| 摘 要： | 利用RTDS及直流输电控制保护装置系统模拟再现了天广直流“2·14”100Hz保护Ⅰ段误动问题，并分别针对天广、高肇和兴安直流100Hz保护Ⅰ段进行仿真试验，试验结果表明，100Hz保护Ⅰ段延时设置值存在一个有效上限值，若设定值超过该有效上限值时将导致延时功能失效。

| Abstract: | With the RTDS （real-time digital simulator） and the DC transmission control ＆ protection equipments, the ＂2.14＂ mal-operation of stage Ⅰ of 100 Hz protection in Tian-Guang HVDC transmission system is simulated, and simulation studies on the stage Ⅰ of 100 Hz protections of Tian-Guang, Gui-Guang, Gui-Guang Ⅱ line HVDC transmission systems are carried out. The results show that there is an upper limit value for the time delay parameter of stage Ⅰ of 100 Hz protection. If the setting is over the limit value, the time delay function of the protection will be invalid. |
