Embodiment Construction
[0023] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention will be further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention, and are not intended to limit the present invention.
[0024] In one embodiment, as figure 1 As shown, it is a flow chart of a method for controlling the installed capacity of a traction transformer in an embodiment, including steps:
[0025] S101, acquiring the response parameters of the traction transformer under the set installation capacity;
[0026] Among them, the maximum overload current of the traction transformer under the set installation capacity is obtained, that is, the installation capacity of the traction transformer is adjusted to the set installation capacity, and the response parameters during the operation of the t...

The invention provides a method and device for controlling the installed capacity of a traction transformer. By judging the response parameters of the traction transformer under the set installed capacity, the set installed capacity is corrected according to the judgment result until the response parameter is greater than the second preset limit value and is less than the first preset limit value, the set installation capacity under this condition is obtained, and the set installation capacity is determined as the final installation capacity of the traction transformer. Based on this, the installation capacity of the traction transformer can meet the load requirements under the tight running conditions of the train, and at the same time reduce the installation capacity of the traction transformer and the surplus space of the operation life, so that the installation capacity of the traction transformer tends to be reasonable, and the cost of the traction power supply system can be reduced. operating costs.
Description
technical field [0001] The invention relates to the technical field of rail transit power supply control, in particular to a method and device for controlling the installed capacity of a traction transformer. Background technique [0002] The traction transformer is a special power transformer that provides traction power for electric locomotives or EMUs, and its capacity must meet the load requirements of the train under tight operating conditions. Generally, the traction transformer capacity is designed to meet the power supply capacity requirements of the maximum load. However, because the traction load has the characteristics of large short-term load and small daily average load, the traction transformer in actual operation is in the under-load operation state most of the time, and the average load rate of the traction transformer is low, resulting in the installation capacity and operating life of the traction transformer. The large surplus leads to an increase in the ...
