【摘要】:通過對(duì)具體的電力系統(tǒng)進(jìn)行分析計(jì)算,我們可以了解到其各個(gè)配置是如何起到保護(hù)系統(tǒng)的作用,由此可以得到一個(gè)定值,在這個(gè)定值以內(nèi)工作即可達(dá)到保護(hù)裝置的系統(tǒng)運(yùn)行要求,這就叫做繼電保護(hù)的整定計(jì)算。整定計(jì)算在繼電保護(hù)工作中起到十分重要的作用。通過精細(xì)的整定計(jì)算,系統(tǒng)中的每個(gè)保護(hù)裝置才能在一起安全地進(jìn)行工作。 本文根據(jù)所要設(shè)計(jì)的110kV變電站的電力負(fù)荷資料,按照有關(guān)規(guī)定和規(guī)范,對(duì)110kV變電站進(jìn)行繼電保護(hù)的配置和整定計(jì)算,包括主接線設(shè)計(jì)和繼電保護(hù)的配置,短路電流計(jì)算以及繼電保護(hù)裝置的選型等。設(shè)計(jì)中首先根據(jù)變電站的資料,通過進(jìn)行技術(shù)比較和經(jīng)濟(jì)比較對(duì)變壓器進(jìn)行選型,進(jìn)而確定110kV電氣主接線圖,其次分別在最大運(yùn)行方式下和最小運(yùn)行方式下進(jìn)行了短路電流計(jì)算,對(duì)變壓器和線路也分別進(jìn)行繼電保護(hù)配置設(shè)計(jì)。
[Abstract]:Through the analysis and calculation of the specific power system, we can understand how each configuration plays the role of protecting the system, and thus we can get a certain value. The system operation requirement of the protective device can be achieved by working within this fixed value, which is called the setting calculation of the relay protection. Setting calculation plays an important role in relay protection. Each protection device in the system can work safely together by careful setting calculation. According to the power load data of the 110kV substation to be designed, the configuration and setting calculation of the relay protection for the 110kV substation are carried out according to the relevant regulations and specifications, including the main wiring design and the configuration of the relay protection. Short-circuit current calculation and relay protection device selection and so on. In the design, according to the data of substation, the transformer is selected by technical comparison and economic comparison, and then the main wiring diagram of 110kV is determined. Secondly, the short-circuit current is calculated under the maximum operation mode and the minimum operation mode, and the relay protection configuration is designed for the transformer and the line respectively.
