The invention discloses an LCL compensation topology for a smart substation rail guidance vehicle electricity pickup, which comprises a voltage source Uin, a compensation inductor L1, a coil self-inductor L2, a compensation capacitor C and a load resistor RL, the first end of the voltage source Uin is connected with the first end of the compensation inductor L1, the second end of the voltage source Uin is connected with the first end of the compensation capacitor C and the first end of the load resistor RL, and the second end of the compensation capacitor C is connected with the second end of the load resistor RL. The second end of the compensation inductor L1 is connected with the second end of the compensation capacitor C and the first end of the coil self-inductor L2, and the second end of the coil self-inductor L2 is connected with the second end of the load resistor RL. The constant voltage characteristic is realized by changing the parameters of the compensation topology, and the stability of the system is improved; moreover, the voltage gain can be changed by adjusting the parameters of the compensation device, the adjustability of the output power is realized, and the problems of unstable output voltage and low transmission efficiency are solved, so that the influence of load change on the output power and efficiency is reduced.
