Abstract: This paper introduced the basic principle of 1 000 kV high voltage controllable reactor of the UHV substation.In addition, it combined the first engineering application of the high voltage controllable reactor, proposing two different configuration schemes for the reserve configuration and comparing them.Besides, it demonstrated analysis to verify the feasibility of the reserve schemes and provided a specific design plan. The result shows that the fixed high voltage reactor could be an alternative for the high voltage controllable reactor, and this plan passes the engineering practice verification.
Key words: UHV; 1 000 kV stepped controllable shunt reactor; spare phase
