摘要
针对基于电压源换流器的高压直流输电(High-Voltage Direct Current,HVDC)系统存在系统保护反应时间长、直流断路器断电能力不足等问题,提出全新的高压直流输电保护配置方案。一方面,分析高压直流输电系统故障的基本特征和处理原则;另一方面,设计以平波电抗器作为线路主保护设备、以纵联差动保护作为后备保护的方案,具有一定的实用价值。
In order to solve the problems of long system protection response time and insufficient DC circuit breaker power cut-off capability in High-Voltage Direct Current(HVDC)system based on voltage source High-Voltage Direct Current#Back to back,a new scheme of High-Voltage Direct Current#Back to back protection configuration is proposed.On the one hand,the basic features and treatment principles of High-voltage direct current#Back to back system faults are analyzed.On the other hand,the scheme of using the flat wave reactor as the main line protection equipment and the Longitudinal differential protection as the backup protection is designed,it has certain practical value.
