摘　　要：为正确解决糯扎渡水电站直流孤岛运行方式下系统的稳定及判别方法问题,指出普洱换流站有两种孤岛运行接线方式,并以孤岛运行方式1为例,分析了糯扎渡直流双极投产后2014年丰大极限方式、枯小方式系统的稳定性及确保系统稳定的措施,并给出了元件故障引起的孤岛运行方式自动判别方法和配置方案,可有效识别直流孤岛运行方式,从而正确执行孤岛方式下安稳策略并解决系统稳定问题。In order to solve the problem of stability analysis and discrimination of Nuozhadu UHVDC in island opera lion mode correctly, two different structure diagrams of Nuozhadu UHVDC island operation mode are indicated. Taking the first mode as an example, the stability calculation is conducted on the basis of data of China Southern Power （;rid in 2014 in which the Nuozhadu HVDC is put into production. And the method and configuration of automatic island operalion mode discrimination is put forward according to the status of elements. Island operation mode can be identified effeclively so as to execute the stability strategy and solve the stability problem correctly.
