Delta逆变技术用于照明系统的研究
|
摘要
随着现代科学技术的发展,不同电力设备的使用使电力负荷变得越来越复杂,这直接导致了供电系统中电能质量问题日趋严重,电网电压存在如电压升高、跌落、波动、谐波、瞬变等各种干扰。这些问题会对许多敏感的设备产生不利影响,因此,电力用户对电能质量提出了更高的要求。
照明系统是电能质量问题的一个典型的受害对象系统。首先,电网电压的不稳定会造成光源的照明质量问题;其次,市电电网电压相对高于照明器具最佳工作电压,也会在灯具上产生多余的能耗。鉴于世界照明用电占总用电量的十分之一以上,节能潜力巨大,这在能源短缺的今天尤其显得严重。
针对上述问题,本课题研究的新拓扑的UDVR系统,是应照明系统对降压调节的要求而发展起来的一种电能质量补偿装置。本文从工程应用的角度出发,对传统的UDVR系统、新型拓扑结构的照明用UDVR系统及其基础性技术的Delta逆变技术进行了相关研究。
论文结构和主要研究内容如下:
首先,简单介绍立题的意义国内外技术背景与发展趋势,阐述了电能质量问题和电能质量补偿技术的发展现状和热点以及Delta逆变技术的发展和用于照明系统的意义。
其次,阐述Delta逆变技术的定义特点和用于照明系统的节能原理。其主电路结构、控制方法等相关技术内容也将详细叙述,并介绍了电网信号变量增量的三种检测方法。
接着,文章对基于Delta逆变技术的UDVR系统作了详细的研究,包括电路结构、工作原理和系统参数设定等,并针对一个具体的单相UDVR系统及其控制策略进行了设计和仿真。
本文的重点是对新型电路拓扑结构的照明节电系统的研究,并对其进行了优化控制算法。通过仿真论证结构的可行性,完成硬件和软件的设计,并在样机上完成了实验,系统可以安全、稳定、可靠地运行。
论文的最后部分对全文的工作进行总结与展望。
With the development of modern science and technology, there are more types of electrical consumer and the electrical load becomes much more complicated. It directly caused the deterioration of the Power Quality in Grid. These disturbances not only have negative impact on sensitive devices, but also bring much energy losses, which is regarded as unacceptable in nowadays.
Lighting System is a kind of typical victim system of power quality problems. For one thing, the unsteadiness of voltage may cause the light pollution. For another thing, the lamps may consume superfluous energy due to an overvoltage. Since the lighting systems in the world consume about 10% of the total electrical energy, we could find a huge space for energy saving in those systems.
Uninterruptible Dynamic Voltage Restorer (UDVR) is a good method to resolve those power quality problems mentioned above. It could compensate the grid voltage and provide the loads a pure, standard sine voltage wave. An Intelligent Energy Saver (IES) for lighting system with a novel converter circuit topology is a special UDVR system, which is developed due to the requirement of reducing input voltage in lighting system. This dissertation conducts an extensive and deep research on UDVR system, IES for Lighting System and the Delta Inverter technology, which is thought of the fundamental and key technology of a UDVR system.
First of all, the background of the project is described. The power quality problems and the development of power quality control technology are discussed in detail in the following section. The development of Delta Inverter and the meaning of using it in Lighting System is also reviewed.
Secondly, the definition, characteristic, main circuit, control methods, related technologies of Delta Inverter and principle of saving energy are discussed. Three methods of signal detection are also introduced.
Then in the third chapter, it gives a specific introduction of UDVR, including main circuit, system parameter and its principle, based on which an implementation of the UDVR system with specially designed control strategy is proposed and simulated.
Based on the research of UDVR in chapter three, an IES for Lighting System with a novel six switches AC-DC-AC circuit is presented in chapter four. This chapter also proposes a control algorithm for the new circuit topology and conducts a simulation and an experiment of the whole system.
The paper is summarized at the end of the dissertation.
