Background technique

The UHV power grid is the transmission system with the highest operating voltage in the world today. At present, the Soviet Union and Japan have built transmission lines. The State Grid Electric Power Research Institute has conducted years of research on the key technologies of UHV transmission projects, based on fully absorbing, digesting and referring to domestic and foreign UHV scientific research results and foreign UHV operation experience, as well as summarizing my country's 500kV and 750kV operation experience In addition, research on overvoltage and insulation coordination of 1000kV systems suitable for China's national conditions has been carried out.

Since the overvoltage and insulation coordination of the 1000kV AC UHV grid have many characteristics different from those of 500kV and 750kV, especially the content of the overvoltage and insulation coordination of the UHV transmission system contains a lot of theoretical knowledge and is conceptually strong. Operators often Requires excellent training. However, this kind of operator training cannot be carried out at any time, and has great limitations. Some operations cannot be repeated in the actual operation process, such as some unpredictable operations (the occurrence of lightning, various accidents, etc.), the phenomena and results cannot be shown to the user at any time; and the actual training has great restrictions on the user's operation, and some of them will paralyze the system or even damage the system and cause serious damage to the system once the operation is wrong. Economic losses, and even serious social consequences, so users can only receive partial training, and cannot receive complete training at any time.

In the special environment of UHV transmission system, it is necessary to invent a training system, especially the training system of overvoltage and insulation coordination technology to overcome the above problems.
