摘要
500 kV高温超导限流器技术是目前世界上电压等级最高的高温超导限流器技术,它应用在电网中可有效解决由于电网结构加强产生的主干电网短路电流水平过高问题,同时又不降低电网运行的可靠性和灵活性,但目前还没有一个成熟的500 kV高温超导限流器电气主接线方案。根据目前高温超导限流器技术和设备最新研究进展,提出了4种500 kV高温超导限流器接入系统的电气主接线方案,并通过可靠性、保护配置和造价等的综合比选提出推荐方案,该方案适用于超导限流器可靠性不高且严重故障后需要立即切除的设备发展现状,故障后需要立即切除的技术发展现状。
The state of art 500 kV high temperature superconducting fault current limiter operates at the highest voltage level. The use of 500 kV high temperature superconducting fault current limiter ean reduce short-circuit current in the system without reduction of reliability and flexibility. However, there is no well accepted main electrical connection for the limiter. Four different kinds of main connection schemes are discussed. Recommendation is made after comprehensive comparison on reliability, protection configuration and equipment cost. The recommended scheme is suitable for low reliability 500 kV high temperature superconducting fault current lirniter which must be removed immediately after failure occurrence.
