Abstract: Embodiments of this application disclose a resource configuration method and a communication apparatus. The resource configuration method includes: An integrated access and backhaul mobile terminal (IAB MT) determines a first time division duplex (TDD) configuration based on a first transmission mode. The first transmission mode includes a transmission mode on at least one frequency domain resource set in a plurality of frequency domain resource sets of an integrated access and backhaul distributed unit (IAB DU). The first TDD configuration is a cell-common TDD configuration or a dedicated TDD configuration. The IAB MT determines a resource location based on the first TDD configuration. It can be learned from the technical solution that the IAB MT selects the corresponding TDD configuration based on the transmission mode on the at least one frequency domain resource set, to determine the resource location.

Abstract: A detection system and method for rotor dynamic turn-to-turn short circuit fault of synchronous generator are disclosed. The system includes a motor, a synchronous generator, a current transformer, an acquisition card, an infrared temperature sensor, a temperature acquisition instrument and a control terminal. The rotor winding dynamic turn-to-turn short circuit fault of synchronous generator is detected and located by measuring the double judgment standards of the temperature signal of rotor winding and the three-phase current signal of stator winding. The method is easy to operate and has high sensitivity. The detection and location process of the fault is efficient and reliable. The dynamic turn-to-turn short circuit fault can be detected in the early stage of the formation of rotor static turn-to-turn short circuit, so as to reduce the loss of power plant fault shutdown and better meet the needs of practical application.
