Electric charge calculation method considering harmonic characteristics of high-speed rail

The invention belongs to the field of electric charge calculation of electrified railways, and particularly relates to an electric charge calculation method considering harmonic characteristics of a high-speed rail. Comprising the following steps: S1, analyzing high-speed rail harmonic characteristics based on high-speed rail actually measured harmonic data; s2, calculating harmonic impedance of a power supply system side and a high-speed rail user side based on high-speed rail harmonic characteristics; s3, dividing harmonic responsibilities of a system side and a high-speed rail side based on high-speed rail harmonic impedance; and S4, establishing an electric charge calculation model based on the divided harmonic responsibilities. According to the method, harmonic responsibilities of a power supply system side and a high-speed rail user side can be reasonably divided, and fine and reasonable promotion of electric charge metering work of an electric power department and a railway department is facilitated. 本
