摘要

高压交流SF

断路器在特高压直流输电中承担无功补偿与谐波滤除任务，由于电压等级高，投切容量大、交流滤波器组断路器的频繁动作会引起触头烧蚀甚至引发事故。针对某±800 kV换流站实际线路配置，利用PSCAD软件对可能出现的工况进行建模分析，研究了750 kV滤波器组断路器合闸电阻阻值对合闸暂态的影响及合闸电阻不同状态下的暂态电流特征，提出合闸电阻状态诊断方法。结果表明，合闸电阻在300～400 Ω时在4类滤波器上均表现出良好的综合性能，为主电容过电压、涌流和避雷器过电压提供了较优的抑制效果。通过谐波分析、涌流峰值时刻及三相合闸一致性判据，可有效识别合闸电阻故障。提出动态电阻法结合神经网络、SF

分解组分分析及历史投切数据校正3种电寿命评估方法，动态电阻法预测误差可控制在4%以内。在此基础上开发了合闸电阻在线监测系统，实现了断路器状态的实时评估，为750 kV滤波器组断路器合闸电阻的分级运维策略提供了技术支撑。

Abstract

High-voltage AC SF

circuit breaker in ultra-high-voltage DC transmission systems is responsible for reactive power compensation and harmonic filtering. The frequent operations of AC filter circuit breaker，due to high voltage level and large switching capacity，can cause contact erosion and even lead to failures. Based on the actual line configuration of a converter station，in this paper the PSCAD is used to model and analyze possible operating conditions，the influence of closing resistance on switching transients and the current characteristics under different resistance states is investigated，and the diagnosis methods of closing resistor are proposed. The results show that then the closing resistor in the range of 300～400 Ω，it exhibits excellent comprehensive performance across four types of filters and provides superior suppression in the field of overvoltage across the main capacitor，inrush currents and overvoltage on arrester. By applying such criteria as harmonic analysis，the peak timing of inrush current，and the consistency of three-phase closing，as well as the faults in the closing resistor can be accurately identified. Such three electrical life assessment methods as the dynamic resistance method combined with neural networks，SF

decomposition product analysis，and historical switching d

ata correction are proposed. The error predicted by the dynamic resistance method is controlled within 4%. On this basis，the on-line monitoring system for closign resistor is developed，enabling real-time assessment of circuit breaker's conditionand providing technical support for the grade operation and maintenance strategy of closign resistor in 750 kV filter bank circuti breakers..
