Description

Technical field

[0001] The invention belongs to the field of virtual reality technology application and substation simulation training, and in particular relates to a demonstration simulation display method and device for safety measures of substation current loop operations. Background technique

[0002] In conventional substations, the current circuit is one of the most important secondary circuits for relay protection. If there is an accidental touch or incorrect wiring during the operation of the current loop, it is very easy to cause the protection to malfunction, thereby affecting the stable operation of the power grid or causing load loss. For example, in 2016 alone, three incidents of 500kV protection malfunctions occurred within the scope of the Southern Power Grid in the case of insufficient current loop safety measures due to accidental touch or miswiring of the current loop operation. Therefore, studying the work safety measures of the current loop and developing its...
