Several operating modes of unloaded line are introduced in this paper firstly,and adaptability analysis on protection and automatic security device of various modes is proposed? When the operating power supply of breaker in state of cold standby or main-tenance is shut down,impact on the protection and automatic security device of unloaded line is emphatically analyzed,and counter-measures are proposed? Adaptability of automatic switchover device is analyzed when the status of breaker changes through various examples? Finally,impact on strategy of stability control system in operating modes of unloaded line is discussed,and relevant pro-posals are put forward for the design of stability control system.
