Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements 不间断电源系统(UPS)第3部分指定性能和测试要求的方法
发布日期: 2011-03-14
IEC 62040-3:20 11适用于提供单相或三相固定频率交流电的移动式、固定式和固定式电子不间断电源系统(UPS)。输出电压不超过1 000 V交流电。并且结合了能量存储系统,通常通过直流连接。链接。本标准旨在规定完整UPS的性能和测试要求,而不是单个UPS功能单元的性能和测试要求。各个UPS功能单元在参考书目中引用的IEC出版物中进行了处理,这些出版物到目前为止适用,与本标准并不矛盾。本标准涵盖的UPS的主要功能是确保交流电的连续性。电源。UPS还可以通过将电源保持在规定的特性内来提高电源的质量。UPS的功率范围很广,从不到一百瓦到几兆瓦,以满足各种负载对电力可用性和质量的要求。有关典型UPS配置和拓扑的信息,请参阅附录A和B。当电源开关构成UPS的组成部分并与其输出相关联时,本标准还涵盖了UPS测试和性能。包括断路器、旁路开关、隔离开关和系带开关。这些开关与UPS的其他功能单元相互作用,以保持负载电源的连续性。本标准不涵盖: -常规交流电。输入和输出配电板或直流。电路板及其相关开关(例如,用于电池、整流器输出或逆变器输入的开关); -IEC 62310涵盖的独立静态传输系统-3; -其中输出电压源自旋转机器的系统。 注1本标准承认信息技术(IT)设备的电力可用性是UPS的主要应用。因此,本标准中规定的UPS输出特性也旨在确保与IT设备的要求兼容。受制造商声明中所述的任何限制,这包括对稳态和瞬态电压变化的要求,以及对IT设备的线性和非线性负载特性的供应的要求。 注2本标准规定的试验载荷模拟线性和非线性载荷特性。规定其使用的目的是验证制造商声明的设计和性能,并最大限度地减少测试期间的复杂性和能耗。注3本标准针对50 Hz和60 Hz应用,但不排除IEC 60196范围内的其他频率应用。这取决于制造商和采购部门之间关于任何特定要求的协议。 注4本标准涵盖的单相和三相电压UPS包括但不限于单相、双线供电的UPS;单相、三线;两相、三线、三相、三线和三相、四线负载。 第二版取消并取代了1999年出版的第一版,构成了技术修订。重大技术变更为: -参考试验载荷-定义和应用修订(3.3.5和6.1.1.3); -测试时间表-按修订类型和常规测试分组的单个表格呈现(见6。1.6,表3); -动态输出电压性能特性-测量指南-添加(附录H); -UPS效率-要求和测量方法-添加(附件I和J); -功能可用性-UPS可靠性完整性等级分类指南-添加(附录K)。
IEC 62040-3:2011 applies to movable, stationary and fixed electronic uninterruptible power systems (UPS) that deliver single or three phase fixed frequency a.c. output voltage not exceeding 1 000 V a.c. and that incorporate an energy storage system, generally connected through a d.c. link. This standard is intended to specify performance and test requirements of a complete UPS and not of individual UPS functional units. The individual UPS functional units are dealt with in IEC publications referred to in the bibliography that apply so far that they are not in contradiction with this standard. The primary function of the UPS covered by this standard is to ensure continuity of an a.c. power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. UPS have been developed over a wide range of power, from less than hundred watts to several megawatts, to meet requirements for availability and quality of power to a variety of loads. Refer to Annexes A and B for information on typical UPS configurations and topologies. This standard also covers UPS test and performance when power switches form integral part of a UPS and are associated with its output. Included are interrupters, bypass switches, isolating switches, and tie switches. These switches interact with other functional units of the UPS to maintain continuity of load power. This standard does not cover:
- conventional a.c. input and output distribution boards or d.c. boards and their associated switches (e.g. switches for batteries, rectifier output or inverter input);
- stand-alone static transfer systems covered by IEC 62310-3;
- systems wherein the output voltage is derived from a rotating machine.
NOTE 1 This standard recognises that power availability to information technology (IT) equipment represents a major UPS application. The UPS output characteristics specified in this standard are therefore also aimed at ensuring compatibility with the requirements of IT equipment. This, subject any limitation stated in the manufacturer's declaration, includes requirements for steady state and transient voltage variation as well as for the supply of both linear and non-linear load characteristics of IT equipment.
NOTE 2 Test loads specified in this standard simulate both linear and non-linear load characteristics. Their use is prescribed with the objective of verifying design and performance, as declared by the manufacturer, and also of minimising any complexity and energy consumption during the tests.
NOTE 3 This standard is aimed at 50 Hz and 60 Hz applications but does not exclude other frequency applications within the domain of IEC 60196. This is subject to an agreement between manufacturer and purchase in respect to any particular requirements arising.
NOTE 4 Single phase and three-phase voltage UPS covered by this standard include without limitation UPS supplying single-phase, two-wire; single-phase, three-wire; two-phase, three-wire, three-phase, three-wire and three-phase, four-wire loads.
This second edition cancels and replaces first edition published in 1999 and constitutes a technical revision. The significant technical changes are:
- reference test load - definition and application revised (3.3.5 and 6.1.1.3);
- test schedule - presented as a single table grouped by revised type and routine tests (see 6.1.6, Table 3);
- dynamic output voltage performance characteristics - guidance to measure - addition (Annex H);
- UPS efficiency - requirements and methods of measure - addition (Annexes I and J);
- functional availability - guidance for UPS reliability integrity level classification - addition (Annex K).
