摘  要

　　　隨著電力電子技術(shù)的發(fā)展在分布式能源研究等領(lǐng)域的廣泛應(yīng)用，逆變器的設(shè)計(jì)、應(yīng)用和監(jiān)控的方式也在不斷研究中更新?lián)Q代。電源系統(tǒng)應(yīng)用領(lǐng)域?qū)╇娤到y(tǒng)的要求也越來越高，大功率容量、高可靠性、模塊化等逐漸成為各領(lǐng)域?qū)╇娤到y(tǒng)性能的新要求，傳統(tǒng)的集中式供電方式已經(jīng)不能滿足這些要求。多個(gè)電源模塊并聯(lián)實(shí)現(xiàn)擴(kuò)容可大大提高系統(tǒng)的靈活性，使電源系統(tǒng)的體積重量大為降低，各個(gè)模塊處于均流運(yùn)行時(shí)，其主開關(guān)器件的電流應(yīng)力也可大大減少，從根本上提高可靠性、降低成本。伴隨著上述問題的出現(xiàn)，并聯(lián)逆變電源通信監(jiān)控技術(shù)的研究也在不斷精進(jìn)，成為交流電源系統(tǒng)從傳統(tǒng)的集中式供電向分布式供電乃至智能電源系統(tǒng)供電模式發(fā)展過程中必須解決的課題。
　　　本課題研究的基于RS232總線的并聯(lián)逆變電源通信監(jiān)控系統(tǒng)，利用TI公司的TMS320FL2812的32位定點(diǎn)DSP的SCI通信模塊，通過RS232總線從各并聯(lián)模塊獲取并解析現(xiàn)場(chǎng)控制數(shù)據(jù)，響應(yīng)現(xiàn)場(chǎng)強(qiáng)實(shí)時(shí)性操作，實(shí)現(xiàn)對(duì)模塊工作的調(diào)度監(jiān)控，具有結(jié)構(gòu)簡潔、擴(kuò)容方便及可靠性高的優(yōu)點(diǎn)。上位機(jī)界面基于Visual C++集成開發(fā)環(huán)境，MFC（Microsoft Foundation Classes）是Microsoft公司定制的應(yīng)用程序包裝接口，極大的方便了設(shè)計(jì)人員對(duì)用戶界面的設(shè)計(jì)以及對(duì)數(shù)據(jù)庫的訪問[1]。
　　　本文介紹的內(nèi)容主要包括一下幾個(gè)部分：基于串口RS-232的硬件特性介紹以及電路設(shè)計(jì)；基于DSP2812開發(fā)板設(shè)計(jì)串口通信SCI軟件程序設(shè)計(jì)；基于VC++的上位機(jī)人際交互界面程序的設(shè)計(jì)；最后，課題中設(shè)計(jì)了監(jiān)控系統(tǒng)的可靠性、實(shí)時(shí)性驗(yàn)證分析，論證軟硬件設(shè)計(jì)的實(shí)用性。

The Research Of The Monitor Of The Parallel-inverter System
ABSTRACT
　　　For the increasing of the promotion and expansion of the power system applications, the requirements of the power supply system is also getting higher and higher. The high-power capacity, high reliability, modular becoming the new requirements of the various fields on the performance of the power supply system, the traditional centralized power supply the way has been unable to meet these requirements. Multiple power modules in parallel expansion can greatly improve the flexibility of the system, reduced the size of the weight of the power supply system. Each module in the current run, the main switching device current stress can be greatly reduced, and fundamentally improve the reliable and reduce costs.
　　　The parallel inverter communication monitoring technology is one of the issues that must be addressed to the distributed power supply in AC power system and even intelligent power supply system model development process from the traditional centralized power. Of this research project is based on RS232 bus parallel inverter communication monitoring system, using TI's TMS320LF2812 of 32-bit fixed-point DSP the SCI communication module via RS232 bus from parallel modules to obtain and parse site control data in response to field strong real-time operation, to achieve the control and supervision of the module work, has a simple structure, easy expansion and high reliability.
　　　Described in this article includes several parts: hardware features as well as circuit design based on serial RS-232; SCI serial communication software design based on DSP2812 Development Board; VC++ PC-based design of human interface program. Finally, this subjects analysis on reliability and real-time validation in the design of the monitoring system, demonstrate practicality of the software and hardware design.
