With the development of the current society, the demand for electric power energy is continuously increasing, and it is more and more important to stabilize safe power utilization to strengthen the load control of the electric power energy. The existing power load control is to obtain the service condition of the power load in a manual meter reading mode of a power consumer for a long time, and the power consumer can master the power load condition according to the data reflected by an actual energy consumption equipment meter, so that the power consumption distribution of the power consumer can be realized according to the load condition, the reasonable supply of resources is realized, the cost is reduced, the efficiency is improved, and the possibility of power accidents is reduced.
However, such electrical load control by manual meter reading is not only heavy in workload, but also has a high possibility of occurrence of estimated reading, misreading, and missing reading. The low accuracy of the data prevents rapid and accurate control of the electrical load, which may result in loss to the power consumer. In particular, in an industrial enterprise in which a large number of electric devices are present, it is particularly difficult to quickly and accurately control an electric load because of a large number of kinds and numbers of electric devices, different importance of various electric devices due to different process stages, and the like. For example, in the current situation, the way for power consumption management of a power consumption enterprise is to collect engineers of various departments to conduct conference discussion when emergency load regulation is needed, generate a preliminary load control scheme, and evaluate the preliminary load control scheme in combination with the operation efficiency, production plan and the like of various power consumption equipment to form a final load control scheme. And then, on the premise that each department ensures that the scheme is feasible, the power guarantee department appoints an engineer to the site to start and stop certain electric equipment according to the final load control scheme. Obviously, such a solution is inefficient, labor-intensive, requires engineers to be very familiar with the operating conditions of the distribution network and to have a rich field experience, and after the load control is completed, engineers also need to go to the field to see whether the operating conditions of the power supply equipment and the power consumption equipment are normal.
In addition, although some automatic schemes for remote meter reading exist, for power consumers using the schemes, although the accuracy and integrity of data are guaranteed by storing the data in a database, the power load control still needs an experienced engineer to perform autonomous analysis and judgment on the basis of a data field, and the control mode is highly subjective and greatly depends on personal experience of the engineer, so that the effect of load control is very unreliable.

It should be noted that the term "or" is generally employed in its sense including "and/or" unless the context clearly dictates otherwise.
Fig. 1 shows a schematic structural diagram of an electrical load control system 1 according to the invention. As shown in fig. 1, the electrical load control system 1 includes a plurality of electrical load acquisition modules 10 (only one is schematically shown in fig. 1). Each power consumption collecting module 10 may be connected to one power consumption device 60, and is configured to collect a plurality of types of power consumption data of the corresponding power consumption device 60 every predetermined collecting period. For example, the predetermined collection period may be 1 minute, so that the electricity collection module 10 collects electricity data of the electricity consumption device 60 connected thereto every one minute.
The electrical load control system 1 further includes an electrical utilization control module 20, which includes a buffer (not shown in the figure) for buffering the electrical utilization data, also referred to as current electrical utilization data, of the corresponding electrical equipment 60 collected by the plurality of electrical utilization collection modules 10 in the current collection period. For example, the power consumption control module 20 may be configured to write current power consumption data of the power consumption devices 60 collected by the power consumption collection modules 10 into a redis cache based on the modbus protocol.
In addition, each time new power consumption data acquired by the power consumption acquisition module 10 is received, the power consumption control module 20 further transfers the current power consumption data in the buffer to a database (e.g., a hard disk) of the management server 30 connected to the power consumption control module 20. For example, the electricity consumption control module 20 may execute a binning program once per minute, store the data in the buffer in the hard disk mysql database of the management server 30, and request the management server 30 for the data when requested by the management user, for example, through websocket. In this way, at any particular time, the electricity control module 20 stores current electricity data of the current sampling period, and the database of the management server 30 stores electricity data collected by the plurality of electricity collection modules 10 in the collection period before the current collection period, which is also referred to as historical electricity data.
In practical operation, the management user of the power utilization enterprise may monitor the power utilization condition of each power utilization device, for example, the management user may visually check the power utilization condition of each power utilization device through the portable management terminal 40 as shown in the figure or through the management server 30. Here, the power consumption of each power consumption device may be represented by the power consumption data collected by each power consumption collection module as described above, or may be represented by the monitoring signal/digital parameter collected by the monitoring module 50 as described below, or may be represented by a combination of the two. Furthermore, the management user can request the electrical load control system 1 to perform load control as needed. In this case, the management user can issue a load control request to the utility control module 20 by operating the management terminal 40 or directly operating the management server 30, for example. The load control request may specify, for example, a target range (which electric devices) of the load control, such as specifying that a certain production line of a plurality of production lines is subjected to the load control, specifying that electric devices of a certain link of all the production lines are subjected to the load control, or specifying other electric devices that a user wants to control. The load control request may also specify a time range for load control, such as specifying how long in the future to perform load control, etc.
Upon receiving a load control request from a management user, the electricity consumption control module 20 acquires corresponding historical electricity consumption data from the database of the management server 30 according to an instruction in the load control request, and acquires corresponding current electricity consumption data from the buffer of the electricity consumption control module 20. The power consumption control module 20 may acquire current power consumption data and historical power consumption data of some or all of the power consumption devices 60 according to the load control request. Here, it is assumed that the electricity consumption control module 20 acquires the current electricity consumption data and the historical electricity consumption data of all of the plurality of electric devices 60. The power usage control module 20 may combine the acquired historical power usage data and the current power usage data to generate actual power usage data for the plurality of powered devices 60. The electricity consumption control module 20 determines whether the actual electricity consumption data is greater than a safety load threshold preset by a management user.
In some embodiments, if it is determined that the actual power usage data is greater than the safety load threshold preset by the administrative user, the power control module 20 may simulatively set the power usage data of at least one powered device 60 of the plurality of powered devices 60 to zero (i.e., simulate turning off the powered device) to calculate the simulated power usage data of the plurality of powered devices 60. Specifically, the power consumption control module 20 may count the simulated operating currents after unloading some power consumption devices 60 by simulating unloading some power consumption devices 60 from the current operating currents or count the simulated operating currents after loading some power consumption devices 60 by loading some power consumption devices 60 to the current operating currents.
Here, the power consumption control module 20 may sequentially turn off each of the power consumers 60 in a simulation manner according to a rule (e.g., power consumption priority of each power consumer 60) preset by a user until the obtained simulated power consumption data is less than or equal to the safety load threshold. The identifier of the at least one consumer 60 that is switched off in an analog manner can now be known. The power utility control module 20 may form a power utility load control scheme based on the obtained simulated power utility data and the identifier of the at least one power consumer 60.
In one embodiment, the decision of the load control scheme is performed by the management server 30. In this case, the power consumption control module 20 may transmit the power load management scheme to the management server 30, and the management server 30 determines whether to shut down the at least one powered device 60 based on the power load management scheme. If it is determined to shut down the at least one powered device 60, the management server 30 transmits a load control command to the powered control module 20 to shut down the at least one powered device 60. The management server 30 may include hardware devices and software devices such as a server, a workstation, and a switch, and the management server 30 may receive and display the load condition of the electric equipment 60 from the electric control module 20 in real time, and may transmit the load condition to the management terminal 40 in real time for display.
In another embodiment, the decision of the load control scheme is performed by the management terminal 40 connected to the management server 30 by wire or wirelessly. In this case, the electricity control module 20 may transmit the electricity load management scheme to the management server 30, and the management server 30 forwards the electricity load management scheme to the management terminal 40. The management terminal 40 determines whether to shut down the at least one electric device 60 based on the electric load control scheme, and transmits a load control command to the management server 30 if it is determined to shut down the at least one electric device 60. The management server 30 forwards the load control command to the power consumption control module 20 to shut down the at least one powered device 60. Herein, the management terminal 40 may be a portable mobile terminal, and the management user may view the power consumption of each power consumption device 60 whenever and wherever necessary, and may receive a message transmitted by the system whenever and wherever possible, thereby providing higher operational flexibility. Further, although the management terminal 40 is shown as 1 in fig. 1, in other examples, the electrical load control system 1 may include a plurality of management terminals 40, each management terminal 40 being controlled by one management user.
In other embodiments, the power consumption control module 20 may apply different rules to simulate the power consumption data of different power consumption devices 60 of the plurality of power consumption devices 60 to 0 respectively to calculate a plurality of simulated power consumption data smaller than or equal to the safety load threshold, and form a plurality of power consumption load control schemes according to the plurality of simulated power consumption data and the identifiers of the corresponding turned-off power consumption devices 60 respectively.
In this case, in an embodiment, the power usage control module 20 may transmit all of the plurality of power load management schemes to the management server 30, and the management server 30 may select one power load control scheme from the plurality of power load control schemes based on an instruction of a management user and determine whether to shut down the power device 60 corresponding to the selected power load scheme based on the selected power load control scheme. If it is determined to shut down the electric devices 60 corresponding to the selected electric load scheme, the management server 30 transmits a load control command to the electric control module 20 to shut down the electric devices 60 corresponding to the selected electric load scheme.
In another embodiment, the power utilization control module 20 may transmit all of the plurality of power utilization load management schemes to the management server 30, and the management server 30 transmits the plurality of power utilization load management schemes to the management terminal 40. The management terminal 40 selects one electric load control scheme from the plurality of electric load control schemes based on an instruction of the management user, and determines whether to shut down the electric devices 60 corresponding to the selected electric load scheme based on the selected electric load control scheme. If it is determined to shut down the electric devices 60 corresponding to the selected electric load scenario, the management terminal 40 transmits a load control command to the management server 30. The management server 30 forwards the load control command to the electricity usage control module 20 to shut down the electricity usage device 60 corresponding to the selected electricity usage load scheme.
In some embodiments, the electrical load control system 1 may further include a monitoring module 50. Fig. 2 shows a schematic diagram of a monitoring module 50 of the electrical load control system 1 according to an embodiment of the invention. As shown in fig. 2, the monitoring module 50 includes a plurality of monitoring terminals 52 (only one shown in fig. 2 by way of example) and an intelligent gateway 54. Each monitoring terminal 52 is connected to a corresponding one of the plurality of electric devices 60, and is configured to obtain a plurality of monitoring signals of the corresponding electric device. The plurality of monitoring signals includes, for example, voltage, current, relay input, and the like. The monitoring terminal 52 may also convert the plurality of monitoring signals into digital parameters, respectively, including, for example, three-phase voltage, three-phase current, power factor, frequency, power usage, and the like. For example, the monitoring terminal 52 may convert the obtained voltage sampled by the voltage transformer and the current sampled by the current transformer into digital parameters for calculation at the terminal, read out the calculated data through the serial interface, display various parameters according to the preset values, perform communication transmission through the infrared or RS485 interface, complete the monitoring of the operating parameters, and record and store various data.
The intelligent gateway 54 classifies the digital parameters of the plurality of electric devices 60 according to device types and data identification manners, and packages the classified digital parameters according to a predetermined communication protocol to transmit to the connected management server 30. For example, intelligent gateway 54 may classify the digital parameters of each powered device 60 according to the device type of the powered device 60, such as gateway, channel, or power consumer, and the data identification of the obtained device data item.
In some embodiments, monitoring module 50 may also include a fiber optic transceiver 56 that may transmit the digital parameters packaged by intelligent gateway 54 to management server 30 over fiber.
As described above, both the power consumption collection module 10 and the monitoring terminal 52 may be configured to obtain power consumption data of the powered device 60, and the power consumption control module 20 may further determine whether the powered device 60 is safely powered by comparing the obtained data.
In the embodiment according to the present invention, the collection accuracy of the electricity consumption collection module 10 is greater than that of the monitoring terminal 52. For example, the acquisition accuracy of the monitoring terminal 52 is 0.2 level, while the acquisition accuracy of the power consumption acquisition module 10 is 0.2s level, and the lower the number is, the higher the acquisition accuracy is represented by + s. This is because the data collected by the power consumption collecting module 10 is the main data source of the power consumption load control scheme, and therefore the data accuracy requirement is higher.
To further determine the data accuracy, for a specific electric device 60, the electricity control module 20 may determine whether the electricity data collected by the electricity collection module 10 is consistent with the monitoring signal obtained by the monitoring terminal 52, and send an alarm signal to the management server 30 if it is determined that the electricity data collected by the electricity collection module 10 is inconsistent with the monitoring signal obtained by the monitoring terminal 52. Here, depending on the type or parameters of the electricity collection module 10 and the monitoring terminal 52 used, the comparison between the electricity data and the monitoring signal may be performed directly or after conversion into a comparable amount.
To further determine the accuracy of the commands from the administrative user, the powered control module 20 is further configured to, upon receiving a load control command from the administrative user, acknowledge the load control command and transmit the load control command back to the administrative server 30 for the administrative user to acknowledge again. Here, the load control command transmitted back to the management server 30 may highlight, for example, an identifier of the electric device 60 to be turned off by the load control command. The management user may confirm directly at the management server 30 or may receive and confirm the load control command from the management server 30 through the management terminal 40. The power consumption control module 20 may turn off the power consumption device 60 specified in the load control command according to the load control command when receiving the load control command confirmed again by the management user.
In some embodiments according to the present invention, the management server 30 may also perform power integration on the respective electric devices 60. Specifically, since it is known from the formula P — UIcos θ that the powers of the upper voltage class and the lower voltage class are equal (on the premise of neglecting the loss), the power and the current of the low voltage class can be converted into the power and the current of the high voltage class according to the calculation formula, so that different voltage classes (e.g., 35KV, 10KV, 6KV, etc.) can be integrated into the same voltage class. By the method, the information data island effect can be broken through, the data integrity and accuracy are greatly improved, and the problems of low information data integration level, poor interconnectivity and information management dispersion are solved.
