Frequency conversion power transmission system

A frequency conversion power transmission system, comprising:

• a new energy power generation base, a first isolation device, a second isolation device, an alternating current-alternating current (AC-AC) frequency conversion device and a power transmission cable;
• wherein
• the new energy power generation base comprises power generation equipment that uses new energy, comprising at least one of wind energy, water power or solar energy, for power generation;
• and the new energy power generation base is configured to supply electrical energy to an AC power grid, and operate at a constant voltage and a constant or variable frequency according to environmental conditions comprising at least one of weather, an environment or a distance;
• the first isolation device is connected to the new energy power generation base;
• the second isolation device is connected to the AC power grid;
• an input terminal of the AC-AC frequency conversion device is connected to the first isolation device, an output terminal of the AC-AC frequency conversion device is connected to the second isolation device, and the AC-AC frequency conversion device is configured to convert a three-phase voltage at a first frequency of the new energy power generation base into a three-phase voltage at a second frequency, wherein the first frequency is selected according to the environmental conditions and lower than the second frequency, and the second frequency is an industrial frequency and determined according to a power transmission requirement;
• and
• the power transmission cable is configured to connect the new energy power generation base and the first isolation device.
