Distribution network automation simulation system and distribution network fault simulation method

Abstract

The embodiment of the invention discloses a distribution network automation simulation system and a distribution network fault simulation method. The distribution network automation simulation systemcomprises at least one transformer substation module and at least two cable distribution box modules, the cable distribution box modules are connected in series, the output end of the at least one transformer substation module is connected with a bus, and the cable distribution box modules are connected with the bus. Each cable distribution box module comprises a fault signal simulation unit, a terminal unit and a controllable switch, the fault signal simulation unit is used for outputting a fault signal of a set type, the terminal unit is used for acquiring an input signal and an output signal of the cable distribution box module, performing fault diagnosis on a simulation power distribution network segment to which the cable distribution box module belongs based on the input signal and the output signal, and outputting a switch control signal when it is determined that a fault exists in the corresponding simulation power distribution network section; and the controllable switch is connected with the terminal unit and is used for responding to the switch control signal to switch the on-off state of the corresponding simulation power distribution network segment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of power equipment, and in particular to a distribution network automation simulation system and a distribution network fault simulation method. Background technique [0002] With the application of distribution network automation technology in the distribution network, the number of terminal equipment has also increased sharply. Considering the lack of skills and the small number of existing distribution network automation operation and maintenance personnel, there is an urgent need for distribution network automation station equipment Various types of fault finding and handling training. [0003] At present, a complete set of circuit breaker cabinets is mostly used as a training tool to simulate various faults for troubleshooting training for operation and maintenance personnel. The complete set of circuit breaker cabinets is not only expensive, but also the complete set of circu...

AI Technical Summary

Problems solved by technology

The complete set of circuit breaker cabinets is not only costly, but also the complete set of circuit breaker cabinets is large in size and occupies a large area, which requires high training venues. Therefore, the use of complete sets of circuit breaker cabinets greatly limits its applicable training scope
