Power distribution terminal self-description method based on IEC61850 standard

The invention discloses a power distribution terminal self-description method based on IEC61850 standard. The power distribution terminal self-description method comprises the following steps of (1), writing a self-description file into a power distribution terminal file system; (2) establishing communication between a power distribution terminal and a power distribution main station, and actively applying a registration service by the power distribution terminal to the power distribution main station; (3) establishing a data model by the power distribution main station for the power distribution terminal according to power distribution terminal registration information, performing mapping for obtaining a subscription model, and transmitting the subscription model to the power distribution terminal; (4) automatically generating a communication point table by the power distribution terminal; and (5) triggering the power distribution terminal by the power distribution main station for starting a self-error-correction module, determining whether a subscription point number matches a point number which is supplied by the terminal and whether correct matching is performed through comparing the subscription model, the self-description file, the point number of the communication point table and a data domain name, and uploading the result to the power distribution main station. The power distribution terminal self-description method has function of improving efficiency and reliability in construction of a power distribution network, and laying a foundation for realizing a plug-and-plug function between the power distribution main station and the power distribution terminal.
