基于混合无功功率补偿的交直流混联线路潜供电弧抑制措施
Suppression Measures for Submarine Arc in AC/DC Hybrid Transmission Lines Based on Hybrid Reactive Power Compensation
摘要
Abstract
With the increase of voltage level and transmission power,the reactive power of the system changes more frequently,which is not conducive to arc extinguishing and seriously threatens to the safe and stable operation of transmission lines.Based on the AC/DC hybrid reactive power compensation(HRPC)line,the influence of the compensation degree of the hybrid reactive power compensation(HRPC)device on the submarine current and recovery voltage is studied.The measures of hierarchical controllable high reactance and small reactance linkage control are analyzed to suppress the submarine arc,and an improved timing control strategy for bypass circuit breakers is proposed.The results show that when the series compensation degree is 20%,the compensation degree is 70%,and the small reactance is 700 mH,the amplitude of the submarine current and recovery voltage is the smallest,and the suppression effect is the best.In addition,the control strategy of using the bypass circuit breaker to disconnect after the extinguishing of the submarine arc can further accelerate the extinguishing rate and improve the success rate of single-phase reclosing.The research results provide theoretical basis and technical support for the application of HRPC in long-distance high-capacity hybrid transmission lines.关键词
