【摘要】：隨著我國經(jīng)濟的持續(xù)飛速發(fā)展、工業(yè)用電和居民生活用電都呈現(xiàn)出快速增長的趨勢，每年國家都投入巨額資金用于新建發(fā)電廠和改造電網(wǎng)，但是仍然無法滿足日漸增長的用電需求，導(dǎo)致每年都會出現(xiàn)季節(jié)性的大范圍用電荒現(xiàn)象，而且愈演愈烈[1]。目前，受低碳經(jīng)濟、可持續(xù)發(fā)展及綠色節(jié)能等的影響，人們越來越追求社會經(jīng)濟發(fā)展與生態(tài)環(huán)境保護雙贏，那么建設(shè)更加安全、可靠、環(huán)保、經(jīng)濟的電力系統(tǒng)已經(jīng)勢在必行，智能電網(wǎng)應(yīng)運而生，而智能電表作為智能電網(wǎng)建設(shè)的重要基礎(chǔ)設(shè)備，其承擔(dān)著原始電能數(shù)據(jù)采集計量、實時監(jiān)測、自動控制、信息交互等任務(wù)。 目前國內(nèi)應(yīng)用的大部分電表都是普通的電子式電能表，只有采集原始電量參數(shù)、自動抄表等基本功能，應(yīng)用場合也比較單一，通常應(yīng)用于居民區(qū)，一戶一表制。無法滿足日益復(fù)雜的用電場合的需求，，如住宅用電、集體宿舍用電、商場、店面和辦公樓對于電表的功能要求都不一樣。而在技術(shù)解決方案中，傳統(tǒng)的單片機運行速度比較慢，片內(nèi)資源比較小，不適用于多功能、高精度、高速實時處理信息的場合。而高速的DSP芯片需要的擴展外設(shè)比較多，系統(tǒng)比較復(fù)雜，開發(fā)成本相對比較高，不適用于智能電表開發(fā)。本項目采用的STM32系列ARM芯片具有較高的性價比，外設(shè)豐富、可以實現(xiàn)數(shù)據(jù)采集處理、人機交互、通訊接口等功能，ARM芯片配合專門電能計量芯片ATT7022E使得整個系統(tǒng)體積小、功耗低、穩(wěn)定性高，具有較高的實用價值。 通過對國內(nèi)外智能電表進行研究，分析目前國內(nèi)對智能電表的需求情況，我們認(rèn)為開發(fā)出一款多功能多用途的智能電表對于國家的智能電網(wǎng)建設(shè)是非常必要的。本文從實際應(yīng)用角度出發(fā)，設(shè)計并實現(xiàn)了一種能源管理型的單相/三相智能電表，電表的技術(shù)指標(biāo)、電氣性能、功能要求、適應(yīng)環(huán)境、抗干擾和可靠性等方面均按照國家電網(wǎng)公司的智能電表技術(shù)標(biāo)準(zhǔn)來設(shè)計。
[Abstract]:With the sustained and rapid development of our economy, industrial power consumption and household electricity consumption are both showing a rapid growth trend. Every year, the country spends a huge amount of money on building new power plants and reforming power grids. But still can not meet the growing demand for electricity, leading to a seasonal large-scale shortage of electricity every year, and intensified [1]. At present, under the influence of low-carbon economy, sustainable development and green energy conservation, people are increasingly pursuing a win-win situation between social and economic development and ecological environment protection. Therefore, it is imperative to build a more secure, reliable, environmentally friendly and economical power system. Smart grid emerges as the times require, and smart meter, as an important basic equipment of smart grid construction, undertakes the tasks of raw power data acquisition and measurement, real-time monitoring, automatic control, information exchange and so on. At present, most of the ammeters used in our country are ordinary electronic watt-hour meters. They only have the basic functions of collecting the original electric parameters and automatically reading the meter. The application situation is also relatively simple, usually used in residential areas, one household, one meter system. Unable to meet the needs of increasingly complex electricity situations, such as residential electricity, collective dormitory electricity, shopping malls, stores and office buildings have different functional requirements for electricity meters. However, in the technical solution, the traditional single-chip microcomputer is not suitable for multi-function, high-precision, high-speed and real-time information processing because of its slow running speed and small in-chip resources. The high speed DSP chip needs more extended peripherals, more complex system and higher development cost, so it is not suitable for intelligent ammeter development. The STM32 series arm chip adopted in this project has high performance-price ratio and rich peripherals. It can realize data acquisition and processing, man-machine interaction, communication interface and other functions such as arm chip with special electric energy metering chip ATT7022E, which makes the whole system small in volume and low in power consumption. It has high stability and high practical value. Through the research of intelligent ammeter at home and abroad and the analysis of domestic demand for intelligent ammeter at present, we think that it is very necessary to develop a multi-function and multi-purpose smart meter for the construction of smart grid in our country. In this paper, a single-phase / three-phase intelligent ammeter with energy management is designed and realized from the point of view of practical application. Anti-jamming and reliability are designed according to the smart meter technical standard of State Grid Company.
