In the prior art, there has been a system for monitoring each power supply unit of a data center. Specifically, in these existing monitoring systems, these power supply units are monitored by providing separate control units for each power supply unit.

For example, the generator set is usually equipped with an independent automatic control system, which is generally programmed by a Programmable Logic Controller (PLC). It is mainly responsible for the parallelization of the generators in the generator set and the split-output circuit breaker after the parallel machine. control. The start-up and exit of some data center generators require manual operation by the operation and maintenance personnel, and the degree of automation is low.

The automatic monitoring system of the medium voltage power distribution module is usually realized by the medium voltage power distribution cabinet manufacturer through the integrated protection device with its own programming tool. At the same time, the medium voltage power distribution system can be configured to operate the medium voltage power distribution system. Display and remote manual operation of the circuit breaker in the medium voltage power distribution module.

The automatic monitoring system of the low-voltage power distribution module usually implements a small number of automatic switching functions by the manufacturer of the low-voltage power distribution module by installing a PLC monitoring system in the power distribution cabinet of the low-voltage power distribution module.

For end power or distribution equipment, such as Uninterruptible Power Supply (UPS), High-Voltage Direct Current (HVDC) equipment, column head cabinets, Power Distribution Units (PDUs), etc. The automatic control of the electric equipment usually does not require external control, and the equipment itself automatically controls according to the operating state. The power monitoring system only needs to display the operating state of the above equipment in the system, and the function is usually implemented by the power environment monitoring system.

The existing monitoring system as described above has the following problems:

(1) There is no communication between the monitoring systems of each power supply unit, and the operation is isolated, and the coordination between the entire monitoring systems cannot be achieved.

(2) The operation of the monitoring system of each power supply unit is separate, and it is easy to cause invalid action and repeated action, resulting in multiple switching of the end. In severe cases, the system may be short-circuited.

(3) The monitoring system of each power supply unit cannot see the current status of the entire monitoring system and needs to be presented by an external third-party platform.

(4) The current automatic control system for medium voltage power distribution is usually realized by integrated protection devices, and integrated The main function of the protection device is to implement protection functions, such as protection against abnormal conditions in the circuit (circuit short circuit, open circuit, lack of equality), which has almost no control function.

The data center intelligent power monitoring system and the monitoring method of the embodiments of the present application aim to solve one or more technical problems as described above by cooperatively controlling the power supply units of the data center.

Referring to FIG. 1, a schematic structural diagram of a data center intelligent power monitoring system 100 according to an embodiment of the present application is shown.

The data center intelligent power monitoring system 100 can include at least one power supply unit 111 and a monitoring unit 120. The power supply unit 111 is used to provide power supply to the electrical equipment. The monitoring unit 120 is connected to the power supply unit 111 for collecting operating parameters of the power supply unit 111 and determining the switching timing of each power supply unit 111 based on the operating parameters.

Data centers typically include a large number of electrical devices, such as servers, storage devices, and other infrastructure devices that require power. Since the data center is running and/or storing a large amount of data (such as user data, etc.), once the electrical equipment is powered down, it may result in the loss of data, causing incalculable serious consequences.

The data center intelligent power monitoring system 100 of the present embodiment collects the operating parameters of each power supply unit 111 through the monitoring unit 120, and can obtain the running status of each power supply unit 111 in real time, and determine whether the running state is normal. The switching timing of the switching elements of the power supply unit 111 is controlled to ensure that the electrical equipment receives a normal power supply, thereby ensuring normal operation and/or storage of data.

In some implementations, in the data center intelligent power monitoring system 100 of the present embodiment, the monitoring unit 120 may include at least one sub-control unit 121 and a monitoring platform 122 connected to each sub-control unit.

In addition, the sub-control unit 121 can also be used to control the on and off of the circuit breaker of the corresponding power supply unit 111 based on the switching timing.

Here, the operating parameters collected by each sub-control unit 121 may include, for example, the voltage and current of the power supply unit 111 connected thereto (for example, the voltage, current, or any node position in the power supply unit 111). At least one of voltage, current, etc., and the switching state of the circuit breaker.

In addition, the sub-control unit 121 can also implement the conversion of the communication protocol to send the collected operating parameters to the monitoring platform 122, receive the control signal sent by the monitoring platform 122, and perform the corresponding connection to the power supply unit 111 based on the control signal. Switch control.

In some implementations, the monitoring center 122 can control the opening or closing of the sub-control unit 121. For example, in some application scenarios, when the power supply unit 111 correspondingly connected to one sub-control unit 121 is in the off state, the monitoring center 122 may turn off the sub-control unit 121.

In some alternatives, each sub-control unit 121 can include a control computer, and the control computer can include an acquisition module and a first central processing module. The collection module can be used to collect the operating parameters of the corresponding power supply unit 111.

In addition, the sub-control unit 121 may further include at least one second central processing module for controlling on-off of the circuit breaker of the corresponding power supply unit 111 based on the switching timing when the first central processing module fails.

By providing a redundant central processing module (for example, at least one second central processing module) in the sub-control unit 121, it is possible to prevent the sub-control unit 121 from functioning properly when the first central processing module fails, and the sub-control unit 121 is added.

In addition, the monitoring computer 1221 may further include at least one fourth central processing module for determining the switching timing of each circuit breaker based on the operating parameters collected by the respective sub-monitoring systems 121 when the third central processing module fails.

Similar to the function of the sub-control unit 121 providing a redundant central processing module, a redundant central processing module (for example, at least one fourth central processing module) is provided in the monitoring computer 1221 to prevent the third central processing module from malfunctioning. The monitoring computer 1221 is not working properly, increasing the reliability of the monitoring computer 1221.

In some implementations, an expert database can be stored in the monitoring computer 1221, and control logic can be stored in the expert database. For example, the control logic can be written by the programmable controller for performing switching timing control on each power supply unit according to the collected operating parameters of the power supply units.

For example, in some application scenarios, when one of the medium voltage power distribution modules 220 is de-energized, half of the medium voltage bus bars of the medium voltage power distribution module 220 and the low voltage bus bars of the low voltage power distribution module 230 are de-energized. The monitoring computer 1221 can make a decision based on the control logic stored in the expert database to determine the current operation, such as the low voltage bus couple in the medium voltage bus coupler and the low voltage power distribution module 230 in the medium voltage distribution module 220, Or start the generator set and so on.

In other application scenarios, for example, in the case where the data center power monitoring system has a low load rate, a certain number of power distribution modules such as UPS and HVDC can be turned off based on the control logic stored in the expert database to improve the operating efficiency of the system. To achieve collaborative management and dynamic tuning of data centers.
