Description

  The present invention relates to a control device, a control method, and a program for controlling an electric device.

  In general, electric devices used in homes or the like are supplied with electric power from a commercial power source via a breaker. This breaker cuts off the supply of electric power when the total value of electric power supplied to the electrical equipment exceeds a predetermined threshold value. When the supply of power is interrupted by the breaker, the operation of the electric device is stopped and inconveniences often occur. For this reason, various techniques are known for controlling an electric device so that the total value of the electric power supplied to the electric device via the breaker does not exceed a threshold value.

  For example, Patent Document 1 discloses a total power consumption calculation unit that calculates the total power consumption of each electrical device, and a cooperative operation that issues an instruction to change the operation state of each electrical device when the total power consumption exceeds the allowable power consumption. A power management device including a control unit is disclosed. Here, the allowable power consumption is set as a target of the power consumption of the entire house.

JP 2014-36466 A

  However, the power management device disclosed in Patent Document 1 is a device that manages the power consumption of the entire house, and a device that manages the power consumption for each of the L1 phase and the L2 phase in a single-phase three-wire power supply system. It wasn't. For this reason, when the power management apparatus disclosed in Patent Document 1 is applied to a power supply system in which a threshold value of power that can be supplied is determined for each phase, for example, the power consumption of the entire house is set for each phase. Management is performed so as not to exceed the threshold value, and power consumption is excessively suppressed. Accordingly, there is a demand for a technique for efficiently suppressing the power consumption of an electric device by managing the power consumption for each phase.

  An object of this invention is to provide the control apparatus, the control method, and program which suppress the power consumption of an electric equipment efficiently.

In order to achieve the above object, a control device according to the present invention provides:
A first power value that is a total value of power supplied to a plurality of electrical devices including the first device from which the value of surplus power from the current power consumption to the upper limit of power consumption is acquired from the L1 phase; and L2 A power value acquisition unit that acquires a second power value that is a total value of power supplied from the phase to the plurality of electrical devices;
When the first power value acquired by the power value acquisition unit is less than the first threshold, the power consumption value of the first device is supplied from the L2 phase of the surplus power of the first device. The upper limit value of power consumption is not exceeded so that the first total value, which is the sum of the value of the surplus power and the first power value that is not clear, is less than or equal to the second threshold value that is smaller than the first threshold value. When one device is controlled and the second power value acquired by the power value acquisition unit is less than the first threshold, the power consumption value of the first device is the surplus power of the first device. The upper limit value of power consumption that does not exceed the second threshold value is set to a second total value that is a total value of the surplus power value that is not clearly supplied from the L1 phase and the second power value. A control unit that controls the first device.

  In the present invention, when the first power value is less than the first threshold value, the value of the power consumption upper limit value that causes the power consumption value of the first device to be equal to or less than the second threshold value that is smaller than the first threshold value. When the first device is controlled so as not to exceed the value and the second power value is less than the first threshold value, the power consumption value of the first device causes the second total value to be less than or equal to the second threshold value. The first device is controlled so as not to exceed the value of. Therefore, according to this invention, the power consumption of an electric equipment can be suppressed efficiently.

Therefore, a device connected to the home network 710 and a device connected to the outside network 720 can communicate with each other. The outside network 720 is, for example, a WAN (Wide Area Network) such as the Internet.

  Next, basic functions of the control device 100 will be described with reference to FIG. Functionally, the control device 100 includes a power value acquisition unit 101, a control unit 103 including an upper limit value setting unit 102, a phase determination unit 104, a reception unit 105, and an individual power information acquisition unit 106.

  The power value acquisition unit 101 acquires a first power value and a second power value. The first power value is a total value of power supplied from the L1 phase to a plurality of electric devices including the first device. The second power value is a total value of the power supplied from the L2 phase to the plurality of electric devices. The function of the power value acquisition unit 101 is realized by the cooperation of the CPU 11 and the network interface 17, for example.

  When the first power value is less than the first threshold, the upper limit setting unit 102 sets the upper limit value of the power consumption of the first device so that the first total value is less than or equal to the second threshold. The second threshold is a threshold smaller than the first threshold. The second threshold value is a threshold value that is normally used in a low output process. The first threshold value is a threshold value for determining whether or not an emergency low output process is necessary. For example, the first threshold is set to a value smaller than the breaker capacity. The first total value is a total value of the surplus power value related to the L1 phase and the first power value. The surplus power value related to the L1 phase is a total value of the surplus power that is not determined to be supplied from the L2 phase among the surplus power of the first device. The surplus power value related to the L1 phase is the total value of the surplus power of the first device whose connection destination phase is known to be only the L1 phase, and the connection destination phase is the L1 phase and the L2 phase. Is the sum of the half value of the total value of the remaining power of the first device and the total value of the remaining power of the first device whose connection destination phase is unknown. That is, the surplus power value related to the L1 phase is calculated in consideration of the surplus power that may be supplied from the L1 phase and consumed. It is desirable that the upper limit setting unit 102 sets the upper limit value of the power consumption of the first device as high as possible as long as the first total value is equal to or less than the second threshold value.

  Further, when the second power value is less than the first threshold value, the upper limit value setting unit 102 sets the upper limit value of the power consumption of the first device so that the second total value is equal to or less than the second threshold value. The second total value is a total value of the surplus power value related to the L2 phase and the second power value. The surplus power value related to the L2 phase is a total value of the surplus power that cannot be determined from being supplied from the L1 phase among the surplus power of the first device. The surplus power value related to the L2 phase is the total value of the surplus power of the first device whose connection destination phase is known to be only the L2 phase, and the connection destination phases are the L1 phase and the L2 phase. Is the sum of the half value of the total value of the remaining power of the first device and the total value of the remaining power of the first device whose connection destination phase is unknown. That is, the surplus power value related to the L2 phase is calculated in consideration of the surplus power that may be supplied from the L2 phase and consumed. The upper limit setting unit 102 desirably sets the upper limit value of the power consumption of the first device as high as possible as long as the second total value is equal to or less than the second threshold value. The function of the upper limit setting unit 102 is realized by the cooperation of the CPU 11 and the network interface 17, for example.

  The control unit 103 controls the first device so that the power consumption value of the first device does not exceed the upper limit value set by the upper limit value setting unit 102. For example, the control unit 103 transmits a control signal instructing to operate with power consumption less than a set upper limit value (saving power) to the first device. The first device saves power in response to receiving such a control signal, and then ends the power saving when a predetermined time (for example, several tens of minutes) has elapsed. May be. With such a configuration, the first device can automatically shift to a state in which power is not saved even if the control device 100 does not send or receive a control signal instructing to cancel power saving. The function of the control unit 103 is realized, for example, by the cooperation of the CPU 11 and the network interface 17.

  When the first power value acquired by the power value acquisition unit 101 changes in response to the control of the first device by the control unit 103, the phase determination unit 104 determines that the remaining power of the first device is from the L1 phase. It can be determined that it is supplied. Further, when the second power value acquired by the power value acquisition unit 101 changes in response to the control of the first device by the control unit 103, the phase determination unit 104 determines that the remaining power of the first device is L2. It can be determined that it is supplied from the phase. Further, the phase determination unit 104 determines that the first device when the first power value and the second power value acquired by the power value acquisition unit 101 change in response to the control of the first device by the control unit 103. It is possible to determine that the remaining power is supplied from both the L1 phase and the L2 phase. It is assumed that the control unit 103 controls the first device so that the power consumption of the first device changes. The function of the phase determination unit 104 is realized, for example, when the CPU 11 executes a program stored in the ROM 12.

  Here, the upper limit value setting unit 102 sets the upper limit value of the power consumption with respect to the maximum rated value of the power consumption when setting the upper limit value of the power consumption of the plurality of first devices supplied with the surplus power from the same phase. The upper limit value of the power consumption of the plurality of first devices may be set so that the ratio of is constant.

  Alternatively, the upper limit setting unit 102 may add the first device that is the target of the low output process in a stepwise manner. For example, when the first power value acquired by the power value acquisition unit 101 is less than the first threshold and the second device is a device related to the L1 phase, the upper limit value setting unit 102 is the first device that is not the second device. The upper limit value of the power consumption of the equipment related to the L1 phase is set. The case where the second device is a device related to the L1 phase is, for example, a case where it is not determined that the surplus power of the second device is supplied only from the L2 phase. In addition, the device related to the L1 phase among the first devices that are not the second devices is, for example, the first device that is not determined that the surplus power is supplied only from the L2 phase among the first devices that are not the second devices. Here, the upper limit setting unit 102 further sets an upper limit value of the power consumption of the second device when the first total value does not become the second threshold value or less.

  The upper limit value setting unit 102 is a first device that is not the second device when the second power value acquired by the power value acquiring unit 101 is less than the first threshold and the second device is a device related to the L2 phase. The upper limit value of the power consumption of the device related to the L2 phase is set. The case where the second device is a device related to the L2 phase is, for example, a case where it is not determined that the surplus power of the second device is supplied only from the L1 phase. In addition, the device related to the L2 phase among the first devices that are not the second devices is, for example, the first device that is not determined that the surplus power is supplied only from the L1 phase among the first devices that are not the second devices. Here, the upper limit setting unit 102 further sets an upper limit value of the power consumption of the second device when the second total value does not become the second threshold value or less.

  The receiving unit 105 receives an activation signal indicating that the second device is being activated. The function of the receiving unit 105 is realized by the function of the network interface 17, for example. Here, the upper limit value setting unit 102 is not determined that the first power value acquired by the power value acquiring unit 101 is less than the first threshold value and the power consumed by the second device is supplied only from the L2 phase. When the activation signal is received by the receiving unit 105, the maximum upper limit value of power consumption is set as the upper limit value of power consumption of the second device. Then, the upper limit setting unit 102 sets an upper limit value of the power consumption of the first device related to the L1 phase among the first devices that are not the second devices so that the first total value is equal to or less than the second threshold value.

  Further, the upper limit value setting unit 102 does not determine that the second power value acquired by the power value acquiring unit 101 is less than the first threshold value, and that the surplus power of the second device is supplied only from the L2 phase. When the activation signal is received by the unit 105, the upper limit value of the power consumption is set as the upper limit value of the power consumption of the second device. Then, the upper limit setting unit 102 sets the upper limit value of the power consumption of the first device related to the L2 phase among the first devices that are not the second devices, so that the second total value is equal to or less than the second threshold value.

  Here, when the first power value acquired by the power value acquisition unit 101 is greater than or equal to the first threshold value, the upper limit value setting unit 102 determines that surplus power is supplied from only the L2 phase among the plurality of electrical devices. You may set the minimum value of the upper limit of power consumption as a value of the upper limit of power consumption of all the electric devices which are not performed.

  Further, when the second power value acquired by the power value acquisition unit 101 is equal to or greater than the first threshold value, the upper limit value setting unit 102 is not determined that surplus power is supplied from only the L1 phase among the plurality of electrical devices. You may set the minimum value of the upper limit of power consumption as a value of the upper limit of power consumption of all the electric devices.

  The individual power information acquisition unit 106 acquires individual power information from the first electric device. As described above, the individual power information is information indicating the current power consumption value, the upper limit value of power consumption, and the maximum rated value of power consumption. The function of the individual power information acquisition unit 106 is realized by the cooperation of the CPU 11 and the network interface 17, for example.

  Next, with reference to FIG. 4, a method for reducing the output of the first device related to the L1 phase will be described.

  First, the first total value is a total value of the first power value and the first surplus power value. In the present embodiment, the electrical devices that are supplied with power from the L1 phase are three electrical devices, that is, the electrical device 401, the electrical device 402, and the electrical device 403. Here, the electric equipment 401 is supplied with the same amount of power from the L2 phase as the amount of power supplied from the L1 phase. That is, 50% of the power consumption value of the electric device 401 is taken into account when calculating the first power consumption value. Therefore, the first power value is a total value of 50% of the power consumption value of the electric device 401, the power consumption value of the electric device 402, and the power consumption value of the electric device 403.

  Here, since the electrical device 403 is not the first device, the control device 100 cannot specify the power consumption value or the surplus power value of the electrical device 403. For this reason, the power consumption value of the electric device 403 is indicated by a broken line. Further, the surplus power value of the electric device 403 is not taken into account when calculating the first surplus power value. On the other hand, since the electric device 404 is a device whose connection destination cannot be specified, the control device 100 cannot specify whether or not the electric device 404 is connected to the L1 phase. For this reason, the surplus power value of the electrical device 404 is taken into account when calculating the first surplus power value. That is, the first surplus power value is a total value of 50% of the surplus power value of the electrical device 401, the surplus power value of the electrical device 402, and the surplus power value of the electrical device 404.

  Here, as shown in FIG. 4, it is assumed that the first power value before output reduction is less than the first threshold value, and the first total value before output reduction exceeds the second threshold value. In this case, the control device 100 reduces the upper limit value of the power consumption of the first device related to the L1 phase so that the first total value is equal to or less than the second threshold value. For example, the control device 100 sets the upper limit value of power consumption of the electric device 401, the upper limit value of power consumption of the electric device 402, and the upper limit value of power consumption of the electric device 404 until the first total value becomes equal to or less than the second threshold value. Gradually decrease. FIG. 4 shows an example in which the first total value before the output is lowered to the second threshold value.

  Next, with reference to FIG. 5, a method for reducing the output of the first device related to the L2 phase will be described.

  First, the second total value is a total value of the second power value and the second surplus power value. In the present embodiment, the electrical devices that receive power supply from the L2 phase are the three electrical devices of the electrical device 401, the electrical device 404, and the electrical device 405. Here, 50% of the power consumption value of the electrical device 401 is taken into account when calculating the second surplus power value. Therefore, the second power value is a total value of 50% of the power consumption value of the electric device 401, the power consumption value of the electric device 404, and the power consumption value of the electric device 405.

  Here, since the electric device 405 is not a controllable device, the control device 100 cannot specify the power consumption value and the remaining power value of the electric device 405. For this reason, the power consumption value of the electric device 405 is indicated by a broken line. Further, the surplus power value of the electric device 405 is not taken into account when calculating the second surplus power value. In addition, since the electrical device 404 is a device whose connection destination cannot be specified, the control device 100 cannot specify whether or not the electrical device 404 is connected to the L2 phase. For this reason, the surplus power value of the electrical device 404 is taken into account when calculating the second surplus power value. That is, the second remaining power value is a total value of 50% of the remaining power value of the electric device 401 and the remaining power value of the electric device 404.

  Here, as shown in FIG. 5, it is assumed that the second power value before output reduction is less than the first threshold value, and the first total value before output reduction exceeds the second threshold value. In this case, the control device 100 reduces the upper limit value of the power consumption of the first device related to the L2 phase so that the first total value is equal to or less than the second threshold value. For example, the control device 100 gradually decreases the upper limit value of the power consumption of the electric device 401 and the upper limit value of the power consumption of the electric device 404 until the second total value becomes equal to or less than the second threshold value. FIG. 5 shows an example in which the second total value before the output is lowered to the second threshold value.

  Next, with reference to FIG. 6, a method of reducing the output of the plurality of first devices related to the L1 phase at the same rate will be described. This method is preferably employed when, for example, the difference in the necessity of maintaining power consumption is relatively small between the first device that is the second device and the first device that is not the second device.

  As illustrated in FIG. 6, the total value of the upper limit values of power consumption of the first device related to the L1 phase is set as the first total upper limit value. Here, the upper limit value of power consumption is the total value of the power consumption value and the surplus power value. Therefore, the first total upper limit value is a total value of the total value of the power consumption values of the first device related to the L1 phase and the total value of the remaining power value of the first device related to the L1 phase. Here, as shown in FIG. 6, it is assumed that the first power value before the output reduction is less than the first threshold value, and the first total value before the output reduction exceeds the second threshold value. In this case, the control device 100 reduces the upper limit value of the power consumption of the first device related to the L1 phase so that the first total value is equal to or less than the second threshold value.

  Specifically, the control device 100 determines that the ratio of the upper limit value of power consumption to the maximum rated value of power consumption is the electric device 401, the electric device 402, and the electric device 404 until the first total value becomes equal to or less than the second threshold value. This ratio is gradually reduced while maintaining the same state. That is, the control device 100 determines the ratio of the upper limit value of power consumption of the electric device 401 to the maximum rated value of power consumption of the electric device 401 and the upper limit of power consumption of the electric device 402 with respect to the maximum rated value of power consumption of the electric device 402. While maintaining the state in which the ratio of the value and the ratio of the upper limit value of the power consumption of the electric device 404 to the maximum rated value of the power consumption of the electric device 404 are the same, this ratio is gradually decreased.

  Next, with reference to FIG. 7, a method for reducing the output of the second device after the output of the first device other than the second device is reduced in the L1 phase will be described. This technique is employed when, for example, the necessity of maintaining power consumption in the first device that is the second device is relatively higher than the necessity of maintaining power consumption in the first device that is not the second device. Is preferable.

  First, as shown in FIG. 7, it is assumed that the first power value before output reduction is less than the first threshold value, and the first total value before output reduction exceeds the second threshold value. In this case, the control device 100 decreases the first total upper limit value so that the first total value is equal to or less than the second threshold value. Specifically, the control device 100 first executes a first-stage output reduction process. The first-stage output reduction process is a process of gradually lowering the upper limit values of the power consumption of the electric device 402 and the electric device 404, which are the first devices that are not the second devices. Here, when the first total value is equal to or lower than the second threshold value in the first stage of lowering the output, the control device 100 completes the lowering of the output process.

  On the other hand, when the first total value does not fall below the second threshold value in the first stage of lowering the output (when the ratio reaches the lower limit value), the control device 100 performs the second stage of lowering the output. Run. The second-stage output reduction process is a process of gradually lowering the upper limit value of power consumption of the electric device 401 as the second device. The control device 100 executes the second-stage output reduction process until the first total value becomes equal to or smaller than the second threshold value or until the ratio in the electric device 401 reaches the lower limit value.

  Next, with reference to FIG. 8, a description will be given of a method in which only the first device other than the second device has a low output in the L1 phase. This technique is employed when, for example, the necessity of maintaining power consumption in the first device that is the second device is much higher than the necessity of maintaining power consumption in the first device that is not the second device. Is preferred.

  First, as shown in FIG. 8, it is assumed that the first power value before output reduction is less than the first threshold value, and the first total value before output reduction exceeds the second threshold value. In this case, the control device 100 decreases the first total upper limit value so that the first total value is equal to or less than the second threshold value. Specifically, the control device 100 gradually lowers the upper limit values of power consumption of the electric device 402 and the electric device 404 that are first devices that are not the second devices. Here, the control device 100 completes the output reduction process when the first total value is equal to or less than the second threshold value. In addition, even when the first total value does not become the second threshold value or less, the control device 100 completes the low output process when the ratio in the electric device 402 and the electric device 404 reaches the lower limit value. That is, in this method, the control device 100 does not execute the low output process for the second device.

  Next, with reference to FIG. 9, a method for urgently reducing the output of the electrical equipment related to the L1 phase will be described. This method is preferably employed when, for example, there is a relatively strong desire not to shut down the leakage breaker 200.

  First, as shown in FIG. 9, it is assumed that the first power value before output reduction is equal to or higher than the first threshold value. In this case, the control device 100 quickly decreases the first total upper limit value so that the first power value becomes less than the first threshold value. Specifically, control device 100 sets the upper limit value of the power consumption of all controllable electric devices among the electric devices related to the L1 phase to the lowest settable value. That is, the control device 100 sets the upper limit value of power consumption of the electric device 401 to the lowest settable value, sets the upper limit value of power consumption of the electric device 402 to the lowest settable value, and consumes the electric device 403. The upper limit value of power is set to the lowest settable value, and the upper limit value of power consumption of the electrical device 404 is set to the lowest settable value. According to such a method, even when the first power value before the output reduction is equal to or higher than the first threshold value, it can be expected that the first power value is quickly made less than the first threshold value.

  Next, with reference to the flowchart shown in FIG. 10, the electric equipment control process which the control apparatus 100 performs is demonstrated. The electric device control process is started in response to, for example, the control device 100 being powered on.

  First, the CPU 11 executes a connection destination specifying process (step S101). The connection destination specifying process will be described in detail with reference to the flowchart shown in FIG.

  First, the CPU 11 selects one electrical device (step S201). Specifically, the CPU 11 selects any one of the electric device 401, the electric device 402, the electric device 403, and the electric device 404. CPU11 will acquire a 1st electric power value and a 2nd electric power value, if the process of step S201 is completed (step S202). Specifically, the CPU 11 acquires information indicating the first power value and information indicating the second power value from the measurement device 300 via the network interface 17, and stores the acquired information in the RAM 13.

  CPU11 will change the operation state of the selected electrical equipment, if the process of step S202 is completed (step S203). For example, the CPU 11 transmits a control signal instructing change of the operation state to the selected electrical device via the network interface 17. It is assumed that the power consumption of the selected electrical device changes when the operating state of the selected electrical device is changed.

  CPU11 will acquire a 1st electric power value and a 2nd electric power value, if the process of step S203 is completed (step S204). Specifically, the CPU 11 acquires information indicating the first power value and information indicating the second power value from the measurement device 300 via the network interface 17, and stores the acquired information in the RAM 13. When completing the process of step S204, the CPU 11 determines whether or not both the first power value and the second power value have changed before and after the change of the operation state (step S205).

  If CPU11 discriminate | determines that both the 1st electric power value and the 2nd electric power value changed (step S205: YES), the connection destination of the selected electric equipment will be specified as L1 phase and L2 phase (step S206). When determining that both the first power value and the second power value have not changed (step S205: NO), the CPU 11 determines whether or not the first power value has changed before and after the change of the operating state. (Step S207).

  When determining that the first power value has changed (step S207: YES), the CPU 11 specifies the connection destination of the selected electrical device as the L1 phase (step S208). On the other hand, when determining that the first power value has not changed (step S207: NO), the CPU 11 specifies the connection destination of the selected electrical device as the L2 phase (step S209). CPU11 memorize | stores the specific result in step S206, step S208, and step S209 in RAM13.

  CPU11 will discriminate | determine whether there exists any unselected electric equipment, if the process of step S206, step S208, and step S209 is completed (step S210). If the CPU 11 determines that there is an unselected electrical device (step S210: YES), the CPU 11 returns the process to step S201, and selects one unselected electrical device in step S201. When the CPU 11 determines that there is no unselected electrical device (step S210: NO), the connection destination specifying process is completed.

  When completing the process in step S101, the CPU 11 determines whether or not the current time is the power value check time (step S102). The power value check time is, for example, a time that arrives every time a predetermined time (for example, 30 seconds) elapses. For example, the CPU 11 determines whether or not the current time is the power value check time based on information supplied from the RTC 15. When determining that the current time is not the power value check time (step S102: NO), the CPU 11 returns the process to step S102.

  On the other hand, when determining that the current time is the power value check time (step S102: YES), the CPU 11 obtains the first power value (step S103). Specifically, the CPU 11 acquires information indicating the first power value from the measurement device 300 via the network interface 17. CPU11 will discriminate | determine whether a 1st electric power value is more than a 1st threshold value, if the process of step S103 is completed (step S104).

  If the CPU 11 determines that the first power value is equal to or greater than the first threshold (step S104: YES), the CPU 11 executes a first emergency low output process (step S105). The first emergency low output process is a process for reducing the output by the method described with reference to FIG. That is, in the first emergency output reduction process, the CPU 11 sets the upper limit value of the power consumption of all controllable electric devices among the electric devices related to the L1 phase to the settable minimum value.

  On the other hand, if the CPU 11 determines that the first power value is not equal to or greater than the first threshold (step S104: NO), the CPU 11 executes a first normal output reduction process (step S106). The first normal output reduction process will be described in detail with reference to the flowchart shown in FIG.

  First, the CPU 11 acquires the remaining power value of the first device related to the L1 phase (step S301). For example, the CPU 11 acquires individual power information from all the first devices related to the L1 phase via the network interface 17. Note that the individual power information includes information indicating a surplus power value.

  When completing the process in step S301, the CPU 11 determines whether or not the first total value is equal to or less than the second threshold (step S302). The first total value is the total value of the surplus power value acquired in step S301 and the first power value acquired in step S103. When the CPU 11 determines that the first total value is equal to or less than the second threshold (step S302: YES), the first normal output reduction process is completed.

  On the other hand, when determining that the first total value is not equal to or less than the second threshold value (step S302: NO), the CPU 11 determines whether or not an activation signal has been received from the second device related to the L1 phase (step S303). For example, the CPU 11 determines whether a startup signal is received from the second device related to the L1 phase by the network interface 17.

  When determining that the activation signal is received from the second device related to the L1 phase (step S303: YES), the CPU 11 maximizes the second device related to the L1 phase (step S304). For example, the CPU 11 sets the maximum rated value of power consumption of the second device as the upper limit value of power consumption of the second device related to the L1 phase. And CPU11 transmits the control signal which instruct | indicates making the upper limit of power consumption into this maximum rated value via this network interface 17 to this 2nd apparatus.

  When completing the process in step S304, the CPU 11 lowers the output of the first device (other than the second device) related to the L1 phase (step S305). For example, the CPU 11 executes a process of gradually reducing the upper limit value of power consumption of the first device (other than the second device) related to the L1 phase until the first total value becomes equal to or less than the second threshold value. Note that the processing executed in steps S304 and S305 is a low output reduction process using the method described with reference to FIG. When completing the process of step S305, the CPU 11 completes the first normal output reduction process.

  When the CPU 11 determines that the activation signal is not received from the second device related to the L1 phase (step S303: NO), the CPU 11 reduces the output of the first device related to the L1 phase (other than the second device) (step S306). ). CPU11 will acquire a 1st electric power value, if the process of step S306 is completed (step S307). CPU11 will acquire the surplus electric power value of the 1st apparatus in connection with L1 phase, if the process of step S307 is completed (step S308).

  When completing the process in step S308, the CPU 11 determines whether or not the first total value is equal to or less than the second threshold (step S309). When determining that the first total value is equal to or less than the second threshold (step S309: YES), the CPU 11 completes the first normal output reduction process.

  On the other hand, when determining that the first total value is not equal to or smaller than the second threshold value (step S309: NO), the CPU 11 reduces the output of the second device related to the L1 phase (step S310). For example, the CPU 11 executes a process of gradually reducing the upper limit value of the power consumption of the second device related to the L1 phase until the first total value becomes equal to or less than the second threshold value. Note that the processing executed in steps S306 to S310 is a low-output processing by the method described with reference to FIG. When completing the process of step S310, the CPU 11 completes the first normal output reduction process.

  On the other hand, CPU11 will acquire a 2nd electric power value, if the process of step S105 or step S106 is completed (step S107). Specifically, the CPU 11 acquires information indicating the second power value from the measurement device 300 via the network interface 17. CPU11 will discriminate | determine whether a 2nd electric power value is more than a 1st threshold value, if the process of step S107 is completed (step S108).

  CPU11 performs a 2nd emergency low output process, when it determines with a 2nd electric power value being more than a 1st threshold value (step S108: YES) (step S109). The second emergency low output process is a process for reducing the output by the method described with reference to FIG. The second emergency output reduction process is the same process as the first emergency output reduction process except that the phase targeted for the output reduction process is the L2 phase. That is, in the second emergency low output process, the CPU 11 sets the upper limit value of the power consumption of all controllable electric devices among the electric devices related to the L2 phase to the lowest settable value.

  On the other hand, if the CPU 11 determines that the second power value is not equal to or greater than the first threshold (step S108: NO), the CPU 11 executes a second normal low output process (step S110). The second normal output reduction process is the same process as the first normal output reduction process except that the phase targeted for the output reduction process is the L2 phase. When the CPU 11 completes the process of step S109 or step S110, the process returns to step S102.

  As described above, in the present embodiment, when the first power value is less than the first threshold, the power consumption value of the first device is less than or equal to the second threshold that is smaller than the first threshold. When the first device is controlled so as not to exceed the upper limit value of power consumption to be performed and the second power value is less than the first threshold value, the power consumption value of the first device is set to the second total value as the second threshold value. The first device is controlled so as not to exceed the upper limit value of power consumption to be described below. Thus, in this embodiment, the power consumption of an electric equipment is controlled for every phase of L1 phase and L2 phase. Therefore, according to the present embodiment, the power consumption of the electric device can be efficiently suppressed. In the present embodiment, the first threshold is set lower than the breaker capacity, and the second threshold is set lower than the first threshold. Therefore, according to the present embodiment, it is possible to make it difficult to interrupt the leakage breaker 200.

  Moreover, in this embodiment, the phase from which an electric equipment receives supply of electric power is specified based on the change of a 1st electric power value, and the change of a 2nd electric power value. Therefore, according to the present embodiment, the power consumption of the electric device can be more efficiently suppressed.

  Moreover, in this embodiment, when setting the upper limit value of power consumption of a plurality of first devices supplied with surplus power from the same phase, the ratio of the upper limit value of power consumption to the maximum rated value of power consumption is The upper limit value of the power consumption of the plurality of first devices is set so as to be the same. Therefore, according to this embodiment, the upper limit value of the power consumption of the plurality of first devices can be reduced in a well-balanced manner.

  Further, in the present embodiment, if the reduction in power consumption is insufficient even when the output reduction process for the first device that is not the second device is executed, the output reduction process for the first device that is the second device is executed. Is done. Therefore, according to this embodiment, the upper limit value of the power consumption of the second device can be made difficult to decrease.

  In the present embodiment, the output reduction process is executed for the first device that is not the second device, and the output reduction process is not executed for the first device that is the second device. Therefore, according to this embodiment, it can suppress that the upper limit value of the power consumption of a 2nd apparatus falls.

  Further, in the present embodiment, when the first power value is equal to or greater than the first threshold value and when the second power value is equal to or greater than the first threshold value, the significant low output process is promptly executed. Therefore, according to the present embodiment, it is possible to make it difficult to interrupt the leakage breaker 200.
