Description

An embodiment of the present invention relates to a regenerative electric energy estimation device and a brake planning device.

In operation of a railway vehicle, a driver stops a train at a target position by operating a brake notch of a master controller provided in a cab. The command of the master controller is transmitted to the vehicle control device, and the vehicle control device calculates a braking force necessary for the train to decelerate and stop corresponding to the brake notch operation. The brake consists of an electric brake and a friction brake. Basically, the electric brake is given priority, and when the required braking force cannot be obtained, the friction brake assists. The electric brake is a method of operating (regenerating) as a generator by applying a reverse rotation to a motor that normally outputs a rotational force to brake the electric motor. The amount of electric power increases, which can contribute to energy-saving operation.

Conventionally, in order to obtain as much regenerative electric energy as possible, a method has been proposed in which a brake notch switching judgment that maximizes the use of the electric brake is performed, and the judgment result is displayed on a cab or applied to operation control. I have. However, the response of the electric brake to the switching operation of the brake notch has a different time delay (transient response) due to circuit formation, transmission delay, and the like. In the conventional method, the processing of the time of the transient response is omitted by the timer, so that it is not possible to estimate the regenerative electric energy including the transient response and determine the switching of 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 overlapping description will be omitted.

First Embodiment In a first embodiment, a regenerative power amount estimation device will be described.

FIG. 1 is a table showing an example of a relationship between a brake notch and expected regenerative power. As shown in FIG. 1, by knowing in advance the regenerative power (expected regenerative power [kW]) that can be obtained for the brake notch, the expected regenerative power can be calculated from the time transition of the brake notch in any operation section. The expected regenerative electric energy, which is the time integrated value of the above, can be calculated. This is the simplest method and does not take into account the effects of information other than the brake notch. In the example shown in FIG. 1, the number of brake notches is four from 0 to 3, but may be any number.

FIG. 2 is a diagram illustrating an example of a time transition of the brake notch and the regenerative electric power. The horizontal axis indicates time, the vertical axis indicates brake notch and regenerative power [kW], the solid line indicates brake notch, and the broken line indicates regenerative power. As shown in FIG. 2, the regenerative power for the switching operation of the brake notch has a time delay (transient response) due to circuit formation, transmission delay, and the like with respect to the time at the moment of switching the brake notch. When only the relationship shown in FIG. 1 is used, the transient response cannot be taken into consideration, so that the accuracy of estimating the expected regenerative power with respect to the actual regenerative power is deteriorated.

Therefore, in the present embodiment, attention is paid to the fact that the transient response characteristic changes due to the combination of the brake notch before switching and the brake notch after switching in the switching operation of the brake notch. A model for estimating the regenerative power for each brake notch switching operation is constructed.

FIG. 3 is a table illustrating an example of a relationship between a brake notch before switching and a brake notch after switching and expected regenerative power in the embodiment. The row indicates the brake notch (0-3) before switching, the column indicates the brake notch (0-3) after switching, and each numerical value indicates the expected regenerative power [kW]. For example, it is assumed that the brake notch at a certain estimation target time is 2. Using the relationship in FIG. 1, the expected regenerative power is 1000 [kW]. Here, using the relationship in FIG. 3, the expected regenerative power at the time, that is, when the brake notch after switching is 2, differs depending on the brake notch immediately before the time. In the case of 0, it is 800 [kW], in the case of 1, 900 [kW], in the case of 2, there is no switching, so it remains 1000 [kW] (not specified in FIG. 3 and based on FIG. 1). Is 1100 [kW], which is an expected regenerative power in the range of 800 to 1100 [kW].

FIG. 4 is a diagram illustrating an example of the distinction between the time transition of the brake notch and the regenerative power and the transient response section. The transient response gradually converges to a steady state over time. 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, and the relationship of FIG. 3 is used for the range of A, and the relationship of FIG. You may.

As described above, by utilizing the relationship in FIG. 3 or both the relationship in FIG. 3 and FIG. 1, from the time transition of the brake notch in an arbitrary operation section, the expected regenerative power is considered while considering the transient response of the regenerative power. The amount can be calculated. Therefore, compared with the case where only the relationship shown in FIG. 1 is used, the accuracy of estimating the expected regenerative electric energy with respect to the actual regenerative electric energy can be improved by considering the transient response.

FIG. 5 is a block diagram of the regenerative electric energy estimation device according to the embodiment. The regenerative electric energy estimating apparatus 500 includes a regenerative electric energy estimating unit 501 and a regenerative electric 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 electric energy estimation device according to the embodiment. FIG. 6 corresponds to the processing flow of each function described above. In the present embodiment, it is necessary to construct a model for estimating the regenerative electric energy for each brake notch switching 502 in advance. Specifically, this model includes the table shown in FIG. 3 (the relationship between the brake notch before switching and the brake notch after switching and the expected regenerative power) and the table shown in FIG. Relationship between the brake notch, the brake notch after switching, the vehicle speed, and the expected regenerative electric power). For example, the model 502 is constructed by acquiring operation data of a railway vehicle and totalizing the data for each switching operation of the brake notch. This model can be stored in a storage device.

The process starts (S601). First, the regenerative electric energy estimating apparatus 500 acquires the time transition data (brake plan 503) of the brake notch for which the regenerative electric energy is to be estimated (S602). The regenerative electric energy estimating unit 501 estimates an expected regenerative electric energy that will be obtained in the input brake plan 503 based on the brake notch switching-specific regenerative electric energy estimation model 502 (S603). Then, the estimated regenerative electric energy estimated together with the brake plan is output to the display unit 504 (S604). Thus, 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 operating speed of the vehicle, and usually has the same value for each train, not for each car. The vehicle weight is the weight of a vehicle including passengers and other facilities, and has a different value for each car. The weather is information such as rain or 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 according to the characteristics of the motor and the like. The sliding state refers to a sliding phenomenon that occurs when the adhesion of the wheels of the vehicle to the rails is weakened, and is information such as the presence / absence of the occurrence and a sign of occurrence. In the vehicle control, the braking force is controlled so that no gliding occurs. The vehicle combination state is information on whether or not formations of different systems are connected.

In the second embodiment, the regenerative power amount estimating unit estimates the expected regenerative power amount using these pieces of information.

The regenerative electric energy estimating unit estimates an expected regenerative electric energy that would be obtained by the input brake plan based on the acquired information and the regenerative electric energy estimation model for each brake notch switching (S804). Then, the estimated regenerative electric energy estimated together with the brake plan is displayed on the display unit (S804). Thus, the process ends (S806).

For example, regarding the vehicle speed, it is known that the expected regenerative electric power increases as the vehicle speed increases. Therefore, the relationship as shown in FIG. 9 can be modeled in a linear form or the like. Therefore, by considering the vehicle speed in estimating the expected regenerative power, it is possible to more accurately estimate the expected regenerative power.

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

FIG. 11 is a diagram illustrating an example of the relationship between vehicle speed, weather, and expected regenerative power. Weather information is further added to the relationship of FIG. 9, and the model of the relationship of FIG. 9 can be switched for each weather such as sunny, rain, and snow.
