Looped network outdoor station fault simulator and fault simulation method thereof

Abstract

The invention discloses a looped network outdoor station fault simulator which comprises a feeder automation control unit, a power distribution terminal connected with the feeder automation control unit, a data bus connected with the feeder automation control unit, an analog-digital conversion unit, a power module, a sampling unit and an analog switch connected with the feeder automation control unit. The analog-digital conversion unit and the power module are connected with the data bus, the sampling unit is respectively connected with the power distribution terminal and the analog-digital conversion unit, the power module is used for providing electric energy for the whole simulator, and the sampling unit is used for sampling currents generated by the power distribution terminal. The analog switch sends position signals to the feeder automation control unit, and the feeder automation control unit determines to power off or power on the output of the fault currents according to the position signals of the analog switch. The invention further discloses a looped network outdoor station fault simulation method. According to the looped network outdoor station fault simulator and the simulation method, the fault of a 10 KV feeder can be simulated, the fault currents of can be generated, the simulator is convenient to carry, wiring is convenient and safe, and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of electric power testing, in particular to a ring network outdoor station fault simulator and a fault simulation method thereof. Background technique [0002] With the continuous development of the economy and the improvement of people's lives, users' requirements for the quality of power supply continue to increase. Facing the existing problems in the distribution network, such as outdated equipment, low power supply level, low automation level, and backward management, it is necessary to carry out the project under realistic conditions. Distribution network automation is a top priority. Realizing distribution network automation is the most effective means for distribution network system to improve power supply reliability. It can not only reduce the scope of power outages, shorten the time of power outages, improve the quality of power supply, and provide users with higher quality services, but also redu...

Problems solved by technology

[0008] Since the actual line has been put into operation and the equipment is in working condition, if the FA logic is verified in the case of a power outage, it will cause relatively large losses to the user's power consumption. If the FA logic is tested without a power failure, it will encounter problems in all aspects. There are many difficulties, such as fault simulation mode, switch action status, fault handling process record, etc.
