Abstract
Description
Technical Field
[0001] This invention relates to the field of power electronics technology, and in particular to a control method, control system, energy-consuming device, and medium for an energy-consuming device. Background Technology
[0002] With the continuous development of the Global Energy Internet, the trend of grid connection for renewable energy power generation such as wind and solar power is becoming increasingly strong. However, the power generation of these renewable energy sources is intermittent and uncertain, and traditional AC power grids cannot absorb them normally. Considering that large-scale power resources are mostly distributed in remote areas far from the load, the current main method is to use DC transmission technology to connect new energy systems, which are supported by renewable energy, to the AC power grid. The electricity generated by the new energy system is collected at the converter station, where it is converted into DC power. Then, it is transmitted via DC transmission system to achieve long-distance, large-capacity power transmission, and finally, it is connected to the AC power grid.
[0003] In practical applications, because the response speed of DC transmission systems is much faster than that of renewable energy systems, if a fault occurs in the DC transmission system, it will quickly disconnect in response to the fault. However, the response speed of renewable energy systems is slower, and they continue to generate electricity, leading to overvoltage phenomena within the converter station. This seriously jeopardizes the stable operation of the converter station. The deployment of energy-consuming devices can effectively avoid this situation. Therefore, how to accurately control and implement the deployment of energy-consuming devices has become one of the important development directions for adapting renewable energy systems to grid connection.

[0046] The core of this invention is to provide a control method, control system, energy-consuming device, and medium for an energy-consuming device. After each activation, the energy-consuming device is cooled based on a cooling time and remains self-locked within the corresponding cooling time, thereby avoiding the impact of continuous high temperature on the lifespan of the energy-consuming device and extending its service life. Each time it self-locks, a suitable cooling time is determined according to a preset correspondence to restore the activation capability of the energy-consuming device as quickly as possible, effectively achieving accurate control over the activation of the energy-consuming device.
[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0048] See Figure 1 As shown, Figure 1 This is a flowchart illustrating a control method for an energy-consuming device provided by the present invention; to solve the above-mentioned technical problems, the present invention provides a control method for an energy-consuming device, comprising:
[0049] S11: When an energy-consuming device is put into operation, determine the total heat generated during this operation.
[0050] S12: Determine the cooling time corresponding to the total heat based on the total heat and the preset correspondence; the preset correspondence includes the correspondence between heat and cooling time.
[0051] S13: When the energy-consuming device is put into operation for the current time, control the energy-consuming device to switch from the first state to the second state, and maintain the second state according to the cooling time; the first state is configured to indicate that the energy-consuming device is allowed to be put into operation, and the second state is configured to indicate that the energy-consuming device is not allowed to be put into operation.
[0052] It is easy to understand that energy-consuming devices inevitably generate heat during the energy consumption process, which leads to the degradation of material properties. Their operation is inevitably accompanied by irreversible physical, chemical, or material damage. Therefore, energy-consuming devices have a limited lifespan. To avoid high costs and frequent replacements due to short lifespans, energy-consuming devices need to cool down for a period of time after each use. During this period, the energy-consuming device remains self-locked, locked in a second state, and will not be used again. Based on this, the present invention provides a control method for energy-consuming devices to configure the cooling time, i.e., the self-locking time, of the energy-consuming device.
[0053] Understandably, to ensure adequate cooling of energy-consuming devices, for any given activation process, the control system of the energy-consuming device determines the total heat generated during that activation. Based on this total heat, a corresponding cooling time is determined. Cooling time is positively correlated with total heat; the higher the total heat, the longer the cooling time. When the heat generated by the energy-consuming device is high, extending the cooling time appropriately slows down damage accumulation, thereby extending its service life. After the activation is complete, the device is controlled to maintain a second state of cooling for the predetermined time, achieving self-locking. Once cooling is complete, i.e., after the second state has maintained the cooling time, the self-locking is released, allowing the device to be activated again for subsequent use. "Energy-consuming device activation complete" means that after being activated, the energy-consuming operation is finished, and the device is about to be disconnected, transitioning from an activated to an unused activated operating mode.
[0054] It should be noted that the energy-consuming device has two operating modes: in use and not in use. When not in use, it also has two operating states (state one and state two). If the energy-consuming device is in state one, it indicates that the device has completed cooling or does not require cooling, and the control system allows it to be used, flexibly controlling its activation based on demand. If the energy-consuming device is in state two, it indicates that the device is still cooling, and the control system does not allow it to be used; the control system will not control its activation. "In use" refers to putting the energy-consuming device into operation for energy consumption. Specifically, this involves connecting the energy-consuming device to the output terminal of the target power supply module, utilizing its energy-consuming function to consume the electrical energy output by the target power supply module. This application does not specifically limit the specific type or implementation method of the energy-consuming device.
[0055] It is not difficult to understand that this application does not impose any special limitations on the specific method for determining the total heat. It can be achieved through various methods such as detecting temperature, current, and heat flux density. The total heat refers to all the heat generated by the energy-consuming device during the entire commissioning process. It can be updated and determined in real time during the commissioning process of the energy-consuming device. Specifically, it can be calculated in real time during the entire commissioning process of the energy-consuming device or calculated multiple times according to a specific period to determine the total heat corresponding to the entire commissioning process. This application does not impose any special limitations on the specific implementation method of the preset correspondence. The cooling time required for different heats can be predetermined based on experience or simulation. The preset correspondence can be implemented using mapping tables or other methods. By pre-constructing the preset correspondence, the energy-consuming device can directly find the reasonable and effective cooling time corresponding to the safe temperature range according to the preset correspondence, ensuring the effect of cooling on extending the life of the energy-consuming device. This application does not impose any special limitations on the specific implementation method of the first state and the second state. It can be achieved by configuring corresponding state bits for the energy-consuming device in the control system. It is only necessary to be able to cooperate with the control system to confirm whether the energy-consuming device can be commissioned normally based on the process of this state switching.
[0056] Specifically, cooling suppresses or slows down the rate of lifespan-limiting mechanisms by controlling temperature, essentially reducing the rate of damage accumulation. This effectively inhibits thermal aging or fatigue, suppresses chemical degradation such as oxidation, and stabilizes the electrical performance of energy-consuming devices, thereby effectively extending their service life. The energy-consuming device control method provided in this application can be applied in the field of flexible DC transmission technology. It is installed in flexible converter stations corresponding to new energy systems, and used in high-voltage flexible DC converter stations to configure and control the self-locking time of energy-consuming devices in flexible DC transmission systems. When a fault occurs and the DC transmission system is disconnected, the energy-consuming device is activated and connected to the output terminal of the new energy system to consume the electrical energy generated by the new energy system, thereby preventing overvoltage phenomena in the converter station and ensuring the stable operation of the converter station. The energy-consuming device can also be applied in other scenarios, consuming the electrical energy output by the target power supply module by activating the energy-consuming device. This application does not specifically limit the specific application scenarios of the energy-consuming device.
[0057] In practical applications, a power system may simultaneously install multiple energy-consuming devices to achieve redundancy and ensure effective energy consumption of the target power supply module in the power system. At this time, a target power supply module will be connected to multiple energy-consuming devices to consume energy. Moreover, for an energy-consuming device, it also needs to be put into operation multiple times during the operation of the power system. Therefore, the control method for energy-consuming devices provided in this application can be independently applied to any energy-consuming device in any putting process. By calculating the total heat generated by each energy-consuming device in a single putting process, and then setting different cooling times according to the specific amount of total heat generated, the method controls each energy-consuming device to be cooled reasonably and effectively according to the set cooling time after each putting process, thereby quickly restoring the putting capacity of the energy-consuming device. This application does not specifically limit the implementation method of the energy-consuming device. Generally speaking, a fixed start-up time is preset for the energy-consuming device. After the control system controls the energy-consuming device to start up for the corresponding start-up time, the energy-consuming device will automatically cut off the start-up. Alternatively, after the control system issues the start-up control command, it will start the start-up time. After the start-up time is completed, it will issue a cut-off control command to control the energy-consuming device to end the start-up, thus completing one start-up. Then, the cooling time is configured according to the total heat determined during the start-up process, and the cooling is controlled to achieve the cooling.
[0058] This application provides a control method for energy-consuming devices. By determining the total heat generated by each energy-consuming device during its operation, the method determines and sets the corresponding cooling time for each energy-consuming device based on the total heat. Different cooling times are set according to different total heat conditions, so that each energy-consuming device can determine the most suitable cooling time based on the actual situation after each operation. This achieves optimized configuration of cooling time after the energy-consuming device starts working, quickly restores the operation capacity of the energy-consuming device, and effectively extends the service life of the energy-consuming device in conjunction with cooling operations.
[0059] As an optional embodiment, the preset correspondence includes several preset heat ranges and several preset times that correspond one-to-one with the several preset heat ranges;
[0060] The cooling time corresponding to the total heat is determined based on the total heat and a preset correspondence, including:
[0061] Compare the total calorie count with several preset calorie count intervals to determine the preset calorie count interval in which the total calorie count falls.
[0062] Determine the preset time corresponding to the preset heat range in which the total heat is located;
[0063] The preset time corresponding to the preset heat range where the total heat is located is determined as the cooling time corresponding to the total heat.
[0064] It is understandable that the preset correspondence can be implemented using a one-to-one preset heat range and preset time. Before the energy-consuming device starts working, the total heat coverage range is determined in advance based on the approximate heat generation of the energy-consuming device in the actual application scenario. This coverage range is then divided into several preset heat ranges based on the heat magnitude. Each preset heat range is a quantified heat range, and a corresponding preset time is set for each preset heat range. After the energy-consuming device is put into use, the preset heat range containing the total heat and its corresponding preset time are determined based on the established correspondence between the total heat of the energy-consuming device and the several preset heat ranges. Different cooling times are then set for each energy-consuming device based on the range containing the total heat. This application does not impose any specific limitations on the number of preset heat ranges and preset times, or their implementation methods. The interval step size of each preset heat range can be flexibly adjusted according to the actual application. Taking a preset correspondence including three preset heat ranges as an example, the preset correspondence can be:
[0065] ;
[0066] in, The final determined cooldown time, Preset heat range The corresponding preset time, Preset heat range The corresponding preset time, Preset heat range The corresponding preset times, W1, W2, and W3 are three preset heat values, in J (joules). These three preset heat values establish three preset heat ranges. , , .
[0067] Specifically, a preset correspondence can be achieved by dividing the heat range into heat ranges and configuring corresponding preset times for each heat range. A mapping relationship between heat and cooling time can be established through the values corresponding to the ranges. This method is simple, effective, easy to implement, and has strong visualization and flexibility. The tolerance of the ranges can be used to improve the robustness of the control system when configuring the cooling time, accommodate heat fluctuations and calculation errors of total heat, avoid control jitter, and improve the stability and reliability of the control process for determining the cooling time.
[0068] As an optional embodiment, determining the total heat generated during the current operation of the energy-consuming device includes:
[0069] Monitor the current during the current commissioning process of energy-consuming devices;
[0070] The total heat generated during this input process is determined based on the formula for calculating current and heat.
[0071] The formula for calculating heat is:
[0072] ;
[0073] in, This represents the total heat generated during this process. This represents the resistance value of the energy-consuming resistor in the energy-consuming device. This refers to the current generated during the current commissioning of the energy-consuming device. The time when energy-consuming devices are put into operation.
[0074] It is easy to understand that the total heat generated during a single activation of an energy-consuming device can be calculated from the current flowing through it. Specifically, the current refers to the current flowing through the energy-consuming module within the device, which can be implemented using an energy-consuming resistor. This application does not impose specific limitations on the particular current monitoring method; it can be achieved by connecting a current transformer or current sensor in series within the energy-consuming device. The current transformer sends the monitored current data to the control system, which has a pre-programmed heat calculation formula. The control system then calculates the total heat generated by each energy-consuming device during that activation. The calculation involves several methods. Current monitoring can be performed in real-time, with the current value sent to the control system. The control system then calculates the heat changes generated by the energy-consuming device in real-time, ultimately determining the total heat generated during the current operation. Alternatively, current can be monitored periodically by setting a specific cycle. The periodic monitoring results are sent to the control system, which calculates the heat changes generated by the energy-consuming device within one cycle. Finally, the total heat generated during the current operation is determined by summing the results from multiple cycles.
[0075] It should be noted that, taking the example of an energy-consuming device using an energy-consuming resistor as the energy-consuming module, the heat calculation formula is as follows: The resistance of the energy-consuming resistor is typically measured in ohms (Ω), the current during the activation of the energy-consuming device is typically measured in amperes (A), and the activation time is typically measured in seconds (s). By monitoring the current of the energy-consuming device during activation and combining this with integral calculations, the total heat can be calculated accurately, quantifying accumulated heat, avoiding errors caused by instantaneous fluctuations. This method is simple, effective, easy to implement, and adaptable to various complex operating conditions, accommodating the heating characteristics of multiple coupled factors. After the monitored current data is sent to the control system, the control system can also generate a current-time relationship curve for the energy-consuming device based on the relationship between the current data and time, and determine the total heat through methods such as area calculation.
[0076] Specifically, the total heat can be calculated by monitoring the current. Current detection can be achieved through external current transformers, which will not interfere with the normal operation of energy-consuming devices. Furthermore, the current data has strong real-time performance and fast response speed, which can effectively adapt to the dynamic heating scenarios of energy-consuming devices. The implementation cost is also relatively low. It can be combined with the control system to achieve integrated detection and control. It also has strong compatibility and versatility, making it convenient for different application scenarios.
[0077] See Figure 2 As shown, Figure 2 A flowchart illustrating another control method for an energy-consuming device provided by the present invention; as an optional embodiment, it further includes:
[0078] Receive the input command and determine the input quantity specified in the input command;
[0079] Identify the N energy-consuming devices that require the fewest activations from all energy-consuming devices in the first state, and control the activation of these N energy-consuming devices; N is the number of activations.
[0080] Understandably, in a scenario where several independent energy-consuming devices are set up in the entire energy-consuming system, the control system will determine how many (N) energy-consuming devices need to be put into operation based on the received input command. In order to ensure consistency among the energy-consuming devices, especially the consistency of their service life, the specific energy-consuming device to be put into operation each time will be determined based on the number of times each energy-consuming device has been put into operation. The number of times an energy-consuming device has been put into operation refers to the total number of times the energy-consuming device has been put into operation during the operation of the entire energy-consuming system. Each time, the energy-consuming devices with fewer times of operation will be put into operation first to ensure the consistency of the number of times each energy-consuming device has been put into operation.
[0081] It should be noted that this application does not impose specific limitations on the type and implementation method of the activation command. In DC transmission systems, the DC station control system typically determines the number of energy-consuming devices to be activated based on a comprehensive consideration of the actual power generation of the new energy system and the specific configuration of the energy-consuming devices. Then, it issues activation commands to the control systems of the energy-consuming devices so that the control systems can activate the corresponding number of devices. Each energy-consuming device in the energy-consuming system usually reuses the same control system, with one control system controlling the activation of multiple energy-consuming devices. Furthermore, due to the cooling time settings of the energy-consuming devices, the control system can only determine the devices to be activated from those in their first state. This application does not impose specific limitations on the specific method for determining the activation frequency N of each energy-consuming device; it can be implemented using a counter or similar method, where N is a positive integer.
[0082] Specifically, this embodiment provides a method for controlling the switching sequence of multiple energy-consuming devices. Combined with the control process for the cooling time of these devices, it effectively optimizes the switching sequence and cooling time. The entire control method optimizes the selection of the switching sequence and the self-locking time of the cooling mechanism after each action. On one hand, it prioritizes devices with fewer activations based on the total number of activations for each group of energy-consuming devices. On the other hand, by calculating the total heat generated by each group of energy-consuming devices and setting different cooling times based on the range of total heat generated, it quickly restores the activation capacity of the energy-consuming devices. Taking all factors into consideration, this method aims to extend the service life of the entire energy-consuming system and achieve accurate control and flexible switching of the energy-consuming devices.
[0083] As an optional embodiment, it also includes:
[0084] For any energy-consuming device, configure the number of times it is used;
[0085] After controlling the activation of N energy-consuming devices, the following is also included:
[0086] Increment the count value of each of the N energy-consuming devices by 1;
[0087] From all energy-consuming devices in the first state, determine the N energy-consuming devices that require the fewest activations, including:
[0088] Based on the count values of all energy-consuming devices in the first state, determine the N energy-consuming devices that have been used the least number of times from all energy-consuming devices in the first state.
[0089] It's easy to understand that the count value can be configured separately for each energy-consuming device. Each time an energy-consuming device is activated by the control system, the control system increments the corresponding count value by 1. The specific count value determines the number of times each energy-consuming device has been used. This application does not specifically limit the implementation method of the count value; it can be implemented by configuring a counter in the control system, or by directly setting a register corresponding to each energy-consuming device in the control system. After the control system issues an activation control command to an energy-consuming device, it directly increments the configured value of the corresponding register by 1. Generally, the initial value of the count value is set to zero.
[0090] It should be noted that after configuring the count value, the N energy-consuming devices with the fewest inputs can be determined by the count value corresponding to each energy-consuming device. Specifically, the count value corresponding to all energy-consuming devices in the first state can be determined, and then the count values corresponding to all energy-consuming devices in the first state can be sorted in ascending order. The energy-consuming devices corresponding to the top N count values of the sorted results are determined as the N energy-consuming devices with the fewest inputs, and the input is controlled in this operation.
[0091] As a specific embodiment, such as Figure 2 As shown, assuming the number of times the i-th group of energy-consuming devices is activated is denoted as Bi, after the control system receives the activation command, which requires the activation of N groups of energy-consuming devices, the system sorts the groups of energy-consuming devices that are allowed to be activated (i.e., those in the first state) according to their activation count. This determines the N groups of energy-consuming devices with the fewest activation counts. Then, the system triggers the activation control command, controlling the N groups of energy-consuming devices with the fewest activation counts. After these N groups of energy-consuming devices are activated, they send a successful activation signal back to the control system. The control system then increments the activation count of these N groups of energy-consuming devices by 1, Bi = Bi + 1 (i = 1, 2, ..., N). After these N groups of energy-consuming devices are activated, the control system calculates the total heat generated by any one group of energy-consuming devices. Then, the preset heat range corresponding to the total heat is determined by comparison, and the cooling time corresponding to the energy-consuming device is determined and recorded according to this correspondence. After the energy-consuming device completes the energy-consuming operation corresponding to this input, the energy-consuming device is controlled to remain in the second state where it is not allowed to be input according to the recorded cooling time, until the cooling time is reached to indicate that the cooling is over, and then the energy-consuming device is allowed to be input.
[0092] Specifically, the number of times an energy-consuming device is used can be counted by configuring the count value. This is simple, effective, easy to implement, and facilitates the unified management of multiple energy-consuming devices by the control system.

[0099] For a description of the control system for an energy-consuming device provided by the present invention, please refer to the embodiments of the control method for the energy-consuming device described above. The present invention will not be described again here.
[0100] See Figure 4 As shown, Figure 4This is a schematic diagram of the structure of an energy-consuming device provided by the present invention. To solve the above-mentioned technical problems, the present invention also provides an energy-consuming device, including a switch module, an energy-consuming module, and a control system as described above. The switch module and the energy-consuming module are connected in series, and both ends of the series circuit are respectively connected to a target power supply module. The output end of the control system is connected to the control end of the switch module.
[0101] The switch module is used to control the on or off of the device based on the control system, so as to determine whether the energy-consuming device is activated or not.
[0102] It is easy to understand that the energy-consuming device specifically includes a switching module, an energy-consuming module, and a control system. The control system controls whether the energy-consuming device is activated or deactivated by controlling the switching module to turn it on or off. When the switching module is on, the energy-consuming device is activated, the circuit between the energy-consuming device and the target power supply module is connected, and energy can be consumed. When the switching module is off, the energy-consuming device is deactivated, the circuit between the energy-consuming device and the target power supply module is disconnected, and the energy-consuming device does not work. The energy-consuming module is used to realize energy consumption. This application does not make any special limitations on the specific types and implementation methods of the switching module and the energy-consuming module. The switching module can be implemented using various types of switching devices, and the energy-consuming module can be implemented using energy-consuming resistors, etc. This application does not make any special limitations on the specific types and implementation methods of the target power supply module, including but not limited to new energy systems corresponding to DC transmission systems.
[0103] For an introduction to the energy-consuming device provided by the present invention, please refer to the embodiments of the control method of the energy-consuming device described above. The present invention will not be described again here.
[0104] As an optional embodiment, the target power supply module is an AC power supply module, and the switching module is a thyristor valve group;
[0105] The thyristor valve group includes a first thyristor and a second thyristor. The gates of the first thyristor and the second thyristor are both connected to the output terminal of the control system. The anode of the first thyristor is connected to the cathode of the second thyristor and serves as the first end of the thyristor valve group. The cathode of the first thyristor is connected to the anode of the second thyristor and serves as the second end of the thyristor valve group.
[0106] It is understandable that if the target power supply module is an AC power supply module, its output electrical energy exists in the form of alternating current. The direction of the alternating current current changes, therefore a thyristor valve group capable of bidirectional switching is needed as the switching module. Specifically, the thyristor valve group includes a first thyristor and a second thyristor, connected in parallel in opposite directions. When an energy-consuming device needs to be activated, the control system controls both thyristors to conduct; a preferred embodiment controls both thyristors to conduct simultaneously. When the direction of the alternating current is the first direction, its output current can flow through the conducting first thyristor to the energy-consuming module, thereby achieving energy consumption; when the direction of the alternating current is the second direction, its output current can flow through the conducting second thyristor to the energy-consuming module, thereby achieving energy consumption. This application does not specifically limit the specific types and implementation methods of the first and second thyristors; other switching devices supporting bidirectional switching can also be used, and it is not limited to the thyristor valve group disclosed in this embodiment.
[0107] As an optional embodiment, it also includes:
[0108] The current detection module, connected in series with the switch module and the energy consumption module, is used to detect the current during the activation of the energy consumption device.
[0109] It is easy to understand that, in order to facilitate the control system's calculation of the total heat generated during the activation of the energy-consuming device, a current detection module can be connected in series in the energy-consuming device to detect the current generated during the activation process. This application does not specifically limit the specific type and implementation method of the current detection module; it can be a current transformer, etc.
[0110] As a specific embodiment, such as Figure 4As shown, taking the target power supply module as an AC power supply module as an example, the energy consumption system is equipped with four sets of energy consumption devices. Each set of energy consumption devices uses a thyristor valve group as a switching module, a current transformer as a current detection module, and two energy consumption resistors to realize the energy consumption module. Considering that the power output of the AC power supply module is three-phase AC, each energy consumption device is equipped with three energy consumption structures corresponding to the three phases A, B, and C of the three-phase AC. Each energy consumption structure includes an energy consumption resistor, a thyristor valve group, a current transformer, and another energy consumption resistor connected in series. The first group of energy-consuming devices includes a first thyristor valve group composed of thyristors V11 and V12, a second thyristor valve group composed of thyristors V13 and V14, and a third thyristor valve group composed of thyristors V15 and V16.

The second thyristor valve group, together with energy-consuming resistors R23 and R24 and current transformer I22, forms the second energy-consuming structure of the second group of energy-consuming devices. The third thyristor valve group, together with energy-consuming resistors R25 and R26 and current transformer I23, forms the third energy-consuming structure of the second group of energy-consuming devices. The third group of energy-consuming devices includes a first thyristor valve group composed of thyristors V31 and V32, a second thyristor valve group composed of thyristors V33 and V34, and a third thyristor valve group composed of thyristors V35 and V36. The first thyristor valve group, together with energy-consuming resistors R31 and R32 and current transformer I31, forms the first energy-consuming structure of the third group of energy-consuming devices. The second thyristor valve group, together with energy-consuming resistors R33 and R34 and current transformer I32, forms the second energy-consuming structure of the third group of energy-consuming devices. The third thyristor valve group, together with energy-consuming resistors R35 and R36 and current transformer I33, forms the third energy-consuming structure of the third group of energy-consuming devices.The fourth group of energy-consuming devices includes a first thyristor valve group composed of thyristors V41 and V42, a second thyristor valve group composed of thyristors V43 and V44, and a third thyristor valve group composed of thyristors V45 and V46. The first thyristor valve group, together with energy-consuming resistors R41 and R42 and current transformer I41, forms the first energy-consuming structure of the fourth group of energy-consuming devices. The second thyristor valve group, together with energy-consuming resistors R43 and R44 and current transformer I42, forms the second energy-consuming structure of the fourth group of energy-consuming devices. The third thyristor valve group, together with energy-consuming resistors R45 and R46 and current transformer I43, forms the third energy-consuming structure of the fourth group of energy-consuming devices.
[0111] The control system is responsible for controlling, protecting, and monitoring the current of the energy-consuming device; the thyristor valve group is controlled by the control system to enable the energy-consuming device to be put into operation; the current transformer is responsible for monitoring the current flow and feeding back the monitored current data to the control system; the energy-consuming resistor consumes the surplus energy in the form of heat, thus realizing energy consumption.

Similar connections are required between the gates of other thyristors and the control system. Figure 4 The connecting lines are omitted. Figure 4 The diagram only shows the connections between current transformers I12, I22, I32, and I42 and the control system.
