摘要
文中分析了高压交流输电系统中的磁可控电抗器运行的各种工况,介绍了其保护配置,针对性地提出了自动跟踪补偿额定电流的磁可控电抗器差动保护、基于时域平移平衡差动原理的磁可控电抗器匝间保护和控制绕组电压差动保护,并给出了验证这些保护原理的数字仿真、动模试验和现场运行结果。
This paper analyses various operation conditions of magnetically controlled reactor in HVAC transmission system, and introduces the protection configuration of reactor. Especially, reactor differential protection with automatic tracing and compensating rated current, reactor inter-turn fault protection based on time domain translation balance differential protection, and voltage differential protection of control winding are proposed. The results of digital simulation test, dynamic simulation test and field operation validate the proposed protections.
