Japan, Feb. 27 -- TOSHIBA CORP,TOSHIBA ENERGY SYSTEM&SOLUTION CORP has got intellectual property rights for 'RESONANCE SUPPRESSION DEVICE, POWER TRANSMISSION SYSTEM, AND RESONANCE SUPPRESSION METHOD.' Other related details are as follows:
Application Number: JP,2022-066562
Category (FI): H02J3/11,H02J3/00,H02J3/01
Stage: PROBLEM TO BE SOLVED: To provide a resonance suppression device, a power transmission system, and a resonance suppression method capable of suppressing an increase in harmonic voltage expansion multiple and suppressing harmonic interference when AC cable power transmission is used.SOLUTION: An AC power transmission system according to an embodiment includes a first transformer connected to a power supply of a power system and transforming a voltage to supply power to the power supply, and a first AC cable connected to the first transformer. In the AC power transmission system, a harmonic resonance suppression device includes a first capacitor and a setting unit. The variable capacity capacitor is connected to the AC power transmission system. The setting unit sets the capacitance of the first capacitor to a value such that the resonant frequency in the AC power transmission system does not resonate with any of the third, fifth, and seventh odd harmonics.SELECTED DRAWING: Figure 1 (Grant)
