【摘要】：在全球能源緊張的情況下，隨著用戶對電能需求的持續(xù)增長和電力電網(wǎng)規(guī)模的擴(kuò)大，為提高供電效率及減少能源的浪費，實現(xiàn)對電能質(zhì)量的有效監(jiān)測和治理變得越來越重要。國外的監(jiān)測儀器技術(shù)先進(jìn)、精確度高，但價格偏高，不適合我國的國情。國內(nèi)的測量儀器，功能單一，，受環(huán)境和電力波動影響大，且存在不能快速、精確地捕捉電能信息的缺點。 本課題提出一種基于Zigbee技術(shù)并利用微處理器S3C2440A和三相電能專用芯片ATT7022B的嵌入式電能質(zhì)量監(jiān)測系統(tǒng)。利用高精度計量芯片ATT7022B進(jìn)行了前端電壓及電流、相角等電能質(zhì)量參數(shù)的采集，并運用微處理器S3C2440A構(gòu)建的核心控制板實現(xiàn)對數(shù)據(jù)采集的控制和輸出。最后利用Zigbee技術(shù)進(jìn)行無線組網(wǎng)實現(xiàn)信息的匯總和存儲。 本論文首先論述了電能質(zhì)量的定義和電能質(zhì)量問題產(chǎn)生的根源。分析了國內(nèi)外電能質(zhì)量監(jiān)測裝置的研究現(xiàn)狀，探討了電能質(zhì)量的標(biāo)準(zhǔn)和改善措施，并對電能質(zhì)量的分析給出了一些理論分析方法。根據(jù)用戶的需求，最后給出了電能質(zhì)量監(jiān)測系統(tǒng)的實現(xiàn)方案。硬件設(shè)計方面包括前端模擬數(shù)據(jù)采集板和數(shù)字控制板的設(shè)計。前端信號采集板以ATT7022B為核心構(gòu)建包括：電源模塊、信號取樣模塊、校表模塊、通信模塊等；數(shù)字控制板以S3C2440A為核心構(gòu)建，主要由S3C2440A電路、存儲器電路、SPI通信接口電路、串口電路、網(wǎng)口電路等組成。無線網(wǎng)絡(luò)通信采用順舟科技的SZ02實現(xiàn)。軟件以嵌入式linux系統(tǒng)為核心，修改配置和編寫了linux嵌入式操作系統(tǒng)下的相關(guān)接口驅(qū)動程序。主要完成了前端參數(shù)采集、存儲和控制軟件，并完成SPI通信接口驅(qū)動程序的編寫。最后完成系統(tǒng)的整體硬件調(diào)試和軟件調(diào)試，系統(tǒng)運行穩(wěn)定，達(dá)到了設(shè)計要求。
[Abstract]:Under the circumstance of global energy shortage, it is more and more important to effectively monitor and control the power quality in order to improve the power supply efficiency and reduce the energy waste, along with the continuous increase of users' demand for electric energy and the expansion of power grid scale. Foreign monitoring instruments have advanced technology, high accuracy, but high price, which is not suitable for the national conditions of our country. The domestic measuring instrument has a single function and is greatly influenced by environment and power fluctuation, and it can not capture the electric energy information quickly and accurately. In this paper, an embedded power quality monitoring system based on Zigbee technology and using microprocessor S3C2440A and three-phase power chip ATT7022B is proposed. The power quality parameters such as front-end voltage, current and phase angle are collected by using high-precision metering chip ATT7022B, and the control and output of data acquisition is realized by using the core control board constructed by microprocessor S3C2440A. Finally, Zigbee technology is used to realize the collection and storage of information in wireless networking. This paper first discusses the definition of power quality and the root causes of power quality problems. This paper analyzes the research status of power quality monitoring devices at home and abroad, discusses the standards and improvement measures of power quality, and gives some theoretical analysis methods for the analysis of power quality. According to the demand of users, the realization scheme of power quality monitoring system is given at last. Hardware design includes front-end analog data acquisition board and digital control board design. The front-end signal acquisition board is composed of power module, signal sampling module, calibration table module, communication module and so on based on ATT7022B. The digital control board is composed of S3C2440A circuit, memory circuit, SPI communication interface circuit, serial port circuit, network port circuit and so on. The digital control board is constructed with S3C2440A as the core. Wireless network communication is realized by SZ02. The software takes the embedded linux system as the core, modifies the configuration and compiles the related interface driver under the linux embedded operating system. Mainly completed the front-end parameter acquisition, storage and control software, and completed the SPI communication interface driver program. Finally, the whole hardware debugging and software debugging are completed. The system runs stably and meets the design requirements.
