[0068] In order to make the purpose, technical scheme, and advantages of the present application more clearly understood, the present application is further described in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other technical schemes obtained by ordinary technicians in the field belong to the scope of protection of the present application.

[0069] Active power load loading control method and device

[0070] Figure 1 FIG. 2 shows a flow chart of an active power load control method according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0071] In step S110, the resistors in the resistor unit that are currently in a closable state are sorted according to closing priorities in order of power from large to small, so as to obtain a set of resistors corresponding to different closing priorities.

[0072] In this embodiment, the resistance unit is usually composed of several independent dry load boxes, each of which is composed of resistors (such as heating units) with different powers, and different powers are loaded by combining different resistors. The resistance unit is, for example but not limited to: composed of 5 independent dry load boxes, each of which is composed of heating units of four different powers of 50kw / 100kw / 200kw / 400kw. It should be pointed out that this specific embodiment is only exemplary and cannot be used as a limitation on the scope of protection of this application.

[0073] Optionally, before step S110, the following steps may also be included: detecting the power feedback of each resistor in the resistor unit and / or the contact feedback of the contactor electrically connected to each resistor in real time through a sensor; determining the real-time state of each resistor as a closable state or a non-closable state according to the power feedback of each resistor and / or the contact feedback of the contactor electrically connected to each resistor; and updating the state information of each resistor according to the determined real-time state of each resistor. Further, in one implementation of this embodiment, the "closable state" may be an "open state", and the "non-closable state" may be a "closed state", wherein the "open state" and the "closed state" may be determined according to the power feedback of each resistor or the contact feedback of the contactor electrically connected to each resistor. In another implementation of this embodiment, the aforementioned "closable state" refers to the "open and non-fault state", and the "non-closable state" includes the "closed state" and the "fault state", wherein the "open and non-fault state", the "closed state" and the "fault state" may be determined according to the power feedback of each resistor and the contact feedback of the contactor electrically connected to each resistor.

[0074] Then, the process proceeds to step S120 , in which the resistors in the resistor set corresponding to each closing priority are sorted in ascending order according to the number of historical closing times, to obtain a resistor sorting result of the resistor set corresponding to different closing priorities.

[0075] Then, the process proceeds to step S130, where at least one resistor is selected from the resistors currently in the closable state for closing based on the target required active power increment and according to the resistor sorting result of the resistor set corresponding to different closing priorities.

[0076] There are various implementations of step S130. In order to better understand the embodiments of the present application, two exemplary implementations of step S130 are listed below. It should be understood that the present invention is not limited thereto.

[0077] In an exemplary implementation, step S130 can be further implemented as follows: executing steps S130a to S130d at least once until it is determined that the current remaining required active power increment is within the first preset range. In step S130a, based on the current remaining required active power increment, the closing priority to which the next closing resistor belongs is determined; in step S130b, from the resistor set corresponding to the determined closing priority, the resistor with the highest ranking is selected as the next closing resistor for closing; in step S130c, the current remaining required active power increment and the resistor set corresponding to the determined closing priority are updated respectively; in step S130d, it is determined whether the current remaining required active power increment is within the first preset range?

[0078] In another exemplary implementation, step S130 can be further implemented as follows: executing steps S130a′ to S130d′ at least once until it is determined that the current remaining required active power increment is within the first preset range. In step S130a′, the highest closing priority of the closing resistor to be selected is determined based on the current remaining required active power increment; in step S130b′, at least one closing resistor with the highest ranking is selected from the resistor set of the determined closing priority for opening, and the number of the at least one closing resistor is determined according to the "current remaining required active power increment" and the "power corresponding to the determined closing priority"; in step S130c′, the current remaining required active power increment is updated; in step S130d′, it is determined whether the current remaining required active power increment is within the first preset range?

[0079] It should be pointed out that in the two exemplary implementations of step S130 in the previous paragraph, the initial value of the current remaining required active power increment is the target required active power increment; the first preset range is, for example but not limited to [0, m], m can be set as needed, and m is, for example but not limited to, equal to the load corresponding to the minimum power (e.g., 50w) in the resistance unit. In addition, in step S130b' of the previous paragraph, "the number of at least one closing resistor" can be, for example, equal to the integer quotient of "the current remaining required active power increment" divided by "the power corresponding to the determined closing priority"; in step S130c', the current remaining required active power increment is equal to the remainder of "the target required active power increment" divided by "the power corresponding to the determined closing priority".

[0080] In an embodiment, for example, the target required active power increment can be obtained by automatic determination. For example, before step S130, the target required active power increment can be obtained by automatically determining the following steps: obtaining the power sum of each resistor currently in the closed state in the resistor unit; determining the target required active power increment according to the difference between the predetermined power and the power sum. In practical applications, for example, the target required active power increment can be determined in real time before step S110; for example, the target required active power increment can also be determined before step S110 in response to detecting a resistor fault currently in the closed state or in response to a change in the predetermined power; and after determining the target required active power increment, it is determined whether the determined target required active power increment is greater than a preset value (for example, m), and if so, then proceeding to step S110. Among them, the predetermined power can be set according to the process requirements, and different predetermined powers can be set correspondingly for different process sections.

[0081] Specifically, the aforementioned “obtaining the power sum of each resistor in the resistor unit that is currently in the closed state” can, for example, detect the target electrical parameters (such as current value, voltage value) of each resistor in the resistor unit that is currently in the closed state through a sensor; and calculate the power sum of each resistor that is currently in the closed state according to the target electrical parameters of each resistor. In addition, the aforementioned “detecting whether there is a resistor fault in the current closed state” can be specifically implemented according to the power feedback of each resistor and / or the contact feedback of the contactor electrically connected to each resistor.

[0082] In addition, the resistance unit of this embodiment also includes two closing connection modes: a star closing connection mode and a triangle closing connection mode. Based on this, the method of this embodiment may also include: after the system is started, the input voltage currently given to the resistance unit; if the input voltage is the first voltage, the selected resistance is closed in step S130 using the triangle closing connection mode; if the current input voltage is the second voltage, the selected resistance is closed in step S130 using the star closing connection mode; wherein the first voltage is less than the second voltage, for example but not limited to: the first voltage is 6.5kV, and the second voltage is 10kV.

[0083] In order to implement the active power load loading control method of the above embodiment, another embodiment of the present invention further provides a structure diagram of an active power load loading control device, as shown in FIG. Figure 2As shown, the device 200 includes a first sorting module 210 and a closing control module 220. It should be noted that, since the following embodiments are for implementing the aforementioned active power load loading control method embodiment, each module in the device 200 is provided for implementing each step of the aforementioned active power load loading control method, and therefore the present invention is not limited to the following embodiments, and any device or module that can implement the aforementioned active power load loading control method should be included in the protection scope of the present invention.

[0084] Specifically, the first sorting module 210 is used to sort the resistors in the resistor unit that are currently in a state that can be closed according to the order of power from large to small, and obtain a resistor set corresponding to different closing priorities; and sort the resistors in the resistor set corresponding to each closing priority according to the order of the number of historical closing times from small to large, and obtain the resistor sorting results of the resistor set corresponding to different closing priorities. The closing control module 220 is used to select at least one resistor from the resistors that are currently in a state that can be closed for closing based on the target required active power increment and the resistor sorting results of the resistor set corresponding to different closing priorities.

[0085] Optionally, the closing control module 220 is also used to execute the operation of "determining the closing priority to which the next closing resistor belongs based on the current remaining required active power increment; selecting the resistor with the highest ranking from the resistor set corresponding to the determined closing priority as the next closing resistor for closing; updating the current remaining required active power increment and the resistor set corresponding to the determined closing priority respectively; and determining whether the current remaining required active power increment is within a first preset range?" at least once until it is determined that the current remaining required active power increment is within the first preset range.

[0086] Optionally, the device 200 also includes a target required active power increment determination module, which is used to: obtain (for example, periodically, in real time, or when an event occurs) the power sum of each resistor in the resistance unit that is currently in a closed state; and determine the target required active power increment based on the difference between a predetermined power and the power sum.

[0087] Optionally, the device 200 also includes a resistor state update module, which is used to: detect the power feedback of each resistor in the resistor unit and / or the contact feedback of the contactor electrically connected to each resistor in real time through a sensor; determine the real-time state of each resistor as a closing state or a non-closing state based on the power feedback of each resistor and / or the contact feedback of the contactor electrically connected to each resistor; and update the state information of each resistor based on the determined real-time state of each resistor.

[0088] It should be noted that the device 200 of this embodiment is a device corresponding to the active power load loading control method of the aforementioned embodiment. Therefore, all technical details of the active power load loading control method of the aforementioned embodiment are applicable to the device 200 of this embodiment. For the sake of simplicity, some content that is repeated with the active power load loading control method of the aforementioned embodiment is omitted in this embodiment.

[0089] Active power load shedding control method and device

[0090] Figure 3 FIG. 2 shows a flow chart of an active power load shedding control method according to an embodiment of the present invention. Figure 3 As shown, the method includes:

[0091] In step S310, the resistors currently in the disconnectable state in the resistor unit are sorted according to disconnection priorities in order of power from large to small, so as to obtain a set of resistors corresponding to different disconnection priorities.

[0092] In this embodiment, the resistance unit is composed of several independent dry load boxes, each of which is composed of heating units with different powers, and load shedding with different powers is achieved by combining different heating units. The resistance unit is, for example but not limited to: composed of 5 independent dry load boxes, each of which is composed of heating units with four different powers of 50kw / 100kw / 200kw / 400kw; it should be pointed out that this example is only exemplary and cannot be used as a limitation on the scope of protection of this application.

[0093] Optionally, before step S310, the following steps may also be included: detecting the power feedback of each resistor in the resistor unit and / or the contact feedback of the contactor electrically connected to each resistor in real time through a sensor; determining the real-time state of each resistor as a separable state or an inseparable state according to the power feedback of each resistor and / or the contact feedback of the contactor electrically connected to each resistor; and updating the state information of each resistor according to the determined real-time state of each resistor. Furthermore, in an implementation of the present embodiment, the "separable state" may be a "closed state", and the "inseparable state" may be an "opened state", wherein the "closed state" and the "opened state" may be determined according to the power feedback of each resistor or the contact feedback of the contactor electrically connected to each resistor. In another implementation of this embodiment, the aforementioned "separable state" refers to "closed and non-fault state", and the "non-separable state" includes "open state" and "fault state", among which "open and non-fault state", "closed state" and "fault state" can be determined based on the power feedback of each resistor and the contact feedback of the contactor electrically connected to each resistor.

[0094] Then, the process proceeds to step S320, in which the resistors in the resistor set corresponding to each opening priority are sorted in descending order according to the number of historical closing times, to obtain a resistor sorting result in the resistor set corresponding to different opening priorities.

[0095] Then, the process proceeds to step S330, and based on the target required active power reduction and according to the resistor sorting result in the resistor set corresponding to different disconnection priorities, at least one resistor is selected from the resistors currently in the disconnectable state for disconnection.

[0096] There are various implementations of step S330. In order to improve the understanding of the embodiments of the present application, two exemplary implementations are listed below, but it is understood that the present application is not limited thereto.

[0097] In an exemplary implementation, step S330 can be further implemented as: executing steps S330a to S330d at least once until it is determined that the current remaining required active power reduction is within the second preset range. Wherein, in step S330a, based on the current remaining required active power reduction, determine the disconnection priority to which the next disconnection resistor belongs. In step S330b, select the resistor with the highest ranking from the resistor set corresponding to the determined disconnection priority as the next disconnection resistor for disconnection. In step S330c, update the current remaining required active power reduction and the resistor set corresponding to the determined disconnection priority, respectively. Step S330d, determine whether the current remaining required active power reduction is within the second preset range?

[0098] In another exemplary implementation, step S330 can be further implemented as follows: executing step S330a′ to step S330d′ at least once until it is determined that the current remaining required active power reduction is within the second preset range. In step S330a′, the highest disconnection priority of the disconnection resistor to be currently selected is determined based on the current remaining required active power reduction; in step S330b′, at least one disconnection resistor with the highest ranking is selected from the resistor set of the disconnection priority determined in step S330a′, and the number of the at least one disconnection resistor is determined according to the "target required active power reduction" and the "power corresponding to the determined disconnection priority"; in step S330c′, the current remaining required active power reduction is updated; in step S330d′, it is determined whether the current remaining required active power reduction is within the second preset range?

[0099] In step S330b' of the previous paragraph, "the number of at least one disconnecting resistor" can be equal to the integer quotient of "the target required active power reduction" divided by "the power corresponding to the determined disconnecting priority"; in step S330c', the current remaining required active power reduction is equal to the remainder of "the current remaining required active power reduction" divided by "the power corresponding to the determined disconnecting priority". In addition, the initial value of the current remaining required active power reduction is the target required active power reduction.

[0100] It should be noted that in the above two exemplary implementations of step S330, the second preset range is, for example but not limited to, [0, m], where m can be set as needed, and m is, for example but not limited to, equal to the load corresponding to the minimum power (e.g., 50 kW) in the resistance unit.

[0101] Optionally, before step S330, the following steps may be further included: obtaining the power sum of each resistor in the resistor unit that is currently in the closed state; determining the target required active power reduction, which is equal to the difference between the power sum and the predetermined power. In practical applications, for example, the target required active power reduction may be determined in real time before step S310; or the target required active power reduction may be determined before step S310 in response to detecting a resistor fault that is currently in the closed state; and after determining the target required active power reduction, it is determined whether the determined target required active power reduction is greater than a preset value (e.g., m), and if so, then proceeding to step S310.

[0102] Specifically, the aforementioned “obtaining the power sum of each resistor in the resistor unit that is currently in the closed state” can, for example, detect the target electrical parameters of each resistor in the resistor unit that is currently in the detachable state through a sensor; based on the target electrical parameters of each resistor, calculate the power sum of each resistor that is currently in the closed state. The target electrical parameter can be current, voltage, etc. In addition, the aforementioned “detecting whether there is a resistor fault in the current closed state” can be specifically achieved based on the changes in the power feedback of each resistor and the changes in the contact feedback of the contactor electrically connected to each resistor.

[0103] In order to implement the active power load shedding control method of the above embodiment, another embodiment of the present invention further provides a structure diagram of an active power load shedding control device, as shown in FIG. Figure 4 As shown, the device 400 includes a second sorting module 410 and a switch-off control module 420. It should be noted that since the following embodiments are for implementing the aforementioned method embodiments, each module in the device 400 is provided for implementing each step of the aforementioned method, and therefore the present invention is not limited to the following embodiments, and any device or module that can implement the aforementioned method should be included in the protection scope of the present invention.

[0104] Specifically, the second sorting module 410 is used to sort the resistors in the resistor unit that are currently in a detachable state according to the order of power from large to small, and obtain a resistor set corresponding to different detaching priorities; and sort the resistors in the resistor set corresponding to each detaching priority according to the order of the number of historical closing times from large to small, and obtain the resistor sorting results in the resistor set corresponding to different detaching priorities. The detaching control module 420 is used to select at least one resistor from the resistors that are currently in a detachable state for detaching based on the target required active power reduction and the resistor sorting results in the resistor set corresponding to different detaching priorities.

[0110] Reactive power load loading control method and device

[0111] Figure 5 FIG. 2 shows a flow chart of a reactive power load control method according to an embodiment of the present invention. Figure 5 As shown, the method includes:

[0112] In step S510, the reactors in the set of reactors currently in the loadable state in the reactor unit are sorted in ascending order according to the number of historical closing times, to obtain a first sorting result.

[0113] In this embodiment, the reactor unit is usually composed of a plurality of reactors, and the required reactive power is achieved by stepless loading and unloading of each reactor unit. The plurality of reactors can be set as required, preferably with the same specifications, such as but not limited to 8 2000Kvar reactors; but can also be set with different specifications.

[0114] Then, the process proceeds to step S520 , where at least one reactor is selected from the reactor set based on the target required reactive power increment and loaded in sequence in a stepless regulation manner according to the first sorting result.

[0115] It can be understood that in step S520, in the process of selecting at least one reactor from the reactor set according to the first sorting result and loading them in sequence in a stepless adjustment manner, if the reactor selected from the reactor set is in a closed state, the output impedance of the reactor is directly adjusted in a stepless adjustment manner for loading; if the reactor selected from the reactor set is in an open state, it is first closed, and after closing, the output impedance of the reactor is adjusted in a stepless adjustment manner for loading.

[0116] In this embodiment, for example, the required reactive power increment for the target can be automatically determined. For example, after step S510, the required reactive power increment for the target can be automatically determined by the following steps: obtaining the reactive power detection value of the reactor currently in the closed state in the reactor unit in real time or periodically; comparing the detection value with the set value; if the first difference between the set value and the detection value is greater than the first preset value, then entering step S510. Furthermore, before step S520, the following steps are also included: if the first difference between the set value and the detection value is greater than the first preset value, the required reactive power increment for the target is determined based on the detection value of the reactive power and the preset value. It can be understood that the preset value of reactive power can be set according to the process requirements, and different process sections can correspond to different preset values.

Further, in an exemplary implementation of this embodiment, the "loadable state" includes "closed and not fully loaded state" and "opened state", and the "unloadable state" is "closed and fully loaded state". In another exemplary implementation of this embodiment, the "loadable state" includes "closed, not fully loaded and non-fault state" and "opened and non-fault state", and the "unloadable state" includes "closed and fully loaded state" and "fault state".

[0118] Optionally, in this embodiment, when the selected inductor is loaded in a stepless adjustment manner, it also includes: loading the portion of the power segment of the inductor that is less than a preset power according to a first frequency; loading the portion of the power segment of the inductor that is not less than the preset power according to a second frequency, the first frequency being lower than the second frequency.

[0120] Specifically, the third sorting module 610 is used to sort the reactors in the reactor set currently in the loadable state in the reactor unit in order from small to large according to the number of historical closing times, and obtain a first sorting result. The loading control module 620 is used to select at least one reactor from the reactor set based on the target required reactive power increment and the first sorting result to load in sequence in a stepless adjustment manner.

[0121] Optionally, the device 600 further includes a comparison and judgment module, which is used to obtain the reactive power detection value of the reactor currently in the closed state in the reactor unit in real time or periodically; compare the detection value with the set value; if the first difference between the set value and the detection value is greater than the first preset value, perform the operations in the third sorting module 610 and the loading control module 620. Further, optionally, the device 600 further includes a target required reactive power increment determination module, which is used to: if the first difference between the set value and the detection value is greater than the first preset value, determine the target required reactive power increment according to the detection value of reactive power and the preset value.

[0122] Optionally, the device 600 also includes a frequency adjustment module, which is used to load the part of the power range of the reactor that is less than a preset power according to a first frequency when the selected reactor is loaded in a stepless adjustment manner; and to load the part of the power range of the reactor that is not less than the preset power according to a second frequency, wherein the first frequency is lower than the second frequency.

Therefore, all technical details of the reactive power load loading control method of the aforementioned embodiment are applicable to the device 600 of this embodiment.
