【摘要】 在世界能源日益短缺的背景下,世界各国都加大了对可再生能源的研究,风光互补发电系统作为一种稳定性和经济性都比较好的能源利用方式得到了越来越广泛的应用。评价风光互补发电系统主要部件的实际运行性能,判断风光互补发电系统是否达到设计要求,需要实时测试风光互补发电系统的各项参数。采用传统仪器进行测试,虽然准确度高,但效率低下。本文将虚拟仪器的概念应用于风光互补发电监测系统,完成了风光互补发电监测系统的硬件和软件的选择和设计。本文介绍了风光互补发电系统的工作原理,分析了组成风光互补发电系统各部分的特性,提出了风光互补发电监测系统包括硬件和软件的整体方案,并以风光互补发电路灯系统为例计算了系统各部分的容量。本文设计风光互补发电监测系统主要分为硬件和软件两个方面,硬件系统选择以阿尔泰公司的PCI-8735数据采集卡为核心,设计了监测方案,采用合适的传感器和设计了信号调理电路,将被测信号转化为数据采集卡可以识别的信号；软件系统开发了基于LabVIEW语言的监测软件平台。监测软件平台分为前面板和程序面板,本文设计了简洁、美观的前面板,编写了显示程序、转速和风速的测量程序、Access数据库存储程序、新建数据表程序和数据调用程序,实现了对风光互补发电系统各项参数的数据采集、处理、实时显示和存储调用的功能。另外本文还对LabVIEW的Datasocket功能和远程面板技术进行了应用分析。最后根据本文所设计的风光互补发电监测系统,在山东大学风能实验基地安装了一套风光互补发电路灯系统基础上,对所研制的风光互补发电监测系统进行了6个月的连续实验。结果表明,本文所研发的监测系统数据采集准确,显示系统正确易读,数据存储量足够大,达到了设计要求,对于指导纯风力发电、纯太阳能发电以及风光互补发电系统的设计和性能优化具有实际意义。更多还原

【Abstract】 Under the background of decrease of the energy in the world, the research of the renewable energy in every country is increasing and hybrid wind/photovoltaic power generation system which has good stability and economy is being more widely used. It is important to test the parameters of the hybrid wind/photovoltaic power generation system for evaluating the actual operating performance of the system and determine whether the system meet the design requirements. It is inefficient to use traditional instruments. The concept of virtual instrument is applied to the monitoring system and the design of the hardware and software of the monitoring system is completed in this paper.This paper introduces the basic principle of the wind/photovoltaic generation system and analysis the characters of each component which compose the generation system. The design plan which includes hardware and soft ware is proposed in this paper. Taking the hybrid wind/photovoltaic lamp system for an example, the capacity of the various parts of the system is calculated in this paper.The design of the monitoring system consists of two sections:the design of the hardware and the design of the software. This paper selects the appropriate sensors and monitoring plan based on the PCI-8735 data acquisition card of ART company and the measured signal can be changed into the signal which the data acquisition card can identify. This paper develops the software platform by LabVIEW language. The simple and elegant front panel is designed in this paper. The display program, wind turbine speed and wind speed measurement program, Access database storing program, new data table establishing program and data calling program are designed in this paper. The parameters of the system is collected, processed, displayed and stored real-time by the monitoring system. Besides, datasocket and remote panel technology of LabVIEW is introduced in this paper.Finally, according to the design of monitoring system in this paper the wind/photovoltaic lamp system is installed in SDU Wind Power Research Establishment. The monitoring system in this paper is installed in SDU Wind Power Research Establishment for experiment for 6 months. The results show that the monitoring system has the advantages of accurate data collection.easy to read and display and large data storage capacity, so the monitoring system can reach the requirements of the design. The design in this paper can be used for designing and the optimization of the wind power, solar power and hybrid wind/photovoltaic power.更多还原
