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.

Abstract

The invention discloses a feeder automation detection and simulation system. The feeder automation detection and simulation system comprises a feeder automation control unit, fault simulators, a plurality of GPS modules and a plurality of simulation switches. The feeder automation control unit is used for obtaining a protection motion scheme of a circuit where the feeder automation control unit is located according to sampling data. The fault simulators are respectively connected with the feeder automation control unit and used for simulating different types of transformer substation faults. The GPS modules are correspondingly connected with the fault simulators one to one and used for conducting time synchronization on the GPS modules and a satellite clock so as to ensure that all the fault simulators simultaneously simulate faults. The simulation switches are connected in series to form a network and send position signals to the fault simulators. The feeder automation detection and simulation system can simulate various types of faults and is convenient to carry and easy to install and operate.

Description

technical field [0001] The invention relates to the technical field of power testing, in particular to a feeder automatic detection simulation system. 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 Facing the existing problems in the distribution network, such as outdated equipment, low power supply level, low automation level, and backward management, it is necessary to carry out the project under realistic conditions.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 reduce the labor intensity of operators, reduce per...
