Description

服务器集中供电电源控制方法、 系统及装置  Server centralized power supply control method, system and device
技术领域 本发明涉及一种电子设备制造领域， 特别涉及一种服务器集中供电电源控 制方法、 系统及装置。 背景技术 The present invention relates to the field of electronic device manufacturing, and in particular, to a server centralized power supply control method, system and device. Background technique
随着互联网服务功能的不断提升， 机房中服务器的数量也在急剧增加， 由 于为每个服务器独立供电的方案会导致资源的巨大浪费， 因此目前主要釆用集 中供电的方式为服务器供电。 然而目前的集中放电方式对所有电源调整模块进 行统一控制， 即同时开启或关闭， 并一直保持工作状态。  With the continuous improvement of Internet service functions, the number of servers in the equipment room has also increased dramatically. Since the solution for independently powering each server will lead to huge waste of resources, it is currently mainly used to provide power to the server by means of centralized power supply. However, the current centralized discharge mode controls all power adjustment modules in a unified manner, that is, simultaneously turned on or off, and remains in operation.
现有技术的缺点是， 由于电源调整模块的转换效能会随着服务器的负载的 变化而变化， 因此目前方案无法保证电源调整模块工作在高效能区域， 从而无 法达到高效能的效果。对于 N+N的双路供电方案， 电源的实际负载更是始终都 在 50%的额定负载以下， 电源调整模块的 AC转 DC的效能始终都处在较低的 水平， 因此能耗较高， 不利于节能。  The disadvantage of the prior art is that since the conversion performance of the power adjustment module varies with the load of the server, the current solution cannot ensure that the power adjustment module operates in a high-performance area, and thus the high-performance effect cannot be achieved. For the N+N dual-supply solution, the actual load of the power supply is always below 50% of the rated load, and the AC-to-DC performance of the power supply adjustment module is always at a low level, so the energy consumption is high. Not conducive to energy saving.

需要说明的是， 在本发明的实施例中输入既可以为交流输入， 也可为直流 输入。 如果为交流输入， 则电源调整模块为整流模块； 如果为直流输入， 则电 源调整模块为变压模块。  It should be noted that in the embodiment of the present invention, the input may be either an AC input or a DC input. If it is an AC input, the power adjustment module is a rectifier module; if it is a DC input, the power adjustment module is a transformer module.
电源控制器 300与供电电源 100的输出相连，且与供电电源 100中的 M*N 个电源调整模块均相连。 电源控制器 300用于获得供电电源 100的输出的当前 输出电流和当前输出电压， 并才艮据供电电源 100的输出的当前输出电流和当前 输出电压计算供电电源的实际功耗。在本发明的实施例中，由于多个服务器 400 的实际功耗负载难以确定， 因此选择供电电源 100的实际功耗负载作为多个服 务器 400的实际功耗负载。 在本发明的一个优选实施例中， 电源控制器 300可 通过 PM-Bus或 I2C总线监控供电电源 100的当前输出电流和当前输出电压。 具体地， 可通过公式 W=UI计算供电电源的实际功耗， 其中， W为当前实际功 耗， U为供电电源当前输出电压， I为供电电源当前输出电流。 The power controller 300 is connected to the output of the power supply 100 and is connected to the M*N power adjustment modules in the power supply 100. The power controller 300 is configured to obtain the current output current and the current output voltage of the output of the power supply 100, and calculate the actual power consumption of the power supply according to the current output current and the current output voltage of the output of the power supply 100. In the embodiment of the present invention, since the actual power consumption load of the plurality of servers 400 is difficult to determine, the actual power consumption load of the power supply 100 is selected as the actual power consumption load of the plurality of servers 400. In a preferred embodiment of the invention, the power controller 300 can monitor the current output current and current output voltage of the power supply 100 via a PM-Bus or I 2 C bus. Specifically, the actual power consumption of the power supply can be calculated by the formula W=UI, where W is the current actual power consumption, U is the current output voltage of the power supply, and I is the current output current of the power supply.
在本发明的实施例中， 电源控制器 300还用于获取供电电源 100的效率负 载曲线， 并根据效率负载曲线确定第一调整阔值和第二调整阔值， 其中， 第二 调整阔值大于第一调整阔值。 在该实施例中， 供电电源 100的效率负载曲线可 以预先存储在电源控制器 300之中。 在本发明的实施例中， 供电电源 100的效 率负载曲线通过实验获得， 如图 2所示， 为本发明一个实施例的供电电源的效 率负载曲线示意图。从图 2可以看出供电电源 100的转换效率是按区域分布的， 要保证较高的转换效率， 需要控制电源始终工作在相应的有效负载区域。 具体 地， 从图 2中可以看出， 有效负载区域约为 35%-55%, 在有效负载区域内供电 电源 100能够有较高的转换效率， 因此在本发明的实施例中， 将第一调整阔值 和第二调整阔值分别设为 35%和 55%。 在此， 需要说明的是， 在本发明的实施 例中对于不同的电源调整模块， 其对应的效率负载曲线可能会有所差别， 但原 理与上述描述相同， 因此在此不再赘述。 In the embodiment of the present invention, the power controller 300 is further configured to obtain an efficiency load curve of the power supply 100, and determine a first adjustment threshold and a second adjustment threshold according to the efficiency load curve, where the second adjustment threshold is greater than The first adjustment is wide. In this embodiment, the efficiency load curve of the power supply 100 can be stored in advance in the power controller 300. In the embodiment of the present invention, the power supply 100 is effective. The rate load curve is obtained through experiments, as shown in FIG. 2, which is a schematic diagram of the efficiency load curve of the power supply according to an embodiment of the present invention. It can be seen from Fig. 2 that the conversion efficiency of the power supply 100 is distributed by region. To ensure high conversion efficiency, it is necessary to control the power supply to always operate in the corresponding payload area. Specifically, as can be seen from FIG. 2, the payload area is about 35%-55%, and the power supply 100 can have a higher conversion efficiency in the payload area, so in the embodiment of the present invention, the first The adjustment threshold and the second adjustment threshold are set to 35% and 55%, respectively. It should be noted that, in the embodiment of the present invention, the corresponding efficiency load curves may be different for different power supply adjustment modules, but the principle is the same as the above description, and therefore will not be further described herein.
电源控制器 300根据供电电源 100的实际功耗、 电源调整模块当前开启个 数 i、 输入相数M、 及每个电源调整模块的额定功耗计算供电电源的当前效率。 具体地， 可通过公式 W= P( M*N*w)计算供电电源的当前效率， 其中， W为上 述计算的当前实际功耗， P为供电电源的当前效率， w为电源调整模块的额定 功耗。 如果供电电源 100的当前效率小于第一调整阔值或大于第二调整阔值， 则相应地增加或减少每一相输入对应的电源调整模块的开启数量。 在本发明的 一个实施例中， 4叚设第一调整阔值 P1约为 35%, 第一调整阔值 P2约为 55%。 如果 P小于 P1 ,则电源控制器 300相应地增加每一相输入对应的电源调整模块 的开启数量， 如果 P大于 P2, 则电源控制器 300相应地减少每一相输入对应的 电源调整模块的开启数量。  The power controller 300 calculates the current efficiency of the power supply according to the actual power consumption of the power supply 100, the current number of power supply adjustment modules i, the number of input phases M, and the rated power consumption of each power adjustment module. Specifically, the current efficiency of the power supply can be calculated by the formula W=P(M*N*w), where W is the current actual power consumption calculated above, P is the current efficiency of the power supply, and w is the rating of the power supply adjustment module.

If the current efficiency of the power supply 100 is less than the first adjustment threshold or greater than the second adjustment threshold, the number of power adjustment modules corresponding to each phase input is increased or decreased accordingly. In one embodiment of the invention, the first adjustment threshold P1 is about 35% and the first adjustment threshold P2 is about 55%. If P is less than P1, the power controller 300 correspondingly increases the number of power-on adjustment modules corresponding to each phase input. If P is greater than P2, the power controller 300 correspondingly reduces the power-on adjustment module corresponding to each phase input. Quantity.
如图 3所示， 为本发明实施例的服务器集中供电电源控制系统结构图。 该 服务器集中供电电源控制系统包括供电电源 100和电源控制器 300。 其中， 供 电电源 100包括 M相输入 110和 M*N个电源调整模块 120。 在该实施例中 , 每一相输入 110都与 N个电源调整模块 120相连， 且 M相输入的电源调整模 块的输出为供电电源 100的输出 130, 其中， M和 N为整数， 且 N大于 1。 电 源控制器 300与供电电源 100的输出 130相连，并与 M*N个电源调整模块 120 均相连。 在该实施例中， 电源控制器 300用于根据供电电源 100的输出的当前 输出电流和当前输出电压计算供电电源的实际功耗。具体地，可通过公式 W=UI 计算供电电源的实际功耗， 其中， W为当前实际功耗， U为供电电源当前输出 电压， I 为供电电源当前输出电流。 在本发明的一个优选实施例中， 电源控制 器 300可通过 PM-Bus或 I2C总线监控供电电源 100的当前输出电流和当前输 出电压。 As shown in FIG. 3, it is a structural diagram of a server centralized power supply control system according to an embodiment of the present invention. The server centralized power supply control system includes a power supply 100 and a power controller 300. The power supply 100 includes an M phase input 110 and M*N power adjustment modules 120. In this embodiment, each phase input 110 is connected to the N power adjustment modules 120, and the output of the power adjustment module of the M phase input is the output 130 of the power supply 100, where M and N are integers, and N is greater than 1. The power controller 300 is connected to the output 130 of the power supply 100 and is connected to the M*N power adjustment modules 120. In this embodiment, the power controller 300 is configured to calculate the actual power consumption of the power supply according to the current output current and the current output voltage of the output of the power supply 100. Specifically, the formula W=UI can be used. Calculate the actual power consumption of the power supply, where W is the current actual power consumption, U is the current output voltage of the power supply, and I is the current output current of the power supply. In a preferred embodiment of the invention, the power controller 300 can monitor the current output current and current output voltage of the power supply 100 via a PM-Bus or I 2 C bus.
电源控制器 300获取供电电源 100的效率负载曲线， 并才艮据效率负载曲线 确定第一调整阔值和第二调整阔值， 其中， 第二调整阔值大于第一调整阔值。 例如， 可以选择效率大于一定阔值（例如 94% ) 时对应的负载作为第一调整阔 值和第二调整阔值。 电源控制器 300根据供电电源 100的实际功耗、 电源调整 模块 120当前开启个数 i、 输入 110的相数 M、 及每个电源调整模块 120的额 定功耗计算供电电源 100的当前效率。 具体地， 可通过公式 W= P( M*N*w)计 算供电电源的当前效率， 其中， W为上述计算的当前实际功耗， P为供电电源 的当前效率， w为电源调整模块的额定功耗。 如果供电电源 100的当前效率小 于第一调整阔值或大于第二调整阔值， 则相应地增加或减少每一相输入对应的 电源调整模块的开启数量。 在本发明的一个实施例中， H没第一调整阔值 P1 约为 35%, 第一调整阔值 P2约为 55%。 如果 P小于 P1 , 则电源控制器 300相 应地增加每一相输入对应的电源调整模块 120的开启数量， 如果 P大于 P2, 则 电源控制器 300相应地减少每一相输入对应的电源调整模块 120的开启数量。 具体地，电源控制器 300可通过控制电源调整模块 120的 PS-ON信号或者控制 电源调整模块 120的开关电流实现对电源调整模块 120的开启或关闭控制。 本 发明实施例能够动态地调节系统中实际工作的电源调整模块 120的数量， 从而 保证供电电源 100的所有实际工作的电源调整模块 120的负载都在电源调整模 块 120有效负载范围， 因此能够将供电电源的效能最大化。  The power controller 300 obtains the efficiency load curve of the power supply 100, and determines the first adjustment threshold and the second adjustment threshold according to the efficiency load curve, wherein the second adjustment threshold is greater than the first adjustment threshold. For example, the corresponding load when the efficiency is greater than a certain threshold (for example, 94%) may be selected as the first adjustment threshold and the second adjustment threshold. The power controller 300 calculates the current efficiency of the power supply 100 based on the actual power consumption of the power supply 100, the current number of power-on modules 120, the number of phases M of the input 110, and the rated power consumption of each power adjustment module 120. Specifically, the current efficiency of the power supply can be calculated by the formula W=P(M*N*w), where W is the current actual power consumption calculated above, P is the current efficiency of the power supply, and w is the rating of the power supply adjustment module. Power consumption. If the current efficiency of the power supply 100 is less than the first adjustment threshold or greater than the second adjustment threshold, the number of power adjustment modules corresponding to each phase input is increased or decreased accordingly. In one embodiment of the invention, H has no first adjustment threshold P1 of about 35% and a first adjustment threshold P2 of about 55%. If P is less than P1, the power controller 300 increases the number of power-on adjustment modules 120 corresponding to each phase input. If P is greater than P2, the power controller 300 correspondingly reduces the power adjustment module 120 corresponding to each phase input. The number of open. Specifically, the power controller 300 can implement on/off control of the power conditioning module 120 by controlling the PS-ON signal of the power conditioning module 120 or by controlling the switching current of the power conditioning module 120. The embodiment of the present invention can dynamically adjust the number of power adjustment modules 120 actually working in the system, thereby ensuring that all the actually working power adjustment modules 120 of the power supply 100 are under the effective load range of the power adjustment module 120, and thus can supply power.
