[0054] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0055] Before the embodiments of the present application are introduced, it should be noted that, in order to respond to the development direction of green and low carbon, realize energy saving and consumption reduction, the electrified railway traction power supply system adopts a flexible traction power supply device based on power electronic technology to form a new traction power supply system. The flexible traction power supply device is mainly composed of a high-voltage switch, an isolation transformer, a converter, an energy storage device and a control and protection unit. The flexible traction power supply device is configured in a substation, an AT station and a partition station. The regenerative braking capacity is utilized according to the traction load state, and the introduction of new energy such as photovoltaic and wind energy is realized in real time.

[0056] The specific form of the flexible traction power supply device is that the converter group is installed in the converter bin, the energy storage battery cluster is installed in the energy storage battery bin, and the controller is installed in the control room. Each component will generate heat when working, especially the converter and the battery. The battery cluster adopts a closed liquid cooling method for heat dissipation, the converter group adopts a liquid cooling and air conditioning refrigeration method for heat dissipation, and the controller adopts air conditioning for heat dissipation. In order to prevent the equipment from being damaged in extremely cold environments, the equipment needs to be insulated. The converter group and the battery cluster are insulated by liquid cooling circulation, and the control element is insulated by air conditioning heating. The temperature control of the entire flexible traction power supply device is a multi-objective and energy control system.

[0057] At present, the fan, the circulating pump and the water replenishment pump of the liquid cooling system operate in a fixed frequency mode. The circulating pump operates in a fixed frequency mode. The start and stop of the fan are grouped and turned on and off by detecting the pipeline temperature. The water replenishment pump is started and stopped according to the water pressure. In the actual operation process, no matter what working mode, the working mode of the liquid cooling system is the same, which causes inaccurate temperature control, unstable pipeline pressure, unstable liquid cooling circulation flow, slow real-time response, poor dynamic performance, high energy consumption, high energy consumption cost and great influence on the energy saving effect of the entire system. Based on the above background, the present application provides a humidity control method, in particular, an intelligent control method for the working temperature of a flexible traction power supply device.

[0069] The battery compartment liquid cooling control cabinet 4 includes a variable frequency circulating pump 41, a distributed controller 42, and a stop valve 43. The variable frequency circulating pump 41 includes two pumps and a variable frequency controller VFD1, which is used to give a frequency and power through the distributed controller, to control the operation of the circulating pump by variable frequency, to achieve the control of water flow and water pressure.

[0071] In S120, a temperature control strategy corresponding to each device compartment is determined according to temperature information corresponding to each device compartment.

[0072] In an optional embodiment, the temperature information corresponding to each device compartment can be input into a pre-trained strategy determination model to obtain the temperature control strategy corresponding to the corresponding device compartment.

[0073] In another optional embodiment, the temperature control strategy corresponding to each device compartment can be determined according to the temperature information corresponding to each device compartment and the current working mode of the flexible traction power supply device.

[0074] For example, in the case where the current working mode is the working mode, the temperature control strategy corresponding to each device compartment is determined according to the temperature information corresponding to each device compartment, and the specific implementation is introduced in the following embodiments. In the case where the current working mode is the non-working mode, the preset temperature control strategy corresponding to each device compartment is used as the corresponding temperature control strategy.

[0075] In S130, for any device compartment, temperature control is performed on the device compartment based on the temperature control strategy corresponding to the device compartment.

[0076] In the above temperature control method, the temperature information corresponding to different device compartments in the flexible traction power supply device is obtained; the temperature control strategy corresponding to each device compartment is determined according to the temperature information corresponding to each device compartment; and for any device compartment, temperature control is performed on the device compartment based on the temperature control strategy corresponding to the device compartment. The temperature control method realizes temperature compartment control, makes the working temperature control more intelligent, and further enables the working components to reliably operate at a normal working temperature, thereby improving the operation efficiency and saving energy.

[0077] On the basis of the technical solutions of the above embodiments, the present application further provides an optional embodiment. In the optional embodiment, the device compartment includes a converter compartment, and the process of determining the temperature control strategy corresponding to each device compartment according to the temperature information corresponding to each device compartment is refined.

[0078] See Figure 2 The temperature control strategy determination steps shown include:

[0079] S210, input the temperature information corresponding to the converter compartment and the temperature information corresponding to the liquid chiller compartment into the pre-trained temperature trend estimation model to obtain the first temperature trend, and determine the temperature control strategy corresponding to the converter compartment based on the first temperature trend.

[0080] In one alternative implementation, temperature control strategies corresponding to different temperature trends can be predetermined, and the temperature control strategy corresponding to the first temperature trend can be used as the temperature control strategy corresponding to the converter compartment.

[0081] In another alternative implementation, if the first temperature trend indicates a decrease in temperature, a temperature control strategy corresponding to the converter compartment can be determined based on the ambient temperature of the converter compartment; if the first temperature trend indicates an increase in temperature, a temperature control strategy corresponding to the converter compartment can be determined based on the ambient temperature of the converter compartment and the inlet pipe temperature of the converter compartment.

[0082] For example, when the ambient temperature of the converter compartment is less than a first temperature threshold, a first strategy is determined as the temperature control strategy corresponding to the converter compartment; the first strategy is heating by air conditioning. When the ambient temperature of the converter compartment is not less than the first temperature threshold, a second strategy is determined as the temperature control strategy corresponding to the converter compartment; the second strategy is heating by pipe heaters.

[0083] For example, when the first temperature trend indicates an increase in temperature and the ambient temperature of the converter compartment is greater than the second temperature threshold, a third strategy is determined as the temperature control strategy corresponding to the converter compartment; the third strategy is to use air conditioning for cooling. When the first temperature trend indicates an increase in temperature and the ambient temperature of the converter compartment is not greater than the second temperature threshold, a fourth strategy is determined as the temperature control strategy corresponding to the converter compartment; the fourth strategy is to control the liquid cooling fan for cooling based on the temperature of the converter inlet pipe, or to control the frequency of the converter circulating pump for cooling based on the temperature of the converter inlet pipe.

[0084] In another alternative embodiment, the temperature control strategy corresponding to the converter compartment can be as follows: the subsequent converter compartment operating temperature control strategy S1.

[0085] In the above embodiments, a temperature control strategy corresponding to the converter compartment is determined based on the first temperature trend, so that the temperature control strategy can better match the temperature change represented by the first temperature trend, thereby making the temperature set based on the temperature control strategy more suitable for the working environment of the corresponding components.

[0086] On the basis of the technical solutions of the above embodiments, the application further provides an optional embodiment. In the optional embodiment, the device bin includes a battery bin, and correspondingly, the process of determining the temperature control strategy corresponding to the battery bin according to the temperature information of each device bin is refined.

[0087] Referring to Figure 3 The temperature control strategy determination step shown includes:

[0088] S310, input the temperature information corresponding to the battery bin and the temperature information corresponding to the liquid cooling unit bin into the pre-trained temperature trend estimation model to obtain a second temperature trend, and determine the temperature control strategy corresponding to the battery bin according to the second temperature trend.

[0089] In an optional implementation, the temperature control strategy corresponding to the second temperature trend can be determined in advance, and the temperature control strategy corresponding to the second temperature trend is taken as the temperature control strategy corresponding to the battery bin.

[0090] In an optional implementation, when the second temperature trend represents a temperature decrease, the temperature control strategy corresponding to the battery bin can be determined according to the ambient temperature of the battery bin; and when the second temperature trend represents a temperature increase, the temperature control strategy corresponding to the battery bin can be determined according to the ambient temperature of the battery bin and the water inlet pipe temperature of the battery bin.

[0091] For example, when the second temperature trend represents a temperature decrease and the water inlet pipe temperature of the battery bin is less than a third temperature threshold, a fifth strategy is determined as the temperature control strategy corresponding to the battery bin; the fifth strategy is heating through the pipe heater; when the second temperature trend represents a temperature decrease and the water inlet pipe temperature of the battery bin is not less than the third temperature threshold, a sixth strategy is determined as the temperature control strategy corresponding to the battery bin; the sixth strategy is heating through the liquid cooling unit.

[0092] For example, when the second temperature trend represents a temperature increase and the water inlet pipe temperature of the battery bin is greater than a fourth temperature threshold, a seventh strategy is determined as the temperature control strategy corresponding to the battery bin; the seventh strategy is cooling through the liquid cooling unit; when the second temperature trend represents a temperature increase and the water inlet pipe temperature of the battery bin is not greater than the fourth temperature threshold, an eighth strategy is determined as the temperature control strategy corresponding to the battery bin; the eighth strategy is cooling according to the battery temperature and the water outlet pipe temperature of the battery bin.

[0093] In still another optional implementation, the temperature control strategy corresponding to the battery bin can be the subsequent battery bin working temperature control strategy G1.

[0094] In the above embodiments, the temperature control strategy corresponding to the battery compartment is determined according to the second temperature trend, so that the temperature control strategy can be more matched with the temperature change represented by the second temperature trend, and thus the temperature set based on the temperature control strategy is more suitable for the working environment of the corresponding component.

[0095] Based on the technical solutions of the above embodiments, the present application further provides an optional embodiment. In the optional embodiment, the equipment compartment includes a controller compartment, and accordingly, the process of determining the temperature control strategy corresponding to the corresponding equipment compartment according to the temperature information corresponding to each equipment compartment is refined.

[0096] Referring to Figure 4 The temperature control strategy determination step includes:

[0097] S410, determining the temperature control strategy corresponding to the controller compartment according to the temperature information and humidity information corresponding to the controller compartment.

[0098] For example, in the case where the temperature corresponding to the controller compartment exceeds the preset high temperature threshold, the temperature control strategy corresponding to the controller compartment is determined to be air conditioning refrigeration; in the case where the temperature corresponding to the controller compartment is less than the preset low temperature threshold, the temperature control strategy corresponding to the controller compartment is determined to be air conditioning heating; and in the case where the humidity corresponding to the controller compartment exceeds the preset humidity threshold, the humidity control strategy corresponding to the controller compartment is determined to be air conditioning dehumidification.

[0099] In the above embodiments, the temperature control strategy corresponding to the controller compartment is determined according to the temperature information and humidity information corresponding to the controller compartment, so that the determination of the temperature control strategy of the controller compartment is more reasonable and efficient.

[0100] Based on the technical solutions of the above embodiments, the present application further provides an optional embodiment. In the optional embodiment, the equipment compartment includes a converter compartment, a battery compartment, and a controller compartment.
