The invention provides an intelligent transformer station virtual reality simulation training system based on hardware-in-loop. The training system comprises a transformer station primary system, a signal conversion port and an intelligent transformer station secondary device. The transformer station primary system comprises a transformer station three-dimensional simulation system, a teacher machine and a leaner machine, which are connected with each other through the Ethernet. The intelligent transformer station secondary device comprises a protection measurement and control device and a background monitoring system, which are connected with each other through the MMS network. Normal power grid faults are set on the teacher machine or the learner machine; the transformer station three-dimensional simulation system calculates current, voltage and frequency signals that the power grid should have when faults occur according to fault conditions; the protection measurement and control device carries out protection actions on the fault places of the power grid and forms signals; the background monitoring system carries out background detection; and the signal conversion port carries out format conversion on information generated by the three-dimensional simulation system, sends the obtained information to the protection measurement device, carries out format conversion on information generated by the protection measurement and control device and sends the obtained information to the transformer station three-dimensional simulation system.

Description

technical field [0001] The invention relates to an intelligent substation technology, in particular to a hardware-in-the-loop intelligent substation virtual reality simulation training system. Background technique [0002] With the rapid development of smart grid technology, technologies such as smart high-voltage electrical, optical fiber Ethernet and IEC61850 standard communication have been gradually promoted and applied in smart substations. On-site operation and maintenance personnel lack understanding of new technologies and new equipment for smart grids, and most operation and maintenance personnel have not mastered the operation and maintenance technologies of smart substations. There is an urgent need for comprehensive smart substation training for substation operation and maintenance personnel. The existing training system for traditional substations is far from meeting the requirements of the development of smart substations. It is necessary to develop a simulatio...

AI Technical Summary

Problems solved by technology

[0005] At present, for the training of smart substations, there is an all-digital simulation system available, but although this system can simulate the normal operation and operation process of substations, because it is a full-digital simulation without real equipment, it cannot achieve the training of maintenance and repair skills. Purpose

Another full physical simulation system needs to use physical equipment to simulate the actual power grid primary system. The wiring method is not flexible, the fault cannot be set arbitrarily, and the primary equipment construction investment is large and maintenance is difficult.

However, the functions of the hybrid simulation training system for smart substations are more complicated. Due to the different communication interfaces between the primary simulation software of the substation and the intelligent secondary protection equipment, the substation simulation training system based on the combination of software and hardware has not achieved good development.
