【摘要】：直流電源系統(tǒng)是水電站中重要的電氣設(shè)備,其系統(tǒng)的穩(wěn)定性和可靠性直接關(guān)系到整個(gè)電站的安全運(yùn)行。結(jié)合國(guó)際項(xiàng)目巴基斯坦N-J水電站的廠房布置及機(jī)電設(shè)備的分布特點(diǎn),簡(jiǎn)單介紹了直流電源系統(tǒng)的配置原則以及系統(tǒng)接線方案等內(nèi)容;根據(jù)標(biāo)準(zhǔn)《IEEE Std 485固定應(yīng)用的鉛酸電池組尺寸確定的推薦實(shí)施規(guī)范》,重點(diǎn)介紹了直流電源系統(tǒng)設(shè)計(jì)中直流負(fù)荷統(tǒng)計(jì)、蓄電池?cái)?shù)量及容量選擇的計(jì)算等內(nèi)容。最后,結(jié)合長(zhǎng)江勘測(cè)規(guī)劃設(shè)計(jì)研究有限責(zé)任公司近年來所參與的相關(guān)項(xiàng)目,對(duì)國(guó)內(nèi)、外工程中的直流電源系統(tǒng)設(shè)計(jì)方式等方面的情況進(jìn)行了分析比較,比較結(jié)果可為供水電站直流電源系統(tǒng)的設(shè)計(jì)提供參考。
[Abstract]:DC power supply system is an important electrical equipment in hydropower station. The stability and reliability of the system is directly related to the safe operation of the whole power station. Combined with the layout of the workshop and the distribution characteristics of the electromechanical equipment of the international project N-J Hydropower Station in Pakistan, the configuration principle of the DC power supply system and the system wiring scheme are briefly introduced. According to the standard < recommended Code of practice for determining the size of Lead-acid batteries for IEEE Std485 fixed applications, this paper mainly introduces the DC load statistics in the design of DC power supply system, the calculation of battery quantity and capacity selection and so on. Finally, combined with the related projects of the Yangtze River Survey Planning and Design Co., Ltd., this paper analyzes and compares the design methods of the DC power supply system in domestic and foreign projects. The comparison results can provide reference for the design of DC power supply system of hydropower station.
