tap-changers of power transformers, autotransformers or automated technological complexes, energy storage, active power sources, such as low-power hydroelectric or other types of power plants, synchronous compensators.
