摘要:隨著國民經(jīng)濟(jì)的快速發(fā)展，工業(yè)對電力的需要也越來越迫切，對電能的要求也更高。所以與用戶相關(guān)的供電系統(tǒng)非常重要。本設(shè)計(jì)根據(jù)某工廠的相關(guān)資料和實(shí)際情況，對該工廠的高壓配電所供電系統(tǒng)進(jìn)行設(shè)計(jì)。本設(shè)計(jì)主要是對工廠供配電系統(tǒng)的電氣部分進(jìn)行設(shè)計(jì)。 本設(shè)計(jì)首先根據(jù)工廠的資料對工廠的負(fù)荷進(jìn)行計(jì)算，然后根據(jù)需要進(jìn)行無功補(bǔ)償。根據(jù)負(fù)荷的實(shí)際情況確定主變壓器的臺(tái)數(shù)和容量，從而確定主接線方案，再進(jìn)行短路電流計(jì)算，以此為基礎(chǔ)選擇配電所的電氣設(shè)備，之后再進(jìn)行繼電保護(hù)的整定與防雷與接地等。本設(shè)計(jì)選擇在該廠設(shè)立總降壓變電所先將電壓降為廠區(qū)供電電壓6kV，再由各車間變電所降為負(fù)荷所需電壓。 本設(shè)計(jì)可以滿足工廠供電安全、可靠、優(yōu)質(zhì)、經(jīng)濟(jì)的特點(diǎn)，并保證各車間電氣設(shè)備的穩(wěn)定運(yùn)行，投資少，實(shí)用性高。 關(guān)鍵詞：6kV；高壓配電所；電氣主接線；功率補(bǔ)償；繼電保護(hù)
ABSTRACT:With the rapid development of the national economy, need of industrial electricity is also more and more urgent, the energy requirements are also higher. So the power system associated with the user is very important. This design according to the related data of a certain factory and the actual situation, the high-voltage power distribution on the factory power supply system design. According to the design of the first load the data on factory factory were calculated, and then according to the need for wattless power compensation. Determination of main transformer number and capacity according to the actual conditions of load, so as to determine the main wiring scheme, then the short-circuit current calculation, as a basis for the selection of electrical equipment, and then the selection and setting of relay protection and lightning protection and grounding. This design choice in the factory set up the total step-down substation first voltage drop for the factory power supply voltage of 6kV, then reduced by the plant substation voltage needed for load. The design result can meet the characteristics of the power plant safety, reliable, high quality, economy, and ensure the stable operation of the plant electrical equipment, less investment, high practicality.
