Description

The present invention relates to an autonomous operation system for distributed power sources.

In recent years, renewable energy has been actively introduced as a distributed power source, and its introduction is also progressing in ordinary households. For example, a fuel cell system that generates electricity by utilizing a chemical reaction between hydrogen and oxygen is known. In addition, a photovoltaic power generation system that generates electricity using a solar cell panel installed on the roof is also widespread. A system using such renewable energy normally operates in a grid-connected manner with a commercial power source, but can operate independently in the event of a power failure of the commercial power source and supply the generated power to the equipment. ..

That is, in the event of a power outage, the renewable energy (for example, the electric power generated by the fuel cell or the solar cell panel) can be directly used by switching from the grid interconnection operation to the independent operation. Specifically, an emergency outlet that is supplied via a special circuit in which the generated power is supplied as it is is installed, and the generated power can be used by connecting the plug of the device to the emergency outlet. Recently, a technique has been reported in which when the emergency outlet is energized by switching from grid interconnection operation to self-sustaining operation, the lamp provided in the emergency outlet is turned on to notify that the emergency outlet is energized. (For example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2010-259170

By the way, there are relatively few residents who forget the installation location (room) of the emergency outlet that can be used even during this power outage because there are few opportunities to use it. In addition, in order not to use it on a daily basis, a figurine such as a shelf may be placed in front of the emergency outlet to hide the emergency outlet. In such a case, even if the lamp provided in the emergency outlet is lit as in the above technique, the resident needs to search around the house to find the outlet in which the lamp is lit. And, in such a situation, it may not be possible to reach the place where the emergency outlet is installed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a distributed power source self-sustaining operation system that can easily reach an emergency outlet when the distributed power source is switched to self-sustaining operation.

This makes it easier to find in the building because the guide light emits light, so the guide light is an index for finding the emergency outlet. Even a resident who has forgotten the location of the emergency outlet can find the emergency outlet by searching for the guide light in the building and relying on the guide light. For example, if a guide light is installed near the emergency outlet, it is possible to immediately determine whether or not there is an emergency outlet in that room simply by looking over each room from the entrance, so it is easy to use the emergency outlet. You can get there.

The self-sustaining operation system of the distributed power source of the second invention is described in the first invention.

A fuel cell device 20 is installed on the outdoor side of the building 10. The fuel cell device 20 is a chemical reaction opposite to the electrolysis of water, in which hydrogen and oxygen are reacted to extract electricity.

Next, the electrical configuration of this system will be described with reference to FIG.

The fuel cell device 20 includes a fuel cell unit 21 and a controller 22. The fuel cell unit 21 is provided with a device for producing electricity by reacting hydrogen and oxygen, and a power conditioner for converting the generated DC power into AC power (not shown). The controller 22 is connected to the fuel cell unit 21 inside the fuel cell device 20 via a predetermined power path. The controller 22 includes a well-known microcomputer including a CPU, ROM, RAM, and the like.

The controller 22 has a control unit 22a, a storage unit 22b, and a timer 22c having a timekeeping function, a clock function, and a calendar function. The control unit 22a executes power generation control in the fuel cell unit 21 and control of switching between grid interconnection operation and independent operation. The storage unit 22b stores information on the amount of power generated by the fuel cell device 20, detection results from other devices, and the like. Further, the storage unit 22b stores the installation location (room) of the emergency outlet 15 and the guide light 18 (installation location or the like) associated with the emergency outlet 15.

A remote controller 23 (hereinafter referred to as a remote controller 23) that remotely controls the fuel cell device 20 is connected to the fuel cell device 20. The remote controller 23 is attached to the wall of the living room 12, for example. The living room 12 is, for example, a kitchen, and it is desirable that the living room 12 is installed in a place where the resident can understand the existence of the remote controller 23 from daily life. The remote controller 23 is provided with an operation unit 23a and a display unit 23b. The operation unit 23a is provided with a switch 23c for switching between grid interconnection operation and independent operation. The controller 22 controls the operation of the fuel cell device 20 based on the operation by the operation unit 23a and the pressing operation by the switch 23c.

The display unit 23b is a liquid crystal display, and normally displays the time by the timer 22c and displays the power generation amount of the fuel cell device 20 stored in the storage unit 22b. Then, in the case of a power failure, the display unit 23b displays a display for prompting switching between grid interconnection operation and independent operation, and displays the position of the emergency outlet 15 stored in the storage unit 22b. The display unit 23b is provided with a backlight 23d. By increasing the light intensity of the backlight 23d, the emission brightness of the display unit 23b (display) is increased, and the display unit 23b can be made to emit strong light.

In FIG. 1, commercial power of AC100V / 200V is supplied to the building 10 from the commercial power supply 31 via the transmission line 41. A distribution board 32 is connected to the transmission line 41. The distribution board 32 has a well-known distribution function for selectively supplying electric power to a plurality of electric power paths provided in the building 10. The distribution board 32 is connected to each of the living rooms 11 and 12 via the electric wiring 42. As a result, electric power is supplied from the distribution board 32 to a plurality of electric devices provided in the living rooms 11 and 12.

Here, the electric wiring 51 is connected to the fuel cell device 20, and the electric wiring 51 is branched into the electric wirings 52 and 53 by the changeover switch 26. The electrical wiring 52 is connected to the distribution board 32, and the electrical wiring 53 is connected to the emergency outlet 15. The changeover switch 26 is normally in the A position, and the electric wiring 51 and the electric wiring 52 are connected to each other. In this case, electric power can be supplied from the fuel cell device 20 to the distribution board 32. The circuit to the distribution board 32 is referred to as a normal time circuit.

When the changeover switch 26 is set to the B position, the electric wiring 51 and the electric wiring 53 are connected, the power supply from the fuel cell device 20 to the distribution board 32 is stopped, and the fuel cell device 20 is connected to the emergency outlet 15. And power is supplied. Here, a changeover switch 27 is provided in the middle of the electric wiring 53, and when the changeover switch 27 is set to the C position, the electric wiring 53 is connected to the electric wiring 54, and the guide light is connected from the fuel cell device 20. Power is supplied to 18. The circuit that supplies electric power to the emergency outlet 15 and the guide light 18 is referred to as an emergency circuit 1. When the changeover switch 27 is set to the D position, the power supply to the electric wiring 54 (that is, the guide light 18) is stopped, and the power is supplied only to the emergency outlet 15. A circuit that supplies electric power only to the emergency outlet 15 is referred to as an emergency circuit 2.

The supply of electric power from the fuel cell device 20 by the normal circuit, that is, the supply of electric power from the commercial power supply 31 and the fuel cell device 20 via the distribution board 32 is called grid interconnection operation, and is called emergency operation. The supply of electric power from the fuel cell device 20 by the circuit 1 and the emergency circuit 2 is referred to as self-sustaining operation. The remote controller 23 is provided with a battery (not shown), and in the event of a power failure, the remote controller 23 operates using the power of the battery. The battery may be a dry battery or a secondary battery such as a lithium secondary battery. If it is a secondary battery, for example, it can be charged while being operated by power supply from the distribution board 32 (via the electric wiring from the distribution board 32 to the living room 12) at normal times.

A distribution board 32 is connected to the controller 22, and the controller 22 receives a signal related to electric power from the distribution board 32. Thereby, for example, when the power supplied from the commercial power supply 31 becomes 0, it can be detected that the commercial power supply 31 is in a power failure state.

The changeover switch 26 and the changeover switch 27 are connected to the controller 22. The changeover switch 26 is controlled by the controller 22 to change the connection state (A position or B position) between the electric wiring 51 and the electric wirings 52 and 53. The changeover switch 27 is controlled by the controller 22 to change the connection state (C position or D position) between the electric wiring 53 and the electric wiring 54.

A power meter 17 is connected to the controller 22. The plug provided in the electric device is inserted into the insertion port 17a provided in the power meter 17, and the electric device is activated, so that power is supplied from the emergency outlet 15. That is, since the electric power is supplied through the electric power meter 17, the electric power consumption by the electric device is detected by the electric power meter 17. The detection result is input to the controller 22.

Next, the processing of the self-sustained operation system executed by the controller 22 will be described with reference to the flowchart of FIG. In the building 10, power generation is always performed by the fuel cell device 20, and the flowchart of FIG. 2 is based on the premise that power generation is performed by the fuel cell device 20.

In step S11, it is determined whether or not a power failure has been detected. If a power failure is detected via the distribution board 32, a YES determination is made and the process proceeds to step S12. If a power failure is not detected (that is, the power supply from the commercial power supply 31 is not stopped), a NO determination is made and the present process is terminated.

In step S12, the display unit 23b notifies that a power failure has occurred. Specifically, in the display unit 23b, the light intensity of the backlight 23d is increased to make the display unit 23b emit strong light. Then, a sentence or a picture prompting the switch to the independent operation is displayed on the display unit 23b.

Here, when a power failure is detected, the display unit 23b emits strong light, so that the remote controller 23 of the fuel cell system (in other words, the switch 23c for switching the fuel cell device 20 to independent operation) is arranged there. It is easy to identify that it is. Therefore, even if the resident does not remember the location of the switch 23c of the fuel cell device 20, the remote controller 23 (display unit 23b) provided in the living room 12 can be easily reached by using the light emission as a mark. Then, the resident sees that the display unit 23b indicates that the switch 23c is to be operated in order to switch to the independent operation, and operates the switch 23c arranged in the vicinity of the display unit 23b to become independent. You can switch to driving. That is, even if the operation for using the electric power of the fuel cell device 20 is not grasped in detail, it is possible to easily switch to the independent operation by being guided by the light emission of the display unit 23b and the display content.

In the following step S13, it is determined whether or not the operation for switching to the independent operation has been performed. If the switch to the independent operation is switched by pressing the switch 23c, a YES determination is made and the process proceeds to step S14. If the switch 23c has not been pressed, that is, if the switch to the independent operation has not been performed, a NO determination is made and the process proceeds to step S25.

If the operation for switching to the independent operation has not been performed, in step S25, it is determined whether or not the power failure has been restored. The recovery from the power failure is determined by whether or not the restart of the power supply from the commercial power supply 31 is detected via the distribution board 32. If the power failure has not been restored, a NO determination is made, the process returns to step S13, and each process is repeated. When the power failure is restored, a YES determination is made and the process proceeds to step S26.

In step S26, the display unit 23b notifies that the power failure has been restored. For example, the subsection "The power failure has been restored" is displayed on the display unit 23b. At this time, the light intensity of the backlight 23d of the display unit 23b is not changed, and the display unit 23b is made to emit light strongly. After notifying the recovery of the power failure by the display on the display unit 23b for 1 minute (timed by the timer 22c), the process proceeds to step S23.

In step S23, the light intensity of the backlight 23d of the display unit 23b is lowered to bring the emission luminance of the display unit 23b to the normal state, and the display on the display unit 23b is returned to the normal display (for example, the time is displayed). End the process.

Here, when notifying the recovery of the power failure in step S26, the switch to the independent operation is not performed because it is the result of the NO determination in step S13. Therefore, the grid interconnection operation is resumed immediately after the power failure is restored, and power is supplied to the inside of the building 10 as usual.

When the operation for switching to the independent operation is performed in step S13, in step S14, the changeover switch 26 is switched from the A position to the B position and the changeover switch 27 is changed to C based on the changeover operation to the independent operation. Switch to the position and energize the emergency circuit 1. As a result, the fuel cell device 20 energizes the emergency outlet 15 and the guide light 18 (step S14). The guide light 18 is turned on when the power is turned on. Therefore, the guide light 18 is automatically turned on by switching to the emergency circuit 1. Since the emergency outlet 15 is energized when the circuit is switched to the emergency circuit 1, the lamp 16 provided in the emergency outlet 15 is also automatically lit. In the following step S15, the installation location of the emergency outlet 15 is displayed on the display unit 23b. Here, the room in which the emergency outlet 15 is installed may be displayed, for example, "the emergency outlet is in the living room 11".

By steps S14 and S15, the installation location (room) of the emergency outlet 15 is displayed on the display unit 23b, and in the living room 11 where the emergency outlet 15 is installed, the guide light 18 lights up in the vicinity of the emergency outlet 15. is doing. As a result, the resident grasps the room (living room 11) in which the emergency outlet 15 is installed by the display of the display unit 23b after performing the switching operation to the independent operation in the living room 12, and promptly moves to the living room 11. can. Then, the resident who has moved to the living room 11 can immediately find the emergency outlet 15 by turning on the guide light 18.

In the following step S16, it is determined whether or not the emergency outlet 15 has been used. When the power consumption is detected by the power meter 17, it is determined that the emergency outlet 15 has been used, and the process proceeds to step S17. If the power consumption is not detected by the power meter 17, NO is determined as the emergency outlet 15 is not used, and the process proceeds to step S24.

In step S24, it is determined whether or not the power failure has been restored. If the power failure has not been restored, a NO determination is made, the process returns to step S16, and each process is repeated. When the power failure is restored, a YES determination is made and the process proceeds to step S20.

When the emergency outlet 15 is used in step S16, in step S17, the changeover switch 27 is switched from the C position to the D position to cut off the energization to the electric wiring 54 (emergency circuit 2). As a result, the energization of the guide light 18 is stopped, and the guide light 18 is turned off (step S17). When the use of the emergency outlet 15 is detected, the resident knows the position of the emergency outlet 15, so that there is no inconvenience even if the guide light 18 is turned off, and by turning it off, the limit of independent operation is limited. You can save the power saved. Then, in the following step S18, the light intensity of the backlight 23d in the display unit 23b is lowered to set the display unit 23b (display) to the normal emission brightness, and the display of the installation location of the emergency outlet 15 is hidden. This can save the consumption of the battery provided in the remote controller 23.

In the following step S19, it is determined whether or not the power failure has been restored. If the power failure has not been restored, a NO determination is made, the process returns to step S19, and the process is repeated until the power failure is restored. When the power failure is restored, a YES determination is made and the process proceeds to step S20.

When the power failure is restored in steps S19 and S24, in step S20, the display unit 23b notifies that the power failure has been restored. Specifically, in the display unit 23b, the light intensity of the backlight 23d is increased to make the display unit 23b emit strong light. Then, a sentence or an image prompting the switch to the grid interconnection operation is displayed on the display unit 23b. When the process proceeds from step S24 to step S20, the display unit 23b is in a state of strongly emitting light, so that the backlight 23d does not have to be changed.

In the following step S21, it is determined whether or not the switching operation to the grid interconnection operation has been performed. If the switch 23c is pressed to switch to the grid interconnection operation, a YES determination is made and the process proceeds to step S22. If the switch 23c has not been pressed, that is, if the switch to the grid interconnection operation has not been performed, a NO determination is made and the process returns to step S21, and the process is repeated until the switch to the grid interconnection operation is performed. ..

When the switching operation to the grid interconnection operation is performed, in step S22, the changeover switch 26 is switched from the B position to the A position based on the switching operation to the grid interconnection operation, and the normal circuit. Energize. As a result, the fuel cell device 20 energizes the distribution board 32. Here, if the process proceeds from step S24 to step S22, the power supply between the emergency outlet 15 and the guide light 18 is cut off, and if the process proceeds to step S22 via steps S17 and S18, the emergency outlet 15 The power supply to the power supply will be cut off.

After switching to the grid interconnection operation, the process proceeds to step S23, the light intensity of the backlight 23d of the display unit 23b is lowered to set the emission brightness of the display unit 23b to the normal state, and the display on the display unit 23b is normally displayed (for example, time). Is displayed), and then this process ends.

According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

According to the present embodiment, in the event of a power failure, the normal circuit can be switched to the emergency circuit 1 by operating the switch 23c, and the operation can be switched to the independent operation. Then, when switching to independent operation, power is supplied to the emergency outlet 15 and the guide light 18, and the guide light 18 automatically lights up near the emergency outlet 15 and resides in the place where the emergency outlet 15 is installed. To guide the person. That is, the guide light 18 serves as a position index for finding the emergency outlet 15. For example, even a resident who has forgotten where to install the emergency outlet 15 can immediately determine whether or not there is an emergency outlet 15 in each room just by looking over the rooms 11 and 12 from the entrance. You can easily reach the emergency outlet 15.

According to the present embodiment, in the event of a power failure, the light intensity of the backlight 23d of the display unit 23b is automatically increased, the emission brightness of the display unit 23b (display) is increased, and the display unit 23b emits light. As a result, the resident can quickly reach the switch 23c using the light emission as an index, and can quickly switch to the independent operation.

According to this embodiment, when a power failure occurs, the location of the emergency outlet 15 is automatically displayed on the display unit 23b. As a result, the resident can confirm the installation location of the emergency outlet 15 on the display of the display unit 23b when switching to the independent operation, and can accurately grasp the installation location. Therefore, it is not necessary to look around a plurality of rooms in order to search for the emergency outlet 15, and the room 11 in which the emergency outlet 15 is installed can be quickly reached. That is, it is possible to guide the user to the room where the emergency outlet 15 is installed, and to reach the emergency outlet 15 more quickly in an emergency.

According to the present embodiment, when the power meter 17 detects that the power supply to the device is started from the emergency outlet 15, the guide light 18 is turned off. If the emergency outlet 15 is in use, the resident already knows the location of the emergency outlet 15. Therefore, there is no inconvenience even if the guide light 18 is turned off, and by turning off the guide light 18, it is possible to save the limited electric power of the independent operation.

The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

(1) In the above embodiment, emergency power is supplied by a fuel cell as a distributed power source, but as a distributed power source, a power generation device capable of generating power using natural energy and power can be charged and discharged. It may be a power storage device, or a combination of these may be used. For example, a photovoltaic power generation system, a storage battery system, a fuel cell system equipped with a storage battery, a power feeding device system such as a photovoltaic power generation system equipped with a storage battery, and the like can be used as a distributed power source.

In the case of a storage battery system, electric power is supplied to the storage battery from the commercial power source 31 at night or the like, and the storage battery stores the electric power (in this case, a transmission line or electricity for supplying electric power from the distribution board 32 or the commercial power source 31 to the storage battery. Wiring is required). Then, the stored electric power can be used in the daytime or during independent operation. In this case, the self-sustained operation can be carried out in the same manner as the fuel cell device 20 of the above embodiment except that the fuel cell device 20 is replaced with the storage battery device.

In the case of a photovoltaic power generation system, instead of the fuel cell device 20, the photovoltaic panel (outdoor side of the building 10 (for example, roof, etc.)) and the power condition that converts the DC power generated by the photovoltaic panel into AC power. Set up with a solar panel. The power conditioner is connected to the electrical wiring 51. The power conditioner has a controller function to control solar power generation. When solar power generation is performed, the self-sustained operation can be carried out in the same manner as the fuel cell device 20 of the above embodiment except for the above configuration.

A storage battery is required to operate independently in a situation where photovoltaic power generation is not performed in the photovoltaic power generation system. In this case, for example, the power conditioner may be connected to the storage battery and the storage battery may be connected to the electric wiring 51, but the connection form between the storage battery and the power conditioner and the connection form between the electric wiring 51 are limited to this. Not done.

(2) In the above embodiment, the use of the emergency outlet 15 is detected by the power meter 17 inserted into the outlet 15a of the emergency outlet 15. For example, the emergency outlet 15 and the fuel cell device 20 are used. A power meter may be installed at any location of the electrical wiring between them (for example, the electrical wiring 51, 53 which is the emergency circuit 2). In this case, a power meter that can measure power by connecting to the wiring is used. For example, when a power meter is arranged in the electric wiring 51 and the power consumption when the electric wiring 51 is energized becomes higher than a predetermined value (for example, the power consumption of the guide light 18 or more), the emergency outlet 15 May be determined to have been used.

(3) In the above embodiment, only one emergency outlet 15 is installed, but a plurality of emergency outlets 15 may be installed. In that case, the guide light 18 may be provided in each emergency outlet 15. If a power meter 17 is installed in each emergency outlet 15, the lighting or extinguishing of each guide light 18 can be controlled according to each use. In this case, the display of the location of the emergency outlet 15 on the display unit 23b may be displayed or hidden in correspondence with the extinguishing of each guide light 18, and all the emergency outlets 15 are used (all guides). After the light 18 is turned off), it may be hidden all at once.

(4) In the above embodiment, the operation of switching to the independent operation is performed by pressing the switch 23c provided on the operation unit 23a. For example, the display unit 23b is used as a touch panel display, and the command displayed on the display is used. It may be configured to switch to independent operation by touching.

(5) In the above embodiment, the light intensity of the backlight 23d of the display unit 23b is lowered after the use of the emergency outlet 15 is confirmed. However, for example, the backlight 23d is switched to the independent operation at the same time. The light intensity may be lowered. As a result, the battery provided in the remote controller 23 can be saved while ensuring the effect of guiding the resident to the operation unit 23a in the event of a power failure.

(6) In the above embodiment, the display unit 23b is made to emit light by adjusting the light intensity of the backlight 23d of the display unit 23b, but the light emitting means is not limited to this. For example, the light emitting means may be a lamp such as an LED, and in this case, a red lamp may be turned on in an emergency.

(7) In the above embodiment, only one guide light 18 is provided near the emergency outlet 15, but for example, a plurality of guide lights are provided on the route from the remote controller 23 to the installation location (room) of the emergency outlet 15. 18 may be installed. For example, when the living room 11 and the living room 12 are set to be able to come and go through the corridor, the guide light 18 is provided in the corridor near the corridor, and the guide light 18 is provided in the corridor on the side facing the living room 11. Further, a guide light 18 is provided at a position close to the emergency outlet 15 in the living room 11. As a result, the user is guided to the installation location of the emergency outlet 15 simply by following the guide light 18, and can easily reach the emergency outlet 15.

(8) In the above embodiment, the guide light 18 is provided separately from the lighting used in the normal time, but the lighting used in the normal time may be the guide light 18. In this case, the guide light 18 has not only the emergency circuit 1 but also the normal circuit as the power supply circuit. For example, as shown in FIG. 3, the guide light 18 is connected from the distribution board 32 to the switch 28 via the electric wiring 43. The switch 28 is a switch operated by a resident when used as lighting in normal times. When the switch 28 is turned on, the electrical wiring 43 is connected to the electrical wiring 44, and the electrical wiring 44 is connected to the switch 29.

The switch 29 is a switch for switching whether the power supply destination to the guide light 18 is the distribution board 32 or the fuel cell device 20. That is, when the switch 29 is set to the G position, the electric wirings 43 and 44 and the electric wiring 54 are connected, and power is supplied from the distribution board 32 to the guide light 18. In this case, the light of the guide light 18 can be turned on and off by the switch 28, and the guide light 18 can be used as lighting in a normal time. When the switch 29 is set to the H position, the electric wiring 54 and the electric wiring 53 are connected, and electric power is supplied from the fuel cell device 20 to the guide light 18. Since the switch 28 is provided between the distribution board 32 and the switch 29 instead of the path of the electric wirings 53 and 54, the on / off of the switch 28 does not affect the emergency circuit 1. As a result, the guide light 18 can be turned on in the event of a power failure.

Even when the lighting used in normal times is the guide light 18, a plurality of lights used in normal times existing in the route from the remote controller 23 to the installation location (room) of the emergency outlet 15 may be used as the guide lights 18.
