Flexible Compensation Control Strategy Considering Bamboo-contact Single-phase-to-ground Fault Characteristics
摘要
Abstract
Aimed at the issue of forest fires caused by bamboo-contact single-phase-to-ground faults in power distribu-tion lines,a flexible compensation control strategy which takes into account the characteristics of such faults is pro-posed.First,a 10 kV prototype test platform was set up to analyze the ignition process under bamboo-contact single-phase-to-ground faults.Based on the ignition time of vegetation and the characteristics of impedance changes,the effec-tive value of the target voltage for compensation control was determined,and partial optimization methods were used to solve the optimal phase of the target voltage,so as to address the issue of"blank period"in flexible compensation.Then,a compensation current calculation method based on Newton iteration method was proposed,which does not re-quire precise system-to-ground parameters.By combining the zero-sequence voltage and compensation current during the regulation process,a precise control of the compensation target voltage in the fault phase was achieved.Finally,through simulation analysis and experimental verification,it was shown that the proposed method can effectively pre-vent and control the ignition accidents caused by bamboo-contact single-phase-to-ground faults.关键词
