[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Those skilled in the art will appreciate that embodiments of the present invention may be provided as methods, systems, or computer program products. Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0055] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatuses.

[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] An embodiment of the present invention provides a specific implementation of a performance monitoring component for an integrated gate-commutated thyristor.

[0058] Specifically, see Figure 1 The performance monitoring component of the integrated gate-commutated thyristor specifically includes the following contents:

[0059] The integrated gate-commutated thyristor 1 is cylindrical;

[0060] The spiral segment array 2, composed of a plurality of spiral segments 3, is evenly arranged on the circular periphery of the integrated gate-commutated thyristor, and is used to determine the current distribution of the integrated gate-commutated thyristor 1 to monitor the performance of the integrated gate-commutated thyristor 1 (the backend server determines the current distribution of the integrated gate-commutated thyristor 1 through the spiral segment array 2 to monitor the performance of the integrated gate-commutated thyristor 1).

[0061] From the above description, it can be seen that an embodiment of the present invention provides a performance monitoring component for an integrated gate-commutated thyristor, comprising: an integrated gate-commutated thyristor, which is cylindrical; a spiral segment array, composed of a plurality of spiral segments, evenly arranged on the circular periphery of the integrated gate-commutated thyristor, for determining the current distribution of the integrated gate-commutated thyristor to monitor the performance of the integrated gate-commutated thyristor.

[0062] The present invention can monitor the distribution of the internal current of the integrated gate-commutated thyristor in real time without interfering with the normal operation of the integrated gate-commutated thyristor, and evaluate the health status of the device in combination with an aging model.

[0063] In some embodiments of the present invention, preferably, the integrated gate-commutated thyristor 1 is a crimped IGCT, and its working principle is roughly as follows: when the IGCT is working, its conduction and shutdown are controlled by the gate signal. During the conduction process, the IGCT is similar to a traditional thyristor and can carry high current. When it needs to be turned off, the gate drive circuit quickly removes the carriers, causing the device to turn off quickly. The fast turn-off characteristics of the IGCT are mainly attributed to its integrated gate drive circuit and optimized internal structure. The characteristics and advantages of the IGCT include:

[0064] High Current and High Voltage Capabilities: IGCTs are capable of handling very high currents and voltages and are suitable for high power applications.

[0065] Low conduction loss: In the on state, the IGCT has a low conduction voltage drop, resulting in low conduction loss.

[0066] Fast switching: IGCT has fast switching capability and can complete the transition from on to off in a short time.

[0067] High reliability: Due to its rugged structure and high tolerance, IGCT exhibits high reliability in harsh industrial environments.

[0068] Simple drive circuit: Compared with traditional thyristors, the gate drive circuit of IGCT is simpler, which simplifies system design.

[0069] In some embodiments of the present invention, see Figure 2 as well as Figure 3 The spiral segment array 2 is composed of 8 spiral segments 3, each of which is evenly distributed on the circumference of the cylinder of the integrated gate-commutated thyristor, that is, each spiral segment 3 occupies a regional position of 45°.

[0070] In some embodiments of the present invention, a performance monitoring assembly for an integrated gate-commutated thyristor further includes:

[0071] The voltage monitoring module is used to monitor the induced voltage of each spiral segment to determine the current distribution.

[0072] In some embodiments of the present invention, see Figure 4 The present invention also provides a method for using the performance monitoring component applied to the above-mentioned integrated gate-commutated thyristor, the method comprising:

[0073] Step 100: monitoring the induced voltage of each spiral segment in real time;

[0074] Step 200: Determine the difference between the induced voltages of each spiral segment;

[0075] Step 300: monitoring the performance of the integrated gate-commutated thyristor according to the difference.

[0076] In some embodiments of the present invention, the induced voltage in step 100 refers to the voltage generated by the spiral segment due to the change of the external magnetic field or the change of the current. It is the result of electromagnetic induction. According to Faraday's law of electromagnetic induction, the magnitude of the induced voltage is related to the rate of change of the magnetic field and the relative motion of the conductor and the magnetic field.

[0077] For step 200 and step 300, if the current distribution through the integrated gate-commutated thyristor is balanced, the difference between the induced voltages of each spiral segment should be small; if the current distribution is uneven, the spiral induced voltage in certain areas will increase significantly, thereby monitoring the performance of the integrated gate-commutated thyristor.

[0078] In some embodiments of the present invention, see Figure 5 , step 300 comprises:

[0079] Step 301: determining the current distribution of the integrated gate-commutated thyristor according to the difference;

[0080] It is understandable that uneven current distribution may cause local overheating, which in turn affects the life and stability of the IGCT. On the other hand, the uniformity of current distribution directly affects the conduction loss of the IGCT. If the current is unevenly distributed, some areas may be subjected to higher current density, resulting in overheating and increased power loss.

[0081] Furthermore, the current distribution inside the IGCT can be predicted through numerical simulation and circuit simulation (such as finite element analysis and electromagnetic field simulation). These models can be optimized and adjusted according to different working conditions (such as load changes, voltage fluctuations, etc.).

[0082] Step 302: Monitor the performance of the integrated gate-commutated thyristor according to the current distribution.

[0083] In some embodiments of the present invention, see Figure 6 , a method for using a performance monitoring component of an integrated gate-commutated thyristor, further comprising:

[0084] Step 400: determining a standard current distribution according to a standard integrated gate-commutated thyristor;

[0085] Step 500: Calibrate the collected induced voltage of each spiral segment according to the standard current distribution.

[0086] Specifically, the collected induced voltage is calibrated by a preset standard current signal to ensure the accuracy of the data.

[0087] In some embodiments of the present invention, see Figure 7 , a method for using a performance monitoring component of an integrated gate-commutated thyristor, further comprising:

[0088] Step 600: Determine the change curve of the current distribution and time;

[0089] Step 700: generating an aging curve of the integrated gate-commutated thyristor according to the variation curve to predict the aging process of the integrated gate-commutated thyristor.

[0090] In step 600 and step 700, based on the sensed current distribution data, the system will combine the aging assessment algorithm to assess the health status of the IGCT device. The algorithm predicts the aging process of the device and generates an aging curve by analyzing the change of current distribution over time. The system can also make trend predictions based on historical data and provide an estimate of the remaining life of the device to help maintenance personnel to perform equipment maintenance or replacement in a timely manner.

[0091] In some embodiments of the present invention, see Figure 8, a method for using a performance monitoring component of an integrated gate-commutated thyristor, further comprising:

[0092] Step 800: Filter and process the collected signal to remove noise and obtain a clear current distribution signal.

[0093] From the above description, it can be seen that the method for using a performance monitoring component of an integrated gate-commutated thyristor provided by an embodiment of the present invention includes: first, monitoring the induced voltage of each spiral segment; then, determining the difference between the induced voltages of each spiral segment; and finally, monitoring the performance of the integrated gate-commutated thyristor according to the difference. The present invention has the following beneficial effects:

[0094] 1. Real-time monitoring: The system can monitor the internal current distribution state of the IGCT device in real time while it is running, without affecting the normal operation of the device.

[0095] 2. High-precision perception: Through the distributed structure of multiple spiral segments, it can accurately perceive the current distribution in different areas and promptly detect local aging or faults caused by current imbalance.

[0096] 3. Aging assessment and early warning: The system can not only sense the current state, but also predict the aging process of the device based on historical data, and provide fault early warning and life assessment.

[0097] 4. Compact structure: The short spiral segment array can be flexibly arranged and is suitable for IGCT devices of various shapes and structures without affecting the installation and connection of the equipment.

[0098] To further illustrate the present solution, the present invention provides a specific application example of a performance monitoring component of an integrated gate-commutated thyristor, which specifically includes the following contents.

[0099] The performance monitoring component of an integrated gate-commutated thyristor provided in a specific application example of the present invention has 8 spiral segments, which are evenly distributed around the IGCT, and the current flows in from the upper end of the IGCT and flows out from the lower end. Each spiral segment can sense the change of the surrounding current, and infer the distribution of the current inside the IGCT through the size and change of the induced voltage. If the current distribution is balanced, the voltage difference induced by each coil segment is small; if the current distribution is uneven, the spiral induced voltage in some areas will increase significantly.

[0100] First, each spiral segment is connected to the data acquisition platform, which is responsible for collecting the induced voltage data of each spiral segment in real time and analyzing the data. Its specific functions are as follows:

[0101] Data calibration: The collected induced voltage is calibrated through a pre-set standard current signal to ensure the accuracy of the data;

[0102] Data filtering and processing: Filter and process the collected signals to remove noise and obtain clear current distribution signals;

[0103] Next, based on the sensed current distribution data, the system will combine the aging assessment algorithm to evaluate the health status of the IGCT device. The algorithm predicts the aging process of the device by analyzing the change of current distribution over time and generates an aging curve. The system can also make trend predictions based on historical data and give an estimate of the remaining life of the device to help maintenance personnel perform equipment maintenance or replacement in a timely manner.

[0104] Based on the same inventive concept, the embodiments of the present application also provide a device for using a performance monitoring component of an integrated gate-commutated thyristor, which can be used to implement the method described in the above embodiments, such as the following embodiments. Since the principle of solving the problem by the device for using a performance monitoring component of an integrated gate-commutated thyristor is similar to the method for using a performance monitoring component of an integrated gate-commutated thyristor, the implementation of the device for using a performance monitoring component of an integrated gate-commutated thyristor can refer to the implementation of the method for using a performance monitoring component of an integrated gate-commutated thyristor, and the repeated parts will not be repeated. As used below, the term "unit" or "module" can be a combination of software and / or hardware that implements a predetermined function.
