Abstract

The invention belongs to the field of simulation and particularly relates to a distribution network fault simulating method, a distribution network fault simulating device and a distribution network system. The distribution network fault simulating device comprises a double-source power supply circuit, a simulation protecting module, a plurality of simulative distribution terminal modules and a simulative fault recovering module; and the distribution network fault simulating device can simulate on-site equipment and a fault, simulate the communication of the simulation protecting module and the plurality of simulative distribution terminal modules of a transformer substation with a simulative distribution main station, simulate an actual load current, simulate a fault current and report fault information, simulate to execute remote-control switching-on and switching-off operations to simulate the cutoff of the fault current and switch on a normal current. The distribution network fault simulating device can completely replace a protective device and actual hardware equipment of a distribution terminal, reduce the field occupancy of the equipment and the wire-connecting and debugging workload of the equipment, save manpower and improve the working efficiency.

Description

technical field [0001] The invention belongs to the field of simulation and simulation, and in particular relates to a distribution network fault simulation method, device and distribution network system. Background technique [0002] In the existing power distribution automation system, a power distribution network is usually formed by the power distribution master station system and multiple power distribution terminals; AC voltage and current are applied to the power distribution terminals, when the applied AC current exceeds the rated measured value and remains for a period of time , when this time exceeds the set value of a period of overcurrent protection time in the terminal, the terminal will report the total fault signal and overcurrent information. The power distribution master station system analyzes and processes the information reported by multiple terminals to determine the location of the fault; and according to the pre-established plan of the master station, ...
