【摘要】：能源緊張,促進(jìn)可再生清潔能源產(chǎn)業(yè)的迅猛發(fā)展,太陽(yáng)能就是其中之一,把太陽(yáng)能轉(zhuǎn)換為電能再傳輸?shù)娇蛻舳耸褂?光伏變壓器應(yīng)運(yùn)而生。光伏發(fā)電利用太陽(yáng)能為發(fā)電能源,為此需要將光伏發(fā)電場(chǎng)建在日照時(shí)間長(zhǎng)、日光照射強(qiáng)烈的西北地區(qū),這些地區(qū)的環(huán)境都比較惡劣,遠(yuǎn)離市區(qū),因此無(wú)人值班智能化的光伏變電站應(yīng)運(yùn)而生且快速發(fā)展。如何為用戶提供合理化方案,如何快捷有效的合理的使用太陽(yáng)能以及如何減少故障實(shí)現(xiàn)遠(yuǎn)程計(jì)算機(jī)操作控制,這就需要對(duì)光伏箱式變電站進(jìn)行智能規(guī)化設(shè)計(jì)。依據(jù)智能變電站的發(fā)展趨勢(shì)和光伏發(fā)電的特點(diǎn),本文根據(jù)用戶智能化的實(shí)際需求設(shè)計(jì)光伏發(fā)電專用智能箱式變電站。在統(tǒng)一的自動(dòng)化平臺(tái)上,建立起對(duì)箱式變電站各個(gè)分立系統(tǒng)及元件的綜合管理、控制、保護(hù)、測(cè)量,實(shí)現(xiàn)在站控層可以了解箱式變電站的運(yùn)行狀況,電流、電壓、負(fù)荷率等參數(shù)。本文根據(jù)光伏箱式變電站的結(jié)構(gòu)特點(diǎn)將變電站劃分高壓側(cè)、低壓側(cè)、變壓器三個(gè)部分,“目”字形排列,配置相應(yīng)在線狀態(tài)檢測(cè)設(shè)備,從而實(shí)現(xiàn)對(duì)間隔內(nèi)元器件、保護(hù)裝置、儀表、測(cè)控裝置等設(shè)備進(jìn)行優(yōu)化,在保證供電質(zhì)量和供電可靠性的情況下實(shí)現(xiàn)智能化,進(jìn)一步提高光伏箱式變電站性價(jià)比。
[Abstract]:Energy shortage, promote the rapid development of renewable clean energy industry, solar energy is one of them, the conversion of solar energy to electricity and then transferred to the client for use. Photovoltaic transformers came into being. Photovoltaic generation uses solar energy to generate energy, so it is necessary to build photovoltaic fields in the northwest of China where the sun is long and the sunlight is strong. The environment in these areas is relatively bad. Far away from the urban area, the unattended and intelligent photovoltaic substation came into being and developed rapidly. How to provide the rational scheme for users. How to use solar energy efficiently and reasonably and how to reduce the fault to realize the remote computer operation control. This requires the intelligent planning design of photovoltaic box substation, according to the development trend of intelligent substation and the characteristics of photovoltaic power generation. This paper designs the special intelligent box substation for photovoltaic power generation according to the actual needs of users. On the unified automation platform, the integrated management and control of each discrete system and components of the box substation are established. Protection, measurement and realization in the station control layer can understand the operation status, current, voltage, load rate and other parameters of the box substation. According to the structural characteristics of photovoltaic box substation, the substation can be divided into high-voltage side and low-voltage side. The three parts of the transformer are arranged in the shape of "mesh", and the corresponding on-line state detection equipment is configured to optimize the equipment such as interspaced components, protective devices, instruments, measurement and control devices and so on. Under the condition of ensuring the quality and reliability of power supply, the performance and price ratio of photovoltaic box substation is further improved.
