The invention discloses a quantum key regulation and control method for remote control machine terminals of an intelligent substation, and the method comprises the steps: making full use of the number of the remote control machine terminals, obtaining feature numbers through the judgment of the remote control machine terminals according to the numbers of the remote control machine terminals and the content of a first quantum key set, and collecting all the feature numbers through a master station server, and then generating a public key; the master station server configures the public key into different private line keys for each remote control machine terminal and transmits the public key in a second quantum key set, different remote control machine terminals correspond to different private line keys, and the content of each second quantum key set is different, so that the decoding difficulty is greatly increased; according to the invention, a finer, safer and more reliable network key ring structure can be
