Description
Technical Field
The invention relates to the technical field of power supply, in particular to a dual-power monitoring system and method and a dual-power supply system.
Background
With the development of the big data era, data centers are increasingly important in social development, and the power supply safety level of a data machine room is higher and higher. The national standard (GB 50174-2008) A-level machine room or the international standard TIA-942Tier3 and above are designed to be connected with a two-way different mains supply (2N system power supply, general power supply voltage level 10KV) system for power supply. The data computer room is additionally provided with a self-contained power supply (such as a diesel generator set) so as to be connected with power supply. However, the power supply reliability of the utility power system is affected by uncontrollable natural conditions such as external natural disasters and equipment failures, so that sudden power failure occurs.
The design requirement of the data computer room is that when one path of the commercial power system is powered off, the commercial power system is automatically switched to another path of the power supply system through the interconnection switch to supply power. When the two power supply systems are powered off, the diesel generator set can be started by a self-contained power supply such as the diesel generator set, and the diesel generator set can supply power quickly. In order to ensure the running safety of the city power supply system, when the two power supply systems are powered off, the supplied network needs to be switched to the diesel generator side in a manual operation mode, so that the normal power supply of the supplied network is recovered through the diesel generator, and the diesel generator set is prevented from transmitting power backwards to the city power supply system.
For the situation that two power supply systems exist, when the two power supply systems stop supplying power, the equipment switch in the supplied network corresponding to the power supply system which is powered off later is in a closed state, part of the equipment switch in the supplied network corresponding to the power supply system which is powered off first is in an open state, and the equipment switch is generally set to have the function of automatic switching but not automatic recovery. Generally, operation and maintenance personnel cannot accurately determine the power failure sequence of the two power supply systems, so that when the two powered networks are restored to be powered on, the powered networks in a connected state (namely, the powered networks corresponding to the one powered system which is powered off later) cannot be restored to be powered on timely due to the fact that the powered networks corresponding to the power supply systems which are powered off first are restored preferentially, and therefore the efficiency of restoring the power to be powered on of the powered networks is low.
In view of the above, there is a need for an improved dual power supply system in the prior art to solve the above problems.

Because the first switch and the second switch are respectively provided with the closed indicating signs for representing that the switches are in the closed state, when the two paths of power supply systems stop supplying power, the first switch corresponding to the first path of power supply system which is powered off firstly can not display the closed indicating signs to users because the first switch is in the open state, and then the second switch corresponding to the second path of power supply system which is powered off displays the closed indicating signs to users because the second switch is still in the closed state. Therefore, after the two power supply systems stop supplying power, a user can accurately and quickly determine the power failure sequence of the two power supply systems based on whether the first switch or the second switch displays the closing indication mark, and therefore the power supply recovery efficiency of the important one power supply network is improved.

Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that functional, methodological, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
It will be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," "positive," "negative," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing and simplifying the description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered as limiting the present disclosure.
Generally, when one municipal power supply system is powered off and automatically switched to another municipal power supply system, or when two municipal power supply systems are powered off and manually switched to the diesel generator side for power supply, in the process of automatic switching or manual switching of a switch, core equipment of a data room is uninterruptedly supported by an Uninterruptible Power Supply (UPS), and if the diesel generator is not started quickly or the municipal power supply system is recovered to supply power to a supplied network, all power supply systems in the data room are interrupted, so that the normal operation of a service is influenced.
When the operation and maintenance personnel electrify the pre-recovered supplied network under the condition that the power failure sequence of the two power supply systems is not determined, the supplied network corresponding to the power supply system with the power failure firstly may be recovered preferentially (namely, the supplied network corresponding to the power supply system with the power failure firstly is communicated with the diesel generator set preferentially, and the supplied network cannot recover the power immediately when the power supply to the supplied network is recovered due to the fact that a part of equipment switches in the supplied network are in a switching-off state), and the supplied network corresponding to the important one-path power supply system (namely, the supplied network corresponding to the power supply system with the power failure later is recovered immediately when the power supply to the supplied network is recovered due to the fact that the equipment switches are in a switching-on state) is not recovered preferentially. Therefore, since the supplied network corresponding to the power supply system that is restored preferentially cannot be immediately energized, it is necessary to manually close the device switch in the supplied network corresponding to the power supply system that has been powered off first and that is restored preferentially successfully, which results in a significant reduction in the efficiency of restoring the energization of the supplied network due to the delay in the manual switching time. Moreover, when the supplied network is large, the manual power restoration method further reduces the power restoration efficiency due to insufficient agility of the response, and even interrupts all power supply systems in the data room due to untimely power supply of the supplied network.
In order to solve the above technical problem, so as to ensure normal operation of a data room and improve guarantee capability of power supply of the data room, as shown in fig. 1, an embodiment of the present invention provides a dual power supply monitoring system 100. The dual power supply monitoring system 100 includes: the dual-power automatic converter 10 is provided with two switches, namely a first switch 11 (i.e. one of the switches) and a second switch 12 (i.e. the other of the switches), in the dual-power automatic converter 10, the first switch 11 is connected to a first power supply system 21 of the two power supply systems, and the second switch 12 is connected to a second power supply system 22 of the two power supply systems. The dual-power automatic converter 10 is configured to control the first switch 11 to be switched on to control the first path power supply system 21 to supply power, and to automatically control the first switch 11 to be switched off when the first path power supply system 21 stops supplying power and control the second switch 12 to be switched on to control the second path power supply system 22 to supply power, so as to determine that the first path power supply system 21 is prior to the second path power supply system 22 to stop supplying power based on the closed indication flag 122 of the second switch 12 when the second path power supply system 22 stops supplying power. A closing indication mark 112 for indicating that the first switch 11 is in a closing state when the first switch 11 is closed is formed on the first switch 11, and a closing indication mark 122 for indicating that the second switch 12 is in a closing state when the second switch 12 is closed is formed on the second switch 12.
Of course, the first switch 11 may further have an off indication mark 111 for indicating to the user that the first switch 11 is in the open state when the first switch 11 is open, and the second switch 12 may further have an off indication mark 122 for indicating to the user that the second switch 12 is in the open state when the second switch 12 is open.
The close indicator 112 and the close indicator 122 may each be a red indicator, and the open indicator 111 and the open indicator 112 may each be a green indicator. The closing indication marks (the closing indication marks 112 and 122), and the opening indication marks (the opening indication marks 111 and 112) may be other marks capable of clearly distinguishing whether the first switch or the second switch is in the open state or the closed state, and are not limited to the scope defined by the embodiment of the present invention. For example, the close indication mark may be a text mark such as "close" or "on" to indicate that the corresponding first switch or second switch is in the closing state (or the operating state), and the open indication mark may be a text mark such as "open" or "off" to indicate that the corresponding first switch or second switch is in the opening state (or the closing state).
It should be noted that, when the first switch 11 or the second switch 12 is turned on, it means that the first switch 11 or the second switch 12 is communicated with the corresponding first power supply system or the second power supply system, that is, the corresponding first power supply system or the second power supply system supplies power to the supplied power network. It should be noted that only one of the first switch 11 and the second switch 12 can be in the closed state, that is, both switches cannot be in the closed state at the same time, otherwise, a short circuit occurs.
The dual-power monitoring system 100 of the embodiment of the invention respectively controls two paths of power supply systems to supply power through the first switch 11 and the second switch 12 configured in the dual-power automatic converter 10, controls the first path of power supply system 21 to supply power when the first switch 11 is switched on, and controls the first switch 11 to be switched off and the second switch 12 to be switched on when the first path of power supply system 21 stops supplying power so as to control the second path of power supply system 22 to supply power. Because the first switch 11 and the second switch 12 are both provided with the closing indication signs for indicating that the switches are in the closing state, when both the two power supply systems stop supplying power, the first switch 11 corresponding to the first power supply system which is powered off first does not display the closing indication sign 112 to the user because the first switch is in the opening state, and the second switch 12 corresponding to the second power supply system 22 which is powered off then displays the closing indication sign 122 to the user because the second switch is still in the closing state. Therefore, after the two-way power supply system stops supplying power, the user can accurately and quickly determine the power failure sequence of the two-way power supply system based on whether the closing indication mark is displayed on the first switch 11 or the second switch 12. The user preferentially recovers the powered network corresponding to the power supply system which has been powered off after the power failure according to the determined power failure sequence of the two power supply systems (namely preferentially leads the powered network corresponding to the power supply system which has been powered off after the power failure to be communicated with the diesel generator set), thereby directly recovering the normal power of the important powered network in place. Therefore, the efficiency of recovering the power supply of an important path by the power supply network is effectively improved, and the influence on the normal operation of the service due to the interruption of all power supply systems in the data machine room caused by the untimely power supply of the power supply network is prevented.
In the above embodiment, the dual power supply monitoring system according to the embodiment of the present invention further includes: and the alarm 31 and/or the warning lamp 32 are connected with the double-power-supply automatic converter 10, so that when the two power supply systems stop supplying power, warning is carried out through the alarm 31, and/or warning is carried out through the warning lamp 32. Therefore, when the two power supply systems stop supplying power, the alarm 31 and/or the warning lamp 32 warn the user to prompt the user to recover the power supply of the important power supply network in time, so that the power failure time of the power supply network is shortened. The user may be alerted in other manners (e.g., remote calling, etc.), and the scope of the present invention is not limited thereto.
It is to be noted that the two-line power supply system according to the embodiment of the present invention may be a two-line commercial power supply system.
With reference to fig. 1 and fig. 2, an embodiment of the present invention further provides a dual power supply monitoring method, which includes:
and 202, controlling a first switch 11 in the dual-power automatic converter 10 to be switched on so as to control a first path of power supply system 21 connected with the first switch 11 to supply power.
And 204, when the first power supply system 21 stops supplying power, controlling the first switch 11 to be switched off and controlling the second switch 12 to be switched on to control the second power supply system 22 to supply power.
And step 206, when the second road power supply system 22 stops supplying power, determining that the first road power supply system 21 stops supplying power in preference to the second road power supply system 22 based on the closing indication mark of the second switch 12.
A closing indication mark 112 for indicating that the first switch is in a closing state when the first switch is closed is formed on the first switch 11, and a closing indication mark 122 for indicating that the second switch is in a closing state when the second switch is closed is formed on the second switch 12. The first switch 11 is further formed with an off indication mark 111 for indicating to a user that the first switch is in an open state when the first switch is open, and the second switch 12 is further formed with an off indication mark 122 for indicating that the second switch is in an open state when the second switch is open.
According to the dual-power monitoring method, the first switch 11 in the dual-power automatic converter 10 is controlled to be switched on to control the first power supply system 21 connected with the first switch 11 to supply power, and then when the first power supply system 21 stops supplying power, the first switch 11 is controlled to be switched off and the second switch 12 is controlled to be switched on to control the second power supply system 22 to supply power. Because the first switch 11 and the second switch 12 are both provided with the closing indication signs for indicating that the switches are in the closing state, when both the two power supply systems stop supplying power, the first switch 11 corresponding to the first power supply system which is powered off first does not display the closing indication sign 112 to the user because the first switch is in the opening state, and the second switch 12 corresponding to the second power supply system 22 which is powered off then displays the closing indication sign 122 to the user because the second switch is still in the closing state. Therefore, after the two-way power supply system stops supplying power, the user can accurately and quickly determine the power failure sequence of the two-way power supply system based on whether the closing indication mark is displayed on the first switch 11 or the second switch 12. The user preferentially recovers the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure according to the determined power failure sequence of the two power supply systems (namely preferentially enabling the supplied network corresponding to the power supply system with the power failure after the power failure to be communicated with the diesel generator set), so that the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure can be directly recovered, and the normal electrification of the important supplied network can be further recovered in place. Therefore, the efficiency of recovering the electrification of the important path of the supplied network is effectively improved, and the influence on the normal operation of the service due to the interruption of all power supply systems in the data machine room caused by the untimely electrification of the supplied network is prevented.
In the foregoing embodiment, as shown in fig. 3, the dual power supply monitoring method according to the embodiment of the present invention further includes:
and 208, when the first power supply system and the second power supply system stop supplying power, controlling an alarm connected with the dual-power automatic transfer switch to warn a user.
As shown in fig. 4, the dual power supply monitoring method according to the embodiment of the present invention further includes:
and step 210, when the first power supply system and the second power supply system stop supplying power, controlling a warning lamp connected with the dual-power automatic transfer switch to warn a user.
It should be understood that when the two power supply systems stop supplying power, the alarm 31 and/or the warning lamp 32 can warn the user, so that the user can be prompted to recover the power supply of the important power supply network in time, and the power failure time of the power supply network is shortened. The user may be alerted in other manners (e.g., remote calling, etc.), and the scope of the present invention is not limited thereto.
It should be noted that the dual power monitoring method according to the embodiment of the present invention is applied to the dual power monitoring system according to any one of the embodiments, and a part of the same scheme as that of the dual power monitoring system in the dual power monitoring method may refer to the dual power monitoring system according to any one of the embodiments, and details are not described herein.
The embodiment of the present invention further provides a dual power supply system 200, which includes: a first power supply system 21; a second power supply system 22; in the dual power supply monitoring system 100 of any of the above embodiments, the dual power supply monitoring system 100 is connected to the first power supply system 21 and the second power supply system 22.
In the embodiment of the present invention, a part of the scheme of the dual power supply system 200 that is the same as the dual power supply monitoring system can refer to the dual power supply monitoring system 100 described in any of the above embodiments, and details are not described herein.
The dual-power supply system 200 of the embodiment of the invention controls two paths of power supply systems to supply power respectively through the first switch 11 and the second switch 12 configured in the dual-power automatic converter 10, controls the first path of power supply system 21 to supply power when the first switch 11 is switched on, and controls the first switch 11 to be switched off and the second switch 12 to be switched on when the first path of power supply system 21 stops supplying power so as to control the second path of power supply system 22 to supply power. Because the first switch 11 and the second switch 12 are both provided with the closing indication signs for indicating that the switches are in the closing state, when both the two power supply systems stop supplying power, the first switch 11 corresponding to the first power supply system which is powered off first does not display the closing indication sign 112 to the user because the first switch is in the opening state, and the second switch 12 corresponding to the second power supply system 22 which is powered off then displays the closing indication sign 122 to the user because the second switch is still in the closing state. Therefore, after the two-way power supply system stops supplying power, the user can accurately and quickly determine the power failure sequence of the two-way power supply system based on whether the closing indication mark is displayed on the first switch 11 or the second switch 12. The user preferentially recovers the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure according to the determined power failure sequence of the two power supply systems (namely preferentially enabling the supplied network corresponding to the power supply system with the power failure after the power failure to be communicated with the diesel generator set), so that the electrification of the supplied network corresponding to the power supply system with the power failure after the power failure can be directly recovered, and the normal electrification of the important supplied network can be further recovered in place. Therefore, the efficiency of recovering the power supply of an important path by the power supply network can be effectively improved, and the influence on the normal operation of the service due to the interruption of all power supply systems in the data machine room caused by the untimely power supply of the power supply network is prevented.
