Problems solved by technology

However, the excitation current is fixed when the excitation is faulty, and the electricity generated is only enough to slowly drag the locomotive back to the locomotive depot for maintenance, and the driver's handle cannot be pulled to a high position, which may easily lead to overvoltage

Abstract

The invention discloses a thermal redundant excitation control system and method for a generator. The thermal redundant excitation control system for the generator comprises a first DSP control detector, a second DSP control detector and a relay. During normal excitation, the first DSP control detector is connected with the excitation winding of the generator through the relay to control the excitation of the generator and monitor the signal output by the generator. When the first DSP control detector fails, the first DSP control detector automatically switches the relay, and the second DSP control detector is connected with the excitation winding of the generator to control the excitation of the generator and monitor the signal output by the generator.

Description

technical field [0001] The invention relates to the field of power supply control, in particular to a thermal redundant excitation control system and method for a generator of a diesel locomotive. Background technique [0002] The diesel locomotive uses the internal combustion engine as the motive power and drives the wheels through the transmission. Most of the internal combustion engines used in my country's railways are diesel engines. The diesel is burned in the cylinder to convert thermal energy into mechanical energy, but it is not used to directly drive the moving wheels, but is converted into mechanical energy suitable for the traction characteristics of the locomotive through the electric transmission device. The moving wheel of the locomotive is driven to rotate on the track through the running part. [0003] The generator in the electric drive of a diesel locomotive needs to be controlled by a microcomputer for excitation. figure 1 A general generator microcomput...
