The invention discloses an intelligent transformer substation relay protection test fault positioning method and system. The method comprises the steps that alarm information and data are preprocessed, repeated data are removed, and alarm information and the data which can be used for direct reasoning are removed from an original table and are stored separately; and fault positioning is performed,an existing template is used to carry out fault positioning on the alarm information and the data which can be used for direct reasoning, and for the alarm information and the data which need complexreasoning, parameters obtained by carrying out deep learning training by an RNN recurrent neural network are used to carry out fault positioning. In the invention, automatic positioning of relay protection test faults is realized, a fault processing speed is greatly improved, and test efficiency of a relay protection device is greatly increased.
Description
technical field [0001] The invention relates to the field of automation of digital relay protection testers, in particular to a method and system for fault location of relay protection tests in intelligent substations based on deep learning. Background technique [0002] With the gradual promotion and application of digital and intelligent substations, the IEC 61850 standard is widely used in substation automation systems. IEC 61850 enables the internal data of the relay protection device to have strong self-describing characteristics. The information model is established according to a unified method and data class. The operation brings the foundation and provides an opportunity for the automation of the digital relay protection tester. [0003] At present, the digital relay protection tester is mainly used for debugging in the factory joint debugging and on-site debugging of the relay protection device of the smart substation. The digital relay protection tester is to ma...
