摘要
高压直流输电系统中大触发角监视的目的是检测和限制主回路设备在大触发角运行时所受的应力。介绍了高压直流输电系统中的大角度监视原理，分析了会引起大角度监视报警的各种因素及动作后果。以华新站发大角度监视报警为例，结合该换流站的软件原理，对大角度监视的动作过程进行分析，提出了高压直流输电系统发大角度监视报警时的注意事项，以保证设备的安全运行。
In HVDC system, the purpose of HAS is to detect and limit the stress of main equipments which are running under high angle situation. This paper analyses the principle of HAS, the factors and protection con- sequences of HAS protection. Combined with the software principles of convert station, the paper analyses the process of HAS alarm protection, raises the precautions when HAS is alarming, with the alarm of HAS in HuaXin convert station as example.
