Disclosed are a system and method for detecting a vulnerability of an Internet of Things in Power Systems (IOTIPS) protocol based on fuzz testing. The system includes: a protocol configuration module configured to configure a protocol to be detected and a data frame of the protocol to be detected; a sample generation module configured to: after loading the protocol and the data frame configured by the protocol configuration module, configure a mutation strategy based on the loaded protocol, and generate a test sample based on the configured mutation strategy; and an execution monitoring module configured to transfer the test sample generated by the sample generation module to a device to be detected for testing, perform link management and test execution, store a test result, and generate a detection report.

A device for simulating intermittent arc grounding faults in a power distribution network includes a sliding rail, a first and a second support frames, an insulated electrode disk, and an electrode disk motor. The first support frame is fixed on the left side of the slide rail, and the position of the second support frame relative to the first support frame can be adjusted through the sliding rail. The second support frame is provided with an electrode disk motor for driving the insulated electrode disk to rotate. An upper and a lower conductive bars are installed on the first support frame, their adjacent ends provided with an upper and a lower arc-shaped conductor sheets, and the insulated electrode disk having two circles of conductive pillars is located between the conductor sheets. The conductor sheets are respectively installed on the side of the conductive bars close to the conductive pillar.
