In order to make full use of the original transmission corridor, and to improve grid transmission capacity, a new idea for increasing the power transmission capacity which is based on the voltage source converter (VSC) technology is put forward. It is studied to reform the operation mode of the original transmission system into the transmission mode of VSC triple-pole DC or the long cycle AC square wave transmission mode. Technical solutions for capacity increase and reform are proposed for different applications, and the operation mode and technical characteristics are also introduced in detail. The proposed technical solutions expand ideas for increasing the power transmission capacity of the urban power grid, and also provide reference for the planning, construction and operation of the urban power grid.
