In this power generation system, for example, direct current power generated by a power generation unit 101 configured by a solar cell panel or the like is converted into alternating current power by a power conditioner 102 and connected to the commercial power system 200, and the household load 300 (or In this configuration, the AC power is supplied to the local load) and the surplus power is reversely flowed to the commercial power system 200. In addition, the power generation amount of the power generation unit 101 detected by the power generation amount measurement unit 111 and the current power purchase / sale status detected by the power trading status detection unit 113 (power sale or power purchase, if power sale, its power value, purchase The power consumption of the household load 300 is obtained by calculation in the power consumption measuring unit 112 of the power conditioner 102. Then, the power information display device 400 communicatively connected to the power generation amount measuring unit 111, the used power measuring unit 112, the power trading status detecting unit 113, and the power conditioner 102 enables the current power generation amount, the current used power, and the power trading. Predetermined power information is displayed in response to the output of power selling / buying information regarding the situation. Note that the power information display device 400 can receive only the power conditioner 102 to output the power sale / purchase information related to the current power generation amount, the current power usage, and the power trading status.

  FIG. 2 shows a more specific example of the power generation system. The power generation system is connected to a single-layer three-wire commercial power system by converting DC power generated by a power generation unit 1 mainly composed of a solar battery panel into AC power by a power conditioner 2, The AC power is supplied to the load 3 (or the on-site load) and the surplus power is configured to flow backward to the commercial power system.

  The single-layer three-wire lead-in line 5 of the commercial power system is connected to the switchboard 7 via a power purchase meter 6a and a power sale meter 6b. The switchboard 7 is provided with an ampere breaker 8 (contract breaker), an earth leakage breaker 9 and a safety breaker 10, and system power is supplied to the household load 3 via these breakers 8, 9, 10. In addition, the switchboard 7 is provided with a power measurement unit 11 that receives supply of system power from the safety breaker 10. The output of the power conditioner 2 is connected in parallel to the system at a connection portion 13 between the ampere breaker 8 and the earth leakage breaker 9 via the power generation breaker 12.

  Further, a current transformer (CT) 14 for detecting a current value flowing through the system is provided on the lead-in line 5 side with respect to the connecting portion 13, and the current transformer 14 is electrically connected to the power measuring unit 11. Connected, the detected value is supplied to the power measurement unit 11. In the illustrated example, the current transformer 14 is provided in each of the U phase and the V phase, but may be provided in only one of them.

  The power measurement unit 11 periodically calculates the average power related to the received power from the system per unit time based on the system voltage of the system power supplied from the safety breaker 10 and the current value detected by the current transformer 14. Data is calculated and the received power obtained by encoding the received power is sent to the power conditioner 2 via the first signal line 15 by serial communication. Instead of the received power, the received power amount per predetermined unit time (for example, 1 to 5 seconds) can be sent to the power conditioner 2 as data related to the received power. The received power obtained by the calculation is a positive value when power is purchased from the system (in the case of power purchase), and is negative when the power is flowing backward to the system (in the case of power sale). Depending on the presence or absence of this reverse power flow, it is possible to generate power selling / buying information about whether the power trading status is power selling or power buying. A binary signal (power sale / power purchase information) relating to the presence or absence of such reverse power flow is generated and output to the power conditioner 2 via the second signal line 16. Note that the second signal line is omitted and only the first signal line 15 is used, and the received power data and the signal indicating the presence or absence of reverse power flow are multiplexed by a multiplexer (not shown) provided in the power measurement unit 11. The multiplexed signal is supplied to the connection terminal 17 of the power conditioner 2 via the signal line 15 and is demultiplexed by a demultiplexer (not shown) provided on the power conditioner 2 side, and the data on the received power and the reverse power flow It is also possible to supply the control unit 21 with a signal indicating the presence or absence.

  The power measurement unit 11 can have a function of measuring not only the received power or the received power amount but also a gas amount or tap water amount consumed in the home, and the consumed gas amount or tap water amount. Can be sent from the power measurement unit 11 to the power conditioner 2 by serial communication as serial data.

  The power conditioner 2 includes a control unit 21, a DC / DC converter 22 that boosts and outputs DC power generated by the power generation unit 1, and an inverter 23 that performs DC / AC conversion on the output of the converter 22. The output of the inverter 23 becomes the output of the power conditioner 2. The control unit 21 is input with the data regarding the received power and the binary signal regarding the presence or absence of reverse power flow through the connection terminals 17 and 18 to which the first and second signal lines 15 and 16 are connected. Has been. The power conditioner 2 is provided with an instrument transformer 24 (system voltage detection means) for detecting the system voltage at the system connection point. The instrument transformer 24 is electrically connected to the control unit 21. The detected system voltage is input to the control unit 21. An external power information display device 4 is communicably connected to the power conditioner 2, and this power information display device 4 is installed indoors, and the built-in display control means receives the power trading status from the control unit 21. Receives various data related to the power status of the power generation system, such as power sale / power purchase information, current power generation amount, and current power consumption, and presents the current power status to the power status display monitor 41 Can be displayed. The power conditioner 2 and the power measuring unit 11 described above constitute the power generation amount measuring unit 111, the used power measuring unit 112, and the power trading status detecting unit 113 shown in FIG.

  The control unit 21 controls the reactive power control means 21a for suppressing the increase in the system voltage by controlling the power factor of the output AC power, the output suppression control means 21b for suppressing the active power of the output, and A disconnection control means 21c is provided that disconnects the power generation system from the system when the system voltage exceeds a predetermined voltage defined in the system interconnection regulations. Each of these means 21a, 21b, 21c may be realized by sequence control of a microcomputer, may be constituted by an FPGA, or may be realized by a dedicated control circuit for each means.

Next, display control by the display control unit for the power status display monitor 41 of the power information display device 4 will be described in detail with reference to FIG. The power status display monitor 41 can be constituted by, for example, a dot matrix LCD capable of color display. For the characteristic display control in the present embodiment, at least the output related to the current power generation amount and the current power consumption is used. It is possible to receive and use power selling / buying information that is determined based on the current power generation and current power consumption, but at least by receiving output related to the current power generation power and current power usage, If the following calculation / determination is performed using the information, the display control means obtains the power sale / power purchase information indicating whether the current power sale status is power sale or power purchase, and the power sale or power purchase value. Can do.
(Current power used-Current power generation amount) = X (1)
If X> 0, X indicates the power value of power purchase,
If X = approximately 0, it indicates an equilibrium state that does not belong to either power sale or power purchase,
If X <0, X indicates the power value of power sale.

  Then, the display control means performs the following display on the power status display monitor 41 based on the values of the current power generation amount and the currently used power. That is, as shown in FIGS. 3A and 3B, the power status display monitor 41 is divided into three regions in the left-right direction, and the power generation amount for displaying the power generation amount in one side region (left side region) in the left-right direction. The display unit 43 is set as a region, the power consumption display unit 44 for power consumption display is set for the other region (right region) in the left-right direction, and power is sold or purchased for the central region in the left-right direction between the two. The power sale / power purchase display section 42 for such power sale / power purchase display is set as an area. The power sale / power purchase display unit 42 is set as a virtual fulcrum at a specific position in the middle in the vertical direction in the central region in the left-right direction, and is set as a region surrounding the fulcrum (circular region in the illustrated example). Character display (character display of “power sale” or “buy power”) related to information on whether to sell or buy power as a power sale / buy display for the power sale / buy display section 42, and the power value of the power sale Alternatively, a numerical display of the power value of the purchased power is displayed. Similarly, the power generation amount display unit 43 set in a predetermined shape (circle in the illustrated example) has its display position changed in the vertical direction according to the current power generation amount, while the region is set in the same shape. The display position of the used power display unit 44 is also changed in the direction opposite to the display position change direction of the power generation amount display unit 43 with respect to the vertical direction in accordance with the amount of the currently used power (see FIG. 3 (a), (b) (see the circular area indicated by the alternate long and short dash line, three-dot chain line).

  The change in the vertical position of the power generation amount display area 43 and the power consumption display area 44 is stepwise or not depending on the magnitude of each value of the current power generation amount and the current power consumption used in the above equation (1). It is supposed to be executed in stages. When changing in multiple stages, it is possible to set the number of stages and a threshold value that defines which stage belongs in advance, and to determine the stage of the vertical position by comparison with this threshold value. it can.

  More specifically, the display control for changing the vertical position in stages is more specifically the left power generation amount display unit 43 and the right use with the central point of the power sale / buy display unit 42 as a virtual fulcrum. The power generation amount display unit 43 and the used power display unit 44 are moved to the opposite sides with respect to the vertical direction so that the vertical position with the power display unit 44 maintains a point-symmetrical relationship. Accordingly, if the dividing line 45 extending in the left-right direction so as to connect the center points of the power generation amount display unit 43, the power sale / power purchase display unit 42, and the used power display unit 44 is displayed, the power sale / power purchase display unit Like a seesaw with the center point of 42 as a fulcrum, the left power generation amount display unit 43 and the right used power display unit 44 are moved up and down in the vertical direction to change the display position.

  In the specific example of FIG. 3, when the current power generation amount and the current power usage are in equilibrium with each other (X = 0), the power generation display portion 43 and the power usage display with the power sale / power purchase display portion 42 interposed therebetween. The part 44 is displayed at the same position as the power selling / buying display part 42 in the vertical direction, and the partition line 45 is displayed in a state of extending horizontally (the solid line in FIGS. 3A and 3B). (See lot line). If the current power usage is larger than the current power generation amount, and the X in equation (1) is a positive value (X> 0; power purchase), the power value of the power purchase increases, The display position of the power generation amount display unit 43 is moved downward, and the display position of the power consumption display unit 44 is moved stepwise (see FIG. 3A). In this case, the lane marking 45 is a leftward downward slope line, and the slope step is displayed so that the slope step increases as the step progresses. On the other hand, if the current power consumption is smaller than the current power generation, and X in equation (1) is a negative value (X <0; power sales), then the power sales power value (X The display position of the power generation amount display unit 43 is moved upward, and the display position of the used power display unit 44 is moved stepwise toward the lower side (see FIG. 3B). ). In this case, the lane marking 45 becomes a rightward downward sloping inclination line, and is displayed so that the inclination step increases each time the step proceeds.

  In the case of X = 0, which is indicated by a solid line in each of FIGS. 3A and 3B, the character display of “Power Sale” is displayed at the upper position of the power sale / buy display section 42, and at the middle position. A numerical value display of “0.0 kW” is displayed as the power value, and a graphic display of a circle, which is a unit of money meaning a loss / loss account, is displayed at the lower position. In this case, for the sake of convenience, an example in which “power sale” is displayed at the upper position is shown. However, the “profit” due to power sale and the “loss” due to power purchase are almost zero. Instead of “power sale”, “power purchase” can be displayed, “power sale / power purchase” can be displayed, or no power can be displayed. In addition, the power generation amount display section 43 displays a character display of “power generation” at the upper position, a numerical display of, for example, “2.0 kW” as the power value at the middle position, and imagines power generation at the lower position. A graphic display is displayed. In addition, the power consumption display section 44 displays a character display of “power consumption” at the upper position, a numerical value display of, for example, “2.0 kW” as the power value at the middle position, and uses power at the lower position. An imaged graphic display (for example, a graphic display of an outlet) is displayed. In the range where the value of X, which is the calculated value of the equation (1), is in the range of 0 plus or minus a minute value, it is possible to perform processing that considers X = 0 in consideration of hysteresis.

  Note that, in any of the display units 42 to 44, the size of the numerical display is highlighted more greatly than other displays. In any of the display units 42 to 44, the character display, the numerical display, and the graphic display can be colored with mutually different colors. For example, the power generation amount display unit 43 can be displayed in red, and the used power display unit 44 can be displayed in green. Furthermore, a colored color (chromatic color) is applied to the region on one side (for example, the lower side) in the vertical direction across the lane marking 45, and the coloring is applied to the case of selling electricity, Different colors can be used in the case of electricity. For example, it can be colored blue in the case of power sale, and orange in the case of power purchase. By doing so, it is possible to visually distinguish between blue and orange even from a relatively long distance, so whether the current power trading status is selling or buying electricity, or whether it is gaining or losing. It can be easily distinguished and distinguished. Furthermore, by changing the degree of shading of the coloring according to the inclination stage (gradient) described later, even if the current power trading status is at a glance even from a distance, it is a power purchase or a power purchase. However, it is possible to easily grasp whether the degree is large or small, or whether the degree of gain / loss is large or small.

  Further, the belt-like region at the lower edge of the power status display monitor 41 is divided into three in the left-right direction, and assigned as a graph / data button 481, a fee button 482, and a menu button 483 by a touch panel method. By pressing the graph / data button 481, the amount of power generation over time, the amount of power used, etc. is switched to a display screen that is displayed as a graph or data, and by pressing the charge button 482, a specific power sale or power purchase By switching to a display screen for displaying charges or by pressing a menu button 483, the display screen is switched to a display screen for making various menu selections.

  Next, a specific method for moving and displaying the power generation amount display unit 43 and the used power display unit 44 stepwise in the vertical direction as described above will be described with reference to the example of FIG. FIG. 4A shows threshold values used in the case of power sale (when X <), and FIG. 4B shows examples of threshold values used in case of power purchase (when X> 0). In the case of power sales, the rated power generation scale (for example, 3.0 kW system, 4.3 kW system, 5.8 kW system, etc.) of the power generation system as to how many photovoltaic power generation panels 1,101 are configured, Threshold values (for example, less than 20%, 20% or more to less than 50%, 50% or more, etc.) for moving and displaying in three stages are set in advance in the display control means, and are the power values of power sales ( 1) Calculate the percentage of the rated power generation amount of X (absolute value) in equation (1) if the calculated value is less than 20%, for example, the first step, and if it is 20% or more and less than 50%, the second step. If the value is 50% or more, the third step is determined. The power value of less than 20% exemplified as the first stage is a numerical value assuming, for example, the power generation amount when cloudy or the power generation amount in the early morning / evening even when it is clear, and more than 20% exemplified as the second stage The power value of ˜less than 50% is a numerical value that assumes the amount of power generation between morning and daytime except for the vicinity of noon on a sunny day, for example, and the power value of 50% or more exemplified as the third stage is, for example, a sunny day It is a numerical value that assumes the amount of power generation at peak time around noon on the day. Therefore, other numerical values may be adopted as specific threshold values.

  If the inclination stage is the first stage, as shown in FIG. 5A, for example, the power generation amount display unit 43 in the left area is set slightly above the display position of the power sale / buy display unit 42. On the other hand, the power consumption display section 44 in the right region is set slightly below the display position of the power sale / buy display section 42. In addition, the upper region 46 from the partition line 45 is uncolored or a light background color, while the lower region 47 from the partition line 45 is colored blue. As a result, it is possible to easily grasp visually that the current power purchase / sale status is power sale, even from a distance. If the tilt stage is the second stage, for example, as illustrated in FIG. 5B, the power generation amount display unit 43 in the left region is positioned further above the display position of the first stage. The power consumption display section 44 in the right region is set further below the display position of the first stage. In addition, as in the case of the first stage, the upper region 46 from the dividing line 45 is made uncolored or a light background color, while the lower region 47 from the dividing line 45 is colored in blue. In this case, since the inclination state of the lane marking 45 is changed more strongly and the shape of the blue colored region (lower region 47) changes, the degree of power sale has changed more than in the first stage. Can be easily grasped visually. Further, if the tilting stage is the third stage, the power generation amount display unit 43 in the left region is positioned further above the display position of the second stage as illustrated in FIG. 5C, for example. The power consumption display section 44 in the right area is set further below the display position of the second stage. In addition, as in the first stage and the second stage, the upper region 46 from the division line 45 is uncolored or a light background color, while the lower region 47 from the division line 45 is colored in blue. Is done. In this case, since the blue colored region is changed more strongly than the case where the inclination state of the lane marking 45 is changed in the second stage and the shape changes greatly, the degree of power sale is lower than in the first and second stages. It becomes possible to easily grasp visually that the change has been made even more greatly.

  On the other hand, in the case of power purchase, as shown in FIG. 4 (b), threshold values (for example, less than 500W, 500W to less than 1.0kW, 1 If the value of X in the formula (1), which is the power value of power purchase, is less than 500 W, for example, the first stage, 500 W or more to 1.0 kW If it is less, the second stage is determined, and if it is 1.0 kW or higher, the third stage is determined. The power value of less than 500 W exemplified as the first stage represents the power consumption in a state in which little power is consumed, such as standby power only even when the user is absent or at bedtime, or at home in the daytime. The power value of 500 W or more and less than 1.0 kW exemplified as the second stage is assumed to be a numerical value representing power consumption in a state where the user normally lives at home, for example. Furthermore, although the power value of 1.0 kW or more exemplified as the third stage is normally living at home, a large household load (for example, an air conditioner or a microwave oven) is used. It is assumed that the value represents the power consumption. Therefore, other numerical values may be adopted as specific threshold values.

  If the inclination stage is the first stage, for example, as illustrated in FIG. 6A, the power generation amount display unit 43 in the left region is set slightly below the display position of the power sale / buy display unit 42. On the other hand, the power consumption display unit 44 in the right region is set slightly above the display position of the power sale / buy display unit 42. In addition, the upper region 46 from the dividing line 45 is colored or uncolored as in the case of selling electricity, while the lower region 47 from the dividing line 45 is colored orange. Unlike blue in the case of power sales, orange coloring is added in the case of power purchase, so it is easy to visually confirm that the current power trading status is power purchase even from a distance. It becomes possible to grasp. If the tilt stage is the second stage, as shown in FIG. 6B, for example, the power generation amount display unit 43 in the left area is set further below the display position of the first stage. The power consumption display section 44 in the right area is set further above the display position of the first stage. In addition, as in the case of the first stage, the upper region 46 from the division line 45 is uncolored or a light background color, while the lower region 47 from the division line 45 is colored orange. In this case, as in the case of the power sale, the inclined state of the lane marking 45 is changed more strongly, and the shape of the orange colored region (lower region 47) changes. It becomes possible to easily grasp visually that the degree of has changed more greatly. Furthermore, if the inclination stage is the third stage, the power generation amount display unit 43 in the left region is set further below the display position of the second stage as illustrated in FIG. 6C, for example. The power consumption display section 44 in the right area is set further above the display position of the second stage. In addition, as in the first stage and the second stage, the upper area 46 from the division line 45 is uncolored or a light background color, while the lower area 47 from the division line 45 is colored orange. Is done. In this case, since the orange colored region is changed more strongly than the case where the inclination state of the lane marking 45 is changed in the second stage and the shape changes greatly, the degree of power purchase is lower than that in the first and second stages. It becomes possible to easily grasp visually that the change has been made even more greatly.

  In the case of the power information display device of the above embodiment, the current power selling / purchasing status in the power generating device interconnected with the commercial power system, in particular whether the power used or the power generation amount is large, In other words, whether the power trading status is selling or buying electricity, whether it is being obtained by selling electricity or whether it is necessary to pay a fee by buying electricity, and in addition to what degree This information can be easily grasped visually at a glance even from a relatively long distance.

<Other embodiments>
In addition, this invention is not limited to the said embodiment, Other various embodiment is included. For example, although the example of the solar power generation system has been described in the above-described embodiment, the power generation system using other natural energy (for example, wind power or tidal power), or the power generation system other than natural energy which does not allow reverse power flow at present. (For example, a fuel cell power generation system, a gas engine power generation system, etc.) can be applied if there is a future revision of the legal system.

  When the display position of the power generation amount display unit 43 and the used power display unit 44 is changed and displayed so as to move stepwise in the vertical direction, it is moved in three steps as in the above embodiment, for example, in four steps or five steps. Any number of steps can be set as required. In addition, with respect to setting of a threshold value for changing and displaying in stages, a threshold value setting method as to what percentage of the rated power generation amount (rated output) the power value of the power sale as shown in FIG. Can also be applied to the case of power purchase, or conversely, a threshold value setting method for the power range of power purchase as shown in FIG. It can also be applied to the case of selling electricity. Further, as the threshold value, for example, the threshold value of FIG. 4B is used only in the late-night time zone in which power generation is almost impossible or household load is hardly consumed, and the same threshold value as in FIG. 4A is used in other time zones. Can be used. Furthermore, in FIG. 4 (a), the threshold is set from the viewpoint of the percentage of the rated power generation amount. However, the threshold is not limited to this. For example, a predetermined period such as the past several months or the past one week is used. The maximum and minimum values of the difference between the power generation amount and the power used are updated by learning, and a threshold is set from the viewpoint of what percentage of the difference between the maximum value and the minimum value. be able to.

  In the embodiment, the horizontally long power status display monitor 41 is divided into three regions in the left-right direction, the power generation amount display unit 43 is set for the left region, and the used power display unit 44 is set for the right region. The power selling / buying display unit 42 is set for the central region in the left-right direction between the two, and the power generation amount display unit 43 and the power consumption display unit 44 are moved up and down according to the value of X in the equation (1). The display position is changed so as to move in the opposite directions with respect to the direction, but this is rotated 90 degrees in the plane direction around the power selling / buying display section 42 and the vertically long power situation Can be displayed. That is, as illustrated in FIG. 7, the vertically long power status display monitor 41a is divided into three regions in the vertical direction, the power generation amount display unit 43a is set for the upper region, and the used power is displayed for the lower region. The area 44a is set as an area, the power sale / buy display section 42a is set for the central area in the vertical direction between the two, and the power generation amount display section 43a and the usage amount are selected according to the value of X in the equation (1). The display position can be changed stepwise or steplessly so that the power display unit 44a moves to the opposite sides with respect to the left-right direction. In addition, one of the regions 46a and 47a (right region 47a) on both sides in the left-right direction across the lane marking 45a is sold in the case of selling power, for example, blue, and in the case of buying power, for example, orange. What is necessary is just to give coloring of a mutually different color with electricity. Note that a method similar to the method described in the above embodiment may be applied to the method of changing the display position in stages using the threshold value.

  As a coloring example of one side area across the lane marking 45, blue is shown as an “obtain” image in the case of power sale, and orange is shown as an “damage” image in the case of power purchase. Other color combinations can be employed. For example, green coloring may be added in the case of power sale, and red coloring may be added in the case of power purchase.
