Description

Technical Field

[0001] This invention belongs to the field of flexible DC transmission technology, specifically relating to a method for controlling the energy consumption time of an IGCT energy-consuming device and related equipment. Background Technology

[0002] With the booming development of the offshore wind power industry, flexible DC transmission technology has demonstrated significant advantages in offshore wind power grid connection applications due to its control flexibility. During offshore wind power grid connection, the system ride-through problem when an onshore AC side fails urgently needs to be addressed. Currently, the commonly used solution in the industry is to configure DC energy dissipation devices, with two main technical approaches: distributed and centralized. The distributed approach is consistent with the flexible DC converter valve technology, while the centralized approach uses multiple switching components connected in series, relying on the simultaneous operation of the switches to dissipate energy.

[0003] However, during the operation of centralized IGCT (Integrated Gate Commutated Thyristor) energy dissipation devices, components such as the main resistor, module resistor, and IGCT devices generate a large amount of heat when consuming energy. Due to the use of natural heat dissipation, the heat dissipation rate is much lower than the generation rate. Over time, continuous heat accumulation will lead to overheating and damage to the components. To avoid this situation, it is necessary to constrain the total energy consumption time that the energy dissipation device can accumulate in a short period of time, but existing technologies have not yet developed an effective method for calculating and controlling the energy consumption time.

[0004] It is evident that there is a lack of an effective control method to address the problem of overheating and damage to energy-consuming devices and resistors due to excessively long energy consumption times during natural heat dissipation. Summary of the Invention

[0005] This invention provides a method and related equipment for controlling the energy consumption time of an IGCT energy-consuming device. The method clarifies the energy consumption time calculation strategy, calculation method, and exit strategy after the energy consumption time reaches the limit, effectively solving the problem of overheating and damage to the device due to excessive energy consumption time when the energy-consuming device and energy-consuming resistor are naturally cooled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A method for controlling the energy consumption time of an IGCT energy-consuming device includes: Real-time monitoring of the operating status of the IGCT energy-consuming device; the operating status includes energy-consuming input status, energy-consuming short-term output status, and energy-consuming output status. Within a preset sliding window period, the cumulative energy consumption state duration of the IGCT energy-consuming device is counted using a sliding window algorithm; wherein, the cumulative energy consumption state duration is the sum of the total duration of the energy consumption input state counted in the sliding window and the total duration of the energy consumption short-term exit state counted in the sliding window. The cumulative energy consumption period of the IGCT energy-consuming device is continuously counted until the cumulative energy consumption period reaches the preset maximum energy consumption period or the IGCT energy-consuming device meets the exit conditions, at which point the IGCT energy-consuming device is immediately switched to the energy consumption exit state.

[0007] Furthermore, before the real-time monitoring of the operating status of the IGCT energy-consuming device, the following steps are included: The working state of the IGCT energy-consuming device is divided into energy-consuming input state, energy-consuming short-term output state, and energy-consuming output state; wherein, the energy-consuming short-term output state is the output state between two consecutive energy-consuming input states, and the duration of the energy-consuming short-term output state is less than a preset energy-consuming output duration threshold.

[0008] Furthermore, the step of using a sliding window algorithm to calculate the cumulative energy consumption state duration of the IGCT energy-consuming device within a preset sliding window period includes: Within the preset sliding window cycle, when the IGCT energy consumption device is started, the duration corresponding to the energy consumption state is included in the sliding window until the IGCT energy consumption device stops working. When restarting the IGCT energy consumption device, the duration corresponding to this energy consumption state will be counted in the sliding window again; Specifically, the IGCT energy-consuming device is considered to be in a non-energy-consuming state when it stops working. If the duration of the non-energy-consuming state is less than the preset energy-consuming exit duration threshold, then the current non-energy-consuming state is determined to be a short-term energy-consuming exit state. When the IGCT energy-consuming device is restarted, the duration of the short-term energy-consuming exit state is included in the sliding window. Otherwise, the current non-energy-consuming state is determined to be an energy-consuming exit state, and the duration of the energy-consuming exit state is not included in the sliding window. The cumulative energy consumption state duration of the IGCT energy consumption device is obtained by summing the duration of each energy consumption input state and the duration of each energy consumption short-term exit state.

[0009] Furthermore, the continuous counting of the cumulative energy consumption state duration of the IGCT energy-consuming device until the cumulative energy consumption state duration reaches the preset maximum energy consumption duration or the IGCT energy-consuming device meets the exit conditions, and then controlling the IGCT energy-consuming device to immediately switch to the energy consumption exit state, includes: Continuously monitor the cumulative energy consumption duration of IGCT energy-consuming devices; When the preset maximum energy consumption time reaches the cumulative energy consumption state time, or when it is determined that the IGCT energy consumption device meets the exit conditions, an energy consumption exit signal is output, so as to control the IGCT energy consumption device to immediately switch to the energy consumption exit state according to the energy consumption exit signal.

[0010] Further, the step of outputting a power consumption exit signal when it is determined that the IGCT power consumption device meets the exit conditions, and then controlling the IGCT power consumption device to immediately switch to the power consumption exit state based on the power consumption exit signal, includes: Determine whether the IGCT energy-consuming device meets the conditions for reactivation: If the IGCT energy-consuming device meets the conditions for restarting, then control the IGCT energy-consuming device to be turned on; otherwise, prohibit the IGCT energy-consuming device from being turned on. The condition for reactivation is that the sum of the expected reactivation time of the IGCT energy-consuming device and the cumulative energy consumption state time does not exceed the preset maximum energy consumption time.

[0011] Furthermore, the estimated duration for the IGCT energy-consuming device to be put back into operation is obtained based on historical data combined with current operating conditions or based on the requested energy consumption duration.

[0012] Further, the continuous counting of the cumulative energy consumption state duration of the IGCT energy-consuming device until the cumulative energy consumption state duration reaches the preset maximum energy consumption duration or the IGCT energy-consuming device meets the exit conditions, and then controlling the IGCT energy-consuming device to immediately switch to the energy consumption exit state, includes: If the duration of the IGCT energy-consuming device in the energy-consuming off state exceeds the preset cooling time, the cumulative energy-consuming state duration will be reset to zero; the cumulative energy-consuming state duration will be recalculated the next time the IGCT energy-consuming device is put into operation.

[0013] An energy consumption duration control system for an IGCT energy dissipation device includes: The status monitoring module is used to monitor the working status of the IGCT energy-consuming device in real time; the working status includes energy-consuming input status, energy-consuming short-term output status, and energy-consuming output status. The duration statistics module is used to calculate the cumulative energy consumption state duration of the IGCT energy-consuming device within a preset sliding window period using a sliding window algorithm; wherein, the cumulative energy consumption state duration is the sum of the total duration of the energy consumption input state included in the sliding window and the total duration of the energy consumption short-term exit state included in the sliding window. The control module is used to continuously count the cumulative energy consumption state duration of the IGCT energy-consuming device until the cumulative energy consumption state duration reaches the preset maximum energy consumption duration or the IGCT energy-consuming device meets the exit conditions, and then controls the IGCT energy-consuming device to immediately switch to the energy consumption exit state.

[0014] An energy consumption duration control device for an IGCT energy-consuming device includes: Memory, used to store computer programs; A processor is used to implement the steps of the above-described IGCT power consumption device power consumption duration control method when executing the computer program.

[0015] A computer-readable storage medium storing a computer program, which, when executed by a processor, is used to implement the steps of the above-described method for controlling the energy consumption duration of an IGCT energy-consuming device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a method for controlling the energy consumption duration of an IGCT energy-consuming device. By monitoring the operating status of the IGCT energy-consuming device in real time—specifically, energy consumption input, short-term energy consumption withdrawal, and energy consumption withdrawal—a sliding window algorithm is used to calculate the cumulative energy consumption duration within a preset sliding window period. Specifically, the energy consumption input and short-term energy consumption withdrawal states are included in the total duration of the sliding window, and this calculation continues until the cumulative duration reaches a preset maximum energy consumption duration or meets the withdrawal condition. At this point, the control device immediately switches to the energy consumption withdrawal state. The sliding window algorithm dynamically tracks the effective energy consumption time of the device, incorporating the energy consumption input and short-term energy consumption withdrawal states—that is, the high heat generation stage and the residual heat accumulation stage—into the cumulative duration, thereby quantifying the total heat generation. By limiting the upper limit of the cumulative duration, it ensures that the heat accumulation rate does not exceed the natural heat dissipation capacity, avoiding excessive component temperature rise due to heat generation continuously exceeding dissipation. This method effectively prevents device overheating damage, improves device operational reliability, achieves intelligent energy consumption control, and solves the heat accumulation problem without relying on external heat dissipation measures.

Detailed Implementation

[0018] To further understand the content of this invention, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0019] The technical terms involved in this invention are explained below: IGCT: short for integrated gate-commutated thyristor.

[0020] For example, such as Figure 2 As shown, this embodiment also provides a method for controlling the energy consumption time of an IGCT energy-consuming device, including the following steps: Real-time monitoring of the operating status of the IGCT energy-consuming device; the operating status includes energy-consuming input status, energy-consuming short-term output status, and energy-consuming output status. Within a preset sliding window period, the cumulative energy consumption state duration of the IGCT energy-consuming device is counted using a sliding window algorithm; wherein, the cumulative energy consumption state duration is the sum of the total duration of the energy consumption input state counted in the sliding window and the total duration of the energy consumption short-term exit state counted in the sliding window. The cumulative energy consumption period of the IGCT energy-consuming device is continuously counted until the cumulative energy consumption period reaches the preset maximum energy consumption period or the IGCT energy-consuming device meets the exit conditions, at which point the IGCT energy-consuming device is immediately switched to the energy consumption exit state.

[0021] In this embodiment, before real-time monitoring of the IGCT energy-consuming device's operating status, the device's operating status is divided into energy-consuming input state, energy-consuming short-term output state, and energy-consuming output state. The energy-consuming short-term output state is the output state between two consecutive energy-consuming input states, and its duration is less than a preset energy-consuming output duration threshold. It can be seen that this method clearly divides the operating status into energy-consuming input state, energy-consuming short-term output state, and energy-consuming output state before real-time monitoring. The energy-consuming short-term output state is defined as the output stage between two consecutive input states with a duration less than a preset threshold. This design aims to accurately distinguish between brief interruptions in heat accumulation and complete heat dissipation, avoiding misjudging short-term output as having no thermal impact, thus more accurately accounting for residual heat contribution, ensuring that the statistics of the cumulative energy consumption state duration are more consistent with thermodynamic reality, and improving the reliability of overheat protection.

[0022] In this embodiment, within a preset sliding window period, the cumulative energy consumption state duration of the IGCT energy-consuming device is statistically analyzed using a sliding window algorithm, including: Within a preset sliding window period, when the IGCT energy-consuming device is started, the duration corresponding to the energy-consuming state is included in the sliding window until the IGCT energy-consuming device stops working; when the IGCT energy-consuming device is restarted, the duration corresponding to this energy-consuming state is again included in the sliding window; the stage when the IGCT energy-consuming device stops working is considered a non-energy-consuming state; if the duration corresponding to the non-energy-consuming state is less than the preset energy-consuming exit duration threshold, then this non-energy-consuming state is determined to be a short-term energy-consuming exit state, and when the IGCT energy-consuming device is restarted, the duration corresponding to the short-term energy-consuming exit state is included in the sliding window; otherwise, this non-energy-consuming state is determined to be an energy-consuming exit state, and the duration corresponding to the energy-consuming exit state is not included in the sliding window; the cumulative energy-consuming state duration of the IGCT energy-consuming device is obtained by summing the duration of each energy-consuming state included in the sliding window and the duration of each short-term energy-consuming exit state included in the sliding window. This method provides a statistical process for the sliding window algorithm, including counting the energy consumption input time at startup and the input time at restart. If the stop phase is shorter than a preset threshold, it is considered a short-term energy consumption exit state and counted in the sliding window; otherwise, it is considered an energy consumption exit state and not counted. Finally, all counted times are accumulated. The principle is to identify and quantify the residual heat during the short-term exit period, avoid statistical neglect of the real heat load, and ensure that the accumulated time fully reflects the heat accumulation trend, thereby optimizing the accuracy of heat management and preventing the risk of overheating.

[0023] In this embodiment, the cumulative energy consumption state duration of the IGCT energy-consuming device is continuously counted until the cumulative energy consumption state duration reaches the preset maximum energy consumption duration or the IGCT energy-consuming device meets the exit conditions. Then, the IGCT energy-consuming device is immediately switched to the energy consumption exit state, including: The method continuously tracks the cumulative energy consumption duration of the IGCT energy-consuming device. When the preset maximum energy consumption duration reaches the cumulative energy consumption duration, or when the IGCT energy-consuming device meets the exit conditions, an energy consumption exit signal is output. Based on this signal, the IGCT energy-consuming device is immediately switched to the energy consumption exit state. This method, while continuously tracking the cumulative energy consumption duration, immediately outputs a signal to control the device to switch to the energy consumption exit state once it equals the preset maximum energy consumption duration or meets the exit conditions. Its principle lies in implementing a real-time threshold triggering mechanism to ensure rapid response at the heat accumulation critical point, avoiding delays that could lead to excessive heat, thereby improving the decision-making speed of the control system and the equipment protection efficiency.

[0024] For example, generally speaking, the exit conditions are usually issued by the control system. If the entire system does not need the IGCT energy-consuming device in the current stage of monitoring, it will directly issue an exit command, that is, an energy-consuming exit signal.

[0025] In this embodiment, after controlling the IGCT energy consumption device to immediately switch to the energy consumption shutdown state according to the energy consumption shutdown signal, the method further includes: The method determines whether the IGCT power-consuming device meets the reactivation conditions: if the IGCT power-consuming device meets the reactivation conditions, it controls the IGCT power-consuming device to be activated; otherwise, it prohibits the IGCT power-consuming device from being activated. The reactivation condition is that the sum of the expected reactivation time of the IGCT power-consuming device and the cumulative power consumption state time does not exceed the preset maximum power consumption time. After the IGCT power-consuming device switches to the power consumption off state, this method further determines whether the reactivation conditions are met (i.e., the sum of the expected activation time and the cumulative power consumption state time does not exceed the preset maximum power consumption time), and controls activation or prohibition accordingly. The principle is to decide to reactivate after assessing the residual heat effect, to prevent the superposition of new loads before the heat is fully dissipated, which would lead to overheating and deterioration, thereby extending the device life and ensuring continuous operation. It should be noted that the estimated time for the IGCT energy-consuming device to be put back into operation is based on historical data combined with current operating conditions or on the requested energy consumption time. By determining the estimated time for re-entry based on historical data combined with current operating conditions or by directly using the requested energy consumption time, a flexible data source is provided to adapt to changing operating conditions, ensuring that the re-entry decision is more adaptable and accurate, avoiding the risk of overheating caused by estimation errors, and improving the robustness and practicality of the control method.

[0026] In this embodiment, after controlling the IGCT energy-consuming device to immediately switch to the energy-consuming shutdown state, the method further includes: if the duration of the IGCT energy-consuming device switching to the energy-consuming shutdown state is longer than the preset cooling time, then the cumulative energy-consuming state duration is reset to zero; when the IGCT energy-consuming device is put into operation again, the cumulative energy-consuming state duration is recalculated. It can be seen that after the IGCT energy-consuming device switches to the energy-consuming shutdown state and the duration exceeds the preset cooling time, the cumulative energy-consuming state duration is reset to zero and recalculated when it is put into operation again. The purpose is to: set a sufficient cooling period to completely dissipate heat accumulation, avoid historical data from interfering with the new cycle through the reset mechanism, ensure that heat management starts from the beginning, thereby supporting the safe operation of the device in cycles and simplifying the control logic.

[0027] For example, a specific application of the control method provided in this embodiment has been carried out, and the implementation effect is as follows. Figure 1 As shown, the details are as follows: In application examples, combined with Figure 1 As shown, when the non-input period after energy consumption is initiated is greater than 500ms, the energy consumption working state switches to the energy consumption exit state; when the non-input period between two consecutive energy consumption initiation actions is less than 500ms, this non-input period belongs to the energy consumption short-term exit state. The sliding window period for calculating the energy consumption duration is 20 minutes, and the energy consumption duration constraint is set to 1.5s.

[0028] As can be seen from the above settings, within a 20-minute sliding window cycle, the cumulative energy consumption state duration is the sum of the energy consumption input duration and the energy consumption short-term exit duration, and the sum must satisfy ≤1.5s; that is, the preset maximum energy consumption duration. Figure 1 As can be seen from the top to the bottom of the diagram, these represent the energy consumption input action, the actual cumulative energy consumption state duration over 20 minutes, and the energy consumption duration within the 20-minute sliding window cycle. The energy consumption input action diagram shows that the non-input state duration between two consecutive energy consumption input actions is less than 500ms, therefore all can be identified as short-term energy consumption exit states, and the duration corresponding to these short-term exit states is included in the energy consumption duration. The actual cumulative energy consumption state duration over 20 minutes shows that when the cumulative energy consumption state duration is 1.5s, the system is in an energy consumption input state; after accumulating to 1.5s, the energy consumption immediately transitions to an energy consumption exit state. Within the 20-minute sliding window cycle, the energy consumption duration within the sliding window is 1.491s when the actual cumulative energy consumption state duration reaches 1.5s. After exiting the energy consumption state, a 9ms step into the sliding window brings the energy consumption duration within the sliding window to 1.5s.

[0029] like Figure 3 As shown, this embodiment also provides a power consumption duration control system for an IGCT power consumption device, including: a status monitoring module for real-time monitoring of the operating status of the IGCT power consumption device; the operating status includes a power consumption input state, a power consumption short-term exit state, and a power consumption exit state; a duration statistics module for calculating the cumulative power consumption state duration of the IGCT power consumption device using a sliding window algorithm within a preset sliding window period; wherein the cumulative power consumption state duration is the sum of the total duration of the power consumption input state included in the sliding window and the total duration of the power consumption short-term exit state included in the sliding window; and a control module for continuously calculating the cumulative power consumption state duration of the IGCT power consumption device until the cumulative power consumption state duration reaches a preset maximum power consumption duration or the IGCT power consumption device meets the exit conditions, and then controlling the IGCT power consumption device to immediately switch to the power consumption exit state.

When this cumulative duration reaches a preset maximum power-consuming duration or meets the withdrawal conditions, the device is immediately controlled to switch to the power-consuming withdrawal state. Its core principle lies in accurately quantifying the device's thermal accumulation process by precisely dividing the short-term withdrawal state and including it in the cumulative duration, covering both the high-heat-generating stage and the residual heat-affected stage. Simultaneously, it combines rapid response at the withdrawal critical point, safety verification before re-input, and a duration reset mechanism after sufficient cooling to construct a closed-loop thermal management logic. This control method significantly improves the device's safety in natural heat dissipation scenarios, avoiding device overheating damage caused by continuous heat accumulation. Furthermore, intelligent state recognition and dynamic control optimize operational continuity, ultimately achieving reliable and adaptive power consumption duration management without the need for additional cooling devices.
