JMS是用于和面向消息的中間件相互通信的應(yīng)用程序接口。它既支持點(diǎn)對點(diǎn)(point-to-point)的域,又支持發(fā)布/訂閱(publish/subscribe)類型的域,并且提供對下列類型的支持:經(jīng)認(rèn)可的消息傳遞,事務(wù)型消息的傳遞,一致性消息和具有持久性的訂閱者支持。JMS還提供了另一種方式來對您的應(yīng)用與舊的后臺系統(tǒng)相集成。

This book is about multipoint cooperative communication, a key technology to overcome the long-standing problem of limited transmission rate caused by inter- point interference. However, the multipoint cooperative communication is not an isolated technology. Instead, it covers a vast range of research areas such as the multiple-input multiple-outputsystem, the relay network, channel state information issues, inter-point radio resource management operations, coordinated or joint transmissions, etc. We suppose that any attempt trying to thoroughly analyze the multipoint cooperative communication technology might end up working on a cyclopedia for modern communication systems and easily get lost in discussing all kinds of cooperative communication schemes as well as the associated models and their variations.

逆變器作為光伏陣列和電網(wǎng)接口的主要設(shè)備,它的性能決定著整個光伏發(fā)電系統(tǒng)的性能。為了將光伏陣列產(chǎn)生的電能最大限度地饋入電網(wǎng),并提高其運(yùn)行的穩(wěn)定度、可靠性和精確度,必須對并網(wǎng)逆變器的主電路拓?fù)溥x擇、濾波器參數(shù)設(shè)計(jì)及其控制策略選取等進(jìn)行深入研究。 論文首先分析了光伏發(fā)電的國內(nèi)外發(fā)展現(xiàn)狀和應(yīng)用前景,對光伏并網(wǎng)發(fā)電系統(tǒng)的種類、結(jié)構(gòu)和并網(wǎng)標(biāo)準(zhǔn)進(jìn)行了綜述。針對眾多適用于光伏并網(wǎng)的逆變器拓?fù)溥M(jìn)行了詳細(xì)的比較分析,最終確定了一臺單相滿載功率1kW、并網(wǎng)電壓220V的逆變器拓?fù)浼捌渲麟娐穮?shù),對其輸出濾波器參數(shù)進(jìn)行設(shè)計(jì),并對其進(jìn)行了幅頻特性分析。 其次,詳細(xì)分析和研究逆變器的并網(wǎng)控制策略,確定了在獨(dú)立工作模式下的瞬時電壓控制策略和在并網(wǎng)工作模式下的瞬時電流控制策略。根據(jù)選定的控制策略分別對其控制系統(tǒng)進(jìn)行了建模和閉環(huán)參數(shù)設(shè)計(jì),并利用Sabet軟件進(jìn)行系統(tǒng)仿真,驗(yàn)證了系統(tǒng)建模和設(shè)計(jì)的正確性。 接著,在分析光伏陣列特性的基礎(chǔ)上,總結(jié)和比較了常用的幾種MPPT(Maximum Power Point Tracking)控制方法,通過擾動觀測法對并網(wǎng)逆變器輸出電流的控制,實(shí)現(xiàn)了光伏陣列的MPPT,并給出了設(shè)計(jì)方案和實(shí)驗(yàn)驗(yàn)證。 最后,根據(jù)以上分析結(jié)果,研制了一臺基于DSP控制的光伏并網(wǎng)逆變器的試驗(yàn)樣機(jī),并詳述了其軟硬件的設(shè)計(jì)方案,給出了相關(guān)實(shí)驗(yàn)結(jié)果。

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to allow two-point calibration of gain and offset in precision data-acquisition systems.
