[0034] In this embodiment, by real-time monitoring and dynamic adjustment of the power supply of non-main load circuits, the device can reduce unnecessary power consumption while ensuring the normal operation of key equipment in the data center. This refined management helps to improve energy utilization efficiency and reduce operating costs. The introduction of dynamic voltage compensation elements enables the main load circuit to be compensated in a timely and effective manner when facing voltage fluctuations, thereby ensuring the stable operation of the load equipment. This is particularly important for places such as data centers that have extremely high requirements for power supply stability, avoiding equipment failures and data loss caused by voltage fluctuations. The main controller quickly calculates and makes decisions based on the real-time current value, and quickly adjusts the state of the power electronic static switch through the switch control circuit. This high-speed response mechanism enables the system to quickly adapt to load changes, improving the flexibility and reliability of the entire data center. By reducing the power consumption of non-essential loads and stabilizing the voltage supply of the main loads, the device helps to reduce the workload and temperature fluctuations of the equipment, thereby extending the service life of various equipment in the data center. The device can dynamically allocate power based on real-time data to ensure that key loads can obtain sufficient power support when needed, while reducing the power waste of non-critical loads. This intelligent power distribution strategy helps to improve the overall operating efficiency of the data center.

[0036] In this embodiment, the Hall current sensor and the shunt are both high-precision current measuring elements. The Hall current sensor can accurately capture large current changes in the input power circuit through non-contact measurement, while the shunt is suitable for measuring smaller currents that may exist in each load circuit. This combination ensures that high-precision measurement can be achieved regardless of the current size. Different types of current measuring elements (Hall current sensor and shunt) are used to measure the input power circuit and each load circuit respectively, which reflects the wide applicability of the technical solution.

The digital ammeter is used as the output end of the measuring element to measure the analog The analog signal is converted into a digital signal and then transmitted to the main controller. This digital processing improves the signal's anti-interference ability and transmission efficiency, and also facilitates the main controller to perform subsequent data processing and analysis; the fast connection and transmission of the current measurement element with the digital ammeter and the main controller ensures the real-time collection and transmission of current data, which enables the main controller to perform real-time calculations and decisions based on the latest current data, improving the response speed and accuracy of the system; the high-precision current data provides the main controller with rich input information, enabling the data center load dynamic control device to perform more intelligent and refined control based on real-time current data, which helps to further improve the energy efficiency and load stability of the data center.

[0037] Preferably, the main controller includes a microprocessor, a memory and a communication interface, the microprocessor is used to execute control algorithms and logical judgments, the memory is used to store control algorithms, parameters and calculation results, and the communication interface is used to transmit and communicate data with external devices.

[0038] In this embodiment, the microprocessor is the core component of the main controller, responsible for executing complex control algorithms and logical judgments. Its high-performance computing capability ensures that the system can quickly respond to load changes, perform real-time calculations and decisions, and thus achieve dynamic control of the data center load; the memory is not only used to store control algorithms, but also to store related parameters and calculation results, which enables the main controller to flexibly adjust the control strategy according to different load conditions and system requirements to achieve more refined management. At the same time, the scalability of the memory also supports future upgrades and optimizations of control algorithms; the storage of control algorithms, parameters and calculation results by the memory ensures the security of these data. In the data center environment, data integrity and confidentiality are crucial. Through the secure storage mechanism of the memory, data leakage and tampering can be effectively prevented to ensure the stable operation of the system; the communication interface enables the main controller to The controller can carry out efficient data transmission and communication with external devices, including communication with internal devices such as current measurement elements, switch control circuits, dynamic voltage compensation elements, and communication with external systems such as data center management systems and monitoring centers.

The microprocessor can execute complex fault diagnosis algorithms, combine real-time data and historical records, and conduct a comprehensive health check on the system. Once an abnormality or fault is found, an alarm message is immediately sent to the external system through the communication interface so that the operation and maintenance personnel can handle it in time.

[0039] Preferably, the switch control circuit includes a logic gate circuit and a relay, the logic gate circuit is used to execute corresponding control logic according to the control command to control the relay, and the relay is used to control the on and off of the power electronic static switch of the non-main load circuit.

[0040] In this embodiment, the logic gate circuit has an extremely high switching speed and response capability, and can quickly execute the corresponding control logic according to the control command of the main controller. This fast response characteristic ensures that the power electronic static switch of the non-main load circuit can complete the on-off operation in a very short time, thereby meeting the high real-time requirements of the data center; the logic gate circuit can accurately parse the control command and control the relay according to the predetermined control logic. This accurate control avoids the occurrence of malfunction and misoperation, and ensures the reliability and stability of the switch control circuit; the relay, as a control element, has the function of electrical isolation. It can provide reliable isolation between the control circuit and the controlled circuit, prevent the direct transmission of current and voltage, and thus protect the safety and stability of the control circuit; the relay usually has a higher load capacity and can control the on-off of a larger current. In the data center load dynamic control device, the non-main load circuit may involve a larger current load. Therefore, the use of the relay can ensure the reliable on-off of the power electronic static switch in these cases; by programming and configuring the control logic of the logic gate circuit, the control strategy and control parameters can be flexibly set. This flexible configuration capability enables the switch control circuit to adapt to different application scenarios and control requirements.

[0041] Preferably, the power electronic static switch comprises a solid-state relay and an insulated gate bipolar transistor, and the solid-state relay and the insulated gate bipolar transistor are respectively used to control the on and off of non-main load circuits of different voltage levels in the data center.

[0042] In this embodiment, solid-state relays and IGBTs, as power electronic static switches, both achieve contactless switching. Compared with traditional mechanical relays, they avoid problems such as contact wear, arc generation and mechanical vibration, thereby improving the reliability and service life of the switch; solid-state relays and IGBTs both have extremely fast switching speeds and precise control capabilities. They can respond quickly to control signals and achieve rapid on-off of non-main load circuits. Such rapid response and precise control are crucial for dynamic management of data center loads and help achieve more refined power distribution and energy-saving effects; by adopting a combination of solid-state relays and IGBTs, the power electronic static switch can cover non-main load circuits of different voltage levels in the data center. Solid-state relays are suitable for low-voltage circuits, while IGBTs are suitable for low-voltage circuits. GBT is suitable for high-voltage circuits. The adaptability of this wide voltage range enables the power electronic static switch to meet the diverse load requirements of the data center. When controlling the on and off of non-main load circuits, the power electronic static switch can achieve smoother power regulation and reduce unnecessary power loss. Especially in the case of large load changes, by accurately controlling the on and off time of the power electronic static switch, energy consumption can be further reduced and energy utilization efficiency can be improved. The power electronic static switch can be seamlessly integrated with intelligent control devices such as the main controller to achieve functions such as remote monitoring, fault diagnosis and automatic adjustment. This intelligent control capability enables the data center load dynamic control device to respond to various load changes more flexibly and improve the overall performance and stability of the system.

[0043] Preferably, the dynamic voltage compensation element includes an energy storage element and a power electronic converter, the energy storage element is used to store and release electric energy, and the power electronic converter is used to convert direct current into alternating current.

[0044] In this embodiment, the dynamic voltage compensation element can provide instant voltage support when the grid voltage fluctuates through the storage and release of electric energy by the energy storage element. When the grid voltage drops, the energy storage element releases electric energy, which is converted into AC power by the power electronic converter and then injected into the system to compensate for the voltage drop. Conversely, when the grid voltage is too high, excess electric energy can be absorbed and stored in the energy storage element, thereby maintaining the stability of the load voltage. This real-time voltage compensation function significantly improves the voltage stability of the data center. In the process of converting DC power into AC power by the power electronic converter, high-precision voltage and frequency regulation can be achieved. Through advanced control algorithms, the power electronic converter can ensure that the output AC power waveform is smooth and the harmonic content is low, thereby improving the power quality of the data center, which is very important for protecting precision. The introduction of energy storage elements provides additional energy buffer for the system. When power supply is interrupted due to power grid failure or emergencies, the energy storage elements can immediately release electric energy to provide short-term power supply for key loads in the data center and ensure the continuous operation of the system. This capability enhances the resilience and reliability of the data center and reduces the risk of data loss and business interruption due to power outages. Dynamic voltage compensation elements are usually combined with intelligent control systems to realize functions such as remote monitoring, data analysis and automatic adjustment. By real-time monitoring of the voltage, current and other parameters of the power grid and load, the intelligent control system can optimize the charging and discharging strategies of the energy storage elements and the output parameters of the power electronic converter to achieve the best voltage compensation effect and energy utilization efficiency.

[0055] In this embodiment, the main controller can accurately evaluate the current overall load state of the data center by real-time analysis of the current values ​​of the input power circuit and each load circuit, which includes an accurate grasp of the load size, distribution and change trend. This accurate load state evaluation provides a solid foundation for subsequent power demand forecasting and control strategy formulation; based on historical data and current load status, the main controller uses a prediction algorithm to predict the change trend of power demand. This prediction capability enables the data center to prepare in advance before the power demand changes significantly, such as adjusting the power supply strategy, optimizing load distribution, etc., so as to ensure the stability and reliability of power supply. In addition, predicting power demand in advance also helps the data center to better plan and manage power resources and reduce operating costs; through in-depth analysis of load status and power demand, the main controller can calculate the optimal energy utilization plan, which includes priority sorting of different loads, adjustment of power supply strategies, and charge and discharge management of energy storage elements.
