A control method, device, medium and equipment for output power of dual internal combustion units

Abstract

The present application discloses a method, device, medium and equipment for controlling the output power of a dual internal-combustion unit. The method includes: judging whether the target output power required by the target dual internal-combustion unit is greater than the rated output power of a single internal-combustion unit in the target dual internal-combustion unit ; If so, then run the first internal combustion group and the second internal combustion group; the three-phase alternating current output by the first internal combustion group and the second internal combustion group is converted into the first direct current and the second direct current; the voltage of the first direct current and the second direct current Adjust the value to be consistent; when the first internal combustion set and the second internal combustion set realize DC grid connection, adjust the three-phase alternating current output by the first internal combustion set and the second internal combustion set, so that the first internal combustion set and the second internal combustion set The sum of the output power output is the target power. It can be seen that through this method, the respective output powers of the first internal combustion unit and the second internal combustion unit of the dual internal combustion units can be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method, device, medium and equipment for controlling output power of dual internal combustion units. Background technique [0002] In the field of rail transit technology, due to the large output power range of the dual internal combustion unit, it has been applied in practice. If the target output power of the dual internal combustion units is greater than the rated output power of a single internal combustion unit of the dual internal combustion units, the two internal combustion units of the dual internal combustion units must operate simultaneously to make the dual internal combustion units output the target power. However, since the output of the first internal combustion set and the second internal combustion set in the dual internal combustion sets is a three-phase alternating current, only the power frequency, voltage value, phase sequence and Only when the phases...

AI Technical Summary

Problems solved by technology

However, when the first internal combustion unit and the second internal combustion unit are connected to the AC grid, the respective output powers of the first internal combustion unit and the second internal combustion unit cannot be flexibly adjusted, and only the first internal combustion unit and the second internal combustion unit Always run synchronously to make the dual internal combustion units output the target power, which leads to a relatively single operation mode for the output power of the dual internal combustion units
