Embodiment Construction
[0091] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0092] like Figure 1-Figure 8As shown in the figure, a method for locating faults in smart substations based on a gated cyclic unit network includes the following steps: Step 1: For different intervals, such as line interval, transformer interval, busbar interval, and central switch interval, four types of intervals are collected. The alarm signals sent by the relevant equipment when the secondary equipment and its network ports, optical fibers, switch ports, etc. fail, construct the alarm signal set of each interval under each fault scenario and its corresponding fault location. The specific operations are as follows:
[0093] 1) The station control layer equipment collects the alarm signals sent by the related equipment when the next secondary equipment fails in each interval, and forms the alarm signal set and its corresponding faul...

The invention discloses a fault location method for an intelligent substation based on a gated cyclic unit network, comprising the following steps: Step A: for each fault scenario of secondary equipment in each interval of the intelligent substation, collect alarm signals from related equipment to form an alarm Signal set and corresponding fault location; Step B: Construct GRU networks for each interval respectively, add a fully connected Dense layer after that, and finally add a Softmax classification layer, and then construct a GRU fault location model for each interval; Step C: For each interval The GRU fault location model is trained, and the respective training data are sent to the respective training data for fault location training, and each parameter in the GRU fault location model is optimized with the accuracy rate as the index; after the GRU fault location model is trained, it is sent to its own test The data is tested, and the accuracy of each GRU fault location model is calculated. The invention can accurately locate the fault of the secondary system of the substation, and provide efficient and accurate auxiliary decision-making for the operation and maintenance personnel.
Description
technical field [0001] The invention relates to the technical field of fault location of a secondary system of an intelligent substation, in particular to a fault location method of an intelligent substation based on a gated cycle unit network. Background technique [0002] The safe and reliable operation of smart substations is very important to the operation of the power system. When the secondary system of the smart substation is abnormal and generates a large number of alarm signals, it is difficult for the operation and maintenance personnel to extract useful information from it, and it is difficult to accurately determine the fault location. [0003] Many researches have been done on the fault location of the secondary system at home and abroad. The patent "Method and System for Fault Location of Substation Secondary Circuit Based on Graph Neural Network" proposes a fault location method for secondary circuit of substation based on graph neural network, extracts and a...
