Distribution network terminal inspection fault simulation method and system

Abstract

The invention discloses a distribution network terminal inspection fault simulation method. The method comprises the following steps that S1, a communication network and a remote control unit are established, and related components are set to build a set of complete communication network; S2, a voltage and current source function unit is established for performing circuit breaker position detection and system wiring topology analysis; S3, a secondary circuit operation and maintenance function module is established; S4, a circuit breaker cabinet electrical test function module is established; S5, a primary cable electrical test function module is established; and S6, in a system operation process, voltage electrical analog quantity information and switch element position indication information of different systems in a normal fault-free working condition and an abnormal fault condition are acquired in different working states through fault simulation. By implementing the method, multiple faults and recovery functions are truly simulated, actual conditions are met, and interactive experience is true; and the method is low in cost and high in efficiency.

Description

technical field [0001] The invention belongs to the field of electric power applications, and relates to a method and system for simulating faults in inspections of distribution network terminals. Background technique [0002] At present, my country's distribution network terminal troubleshooting training mainly adopts the method of combining theory with practical demonstration / operation. There are two main forms of training. One is to erect several overhead lines and cable lines, configure ring network cabinets and box transformers to build grids, and train It is relatively complete and has a strong sense of reality, but the construction cost is high and the demand for the site is large. At the same time, only a group of personnel can be trained, the training period is long and the efficiency is low; the other is pure software simulation using virtual reality technology. The construction cost of the formal training system is low, the station expansion is flexible, and multi-s...
