华为网络能源节能减排的三大措施
 在持续稳定地使用能源的过程中，先进功率电子技术的应用、提高设备的能效比、大规模使用太阳能发电等措施，可以推进节能减排，帮助全人类进入“绿色能源”时代。
石油等传统化石能源的产量呈现下降的趋势，伴随着日益增长的能源需求，**能源供应面临严峻的挑战。在开发新一代能源的同时，提高现有能源的使用效率，即节能，是一项重要的应对手段。而化石燃料的消耗迅速上升，还会带来一些问题，包括以二氧化碳为主的温室气体排放导致**气候变暖。这使得在节能的同时，减排也成为了全世界关注的问题。
2009年11月，***公布了我国的温室气体减排目标，即到2020年，单位国内生产总值的二氧化碳排放要比2005年下降40%－45%。因此，各行各业都应该担负起节能减排的社会责任。在持续稳定地使用能源的过程中，有哪些技术和措施可以推进节能减排，帮助全人类进入“绿色能源”时代？
措施一：电能技术革新
电能是使用较普遍的二次能源。在发达**中一半左右的一次能源，如煤、石油、天然气、铀矿等，会被用来发电，电气化率因此成为衡量**现代化程度的重要指标。典型的能源系统包括产生、传输、使用三个环节。电能在传输环节有*特的优势，能够以光速方便快捷地传输能量。出于对远距离输电和旋转动力的需求，三相交流**得到了普及应用。从大约一**前直到现在，几乎所有**都采用50Hz或60Hz的三相交流**输电。
为了达到节能减排的目的，传统电能技术需要进行革新。在发电环节，新能源技术的比例逐步增加，典型新能源发电装置的输出，是频率和电压均变化的交流电（风力发电）或电压变化的直流电（太阳能发电）；在用电环节，要求电机（用电量约占总发电量一半）的旋转速度随用户要求而改变，以节约电能；在输电环节，要求电网能够在保持频率稳定的同时，具有更好的稳定性和柔性，以提高电网利用率。
所有这一切，都需要能够在定频定压的三相交流电，以及变频（或直流）变压的能量源（或用电器）之间，实现高效互联的功率变换的装置。功率电子技术恰好满足了这一需求。

功率电子技术
功率电子技术是使用功率半导体技术对电能进行变换的技术。功率变换器是功率电子技术的具体载体，其通过现代控制技术，对功率半导体器件的导通和关断状态，进行动态控制，完成不同能量形式之间的转换。功率电子技术在革新传统电能技术，促进节能减排方面的作用体现在能源系统的三个环节。
在发电环节，新能源发电是节能减排的重要方向。预计到2020年，我国风电装机约为1.5亿千瓦，太阳能装机为2000万千瓦。新能源发电具有发电电压和频率均与现有电力系统不匹配的特征，因此需要功率变换器作为连接电网的接口，以实现能量的可靠输送，即并网。
目前用于风能、太阳能的功率变换器功率可达MW量级，且必须具有电网故障穿越的能力，以保证在电网暂态电压跌落时，仍能与电网连接，并支撑电网电压。
在用电环节，功率电子技术用于电机控制，可以起到节能作用。我国“十一五”规划目标要求降低电机用电量2%，即年均节电200亿度，相当于节约两个三峡水电站的年发电量。为了达成节电目标，电机负载主要为风机水泵类型，采用功率电子技术平均节电约20%。
在输电环节，以柔性交流输电技术、静止无功补偿技术、基于SCR的高压直流输电技术和基于IGBT的轻型直流输电技术为代表的功率电子技术，是智能电网的重要核心技术。在输出能量波动较大的风能、太阳能发电装置大规模引入电网后，上述基于电力系统应用的功率变换器，可以通过控制电网的潮流分布和提高电网稳定裕度，达到提高电网传输效率，节能减排的目的。
除此以外，功率电子技术在新能源汽车、机车牵引、储能等诸多促进节能减排的领域，也起到了重要作用。
功率半导体器件
功率半导体器件是功率电子技术的核心。从1958年美国通用电气公司研制出世界上**个工业用普通晶闸管开始，电能的变换和控制从旋转的变流机组和静止的离子变流器，进入由功率半导体器件构成的变流器时代。
功率半导体器件是发电、输电、变配电、用电、储能的核心部件，用于电能分配、电能转换、电能控制，起到改善电力、控制电能、节能环保的作用。它对电能的控制，类似于水龙头对水流的调节和控制，可对电流、电压、功率、频率，进行精确高效的控制和变换。
功率电子装置（产品）的重要特征参数是效率。功率半导体器件作为能源输送的通道，其能效直接影响整机系统的整体效率。功率半导体器件依照设备的要求，变换电源的电压与频率等，同时将功率送到各个元器件中。从电子设备整体来看，功率半导体器件耗能越低，设备的能源利用率就越高。这使功率半导体成为节能减排的关键点。
在国际范围内，功率半导体器件的发展经历了三个阶段，包括以大功率二极管、晶闸管（Silicon Controlled Rectifier—SCR）作为代表的**代器件；20世纪70年代出现的称之为**代的自关断器件，如门较可关断晶闸管（Gate-Turn-Off Thyristor—GTO）、大功率双较型晶体管（Bipolar Junction Transistor—BJT或Giant Transistor—GTR）等；以及20世纪80年代出现的以绝缘栅较双较型晶体管（Insulated-gate Bipolar Transistor—IGBT或IGT）为代表的*三代复合导电机构的场控半导体器件。
值得指出的是，这三个阶段是交叉并行的，新一代器件的出现并不意味着老的器件被淘汰。**SCR产量仍占全部功率半导体器件总数的一半，是目前高压、大电流装置中**的元件。
20世纪80年代后期，功率半导体器件的发展趋势是模块化、集成化，即按照电力电子电路的各种拓扑结构，将多个相同的功率半导体器件或不同的功率半导体器件，封装在一个模块中。这样可缩小器件体积、降低成本、提高可靠性。IGBT的发展方向是高压、大电流，不断占去部分晶闸管的市场份额。
在SCR、GTO时代，我国的研制、生产能力与国际相当。遗憾的是，在国外开始IGBT产业化时，我国功率半导体产业的发展停滞了近30年。直到2006年11月，在汪梄生院士和多位技术**的呼吁下，以及**的支持下，情况才有了一些改变。以华为为代表的企业，正努力将通信领域的电子信息控制技术应用于电力（功率）电子产业，以实现能源的高效转换和利用，为ICT领域节能减排开辟出一条全新的道路。总体来说，我国正逐步整合构建独立自主的电力（功率）电子产业，向国际先进水平迈进。
措施二：提高设备能效比
未来的能源使用中，能源使用效率（能效）和碳排放的管理至关重要，是避免“炭”壁垒的基础。节约一度电比生产一度再生电力更重要。
在ICT领域，节能减排空间巨大。通常情况下，IT设备或通讯设备的耗电不到IDC机房或者BTS基站耗电的50%，即PUE值（总耗电与IT或CT设备耗电之比）大于2。
所以说节能减排需要综合的能效管理系统，精确地测量各用电部件的功耗，全天候的数据采集、监控、分析和综合管理。为了将PUE值降到1.2以下，智能、精准的综合能效管理需要围绕高能效去设计产品和E2E解决方案，如IDC中采用的对IT机房的综合管理、Row级精确温控及能效管理、Rack级的精确温控及能效管理等手段。
设备本身的节能减排，首先要降低IT、CT设备的功耗，采取智能调度、服务迁移、智能休眠等节能措施；其次要做到精确的能源供给，在**供电安全的前提下，适配电池、电源及UPS等；第三要通过能效管理系统的精确调度，做到精准的制冷和散热，综合利用空调、直通风、热交换等技术，**ICT设备的安全运行，以保证综合能效比**。

Three measures of energy conservation and emission reduction of huawei network energy.
Continued to steadily in the process of energy use, the application of advanced power electronic technology, improve equipment can effect comparing, large-scale use of solar power and other measures, can promote the energy conservation and emissions reduction, help mankind into the era of "green energy".
The decline in production of traditional fossil fuels, such as oil, presents a serious challenge to the global energy supply along with the growing demand for energy. While developing a new generation of energy, it is an important means to improve the efficiency of existing energy sources, namely energy conservation. And the rapid rise in fossil fuel consumption raises questions about global warming, including carbon dioxide - based greenhouse gas emissions. This makes it a problem for the whole world to reduce emissions while saving energy.
In November 2009, *** published the goal of reducing greenhouse gas emissions by 40% to 45% below 2005 levels by 2020. Therefore, all industries should be responsible for energy conservation and emission reduction. In the process of using energy continuously and steadily, what technologies and measures can promote energy conservation and emission reduction to help mankind enter the era of "green energy"?
Measure 1: electric power technology innovation.
Electricity is the most common secondary energy source. About half of the energy in developed **, such as coal, oil, gas and uranium, will be used to generate electricity, and the electrification rate will become an important indicator of the degree of modernization. Typical energy systems include generation, transmission and use. Electric energy has unique advantages in transmission, which can transmit energy easily and quickly at the speed of light. Due to the demand for long-distance transmission and rotary power, the three-phase communication has been widely used. From about a hundred years ago until now, almost all ** have been using the three-phase communication of 50Hz or 60Hz.
In order to achieve the goal of energy conservation and emission reduction, traditional power technology needs to be innovated. Link of power generation, the proportion of new energy technology is gradually increased, the output of the typical new energy power generation device, alternating current (ac) is the frequency and voltage are change (wind power) or direct current voltage change (solar power); In the process of electricity consumption, the rotation speed of the motor (about half of the total power generating capacity) is required to be changed with the user's requirements to save energy. In the transmission link, it is required that the power grid can maintain the stable frequency and have better stability and flexibility to improve the utilization rate of the power grid.
All this, you need to be able to in the fixed frequency constant pressure of three-phase alternating current, and frequency conversion variable pressure (or dc) power source (or use electrical appliances), between efficient interconnection of power transformation device. The power electronics technology just meets this need.
Huawei UPS5000-A-120K is good and cheap.
Power electronics
Power electronics technology is a technology that USES power semiconductor technology to transform electrical energy. Power converter is the concrete carrier of power electronic technology, through the modern control technology, the conduction of power semiconductor devices and turn off state, dynamic control, complete the transformation between different form of energy. Power electronics technology in the innovation of traditional power technology, the promotion of energy conservation and emission reduction is reflected in the energy system three links.
In the generation link, new energy generation is an important direction of energy conservation and emission reduction. It is estimated that by 2020, China will have about 150 million kilowatts of wind power and 20 gigawatts of solar power. New energy power generation has a power voltage and frequency with the existing power system does not match the characteristics, so need a power converter as connected to the grid interface, so as to realize the reliable transmission energy, namely grid.
Currently used in wind power, solar power inverter power of MW level, and must have the ability to power grid failure through, in order to make sure the power grid transient voltage drop, still can be connected to the grid, and support the grid voltage.
Power electronics is used for motor control, which can save energy. China's "11th five-year plan" aims to reduce the electricity consumption of the motor by 2 percent, i.e., the annual energy saving of 20 billion yuan, which is equivalent to saving the annual power generation of two three gorges hydropower station. In order to achieve the power saving target, the motor load is mainly the type of fan pump, and the average power saving of power electronic technology is about 20%.
In transmission link to flexible ac transmission technology, static reactive compensation technology, high-voltage direct current transmission technology based on SCR and light dc transmission technology based on the IGBT as a representative of the power electronic technology, is an important core technology of the smart grid. Volatile in the output energy of wind energy, solar power systems on a large scale power grid are introduced to the power converter based on power system application, can control the trend of the power grid distribution and improve power grid stability margin, to improve the efficiency of power transmission, the purpose of energy saving and emission reduction.
In addition, power electronics has played an important role in promoting energy conservation and emission reduction in new energy vehicles, locomotives and energy storage.
Power semiconductor devices.
Power semiconductor devices are the core of power electronics technology. From 1958, the United States ge company developed the world * * industrial ordinary thyristor, power transformation and control from the rotary converter unit and the stillness of the ion current transformer, into the era of composed of power semiconductor devices converter.
Power semiconductor devices is power generation, transmission, distribution and utilization, the core parts of the energy storage for power distribution, power conversion, power control, improve the power, control power, and the effect of energy conservation and environmental protection. Its control of electric energy is similar to the regulation and control of water flow by the faucet, which can control and transform the current, voltage, power and frequency accurately and efficiently.
The important characteristic parameter of power electronic device (product) is efficiency. As a channel for energy transport, power semiconductor devices directly affect the overall efficiency of the whole system. The power semiconductor devices, according to the requirements of the equipment, transform the voltage and frequency of the power supply, and send the power to the various components. As a whole, the lower the energy consumption of power semiconductor devices, the higher the energy efficiency of the equipment. This makes power semiconductor the key point of energy conservation and emission reduction.
In the international scope, the development of power semiconductor devices has gone through three stages, including the power diode, the Silicon Controlled Rectifier (SCR) as the representative of ** generation devices; In the 1970s, self-closing devices, such as Gate turn-off Thyristor (GTO), high-power Bipolar Transistor (BJT or Giant store-gtr), were introduced in the 1970s. As well as the field control semiconductor devices of the third generation of composite conducting institutions, which appeared in the 1980s with the Insulated gate Bipolar Transistor (IGBT or IGT).
It is worth pointing out that these three stages are cross-parallel, and the emergence of a new generation of devices does not mean that old devices are obsolete. Global SCR production still accounts for half of the total power semiconductor devices, and is an irreplaceable element in high voltage and large current devices.
In the late 1980 s, the development trend of power semiconductor devices is modularization, integration, namely according to the topological structure of power electronic circuit, will be more than the same power semiconductor devices or different power semiconductor devices, encapsulated in a module. This can reduce device volume, reduce cost and improve reliability. The development direction of IGBT is high voltage and high current, which continuously occupies the market share of some thyristors.
In the era of SCR and GTO, China's development and production capacity is equivalent to that of the international community. Unfortunately, the development of the power semiconductor industry in China has been stagnant for nearly 30 years. Until November 2006, born in wang 梄 academicians and several technical * * appeal, as well as the support of * *, just had some changes. Represented by huawei company, which is communication in the field of electronic control technology is applied in the power electronics industry (power), in order to realize efficient conversion and utilization of energy, energy conservation and emissions reduction in ICT field opens up a new path. In general, China is gradually integrating the construction of an independent electric power (power) electronics industry and moving forward to the international advanced level.
Measure 2: improve the efficiency ratio of equipment.
In future energy use, energy efficiency (energy efficiency) and management of carbon emissions are essential to avoid the basis of "carbon" barriers. Saving one kilowatt-hour is more important than producing one kilowatt-hour of electricity.
In the ICT sector, there is huge space for energy conservation and emission reduction. Typically, IT equipment or communication devices consume less than 50% of the power consumed by the IDC machine room or BTS base station, that is, the PUE value (the ratio of total power consumption to IT or CT equipment) is greater than 2.
Therefore, energy conservation and emission reduction requires a comprehensive energy efficiency management system, which accurately measures the power consumption of various power components, and provides round-the-clock data collection, monitoring, analysis and comprehensive management. To PUE value dropped below 1.2, intelligent and accurate comprehensive management need to go around the energy-efficient design of energy efficiency products and E2E solution, such as IDC adopt the integrated management of the IT room, Row level accurate temperature control and energy efficiency management, Rack level of precise temperature control and management of energy efficiency.
The energy saving and emission reduction of the equipment itself should firstly reduce the power consumption of IT and CT equipment, and adopt energy saving measures such as intelligent dispatching, service migration and intelligent dormancy. Secondly, it is necessary to provide accurate energy supply, which is suitable for battery, power supply, UPS and so on. The third through precise scheduling of energy efficiency management system, achieve precise cooling and heat dissipation, the comprehensive utilization technology, such as air conditioning, direct the wind, heat exchange guarantee safe operation of the ICT equipment, to ensure the comprehensive energy efficiency
