Description

Embodiments described herein relate generally to a regenerative electric energy estimation device and a brake plan planning device.

In the operation of the railway vehicle, the driver stops the train to the target position by operating the brake notch of the master controller provided in the cab. The command of the master controller is transmitted to the vehicle control device, and the vehicle control device calculates the braking force necessary for the train to decelerate and stop corresponding to the brake notch operation. The brake is composed of an electric brake and a friction brake. Basically, electric brakes are given priority, and friction brakes assist when the necessary braking force cannot be obtained. The electric brake is usually a system that operates (regenerates) and brakes as a generator by rotating the reverse shaft of a motor that outputs rotational force. Therefore, it is better to use the electric brake as much as possible. Electricity can be increased, contributing to energy-saving operation.

Conventionally, in order to obtain as much regenerative energy as possible, a method has been proposed in which a brake notch switching decision is made to make the best use of an electric brake, and the decision result is displayed on the cab or applied to driving control. Yes. However, the electric brake response to the brake notch switching operation has a different time delay (transient response) due to circuit formation, transmission delay, and the like. In the conventional method, since the process of the transient response time is omitted by the timer, it is impossible to estimate the regenerative electric energy including the transient response and determine whether to switch the brake notch.

Hereinafter, embodiments will be described with reference to the drawings. In the following embodiments, the same components are denoted by the same reference numerals, and repeated description is omitted.

In the first embodiment, a regenerative electric energy estimation device will be described.

FIG. 1 is a table showing an example of the relationship between the brake notch and the expected regenerative power. As shown in FIG. 1, by knowing in advance the regenerative power (expected regenerative power [kW]) that will be obtained for the brake notch, the expected regenerative power can be determined from the time transition of the brake notch in any operation section. It is possible to calculate the expected regenerative electric energy that is the time integral value of. This is the simplest method and does not consider the effects of information other than brake notches. In the example of FIG. 1, the number of steps of the brake notch takes four steps from 0 to 3, but any number of steps may actually be used.

FIG. 2 is a diagram illustrating an example of a time transition of the brake notch and the regenerative power. The horizontal axis represents time, the vertical axis represents the brake notch and the regenerative power [kW], the solid line represents the brake notch, and the broken line represents the regenerative power. As shown in FIG. 2, the regenerative electric power for the switching operation of the brake notch has a time delay (transient response) due to circuit formation or transmission delay with respect to the instant at which the brake notch is switched. When only the relationship shown in FIG. 1 is used, this transient response cannot be taken into account, and therefore the estimation accuracy of the expected regenerative power amount with respect to the actual regenerative power amount is deteriorated.

Therefore, in the present embodiment, attention is paid to the fact that the characteristics of the transient response change depending on the combination of the brake notch before switching and the brake notch after switching in the brake notch switching operation. Then, a model for estimating the regenerative power for each switching operation of the brake notch is constructed.

FIG. 3 is a table showing an example of the relationship between the brake notch before switching, the brake notch after switching, and the expected regenerative power in the embodiment. The row indicates the brake notch (0 to 3) before switching, the column indicates the brake notch (0 to 3) after switching, and each numerical value indicates the expected regenerative power [kW]. For example, assume that the brake notch at a certain estimation target time is 2. If the relationship of FIG. 1 is utilized, an expected regenerative electric power will be 1000 [kW]. Here, if the relationship of FIG. 3 is used, the expected regenerative power at the time, that is, the brake notch after switching is 2, differs depending on the brake notch immediately before the time. In the case of 0, 800 [kW], in the case of 1, 900 [kW], in the case of 2, since there is no switching, it remains 1000 [kW] (not defined in FIG. 3 and based on FIG. 1). Is 1100 [kW], and in summary, the expected regenerative power is in the range of 800 to 1100 [kW].

FIG. 4 is a diagram illustrating an example of distinguishing between the brake notch, the time transition of the regenerative power, and the transient response section. The transient response gradually converges to a steady state as time passes. Therefore, as shown in FIG. 4, A is defined as a transient response section, B is defined as a section other than the transient response, the relationship of FIG. 3 is used for the range of A, and the relationship of FIG. 1 is used for the range of B. You may do it.

In this way, by using the relationship of FIG. 3 or the relationship of both FIG. 3 and FIG. 1, the expected regenerative power is considered while considering the transient response of the regenerative power from the time transition of the brake notch in any operation section. The amount can be calculated. Therefore, compared with the case where only the relationship shown in FIG. 1 is used, the estimation accuracy of the expected regenerative power amount with respect to the actual regenerative power amount can be improved by considering the transient response.

FIG. 5 is a block diagram of the regenerative power amount estimation apparatus according to the embodiment. The regenerative power amount estimation apparatus 500 includes a regenerative power amount estimation unit 501 and a regenerative power estimation model 502 for each brake notch switching. The brake plan 503 is input, and the estimation result is output to the display unit 504. FIG. 5 corresponds to the configuration of each function described above.

FIG. 6 is a flowchart of the regenerative power amount estimation apparatus in the embodiment. FIG. 6 corresponds to the processing flow of each function described above. In the present embodiment, it is necessary to construct a regenerative electric energy estimation model 502 for each brake notch switching in advance. Specifically, this model refers to the table shown in FIG. 3 (the relationship between the brake notch before switching, the brake notch after switching, and the expected regenerative power), and the table shown in FIG. 10 described later (before switching). Brake notch, brake notch after switching, vehicle speed, and expected regenerative power). For example, the model 502 is constructed by acquiring railway vehicle operation data and totaling the data for each brake notch switching operation. This model can be stored in a storage device.

Processing is started (S601). First, the regenerative electric energy estimating apparatus 500 acquires time transition data (brake plan 503) of a brake notch for which the regenerative electric energy is to be estimated (S602). The regenerative power amount estimation unit 501 estimates the expected regenerative power amount that will be obtained in the input brake plan 503 based on the brake notch switching-specific regenerative power amount estimation model 502 (S603). And the expected regenerative electric energy estimated with the brake plan is output to the display part 504 (S604). Then, the process ends (S605).

Is added.

The gradient / curve information is information on a specific gradient and curve related to the trajectory. The vehicle speed is the operation speed of the vehicle, and usually has the same value in knitting, not by car number. The vehicle weight is the weight of the vehicle including passengers and other equipment, and has a different value for each car. The weather is information such as rain and snow at the service location. The overhead line voltage is a voltage applied to the motor from the overhead line through the pantograph, and has a different value for each car depending on the characteristics of the motor. The sliding state is a phenomenon of slipping that occurs when the adhesion of the vehicle wheel to the rail of the vehicle is weakened, and is information such as the presence / absence of the occurrence and a sign of the occurrence. In vehicle control, the braking force is controlled so that no sliding occurs. The vehicle combined state is information on whether or not different trains are connected.

In the second embodiment, the regenerative electric energy estimation unit estimates the expected regenerative electric energy by using these pieces of information together.

The regenerative power amount estimation unit estimates the expected regenerative power amount that will be obtained in the input brake plan based on the acquired information and the regenerative power amount estimation model classified by brake notch switching (S804). Then, the expected regenerative electric energy estimated together with the brake plan is displayed on the display unit (S804). The process ends here (S806).

FIG. 9 is a diagram illustrating an example of the relationship between the vehicle speed and the expected regenerative power. For example, with regard to the vehicle speed, it is known that the expected regenerative power increases as the vehicle speed increases, so the relationship as shown in FIG. 9 can be modeled in a linear format or the like. Therefore, it is possible to estimate the expected regenerative power with higher accuracy by considering the vehicle speed in the estimation of the expected regenerative power.

FIG. 10 is a diagram illustrating an example of the relationship between the brake notch before switching, the brake notch after switching, the vehicle speed, and the expected regenerative power in the embodiment. When the vehicle speed is considered as shown in FIG. 9, it can be modeled by a relational expression using the vehicle speed as a variable for each brake notch switching operation as shown in FIG.

As selection conditions for selecting a brake plan, conditions as shown in FIG. 15 are set in advance. These selection conditions can be freely switched as long as they are within a range that can be quantitatively evaluated. For example, the expression “the expected regenerative electric energy is maximum without sudden braking” shown in the selection condition 4 in FIG. 15 can be dealt with, for example, by defining an upper operation limit of the brake notch in a unit time interval.

The selected brake plan and the estimated expected regenerative electric energy are displayed (S1306). Thus, the process ends (S1307).

When planning a brake plan, for example, if the vehicle weight is large, more braking force is required, so the brake plan is generated while taking the vehicle weight into consideration. Other information may be taken into consideration as a variable of the relational expression, or a specific method of consideration may be considered, such as switching the relational expression.
