【摘要】：隨著智能電網(wǎng)的不斷發(fā)展,國家對(duì)電能生產(chǎn)和輸配的可靠性、安全性、經(jīng)濟(jì)性提出了更高的要求。配電網(wǎng)位于輸電系統(tǒng)的終端,下接電力用戶,是制約電力系統(tǒng)整體性能的重要環(huán)節(jié)。其中,10kV配電網(wǎng)由于線路長、覆蓋廣、設(shè)備數(shù)量龐大、環(huán)境因素多樣等問題,智能化相對(duì)薄弱,其自動(dòng)化建設(shè)無疑將成為智能電網(wǎng)發(fā)展進(jìn)程中的關(guān)鍵所在。本文從實(shí)際應(yīng)用角度出發(fā),結(jié)合功能需求與行業(yè)標(biāo)準(zhǔn),研究并設(shè)計(jì)了一種基于ARM內(nèi)核的多功能分段開關(guān)控制器。本文首先分析了分段開關(guān)的工作原理,設(shè)計(jì)了過流保護(hù)、電流速斷、零序保護(hù)的動(dòng)作依據(jù)與流程,并根據(jù)零序功率方向判定設(shè)計(jì)了故障分段定位算法,然后分析比較各種交流采樣算法的優(yōu)劣,并對(duì)DFT算法進(jìn)行優(yōu)化,最后,根據(jù)配電網(wǎng)自動(dòng)化的發(fā)展需求,對(duì)智能控制器的功能進(jìn)行了分析與總結(jié)。在此基礎(chǔ)上,采用模塊化設(shè)計(jì)方法,完成了基于LPC1778芯片的主控模塊、基于ADE7878芯片的采樣模塊、基于SIM800C芯片的GPRS模塊、基于ZNE-100TL的以太網(wǎng)接口模塊、基于CC2530芯片的ZigBee模塊以及電源模塊、時(shí)鐘模塊、開入開出模塊等系統(tǒng)硬件電路的設(shè)計(jì)。在硬件設(shè)計(jì)基礎(chǔ)上,編寫了各個(gè)模塊的軟件驅(qū)動(dòng)程序,并設(shè)計(jì)了系統(tǒng)上層功能及流程。最后,對(duì)系統(tǒng)軟硬件進(jìn)行調(diào)試。實(shí)驗(yàn)結(jié)果表明,本控制器交流采樣誤差控制在±0.5%以內(nèi),可在50ms內(nèi)動(dòng)作切除故障線路,具備可靠的繼電保護(hù)功能,且具備"三遙"功能及友好的人機(jī)交互功能,系統(tǒng)運(yùn)行穩(wěn)定,滿足設(shè)計(jì)需求。
[Abstract]:With the continuous development of the smart grid, the state has put forward higher requirements for the reliability, security and economy of electric energy production and distribution. The distribution network is located in the terminal of the transmission system, and the power users are connected to the power system. It is an important link to restrict the overall performance of the power system. Among them, the 10kV distribution network is covered by a large number of equipment because of the long line, the large number of equipment and the environment. The problem of various factors, such as factors and so on, is relatively weak in intelligence, and its automation construction will undoubtedly become the key to the development of smart grid. From the perspective of practical application, this paper studies and designs a multi-function piecewise switch controller based on the ARM kernel, combining functional requirements and industry standards. This paper first analyzes the piecewise switch. Working principle, the operation basis and process of over current protection, current speed breaking, zero sequence protection are designed, and the fault segmentation algorithm is designed according to the zero sequence power direction decision. Then, the advantages and disadvantages of various AC sampling algorithms are analyzed and compared, and the DFT algorithm is optimized. Finally, according to the development demand of distribution network automation, the intelligent controller is applied to the intelligent controller. On this basis, using modular design method, the main control module based on LPC1778 chip, sampling module based on ADE7878 chip, GPRS module based on SIM800C chip, Ethernet interface module based on ZNE-100TL, ZigBee module based on CC2530 chip, power module, clock module, and clock module are opened. On the basis of hardware design, the software driver of each module is written on the basis of hardware design, and the upper function and process of the system are designed. Finally, the software and hardware of the system are debugged. The experimental results show that the control of the AC sampling error of this controller is less than 0.5%, and the fault line can be excised in 50ms. The road has reliable relay protection function, and has the function of "three remotely" and friendly man-machine interaction. The system runs stably and meets the design requirements.
