摘要
UPS(Uninterruptible Power System)不间断电源设置的目的是确保在发生市电故障时向计算机设备提供电源保护。随着社会和科技的进步,对电源系统提出了新的要求:当市电停止超过一定时间而用户没有及时处理,UPS蓄电池耗尽后会出现强行关机的结果。这种情况与直接停电没有多少区别,甚至于系统所遭受到的伤害往往比单纯关闭系统更严重。如果这种情况发生在IDC或服务器或军事单位电脑,危害更大。为此,需要具有一定智能和网络管理功能的智能网络UPS电源做供电系统。要求它能够在电池能量即将耗尽而用户又不能及时关机的情况下保存相关数据,并按照程序设计实现自动关机,还能以远程管理方式通知网络管理员,为有效的管理计算机设备及其电源提供极大的便利。
智能网络UPS电源系统作为向重要场合的关键负载提供不间断电源的电力电子设备,其发展前景十分广阔。为了得到性能优良且工程实用性高的电源系统,本文致力于智能网络式UPS的研究,包括单机控制和双机并联运行技术的研究。
本文从智能网络UPS的基本概念入手,介绍了它的发展历史、发展趋势,并详细介绍了其工作原理和结构。在讨论了其硬件构造的基础上,进行了智能网络化UPS的软件控制问题的研究和大功率热并机技术以及远程控制技术的研讨。在计算机仿真平台MATLAB工具中,利用软件模拟了逆变结构和运行的结果,达到了设计的目的。
Uninterruptible Power System was also called UPS.When UPS set up, thegoal is to ensure providing the computer power protection equipment in caseof electricity failure. As society and the advancement of technology for powersystem sets new requirements: When the electricity stopped more than acertain time and users are not handled in a timely manner, UPS batterydepletion will happen after the forced shutdown results. This direct and nottoo different from the blackout, and even system suffered harm than simplyclosed system more serious. If in IDC or the server computer or militaryunits, greater hazards will happens. Therefore, we need to use an intelligentnetwork management and intelligent network functions in UPS power supplysystem. When battery energy exhausted, users have timely shutdown of thedata stored, and in accordance with procedures designed for automaticshutdown, but also to notify the remote management network administrators,for the effective management of computer equipment and its power to providegreat convenience.
As the key to provide uninterrupted power supply load of power electronicequipment, Intelligent Network UPS system to the important occasions itsvery broad prospects for development. In order to obtain higher quality andhigher utility project's power supply system, the intelligent network iscommitted to the UPS study including single and parallel operation controltechnology.
Based Intelligent Network UPS basic concept, introduced its history,development trends, and detailed information on its structure and workingprinciple. In discussing its hardware configuration on the basis of theIntelligent Network UPS control software research and high-power thermaland computer technology and remote control technology research review.Computer simulation platform in MATLAB tools, and use the software tosimulate the structure and operation of inverter results meet the designobjectives.
