Line fault test method based on asymmetry

The invention discloses a line fault test method based on asymmetry, and belongs to the field of power distribution network tests. The method comprises the following steps: S1, constructing a power distribution asymmetric test field; S2, when power is not on, setting a lumped parameter model; S3, simulating various asymmetry degrees of the real power distribution network by changing parameters inthe lumped parameter model; S4, simulating a load carried by a real distribution line by changing parameters in the lumped parameter model; S5, simulating a plurality of wiring modes of the distribution line by adjusting the asymmetric test field; S6, supplying power to the power distribution asymmetric test field, raising the voltage to a rated voltage with consistent voltage class of the power distribution network, and simulating various faults of the line of the power distribution network under a certain degree of asymmetry; and S7, transmitting the test data to a computer analysis unit forstorage and analysis.
