The invention relates to a power grid interlink system of offshore oil platforms. In the system, a plurality of offshore platform power stations on a plurality of offshore oil drilling platforms distributed in a sea area are connected through submarine cables so as to form a small-sized grid-connected power system. The submarine cables are optical fiber cables and embedded below 0.5-2.5m of a sea bed. The small-sized power system comprises a concentrated information management layer arranged in a power station scheduling management center, and data acquisition servers, a power station machine set control system, a video session device and corresponding network equipment respectively arranged on the plurality of offshore platform power stations. Through power grid interlink, the invention ensures that all the platforms can be mutually supplied with power so as to enhance the capability on resisting accidents, improve the power supply reliability of all the power stations, reduce the quantity of spare machine sets, improve the utilization ratio of idle assets and economic benefits, save the investment as well as the operation and maintenance cost, and effectively reduce the development and investment cost on new oil and gas fields and the energy source consumption.
