Power Supply and Distribution System
ABSTRACT: The basic function of the electric power system is to transport the electric power towards customers. The l0kV electric distribution net is a key point that connects the power supply with the electricity using on the industry, business and daily-life. For the electric power, allcostumers expect to pay the lowest price for the highest reliability, but don't consider that it's self-contradictory in the co-existence of economy and reliable.To improve the reliability of the power supply network, we must increase the investment cost of the network construction But, if the cost that improve the reliability of the network construction, but the investment on this kind of construction would be worthless if the reducing loss is on the power-off is less than the increasing investment on improving the reliability .Thus we find out a balance point to make the most economic,between the investment and the loss by calculating the investment on power net and the loss brought from power-off.
供配電系統(tǒng)
摘要:電力系統(tǒng)的基本功能是向用戶輸送電能。lOkV配電網(wǎng)是連接供電電源與工業(yè)、商業(yè)及生活用電的樞紐,其網(wǎng)絡(luò)龐大及復(fù)雜。對于所有用戶都期望以最低的價(jià)格買到具有高度可靠性的電能。然而,經(jīng)濟(jì)性與可靠性這兩個(gè)因素是互相矛盾的。要提高供電網(wǎng)絡(luò)的可靠性就必須增加網(wǎng)絡(luò)建設(shè)投資成本。但是,如果提高可靠性使用戶停電損失的降低小于用于提高可靠性所增加的投資,那么這種建設(shè)投資就沒有價(jià)值了。通過計(jì)算電網(wǎng)的投資和用戶停電的損失,最終可找到一個(gè)平衡點(diǎn),使投資和損失的綜合經(jīng)濟(jì)性最優(yōu)。
關(guān)鍵詞:供配電,供電可靠性,無功補(bǔ)償,負(fù)荷分配
