Description

The present invention relates to a renewable energy power generation control education device and a system equipped with the same, which allows learning the control mechanism of a power generation device that generates power using renewable energy from an engineer's perspective.

Wind power generation, hydropower generation, solar power generation, etc. are common examples of power generation using renewable energy. For these power generation, an appropriate control method is selected and control parameters are set depending on the type of renewable energy.
The efficiency of wind and hydroelectric power varies greatly depending on the combination of voltage (≒ rotation) and current (≒ torque). Therefore, the control device usually sets these relationships according to the load to maximize efficiency. In the case of wind power generation, map control is often used to predefine the relationship between voltage and current according to the load because the wind response is quick. On the other hand, since sunlight moves relatively slowly, maximum efficiency point tracking control (MPPT control) is often used.

Note that Patent Document 1 has been proposed as an example of a disaster prevention base facility as a facility that performs wind power generation and solar power generation and monitors the operating state.

It is not easy to change control parameters related to wind power generation/hydro power generation or solar power generation control, and it is difficult for people without knowledge to do so. Users often operate these power generation devices using renewable energy according to the specified values set by the manufacturer without being aware that they have characteristics related to efficiency. The efficiency of wind power generation and solar power generation varies depending on the control parameters, so if the user can change the control parameters, high efficiency can be achieved by setting the optimal control parameters according to the situation. However, it is not easy for users or those who want to learn to make appropriate changes.

By actually operating the power generation device by changing the control parameters, it becomes easy to understand what kind of performance difference there is due to the difference in the control parameters. However, if incorrect control parameters are set for a power generation device in actual operation, it will cause a significant drop in the generated power supplied to the grid, etc., and in the case of wind power generation, there is a risk that the wind turbine will over-speed. Until now, there has been no educational system that allows students to learn the differences in performance due to differences in the control parameters of power generation equipment.

This invention solves the above problems, and its purpose is to provide a renewable energy power generation control education device that allows users to arbitrarily set control parameters and learn how characteristics differ depending on the control parameters. and systems.

A control means 4 that is provided between a power generation device 2 that generates electricity using renewable energy and a power supply target 3 to control the power supply;
a communication unit 6 that wirelessly communicates with a terminal 5 capable of inputting information;
a parameter changing unit 7 that receives an input operation from the terminal 5 at an arbitrary timing and changes a control parameter P of the control means 4 according to the input operation;
The power generation device 2 and any part of the power supply route from the power generation device 2 to the power supply target 3 are monitored, and the content obtained through the monitoring is displayed on either or both of the screens of the monitor 8 and the terminal 5. a condition monitoring unit 9;
safety means 10 for protecting the power generation device 2 against abnormalities in the control parameter P;
Equipped with.

The renewable energy is wind power, water power, sunlight, etc., and the power generation device 2 is a wind power generation device 2B, a hydroelectric power generation device 2C, a solar power generation device 2A, etc. The power supply target 3 is a battery 15, a commercial power grid 16, etc., and may be a power consumption facility in a specific premises. The terminal 5 capable of inputting information is, for example, a general-purpose terminal connectable to the Internet or a LAN, such as a smartphone 5A, a tablet terminal 5B, or a personal computer (not shown). The communication unit 6 performs wireless communication compatible with a wireless LAN (LAN) such as Wi-Fi that can be connected to the Internet, or one-to-one short-distance wireless communication standard such as Bluetooth. It is a means for carrying out the communication, and is composed of a communication module 6A and the like. The safety means 10 may be configured to operate regardless of the control parameter P, or may be configured to limit the input range of the control parameter P.

Electric power generated from feng shui power or sunlight is supplied to the control means 4 and then supplied to the power supply target 3 such as the battery 15 or the grid 16. In general, power control methods are broadly divided into map methods that determine how to use power in advance and methods that control the power by aiming for the maximum efficiency point. In addition to these, output suppression control or the like may be used. The selection of these control methods and the setting of control parameters P in the control methods are often priced according to the feng-shui power or solar power generation device 2 to be controlled, and are specified according to the control object. There is a need.

According to the configuration of the present invention, since it is configured as a control education device 1 exclusively for education, unlike a control device for a power generation device to be actually operated, it is possible to operate the power supply target 3 assuming performance deterioration etc. in advance. Even if the parameter P becomes an abnormal value and the generated power drops extremely or becomes unstable, no actual damage will occur due to a drop in the power supplied to the grid 16 or the like. Further, since the safety means 10 is provided, the power generation device 2 is protected even if the control parameter P is changed to an abnormal value.
The input for changing the control parameter P is through the terminal 5 that communicates wirelessly, and the user can use a smartphone 5A, a tablet terminal 5B, or the like that the user is accustomed to operating.
For these reasons, anyone can easily change the control parameter P and view the results monitored by the condition monitoring unit 9 on the monitor 8, thereby changing the amount of power generated due to different characteristics of the power generation device 2 that generates power using renewable energy. You can experience the difference. In other words, you can understand the characteristics of the controlled object and experience for yourself why optimal control is necessary.

The renewable energy power generation control training device 1 of the present invention may include a control program changing unit 39 that can change the control program 32 that controls the power supply of the control means 4.

If the control program 32 is changeable, it is possible to incorporate the control theory of renewable energy power generation, such as the control theory of wind turbines, and various protection functions, thereby providing a learning experience of the embedded system. If a simple programming language such as Scratch is used as the control program 32, program design can be experienced more easily.
In recent years, attention has been paid to programming, with programming education becoming compulsory. The control training device 1 of the present invention is a tool that can learn about control objects such as renewable energy power generation devices 2, which are attracting attention in the future, and learn how to assemble a control program 32 by actually operating them.
Feng Shui power and sunlight control are based on control theories such as feedback control. This control concept is used for power control, but it is also commonly used in everyday home appliances such as rice cookers. Engines and motors in automobiles also have characteristics related to efficiency, and the idea is the same. Therefore, by learning the actual control with this renewable energy power generation control education device 1, it will be possible to acquire knowledge of control design that can be used in a wide range of fields, such as controlling automobiles and household appliances around us. .

If there is a function to display the simulation results on the monitor 8, it is possible to grasp the operation when the control program 32 is changed before actually controlling the power generation device 2, and it is also possible to modify the control program 32 many times. This makes it easy and quick to understand the results.

In the renewable energy power generation control training device 1 of the present invention, the safety means 10 may have a function of stopping the power generation device 2 when a set condition is satisfied. For example, the safety means 10 may include a hardware stopping device 10a such as a brake, and a determining means 10b that determines whether a set condition for performing the braking operation or the like is satisfied.
Since the control training device 1 of the present invention is used for learning control, it is possible that the user has little control knowledge. Therefore, it needs to be safe even when used by learners who are inexperienced in control technology.

If the user changes the control parameter P to an inappropriate value, this is often not a problem in the case of solar power generation, but in the worst case, in the case of wind-hydro power generation, the rotation speed of the wind turbine 11 increases and the blades break down. may lead to. For this reason, a hardware stopping device 10a that does not require control is provided as the safety means 10, and the stopping device 10a is capable of automatically and safely stopping when set conditions are met, such as exceeding a rotational tolerance value. It is preferable to provide separately. This stopping device 10a may be a system that is separate from the control means 4, or may be configured such that an analog circuit or the like automatically determines when the voltage (≒ rotational speed) exceeds a certain threshold value and activates the stopping operation. It's okay.

In this embodiment, the control means 4 is composed of a control device 21 serving as a main body of the control means, and a personal computer 22 (hereinafter referred to as "PC22"). Note that the control means 4 may be configured as a control device having the functions of the PC 22 without having the PC 22.

The control device 21 includes a power conversion section 23 that is a power circuit section, a control section 24 that controls the power conversion section 23, and the communication section 6. When a plurality of power generation devices 2 are connected to the same control device 21, a plurality of power conversion units 23 and control units 24 are basically provided corresponding to each power generation device 2. Even if a plurality of computer units are provided, the computer hardware and basic program constituting the control unit 24 are configured as one.
When a plurality of power generation devices 2 are connected to the same control device 21, the power conversion section 23 and the control section 24 may be provided as one each so that they can be switched and used.

The power conversion unit 23 is a device into which the power generated by the generator 2 is input, processes the input power, and outputs the processed power to the power supply target 3. The power converter 23 includes, for example, a converter 25 and an inverter 26.

The value of each control parameter P is stored in the parameter registration section 33, which is a storage area determined by the control program 32 or the like, in the computer constituting the control section 24.

For example, as shown in FIG. 2, the control method of the output command unit 31 uses MPPT control, which monitors the amount of change in current with respect to the amount of change in voltage ΔV per unit time, and changes the voltage using a hill-climbing method to aim for the maximum efficiency point. It will be done. Alternatively, as shown in FIG. 3, map control may be used that shows the relationship between voltage and current values with respect to changes in voltage. In the case of wind power generation and hydropower generation, the voltage is proportional to the rotation speed, and the current commands the torque. In addition to these methods, output suppression control or the like may be used as a control method for the output command unit 31.
Generally, MPPT control is used in solar power generation, and map control is used in wind power generation and hydroelectric power generation, but in this embodiment, by changing the control program 32 by a control program change unit 39 described later, It is possible to select a control method and change the control content within the same control method.

The communication module 6A is a device that performs wireless communication. The communication unit 6 is also connected to the PC 22 by the communication module 6A or by another communication interface (not shown).

The parameter changing unit 7 is a means for accepting an input operation from the terminal 2 at an arbitrary timing and changing the control parameter P according to the input operation.

Update to parameter P.

To give a specific example, the parameter changing unit 7 displays, on the screen of the terminal 5 in response to access from the terminal 5, a screen (not shown) including a guide prompting input of the control parameter P and a writable area. Then, new storage in the parameter registration section 33 or change of the stored contents is performed according to the value written in the writable area. The writable area displayed on the screen of the terminal 5 may be a display that allows you to enter a numerical value such as an input box, or a display that allows you to select multiple numerical values arranged in a row. It may be an indication that specifies the If there are multiple types of control parameters P, the writable areas may be displayed side by side on the same screen, or may be displayed on different pages.

The state monitoring unit 9 monitors the power generation device 2 and any part of the power supply path from the power generation device 2 to the power supply target 3, and displays the contents obtained through the monitoring on the monitor 8 and the screen of the terminal 5. It is a means for displaying on either or both. The state monitoring unit 9 may be configured to monitor either the power generation device 2 or the power supply route.
In this embodiment, the voltage and current of the power output from the power conversion unit 23 are monitored by the voltage sensor 27 and current sensor 28 of the first sensor unit 29, and the second sensor unit 34 monitors the voltage and current of the power output from the power generation device 2.

The condition monitoring section 9 has a sensor detection means 9a that takes in the detection values of each of the sensors, and causes the monitor 8 and the terminal 5 to display the taken detection values. This display may be performed graphically or numerically. The condition monitoring unit 9 may display the stages in which each of the detected values is included, or may display them together with a predetermined reference value.
Note that the detected values of the voltage sensor 27 and current sensor 28 and the detected values of the wind meter 35, flow meter 36, and pyranometer 37 are also used to control the output command section 31 according to the contents of the control program 32. .

The PC 22 has an equipment design simulator 38 as one of its application programs. This equipment design simulator 38 is provided with a control program changing unit 39 that creates or changes the control program 32 that constitutes the output command unit 31.

The control program change unit 39 uses a programming language such as Scrack, which represents blocks consisting of combinations of programming commands, command groups, control parameters, etc. as illustrations on the screen, and allows a program to be created by selecting a block. Preferably, the configuration is such that the control program 32 can be created using a simple programming language. Further, the control program changing unit 39 makes it possible to select the type of control method (MPPT control, suppression control, map control, etc.) of the control program 32, sets selectable control operations for each type, and sets control operations that are selectable for each type. You may also be allowed to select.
The control program change unit 39 is also configured to be able to set the value of the control parameter P used in the control program P. The value of the control parameter P set at this time is an initial value, and can be changed by the parameter changing unit 7 according to the operation of the terminal 5.

In the automatic control mode, MPPT control, map control, output suppression control, pulse width modulation control, etc. are controlled for each type of power generation device 2, for example, solar power generation device 2A, wind power generation device 2B, and hydroelectric power generation device 2C. to select the control method, such as whether to Next, a specific control content such as a control formula in the selected control method is selected, and a value of a control parameter P used in the selected specific control content is input.
At each stage of selecting a control method, selecting specific control contents, and inputting control parameters P, the control program changing unit 39 displays, for example, text display of the name of the selectable control method on the screen of the PC 22. Illustrations containing the respective contents, illustrations containing selectable specific control content characters, mathematical formulas, etc., and illustrations containing characters such as the type of control parameter P are displayed. When the part where the illustration is displayed is selected using a cursor or the like on the screen, it is recognized that the control method and specific control content corresponding to the illustration have been selected. Regarding the control parameter P, the value of the control parameter P is recognized by selecting an illustration in which selectable values of the control parameter P are described, or by writing a numerical value in the numerical input part in the illustration. The illustrations of the selected selection stages are displayed in a predetermined display area of the PC screen in hierarchical order, thereby displaying the entire changed control program 32. In manual mode, the value of the voltage output from each solar power generation device 2A, wind power generation device 2B, and hydroelectric power generation device 2C that are directly controlled is determined, and how the amount of power generation changes by varying the voltage. You can check whether Even in the manual mode, changes can be made using illustrations on the screen of the PC 22, as in the automatic control mode.

In addition to the control program changing section 39, the equipment design simulator 38 also sends simulation results to the monitor 8 or the PC 22 when the power generation device 2 to be controlled is operated according to the control program P changed by the control program changing section 34.

If a simple programming language such as Scratch is used as the control program 32, program design can be experienced more easily.
In recent years, attention has been paid to programming, with programming education becoming compulsory. The control training device 1 of the present invention is a tool that can learn about control objects such as renewable energy power generation devices 2, which are attracting attention in the future, and learn how to assemble a control program 32 by actually operating them.

Control of power generation using renewable energy such as feng-shui power and solar power is based on control theories such as feedback control. This control concept is used in this kind of power control, but the engine and motor in a car have characteristics related to efficiency, so the concept is the same, and it is also commonly used in everyday home appliances such as rice cookers. . Therefore, by learning the actual control with this renewable energy power generation control education device 1, you will be able to acquire knowledge of control design that can be used in a wide range of fields, such as controlling automobiles and household appliances around you. Become.

The PC 22 equipped with the control program changing unit 39 has a design control simulator 38, and the simulation results of the power generation device 2 after changing the control program 32 are displayed on the monitor 8.

Can be done quickly.

The safety means 10 will be specifically explained. If the user changes the control parameter P, this is often not a problem in the case of sunlight, but in the worst case, with feng shui power, the rotation may increase and lead to failures such as flying off the blades. Therefore, in this control training device 1, a hardware stop device 10b that does not require control is provided, and a judgment means 10b is provided, and the judgment means 10b judges that the set condition is satisfied when the rotation tolerance is exceeded. A stopping device 10a is separately provided as a safety means 10, which enables automatic and safe stopping when the machine is stopped.

Therefore, in this embodiment, each power generation device 2 is housed in a container 41 such as a commercially available shipping container (ISO standard marine shipping container) so that it can be moved to a suitable location. Although not shown in FIGS. 5 to 7, the control device 21, monitor 8, etc. that constitute the control training device 1 are installed inside the container 41.
This container 41 can accommodate a solar panel 2Aa, a wind power generation device 2B, and a hydroelectric power generation device 2C that constitute the solar power generation device 2A as shown in FIG. The solar panel 2Aa, the wind power generation device 2B, and the hydroelectric power generation device 2C are designed to be easily deployable on-site, as shown in an installation example in FIG. 6, for example. In the example shown in the figure, the wind power generation device 2B has a vertical axis windmill as the windmill 11, and its support portion 2Bb is installed in the container 41. The solar panel 2Aa is installed on the ground on the top surface of the container 41 or near the container 41. The container 41 is installed near the waterway 47, and the hydroelectric power generation device 2C is installed astride the waterway 47. The waterway 47 is an agricultural or industrial waterway, a stream, or the like.

After deployment, there is a space S in the container 41 where people are present, and in this space S, as shown in FIG. equipment 43 can be installed. Using this space S, it is possible to operate and learn the control education device 1 using the smartphone 5A, tablet terminal 5B, PC 22, etc. It is preferable that the learning equipment 43 is also stored in the container 41 together with the power generation device 2 so that it can be transported. The desk 43A and chair 43B may be foldable.

The control education system in which the control education device 1 is installed in the container 41 can be installed in a disaster area and used as a power source in the event of a disaster , taking advantage of its transportability. In other words, it can be used for both learning purposes and emergencies. The power for driving the control training device 1 inside the container 41 can be taken from the local commercial power supply system, but it can also be supplied from the control training device 1 itself for renewable energy power generation.

In addition, although the said embodiment was equipped with the solar power generation device 2A, the wind power generation device 2B, and the hydroelectric power generation device 2C as the power generation device 2, these solar power generation device 2A, the wind power generation device 2B, and the hydropower generation device 2C are , one or both may be used.
