The invention discloses a method for determining a loop chain comprehensive grid structure scheme of a receiving-end power grid. The method comprises the following steps: determining key transformer substations in the receiving-end power grid; determining a partitioning scheme according to power grid parameter information, and distributing the key transformer substations to different partitions; determining contact channels between the partitions; and determining a construction scheme of the grid structure of the receiving-end power grid according to the partitioning scheme and the contact channels. According to the invention, the partitioning scheme is determined according to the power grid parameter information; the key transformer substations are distributed to the different partitions,so that the density of the receiving-end power grid is relieved and the electrical distance between the transformer substations is increased; and when the electrical distance between the receiving-end transformer substations (converter stations) is increased, the relative integrity of the power grid structure is kept, and the safety and stability level of the system is improved. The invention further provides a system and equipment for determining the loop chain comprehensive grid structure scheme of the receiving-end power grid, and a computer readable storage medium, which have the above beneficial effects.
