Technical Field
The invention relates to the technical field of rail transit and transformer direct-current magnetic biasing, in particular to a rail transit train operation position retrieval method.
Background
The rail transit traction power supply is direct current, the traction direct current is large and can reach thousands of amperes, and as the rail transit rail is not completely insulated from the ground, a part of the traction direct current does not return to the negative pole of the power supply along a return rail, and the part of the traction direct current is called stray current. When the neutral point of the power grid transformer is directly grounded, stray current may flow into the neutral point of the power grid transformer, so that direct current magnetic bias occurs in the transformer, and normal operation of the transformer is affected.
In order to analyze and evaluate the influence of the track traffic stray current on the direct-current magnetic biasing of the power grid transformer, the correlation between the running position of the track traffic train and the direct-current magnetic biasing current of the transformer needs to be analyzed. The dc bias current of the transformer is typically monitored by mounting a sensor at the neutral point of the transformer.
