description The invention discloses a DCC program encryption authorization method for a 6RA80 DC transmission device, and belongs to the technical field of electrical transmission automation control. The method comprises the steps that a DCC chart is established, an unsigned double-integer type input pin and a Boolean type output pin are established in the chart, the input pin is used for presetting the number of authorization time days, and the output pin is used for controlling whether a user is authorized to use a DCC program or not; at a DCC program development end, three time authorization keys of the DCC program are calculated in combination with a serial number of a control unit of the user DC transmission device; when a user uses a DCC program, key matching verification needs to be carried out firstly, key verification of three time stages can be carried out, and the user is authorized to use when key matching succeeds. According to the method, the DCC program is bound with the serial number of the control unit,
