Abstract

The present disclosure provides a fracturing system comprising fracturing equipment. The fracturing equipment comprises a power supply platform, a gas turbine engine, one or more rectifiers, and a power system comprising at least one of the following: a generator, an energy storage, and an electricity supplier. At least two of the gas turbine engine, the power system, and the one or more rectifiers are arranged on the power supply platform. A first end of the power system is connected to the gas turbine engine. A second end of the power system is connected to the one or more rectifiers. The power system is configured to output a voltage to the one or more rectifiers directly without passing through a rectifier transformer.
