Abstract

In view of the Zhundong-Wannan UHV DC after construction and in accordance with present situation of power grid in Xinjiang

the feasibility on the safe stability and control measures of DC at lockout fault of Hazheng HVDC is studied

and the feasibility of cut off measures at DC lockout fault is analyzed. Such potential risk as flow transfer

new energy off net and action of the third defense line caused by cut off measure at DC lockout fault are analyzed

the optimal coordination scheme of the safe stability measures is proposed

which has a actual significance to the power transmission from Xinjiang and improvement of safe and stable operation of Xinjiang power grid.
