[0003] Grid-side supercapacitor-based SVG devices are the latest cutting-edge technology in the flexible DC field, utilizing a "modular multilevel converter + supercapacitor" topology.

[0041] The specific implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] like Figure 2 、 Figure 3 As shown, the present invention proposes a compact super-capacity valve control system for a network-type converter valve, comprising: multiple valve control hosts, multiple super-capacity sub-modules and a chassis; multiple valve control hosts are integrated into one chassis and then connected to an external network-type device; multiple super-capacity sub-modules are connected to an external power grid;

[0044] Each of the valve-controlled hosts comprises: a valve-controlled host core board and a plurality of interface boards; the valve-controlled host core board is respectively connected to each of the interface boards, and each of the interface boards is respectively connected to some of the super-capacitor sub-modules in all of the super-capacitor sub-modules;

[0045] The valve control host core board is used to process the collected status data of each super-capacitor module to obtain a processing result of each super-capacitor module; generate a control signal for each super-capacitor module according to the processing result of each super-capacitor module; and distribute the control signal of each super-capacitor module to the corresponding interface board;

[0046] The interface board is used to control the super-capacitor module corresponding to the control signal according to the received control signal.

[0047] The aforementioned network-type device is used to control the valve control host, so that the valve control host controls the switching on or off of all super-capacitor modules; when the super-capacitor modules need to be charged, the power grid charges the super-capacitor modules; the compact super-capacitor valve control system of the network-type converter valve can include two identical valve control hosts that serve as backup for each other. Each valve control host consists of a valve control host core board and multiple interface boards;

[0048] Furthermore, the system further comprises: a plurality of monitoring hosts, and the valve control host core board in each of the valve control hosts is connected to one of the monitoring hosts.

[0049] The design architecture of the present invention optimizes the traditional complex four-layer design of the valve control of the modular multi-level converter into a two-layer design with the valve control host as one layer and the super-capacitor module as one layer. It is applied to the control of the compact super-capacitor valve control system of the network-type converter valve, which greatly reduces the hardware requirements of the chassis and reduces the hardware cost. At the same time, since a backplane with wiring can be set on the back of a chassis, multiple valve control host core boards can communicate with each other through the backplane, which increases the reliability of communication and the synchronization between the core boards of each valve control host. It greatly reduces the link delay of data transmission. It reduces the complexity of the overall system, reduces the probability of hardware problems, and improves the reliability of the system.

[0050] Furthermore, the system further includes: a plurality of super-capacity clusters, each of the interface boards is respectively connected to a portion of the super-capacity clusters among all the super-capacity clusters; and each of the super-capacity clusters is respectively connected to all the monitoring hosts.

[0051] As mentioned above, the valve control host communicates with the super-capacitor module and super-capacitor cluster respectively through the interface board; the super-capacitor module and super-capacitor cluster both send their own status information to the interface board and receive control commands from the interface board. After receiving the super-capacitor module and super-capacitor cluster information, the interface board sends the data to the valve control host core board for processing; the valve control host core board sends the processed commands to the interface board, which then distributes them to each super-capacitor module and super-capacitor cluster. The design of the compact super-capacitor valve control system of the meshed type converter valve refers to the design concept of the traditional modular multi-level converter valve control (MMC valve), while optimizing its complex control layer. The main difference between the compact super-capacitor valve control system of the meshed type converter valve and the traditional MMC valve is that the super-capacitor cluster is connected in parallel in the compact super-capacitor valve control system of the meshed type converter valve. Therefore, during control, the system must not only monitor and control the super-capacitor module, but also the super-capacitor cluster.

[0052] Furthermore, the system further comprises: an inverter;

[0053] Each of the ultra-capacitor modules is connected to the converter, and the converter is connected to the power grid;

[0054] The supercapacitor module is configured to store the energy of the converter in each of the supercapacitor clusters when the converter provides energy; and absorb energy from each of the supercapacitor clusters and send the energy to the converter when the converter needs energy.

[0055] The above, such as Figure 4As shown, the converter can be composed of multiple submodules, each of which is an H-bridge device consisting of four IGBTs (Insulated Gate Bipolar Transistors). T1-T4 are transistors, D1-D4 are diodes, SM is a submodule, and C is a capacitor.

[0056] Furthermore, the super-capacity cluster is used to send its own status information to each of the monitoring hosts and each of the valve control host core boards respectively;

[0057] The super-capacitor module is further configured to send its own status information to each of the valve-controlled host core boards;

[0058] The valve control host core board is further configured to convert the status information of each super-capacity cluster and / or each super-capacity submodule into status data of the corresponding super-capacity submodule after receiving the status information of each super-capacity cluster and / or each super-capacity submodule;

[0059] The monitoring host is configured to monitor the received status information of each super-capacity cluster;

[0060] The state data of the super-capacitor module includes: voltage state data of the super-capacitor module and temperature state data of the super-capacitor module.

[0061] As mentioned above, the monitoring host receives information from both the valve control host and all super-capacity clusters via optical fiber. The monitoring host receives data from the super-capacity submodules and monitors their status. Not only does it need to receive status information about the super-capacity submodules from the valve control host, it also needs to monitor the status of the super-capacity clusters.

[0062] Furthermore, the converter includes: a plurality of insulated gate bipolar transistors, and the plurality of insulated gate bipolar transistors are connected in a bridge manner.

[0063] Furthermore, if Figure 5 As shown, the system further includes: a plurality of supercapacitors, each of the supercapacitor submodules is connected in parallel with one supercapacitor;

[0064] The supercapacitor is used to store energy of the supercapacitor submodule connected in parallel with the supercapacitor.

[0065] As mentioned above, the monitoring host and valve control host are both equipped with dual power supplies. When one of the power supplies is damaged, the other power supply can still ensure the normal operation of the monitoring host and the valve control host. The valve control host can implement the startup strategy of the supercapacitor through software. The chassis of the compact supercapacitor valve control system of the meshed type converter valve can be equipped with a dual power supply configuration of the first power board and the second power board. The two power supplies use independent power supply wiring. When other factors cause one of the power supplies to lose power, the remaining power supply can still ensure the normal operation of the chassis, thereby improving the reliability of the system operation. Multiple supercapacitor modules are connected to the external power grid, and the power grid is used to power the supercapacitor modules, realizing the storage of energy of multiple supercapacitor modules and supercapacitors, facilitating the smooth operation of the system.

[0066] Furthermore, each of the super-capacitor modules is further configured to absorb the voltage of the power grid when all the super-capacitor modules are locked; and the plurality of super-capacitor modules are further configured to perform voltage-balanced charging after the voltage absorbed by each super-capacitor module stabilizes.

[0067] The core control part of this system architecture is the valve control host, which is designed with multiple redundancy that is completely consistent with multiple valve control hosts. The compact super-capacity valve control system of the network-type converter valve of the present invention is coordinated with the pole control that participates in the control of the power system. The valve control host is mainly composed of two boards: the valve control host core board and the interface board. The valve control host core board is responsible for data transmission with the pole control through optical fiber. The communication protocol is Gigabit Ethernet protocol, which mainly receives the modulation wave and other control signals issued by the pole control. After the valve control host core board parses the modulation wave data, it calculates the on / off state required by each super-capacitor module and each IGBT at this time through the voltage equalization algorithm, NLM (Nearest Level Modulation, nearest level approach modulation) algorithm, circulation suppression and other algorithms, and packages these states according to the corresponding converter bridge arm and the corresponding super-capacitor module and distributes them to the corresponding interface board. After the interface board receives the data, it sends it directly to the super-capacitor module through optical fiber to perform on / off control of the IGBT, and the super-capacitor cluster performs protection control. The valve control host needs to receive status information reported by the super-capacitor module and the super-capacitor cluster for timely control. Therefore, both the super-capacitor module and the super-capacitor cluster send status data to the interface board, which integrates the data and then sends it to the valve control host core board for data processing.

[0068] like Figure 6 As shown in the figure, when the input DC voltage direction is fixed, the supercapacitor module and supercapacitor are charged in both the on and locked states, and charging is stopped in the off state. That is, when IGBT1 is turned on and IGBT2 is turned off, the supercapacitor module and supercapacitor are charged, and charging stops when IGBT1 is turned off and IGBT2 is turned on.

[0069] When using the system of the present invention, the input conditions are first designed. The branch where the supercapacitor is located can have a total of N supercapacitor modules and connected supercapacitors. The target operating voltage of a single supercapacitor is Upu, and the total input DC voltage is Udc.

[0070] Therefore, it can be concluded that if you want to use the total DC voltage Udc to charge a single supercapacitor to the target operating voltage Upu, you need to put n = (Udc / Upu) supercapacitor modules into charge. When designing, please note that N needs to be greater than n.

[0071] According to the above principle, if Figure 7 As shown, the supercapacitor startup process is as follows: First, under the control of the grid-type device, the compact supercapacitor valve control system of the grid-type converter valve provides a stable and elevated DC voltage input. The valve control host then locks all supercapacitor modules, allowing the supercapacitor modules and supercapacitors to absorb the grid's DC bus voltage for charging. When the DC input voltage stabilizes, the valve control host initiates an active charging control strategy, charging N supercapacitor modules. Simultaneously, a voltage balancing strategy is initiated, switching between lower-voltage supercapacitor modules and higher-voltage ones. This rotation continues until all supercapacitor modules reach a similar voltage level and are within ±5% of the target operating voltage (Upu). At this point, the supercapacitor modules and supercapacitors are considered fully charged and ready for unlocking, thus completing the supercapacitor startup process. The monitoring host simultaneously receives information from multiple valve control hosts and all supercapacitor clusters to monitor the entire system. Supercapacitor cluster information is transmitted via the supercapacitor modules to the interface board, which aggregates it to the valve control host core board, which then sends it to multiple monitoring hosts.

[0072] The system of the present invention refers to the design concept of traditional modular multi-level converter valve control and solves its main shortcomings at the same time, providing a compact super-capacity valve control system design for a mesh-type converter valve. The compact super-capacity valve control system design for a mesh-type converter valve combines the traditional valve control host, bridge arm control chassis and interface chassis into one chassis, and the boards using the valve control host core board and the interface board no longer communicate through optical fiber, but through differential signals on the backplane, thereby reducing the design in hardware. In terms of software, the main control and protection functions such as circulation suppression, phase balance, NLM algorithm, bridge arm protection, etc. are implemented by the valve control host core board, and the interface board is responsible for realizing the control and status upload of super-capacity sub-modules and super-capacity clusters.

[0073] The core function of the valve-controlled host computer in controlling the supercapacitor is to implement the supercapacitor's startup strategy, namely, ensuring that the voltages of the supercapacitor submodules and supercapacitor reach target values. A prerequisite for supercapacitor startup is that a stable DC voltage is connected to both the positive and negative terminals of the supercapacitor. In this embodiment of the present invention, the MMC valve converts the AC power supply into a stable DC voltage, which is then supplied to the supercapacitor valve.

[0074] After the supercapacitor receives stable DC power, the valve-controlled host computer begins to control the supercapacitor charging when it receives a start signal. During charging, the valve-controlled host computer switches the supercapacitor module between on and off states, causing each supercapacitor module and the connected supercapacitor to charge and discharge, bringing the supercapacitor module and supercapacitor to the target voltage.

[0075] Those skilled in the art should be aware that the complexity of the existing four-layer design significantly increases the probability of problems during the R&D and field commissioning phases, reducing the reliability of normal equipment operation. By referencing the traditional modular multilevel converter valve control design, this streamlined multi-layer design significantly reduces the complexity of the valve control system, saving hardware costs and on-site space, and improving the cost-effectiveness and reliability of the valve control design. Furthermore, by reducing the number of layers in the architecture, the overall valve control link latency is significantly reduced. Compared to traditional architectures, the internal link latency of the valve control is reduced by approximately 60-70%. This significantly reduces the overall control cycle and improves the control effectiveness of the valve control system. Furthermore, the design takes into account the specific characteristics of the supercapacitor submodules and transmits supercapacitor cluster information to the valve control host via optical fiber for control and protection. This ensures the safe and stable operation of the supercapacitor cluster. A supercapacitor startup strategy has been designed to ensure safe and stable supercapacitor operation. The chassis power supply incorporates a dual power supply configuration, with two power supplies connected using independent wiring. If one power supply fails due to other factors, the remaining power supply can still ensure normal operation of the chassis, improving system reliability. At the monitoring level, the status of the over-capacity cluster is monitored and displayed separately, which makes it easier for equipment operation and maintenance personnel to understand the status of the over-capacity cluster.

[0079] Step 2: Using the interface board, according to the received control signal, control the super-capacitor module corresponding to the control signal.
