Description

Technical Field

[0001] This application relates to the technical field of ultra-high-speed maglev traction control, and particularly to a method, device, equipment, and storage medium for optimizing traction power supply efficiency. Background Art

[0002] Under the background of the current development of ultra-high-speed maglev trains, the operating speed of ultra-high-speed maglev trains can exceed 1000 km / h, which has received extensive attention at home and abroad.

[0003] When an ultra-high-speed maglev train runs on the track, the ground traction converter equipment supplies power to the stator section of the linear motor and generates a traveling magnetic field, which drives the train to run. Figure 1 The shown traction control system adjusts the output voltage of the converter according to the current operating state of the train. The switch controller controls the opening and closing actions of the substation switch stations along the line according to the current position of the train combined with the step-changing strategy, and controls the frequency, phase, and amplitude of the current output to the stator section of the linear motor, so that the train runs according to the planned trajectory.

[0004] When a vehicle runs on the line, a converter is required to supply power to drive the vehicle. The line power supply methods include single-end power supply method and double-end power supply method. The single-end power supply method has a relatively simple connection and requires less energy from the substation. However, due to the capacity limitation of the single-end substation, the vehicle cannot reach a very high operating speed only by the single-end power supply method. Therefore, in ultra-high-speed maglev transportation, the double-end power supply method is usually adopted, that is, two substations at both ends of the line are used to supply power to the line in parallel at the same time.

[0005] In double-end power supply, the commonly used current output method is that the double-end converters output the same current to the stator section of the linear motor. This control method is relatively simple and easy to implement, but the overall traction power supply efficiency of the system is relatively low. Summary of the Invention

[0044] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0045] In the process of implementing the present application, the inventors found that when a vehicle runs on a line, a converter is required to supply power to drive the vehicle to run. The line power supply methods include a single-end power supply method and a double-end power supply method. The single-end power supply method has a relatively simple connection and requires less energy supply from a substation. However, limited by the capacity of the single-end substation, the vehicle cannot reach a very high running speed only by the single-end power supply method. Therefore, in ultra-high-speed maglev transportation, the double-end power supply method is usually adopted, that is, two substations at both ends of the line are used to supply power to the line in parallel. In the double-end power supply, the commonly used current output method is that the double-end converters output the same current to the stator section of the linear motor. This control method is relatively simple and easy to implement, but the overall traction power supply efficiency of the system is relatively low.

[0046] In view of the above problems, the embodiments of the present application provide a method, device, equipment, and storage medium for optimizing the traction power supply efficiency. The method obtains the position of the vehicle from the positioning and speed measurement system; determines the cable resistance and inductance parameters of the double-end converter according to the position; detects the working mode of the current double-end converter based on the cable resistance and inductance parameters; and allocates the target current value according to the working mode. The method provided by the present application allocates the target current value according to the position of the vehicle in combination with the cable resistance and inductance parameters of the double-end converter, realizes the optimization of the efficiency of the traction power supply system, and improves the overall traction power supply efficiency.

[0047] When an ultra-high-speed maglev vehicle runs on a line, the double-end converters are connected in parallel to supply power to the motor stator module. During the running of the vehicle, after the traction control system is synchronized with the operation control system and the positioning and speed measurement, the positioning and speed measurement system respectively sends the position and speed information of the vehicle to the traction control system and the operation control system. The operation control system protects the vehicle in combination with the operation curve and the protection curve, and issues corresponding control instructions to the traction control system. After receiving the data information of the positioning and speed measurement system and the operation control system, the traction control system synchronizes the data of the double-end controller and issues the traction control instructions to drive the vehicle to run according to the target operation curve.

[0048] After the vehicle starts to run, the method for optimizing the traction power supply efficiency provided by this embodiment controls the output of the double-end converter according to the real-time operation data.

[0049] See Figure 2, the implementation process of the traction power supply efficiency optimization method provided in this embodiment is as follows:

[0050] 201. Obtain the position of the vehicle system-wide.

[0051] For example, obtain the position and speed information of the vehicle from the positioning and speed measurement system.

[0052] In specific implementation, the traction control system can obtain the position and speed information of the vehicle from the positioning and speed measurement system.

[0053] 202. Determine the cable resistance and inductance parameters of the dual-end converter according to the position.

[0054] In specific implementation, the cable resistance and inductance parameters of the dual-end converter will be determined by combining the position and the power supply cable parameters of the dual-end converter.

[0055] For example, the motor controller combines the current position of the vehicle to calculate the power supply cable parameters of the dual-end converter to obtain the cable resistance and inductance parameters of the dual-end converter.

[0056] 203. Detect the working mode of the current dual-end converter based on the cable resistance and inductance parameters.

[0057] In specific implementation, the state of the dual-end converter will be detected based on the cable resistance and inductance parameters to determine the working mode of the current dual-end converter, and at the same time obtain the maximum output voltage and maximum output current.

[0058] 204. Allocate the target current value according to the working mode.

[0059] The implementation process of this step is as follows: Determine the power supply method according to the working mode. If the power supply method is single-end power supply, the proximal converter of the dual-end converter outputs the target current value, and the distal converter does not output current. If the power supply method is dual-end power supply, the target current value is allocated according to the position, the parameters of the dual-end converter, and the traction power supply cable parameters.

[0060] Among them, the power supply method is single-end power supply or dual-power supply.

[0061] In addition, when the power supply method is single-end power supply, the distal converter will also block the IGBT (Insulate-Gate Bipolar Transistor) pulses.

[0062] For example, perform data calculation and analysis on the current converter power supply mode, and adopt single-end / dual-end power supply. If single-end power supply is adopted, the proximal converter outputs the target current value, the distal converter blocks the IGBT pulses and does not output current. If dual-end power supply is adopted, the target current value is allocated according to the current position of the vehicle, the converter parameters, the traction power supply cable parameters, etc.

[0063] After performing step 204, that is, after the optimization algorithm ends, the allocated target current value will also be output to the current closed-loop control.

[0064] In addition, before performing Figure 1 the method shown, the following will also be done:

[0065] Determine that the communication signals of each system controller in the vehicle are connected and the communication signals are correct.

[0066] Through the control function test, determine that each system controller responds normally to the communication control signal.

[0067] Determine that each system is powered on and the power-on operation is normal.

[0068] The traction power supply efficiency optimization method provided in this embodiment is a traction power supply efficiency optimization method that takes into account the position change of the vehicle, and is mainly applied to the traction control of the vehicle under the double-end power supply architecture. After the vehicle starts running, the traction control system calculates the traction power supply efficiency according to the current vehicle position, traction power supply cable parameters, converter capacity, etc., and distributes the current output of the double-end converter according to the above parameters, and realizes the optimization of the power supply efficiency of the traction power supply system under the condition of meeting the system operation conditions.

[0069] The traction power supply efficiency optimization method provided in this embodiment can be tested through the following test process.

[0070] 1. Connect the communication signals of each system controller. Connect the communication interfaces between the controllers of each system and the communication interfaces of the controller and the interface module. After the connection is completed, check the communication. After checking and testing that the communication protocol is correct, the subsequent tests can be carried out.

[0071] 2. Control function test of each system. After checking that the communication signals are correct, perform the control function test, observe whether each controller can perform the test according to the designed process, whether it responds normally to the communication control signal, and feedback the controller status information.

[0072] 3. Power on the power equipment of each system. Only when the power-on operation is checked to be normal and there is no fault can the test continue.

[0073] 4. Start the system joint debugging test. According to the test process, each system controller issues commands and feedbacks its own operating status, and each device receives the control command and executes the corresponding actions to perform the target test.

[0074] 5. During the test, execute the traction power supply efficiency optimization method provided in this embodiment, that is, execute the traction power supply efficiency optimization method that takes into account the position change of the vehicle through the traction control system.

If double-end power supply is used, distribute the current of the double-current converter.

[0076] 6. Determine the test results. After the test is completed, determine the operation data of each controller and the simulation system to see if the test is successful.

[0077] 7. After the test is completed, collect and store the test data for subsequent data analysis. Power off the system.
