FIG. 2 is a block configuration diagram illustrating a functional block inside the server apparatus 102 installed in the power plant 100 and a connection relationship between the functional block and the power generation apparatus 101 and the wireless transmitter 103.
In the server apparatus 102, the receiving unit 50 is connected to the power generation apparatus 101 and receives a power supply value that is output from the power generation apparatus 101 at regular time intervals. The setting input unit 52 inputs a power value that is a control target set in advance in response to an operation of the operator of the power plant 100. Whether the determination unit 51 performs power supply stop control or return control based on the power supply in-supply value of the power generation apparatus 101 received by the reception unit 50 and the control target power value input by the setting input unit 52. And the determination result information of either stop or return is output.

  The detection unit 53 receives the determination result information from the determination unit 51. When the determination result information is stop control, the detection unit 53 detects information on devices such as the electrical appliances 15 and 25 or the power distribution control device 30 that perform the stop, and detects them. The control information including the address information included in the received information and the supply return instruction is output to the wireless transmitter 103. The clock 57 corresponds to the above-described time measuring means, and outputs time information in response to a request.

  For example, the counting unit 55 searches the database 54 every day, detects information on the number of stops for each stopped device, and determines the number of stops for each device based on the detected number of stops and a predetermined discount fee. Calculate discounted charges. The output unit 56 is connected to, for example, a charge server of the power plant 100, and transmits a discount fee for each device output by the totaling unit 55 to the charge server together with device information.

FIG. 3 is a diagram showing a data configuration of the database 54.
The database 54 has a No. indicating the item number. , Entry of supply status, address information, power consumption, device name, installation location, stop start time, stop count. No. In the database 54, a number assigned every time a device to be controlled is registered is recorded in the database 54, and in principle, it is subject to stop control in descending order. In the supply state, “ON” and “OFF” are recorded every time control is performed by the detection unit 53, and the case of “OFF” indicates a controlled object, that is, a state where power supply is stopped. , “ON” indicates a state that is not controlled, that is, power is being supplied.

  In the address information, the address information assigned to the wireless reception units 11, 21, and 31 of the infrared power supply control device 10, the power supply control device 20, and the power distribution control device 30 is recorded in advance. As the address information, for example, an IP (Internet Protocol) address shown in FIG. 3 is applied.

In the case of the electrical appliances 15 and 25, the power consumption is recorded as the power consumed by each device, and in the case of the power distribution control device 30, the value of the total power that can be supplied by the switchboard 34 is recorded in advance. The In the device name, names of devices such as the electrification devices 15 and 25 and the power distribution control device 30 are recorded in advance. In the installation location, a location where each device is installed is recorded in advance. As the stop start time, the time when the stop control is started is recorded by the detection unit 53. The number of times of stop control is recorded by the detection unit 53 every time control is performed.

  Next, power supply control processing in the server apparatus 102 will be described with reference to FIGS. 4 and 5. FIG. 4 is a flowchart showing control processing for stopping and returning power supply in the server apparatus 102. First, the receiving unit 50 of the server apparatus 102 receives a supply power value transmitted from the power generation apparatus 101 at regular time intervals (step Sa1).

  The determination unit 51 performs stop control based on the supplied power value received by the receiving unit 50 and the control target power value input in advance from the setting input unit 52, without performing control. Or whether to perform return control (step Sa2). Then, the determination result information is output to the detection unit 53. Specifically, the power demand curve obtained from the history of the power supply value of the past power generation apparatus 101 shown in FIG. Based on the supply power value, the stop control is performed from the time when the rate of increase exceeds the control target power value within a predetermined time (A in FIG. 5) until it becomes smaller than the control target power value. judge. On the other hand, after the supply power value becomes smaller than the control target power value, it is determined that the return control is performed. In other states, it is determined as a maintenance state in which start and stop control is not performed, and the process of the determination unit 51 returns to step Sa1.

Here, one means of determination when starting the stop control at the position A in FIG. 5 will be described. First, when the supply power value is e (t), the primary differential value M (t _m ) is always measured. M (t _m ) is calculated by the following equation (1).

Next, the supply power value e (t _m + Δt) after the time Δt is predicted. e (t _m + Δt) is calculated by the following equation (2).

It is necessary to perform control so that the supply power value after the time Δt does not exceed the control target value e _T while constantly monitoring the first derivative value: M (t _m ) of the change in the supply power value. That is, the time when the supply power value after Δt becomes the control target value e _T, so that the following equation (3) is satisfied when the control start time was t _s.

From equation (3), the primary differential value of the control start time _{t s:} M _{(t s)} can be expressed as the following formula (4), stop control starts at the time _{t s} which satisfies the equation (4) Will be.
Note that the value of Δt is determined in consideration of a response time from when a supply stop instruction is transmitted by radio signal to each household electrical appliance by wireless communication until the actual stop.

  Next, the detection unit 53 receives the determination result information output from the determination unit 51. When the determination result information is stop control, the detection unit 53 detects a device capable of stopping power supply from the database 54. Specifically, the supply state is referred to, and the supply state “ON” is detected. Next, the detection unit 53 detects the one with the smallest “stop count” among the supply states “ON”, and if there are a plurality of those with the smallest stop count, “No. "Is detected as a control target (step Sa3). Next, the detection unit 53 reads the address information of the device detected as the control target, records the supply state of the control target as “OFF”, increases the stop count by 1, and records it as a new stop count. The database 54 is updated (step Sa4). Then, the detection unit 53 transmits the read address information and control information including a supply stop instruction to the wireless transmitter 103. The wireless transmitter 103 transmits a wireless signal including the control information received from the detection unit 53 via the transmission antenna 104 (step Sa5).

On the other hand, when the determination result information received from the determination unit 51 is the return control, the detection unit 53 refers to the stop start time of the database 54 and detects and detects the device that has been stopped for the longest time. The device address information is read out (step Sa6). Then, the detected supply state of the device is recorded as “ON” and the database 54 is updated (step Sa7). Then, the detection unit 53 transmits the read address information and control information including a supply return instruction to the wireless transmitter 103. The wireless transmitter 103 transmits a wireless signal including control information received from the detection unit 53 via the transmission antenna 104 (step Sa8).
The number of devices to be restored is assumed to be restored one by one because it is assumed to be a gradual return, but a plurality of devices are simultaneously restored based on the difference between the control target value and the power supply value. You may do it.

  FIG. 6 is a flowchart showing a process of returning the power supply of the device whose contract time has been autonomously performed in the detection unit 53 of the server apparatus 102. The power supply control system 1 does not stop a single device for a long time, but performs a control to stop a plurality of devices in a distributed manner, so that the stop and return processing shown in FIG. The server apparatus 102 is made to perform the process shown in FIG.

The detection unit 53 searches the database 54 at regular time intervals, and detects whether there is a device whose supply state is OFF and a certain time has elapsed from the stop start time. For example, when the contract time is 5 minutes, a device that has passed 5 minutes from the stop start time is detected (step Sb1). If there is no device for which the contract time has elapsed or there is no device whose supply status is stopped, the process of step Sb1 is performed after a certain time has elapsed. On the other hand, when there is a device whose contract time has elapsed, the detection unit 53 reads the address information of the corresponding device from the database 54 in order to restore the device (step Sb2). The detection unit 53 records the supply state of the corresponding device as “ON” and updates the database 54 (step Sb3). Then, the detection unit 53 transmits the read address information and control information including a supply return instruction to the wireless transmitter 103. The wireless transmitter 103 transmits a wireless signal including control information received from the detection unit 53 via the transmission antenna 104 (step Sb4).
In addition, although 5 minutes was mentioned as an example as said contract time, you may make it change with the decreasing rate of an electric power demand.

  4 and 6 of the server apparatus 102 enables control as in the power demand curve shown by the solid line in FIG. 5, and can prevent the supply limit value of the power generation apparatus 101 from being exceeded. It is not necessary to reinforce equipment according to the peak, and it becomes possible to perform power supply according to the current equipment.

FIG. 7 is a flowchart showing a counting process performed by the counting unit 55 of the server apparatus 102. The totaling unit 55 is activated every 24 hours at a certain time, for example, at dawn when the power consumption of the day decreases, and performs the following processing.
First, the totaling unit 55 reads out the number of stops of each device from the database 54 (step Sc1). Next, the totaling unit 55 calculates a discount amount corresponding to the number of stops (step Sc2). Then, the totaling unit 55 outputs the calculated discount amount to the output unit 56 together with information on “No.”, “device name”, and “installation location” of the device (step Sc3). And the total part 55 deletes the frequency | count of a stop of each apparatus of the database 54 (step Sc4).

  By performing the above totaling process, for example, when the output unit 56 is connected to a charge management device of an electric power company, the “No.”, “device name”, and “installation location” By making it possible to specify the contractor number from “,” a fee corresponding to the number of times of suspension is discounted from the monthly power rate.

  In the process of FIG. 4, a flag indicating that the database 54 can be further stopped is provided in the database 54. If the flag is set in advance according to the user's report, the past stop You may make it stop regardless of the frequency | count. In that case, by increasing the number of stops by a predetermined value of 2 or more, the discount amount can be increased in the aggregation.

  The server device described above has a computer system inside.
