【摘要】：能源緊張,促進可再生清潔能源產業(yè)的迅猛發(fā)展,太陽能就是其中之一,把太陽能轉換為電能再傳輸到客戶端使用,光伏變壓器應運而生。光伏發(fā)電利用太陽能為發(fā)電能源,為此需要將光伏發(fā)電場建在日照時間長、日光照射強烈的西北地區(qū),這些地區(qū)的環(huán)境都比較惡劣,遠離市區(qū),因此無人值班智能化的光伏變電站應運而生且快速發(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能以及如何減少故障實現遠程計算機操作控制,這就需要對光伏箱式變電站進行智能規(guī)化設計。依據智能變電站的發(fā)展趨勢和光伏發(fā)電的特點,本文根據用戶智能化的實際需求設計光伏發(fā)電專用智能箱式變電站。在統(tǒng)一的自動化平臺上,建立起對箱式變電站各個分立系統(tǒng)及元件的綜合管理、控制、保護、測量,實現在站控層可以了解箱式變電站的運行狀況,電流、電壓、負荷率等參數。本文根據光伏箱式變電站的結構特點將變電站劃分高壓側、低壓側、變壓器三個部分,“目”字形排列,配置相應在線狀態(tài)檢測設備,從而實現對間隔內元器件、保護裝置、儀表、測控裝置等設備進行優(yōu)化,在保證供電質量和供電可靠性的情況下實現智能化,進一步提高光伏箱式變電站性價比。
[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.
