Description

Technical Field

[0001] The invention relates to the field of power system monitoring and management, and in particular to an intelligent power monitoring and management system. Background Art

[0002] A data center is a place where computer servers, storage devices, network devices and other information technology hardware are stored and a stable operating environment is provided for these devices. It is responsible for the storage, calculation and information exchange of massive data. Once a data center loses power, it will cause a series of serious consequences.

[0003] The power supply and distribution system of a data center is the basic guarantee for the normal operation of the entire data center. Its main function is to distribute external power to various electrical equipment inside the data center in a stable and reliable manner, and to provide backup power support in the event of a city power failure, ensuring uninterrupted power supply to the data center.

[0004] Since data centers need to operate 24 hours a day, 365 days a year, the power supply and distribution system is in high-load operation for a long time. Therefore, it is very important to ensure the health of the power supply and distribution system of the data center so that it can operate stably and uninterruptedly.

[0005] However, the existing health monitoring and management methods for data center power supply and distribution systems still have some limitations and shortcomings in practical applications.

[0006] For example, the existing Chinese patent with publication number CN112345856A discloses a test method for a low-voltage power supply and distribution system in a data center. The devices that need to be distributed in the low-voltage power supply and distribution system in a data center are IT equipment and air conditioners. The IT equipment with the same power is replaced by a heater, and the heat after the heater is connected to the circuit is used to simulate the heat generated by the IT equipment during operation. The heater is dissipated by a fan to simulate the local heat dissipation of the IT equipment itself. The load is used to replace the IT equipment for testing, which reduces the test cost and reduces the loss when a failure occurs. The air conditioner has the functions of cooling and dehumidification. When the voltage provided is insufficient, the cooling and dehumidification effects will be deteriorated. The cooling and dehumidification effects of the air conditioner are monitored in real time by setting a thermometer and a hygrometer in the room. The real-time power of the heater is detected by a power detector. The result is obtained by comparing the measured data with the preset data. The test can be performed before the official power supply to ensure the stability of the low-voltage power supply system.

[0007] For example, the existing Chinese patent with authorization announcement number CN101718825B discloses a method for testing the low-voltage power supply and distribution system of a data center. The method uses a low-power rack-mounted heat load that can be installed in a cabinet to simulate the working state of a server, and treats the low-voltage power supply and distribution system of the data center as an organic whole. The equipment, centralized monitoring system and air-conditioning system in the low-voltage power supply and distribution system are simultaneously tested with load. Before the data center is put into use, this invention can detect hidden faults and disasters by conducting a comprehensive and systematic online test of the power supply and distribution system, and minimize the risk of power outages. This invention can not only effectively conduct joint commissioning of the power supply and distribution system, the air-conditioning system and the centralized monitoring system, but also test the three systems at the same time to shorten the test cycle and improve work efficiency.

[0008] The above-mentioned patents for the health management of the power supply and distribution system of the data center mostly conduct independent analysis of each electrical device or component in the power supply and distribution system, without considering the coordination and cooperation between the electrical devices or components in the power supply and distribution system and the monitoring of the coordinated operation between the electrical devices or combined parts. As a result, the existing health management system of the power supply and distribution system of the data center is not perfect and prone to regulatory loopholes, which in turn cannot better guarantee the normal operation of the equipment in the data center, thereby threatening the stability of the data center. Summary of the invention

[0025] It should be noted that, according to the different power supply sources, the power supply and distribution system of the data center has three power supply modes, namely, mains power supply, uninterruptible power supply and emergency generator power supply. The coordinated cooperation of the three power supply modes of the power supply and distribution system ensures uninterrupted power supply of the data center.
