As the grid voltage of the V/v power supply system for high-speed railway is distorted, the detection method for harmonic and negative sequence current is complex, and there are errors in the detection result. A method is proposed in order to solve these issues, which is capable of carrying out fast and accurately comprehensive compensation for grid current without the PLL circuit. During the detection process, a group of sine and cosine function with arbitrary initial phase angle is needed, the grid fundamental positive sequence voltage is extracted to participate into the detection of fundamental active power component to obtain the command signal. The calculation process is fast and simple and not affected by the distorted grid voltage. The correctness and feasibility of this method is verified by the result of simulation
