【正文】 ang Zhuang, improve their work style, service to the masses of the people, the foundation of consolidating grassroots, promote transformation across efforts, to further implement the central eight regulations and The opposition party and government austerity waste regulations , double section provincial regulations, municipal provisions of the twelve plan and the implementation measures for on improving the work style of close ties with the masses law, highlight style building, carry out the whole wind spirit, resolutely oppose formalism, bureaucracy, hedonism and wasteful extravagance to solve the problems, Party members and cadres of the style and the masses of people strong, the Ministry of Party members and cadres to further improve their thinking and understanding, to further change the style of the wind, the masses to close, honest and pragmatic people honest image to further establish the foundation to further reinforce the basic level. Style of the building of the new results to promote the construction of a powerful force of the county and the ecological culture of the county and county educational practice activities of the unit is mainly: the county and below county departments under the organs, enterprises and institutions directly under the township, street, and munity, village, nonpublic economic organizations, social organizations and other grassroots organizations. Agencies and branches, each single unit, follow the rules on internal institutions. Educational practice with step by adhere to the county leadership, leadership and leading cadres to focus on outstanding catch to directly contact the service of the masses of law supervision departments and window units, service industry, educational practice, pay attention to grasp the heavy towns, streets and villages, munity education activities and the masses of grassroots groups in close contact to strengthen, and the majority of Party members, cadres and the mass line line Marx doctrine view of the masses and the party39。參考資料 電力電子技術(shù) 電工技術(shù)學(xué)報等期刊雜志三相電壓型整流器的LCL濾波器分析與設(shè)計 電力電子新能源并網(wǎng)發(fā)電的控制研究 電力系統(tǒng)保護(hù)與控制DCDC逆變技術(shù)及其應(yīng)用 陳道煉 機(jī)械工業(yè)出版社周 次1～3周4～8周9～10周11～14周15～18周應(yīng)完成的內(nèi)容查閱相關(guān)的中文資料，熟悉控制方法的工作原理，翻譯一篇英文資料主電路的確定，參數(shù)設(shè)計控制方案的確定，控制電路的設(shè)計系統(tǒng)仿真研究撰寫論文，答辯指導(dǎo)教師：王曉寰職稱：講師 2009年12月 30日系級教學(xué)單位審批： 年 月 日Opinions and suggestions on the party39。本科畢業(yè)設(shè)計（論文）單相逆變器并網(wǎng)技術(shù)研究***燕 山 大 學(xué)2010年 6 月本科畢業(yè)設(shè)計（論文）單相逆變器并網(wǎng)技術(shù)研究學(xué)院（系）： 電氣工程學(xué)院 專 業(yè)： 應(yīng)用電子 學(xué)生 姓名： 學(xué) 號： 060103030097 指導(dǎo) 教師： 答辯 日期： 2010625 燕山大學(xué)畢業(yè)設(shè)計（論文）任務(wù)書學(xué)院： 電氣工程學(xué)院 系級教學(xué)單位：電氣工程及其自動化 學(xué)號060103030097學(xué) 生姓 名專 業(yè)班 級應(yīng)電063題目題目名稱單相逆變器并網(wǎng)技術(shù)研究題目性質(zhì)：工程設(shè)計 （ ）；工程技術(shù)實驗研究型（ ）；理論研究型（√ ）；計算機(jī)軟件型（ ）；綜合型（ ）。s mass line educational practiceAccording to the central and provincial, municipal unified deployment, according to municipal Party mittee about carrying out the party39。s speak seriously as a basic attitude, adhere to positive education, to carry out criticism and self criticism group, adhere to the pragmatic, more emphasis on leadership, pay more attention to the layers of the demonstration, more focus on the four winds, solve the problem, pay more attention to open the door, the participation of the masses, pay more attention to the classification guidance.

The strategy integrates an outer loop grid current regulator with capacitor current regulation to stabilize the system. The current regulation is used for the outer grid current control loop. The frequency of switching is slower in the high power gridconnected inverter. Compared with tradition type L or type LC, output filter and output current’s THD of type LCL are all on this basis, the system uses the LCL filter. This paper pares the net current of the singlephase inverter and net single loop and double loop under two control strategies, and the case of sudden disturbance of the dynamic change of the system.In plete control system on the basis of theoretical analysis, design and production of this article is based on TMS320LF2407DSP’s digital control hardware test system, including the DSP external circuit, analog sampling and conditioning circuit, isolation, driver circuit, protection circuit and auxiliary power, etc., via MATLAB software to validate the feasibility of the theory. Achieve power factor is 1 and network requirements.Keywords Gridconnected inverter。然而，通過增加能源消耗促進(jìn)經(jīng)濟(jì)發(fā)展的粗放增長方式已造成全球大氣、土壤、水源等諸多方面環(huán)境質(zhì)量的嚴(yán)重下降，暴露出以煤炭等常規(guī)能源為主的能源結(jié)構(gòu)的弊端?？稍偕茉粗饕ㄌ柲?、風(fēng)能、水能、生物質(zhì)能、地?zé)崮芎秃Ｑ竽艿?。因此，世界各國發(fā)展可再生能源所采取的戰(zhàn)略也有一定的差別。2005年8月的(2005年國家能源政策法)明確要求為太陽能、地?zé)?
