Substation training device based on PLC (programmable logic controller)

Abstract

The invention relates to a substation training device based on a PLC (programmable logic controller). The substation training device comprises a base, an operating display screen, an alternating current air switch, an alternating current contactor, an intermediate relay, the PLC, a grounding fault setting device, a wiring terminal block, PLC signal input devices and PLC signal output devices, wherein the base is provided with a power plug, and the operating display screen comprises a box shell, a simulation circuit board, a warning device, an isolation switch operating rocking rod, a displayer I, a displayer II and a plurality of voltmeters. The substation training device has the advantages that through controlling the operating display screen by the PLC, one-time analogue simulation training of a substation is realized, the training problem of electricity utilization operating personnel is solved, the educational and training quality of trainees is fast promoted, the acceptability of electricians for network access operation is greatly improved, the operation is visual and vivid, the trainees can easily grasp the learned key points, a notable effect is produced, and the problem that the actual operation is very complex and is difficult to grasp is solved.

Description

technical field [0001] The invention relates to a PLC-based substation training device. Background technique [0002] At present, power supply and distribution equipment of 35kV and below for power grids and power users is relatively common, and the actual operation and management level of equipment operators is uneven, especially when a single-phase ground fault occurs on the equipment, lack of experience in searching and improper operation steps are easy to occur Misoperation and comprehensive loss of voltage and large-scale power outages occur. [0003] At the same time, how to quickly improve the quality of trainees' education and training, and how to greatly improve the qualification rate of electricians who work on the network have become a topic that we need to solve urgently. The original teaching mode is that classroom teaching is carried out separately from the actual operation of equipment. Students generally report that classroom teaching is boring and has limit...

AI Technical Summary

Problems solved by technology

The original teaching mode is that classroom teaching is carried out separately from the actual operation of equipment. Students generally report that classroom teaching is boring and has limited results, while actual operation is more complicated and difficult to master the whole process of operation.
