Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-2 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application provides a supermarket power consumption management method, which can be applied to a supermarket power supply system, wherein the supermarket power supply system can be a system for managing power consumption conditions in a supermarket, specifically can be composed of a central control console, a power distribution network and power consumption equipment, and can be shown in fig. 1, wherein the central control console can be deployed in a supermarket background and used for monitoring and scheduling the power consumption conditions of all the power consumption equipment in the supermarket, the power distribution network can be arranged between power supply input of the supermarket and the power consumption equipment, and the power consumption equipment can obtain electric energy from the power supply input of the supermarket through the power distribution network. Further, the central console may be configured to control a power supply switch in the power distribution network, so as to implement processing of supplying power to the electric device or stopping power supply according to actual requirements.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
In implementation, after the electric equipment is connected to a power distribution network and enters a working state, the central console can record the power consumption conditions of various electric equipment in real time in a form of generating a power fluctuation curve, namely record historical power consumption data of various electric equipment. Based on this, when the central console manages the power on/off of the electric equipment, the central console can periodically read the historical power consumption data of various types of electric equipment in the current period, which are recorded locally, and then determine the power fluctuation range of the various types of electric equipment according to the historical power consumption data.
Optionally, the power condition of one type of powered device may be mapped by the power condition of a single powered device, and accordingly, the processing of step 201 may be as follows: acquiring historical power consumption data of each piece of electric equipment under a target category, and determining the power fluctuation range of each piece of electric equipment; and taking the power fluctuation range with the overlapping rate not less than the preset ratio in the power fluctuation range of each electric device as the power fluctuation range of the electric devices under the target category.
The target type of electric equipment may be any type of electric equipment deployed in a supermarket.
In implementation, when determining the power fluctuation ranges of various types of electric equipment, the central console may classify the electric equipment according to the types. For the target category, the central console may periodically obtain historical power consumption data of each electric device in the target category, and then determine the power fluctuation range of each electric device. Then, the central console can synthesize the power fluctuation range of each electric device under the target category, and select the power fluctuation range with the overlapping rate larger than the preset ratio as the power fluctuation range of the electric device under the target category. For example, the target category includes 5 electric devices, the power fluctuation ranges are "50 to 70", "55 to 75", "52 to 68", "50 to 65", and "53 to 71", respectively, and the preset ratio is 60%, and the power fluctuation range with the overlap ratio of not less than 60% may be "52 to 70".
In implementation, the central console may be preset with a system power upper limit value of the supermarket, and at any time, the total power of all the electric devices in the supermarket should not exceed the system power upper limit value. Therefore, after the power fluctuation ranges of various electric devices are determined, the central control console can plan the operation time intervals of the various electric devices in the supermarket according to the preset system power upper limit value and the power fluctuation ranges, and generate the operation time interval table of the electric devices. The operation period table can record the operation period and the shutdown period of various electric equipment. Further, the central console may supply power to the electrical devices in the operation period at different times based on the operation period table.
Optionally, when the operation duration table is set, the operation duration table may be sequentially set for the electric devices, and correspondingly, the partial processing in step 202 may be as follows: dividing all electric equipment into normally-open electric equipment, short-switch electric equipment and short-switch electric equipment; determining the allocable power according to the power fluctuation range of the normally-open electric equipment and a preset system power upper limit value; setting an operation time period of the short-off type electric equipment based on the allocable power amount and the power fluctuation range of the short-off type electric equipment; the operation period of the short-switch-type electric device is set based on the operation period of the short-switch-type electric device and the power fluctuation range of the short-switch-type electric device.
In implementation, the central console can divide the electric equipment in the supermarket into normally-open electric equipment, short-off electric equipment and short-open electric equipment according to different operation time period requirements of the electric equipment. The normally-on electric equipment can be electric equipment which needs to be continuously turned on in a long time period, such as lighting equipment, refrigeration equipment and the like, the short-off electric equipment can be electric equipment which has working duration far longer than shutdown duration in a certain time period, such as air conditioners, fresh-keeping equipment and the like, the short-on electric equipment can be electric equipment which is in a running state only in part of time, and is in a shutdown state in other time, such as food processing equipment. Then, the central console may record the operation time period of the normally-open electric device in the operation time period table, and determine the difference between the upper limit value of the power fluctuation range of the normally-open electric device and the preset upper limit value of the system power as the allocable power amount. Next, the center console may set the operation period of the short-off type electric device based on the allocable power amount and the power fluctuation range of the short-off type electric device. Finally, the central console can set the operation time period of the short-switch-on electric equipment based on the operation time period of the short-switch-off electric equipment and the power fluctuation range of the short-switch-on electric equipment, so that the operation time period setting of all the electric equipment is completed.
And 203, when the real-time total power is detected to be larger than the upper limit value of the system power, determining a plurality of electric equipment in the running state at the current moment according to the running period table.
In implementation, the central console may monitor the real-time total power generated by all the electric devices in the supermarket, and the real-time total power may be obtained by detecting trunk parameters of the power distribution network. When the real-time total power is detected to be larger than the preset upper limit value of the system power, the central control console can judge that the power distribution network is in an overload state at the current moment and needs to shut down part of the electric equipment. Therefore, the central console may read the runtime segment table generated in step 202, and determine the plurality of electrical devices in the running state at the current time according to the runtime segment table.
Optionally, only the electric device with power greater than the specified value may be controlled, and the corresponding processing may be performed, and the determination processing of the electric device in step 203 may be as follows: and determining a plurality of electric devices which are in the running state at the current moment and have the power fluctuation range above a preset adjustable threshold value according to the running period table.
In implementation, when the central console detects that the real-time total power of the supermarket power utilization system is greater than the preset system power upper limit value, the generated running time period table can be read, and all the power utilization equipment in the running state at the current moment can be screened from the running time period table. Then, the central console may further screen out a plurality of electric devices whose power fluctuation ranges are all above a preset adjustable threshold value from all the electric devices in the operating state according to the power fluctuation ranges of the various electric devices acquired in step 201, that is, a plurality of electric devices whose lower limit values of the power fluctuation ranges are greater than the preset adjustable threshold value.
And step 204, taking the difference between the real-time total power and the upper limit value of the system power as a standard, and suspending power supply for the target electric equipment in the plurality of electric equipment.
In implementation, when the power distribution network is in an overload state, the central console may first calculate a difference between the total real-time power and an upper limit value of the system power, and then select one or more target electrical devices from the plurality of electrical devices determined in step 203 based on the difference, so that the total real-time power of all the target electrical devices is just greater than or equal to the difference. Here, the total value just greater than the difference value can be understood as: when any target electric equipment is removed, the total value of the real-time total power is smaller than the difference value. Further, the central console may suspend power to all target powered devices.
Optionally, different power utilization devices may have different power utilization priorities, and accordingly, the processing of step 204 may be as follows: and taking the difference between the real-time total power and the upper limit value of the system power as a standard, and suspending power supply for target electric equipment in the plurality of electric equipment according to the operation priority corresponding to various electric equipment.
In implementation, different types of electric equipment in the supermarket power supply system can correspond to different operation priorities, at the same time, the supermarket power supply system preferentially supplies power to the electric equipment with high operation priority, and when the residual power load capacity is met, the supermarket power supply system supplies power to the electric equipment with low operation priority. Therefore, when the real-time total power is greater than the upper limit value of the system power, the central console can preferentially suspend power supply to the target electric equipment with low operation priority by taking the difference between the real-time total power and the upper limit value of the system power as a standard and referring to the operation priority corresponding to various electric equipment.
And step 205, when the real-time total power is detected to be smaller than the preset system power recovery value, supplying power to the electric equipment according to the operation period table.
In an implementation, after the central console suspends the process of supplying power to the target electric device in step 204, the central console may continue to monitor the real-time total power of the supermarket power supply system. When the detected real-time total power is smaller than the preset system power recovery value, the central console may determine the electric devices currently in the operation period according to the operation period table, and supply power to the electric devices. It should be noted that the system power recovery value may be continuously adjusted by the central console according to the change of the detection time, and at least a difference between the system power recovery value and the system power upper limit value needs to be satisfied, which is greater than the expected power sum of the to-be-started electrical equipment. The expected power here may be determined by the central console from the power fluctuation ranges of the various types of consumers in step 201.
Optionally, different power utilization devices may have different power utilization priorities, and accordingly, the processing of step 205 may be as follows: and when the real-time total power is detected to be smaller than a preset system power recovery value, sequentially supplying power to the electric equipment according to the operation period table and the operation priority corresponding to various electric equipment.
In implementation, when it is detected that the total real-time power of the supermarket power supply system is smaller than a preset system power recovery value, the central control console may determine, according to the operation period table, that the current time is in the operation period, but no power-supplied electric device is obtained. Then, the central console may rank the electric devices according to the operation priorities corresponding to the electric devices, where the operation priority of the electric device that is ranked more forward is higher. Further, the central console may sequentially supply power to the electrical devices based on the ranking results.
Optionally, the total power range corresponding to each operating period may be recorded in the operating period table, and whether an abnormal electrical device exists may be determined by determining whether the real-time total power is within the total power range, where the following processing may correspondingly exist: when the detected real-time total power is larger than the total power range corresponding to the operation period to which the current time belongs, determining a plurality of electric devices in the operation state at the current time; and determining abnormal electric equipment with real-time power larger than the corresponding power fluctuation range in the plurality of electric equipment, and suspending power supply for the abnormal electric equipment.
In an implementation, when setting the operation period table of the electrical device, the central console may generate a corresponding total power range for each time, and record the total power range in the operation period table. The total power range can be calculated from the power fluctuation ranges of the various types of electric devices generated in step 201. Then, when monitoring the real-time total power of the electric equipment in the supermarket power supply system, the central control console can compare the real-time total power with the total power range. If the detected real-time total power is larger than the total power range corresponding to the operation time period to which the current time belongs, the central control console can further determine a plurality of electric devices in the operation state at the current time, and determine abnormal electric devices of which the real-time power is larger than the corresponding power fluctuation range from the plurality of electric devices, so that the power supply for the abnormal electric devices can be suspended.
By adopting the supermarket power management method disclosed by the application, the central control console of the supermarket power supply system obtains the power fluctuation range of various electric equipment, sets the operation period table of the electric equipment, and then can manage the power on and off of the electric equipment according to the operation period table and the real-time total power. Therefore, the power consumption of various electric equipment is macroscopically planned based on the operation period table, and the on-off of the electric equipment is adjusted in detail by combining the real-time total power, so that the electric energy consumption of the electric equipment in the supermarket can be reasonably and effectively managed.
