110KV線路繼電保護(hù)課程設(shè)計(jì)
[摘要]：為給110KV單電源環(huán)形電網(wǎng)進(jìn)行繼電保護(hù)設(shè)計(jì)，首先選擇過(guò)電流保護(hù)，對(duì)電網(wǎng)進(jìn)行短路電流計(jì)算，包括適中電流的正序、負(fù)序、零序電流的短路計(jì)算，整定電流保護(hù)的整定值。在過(guò)電流保護(hù)不滿足的情況下，相間故障選擇距離保護(hù)，接地故障選擇零序電流保護(hù)，同時(shí)對(duì)距離保護(hù)、零序電流保護(hù)進(jìn)行整定計(jì)算，并用AUOCAD繪制出保護(hù)配置原理圖。
[關(guān)鍵詞]：繼電保護(hù)、短路電流、整定計(jì)算
[ summary]: In order to ring 110 KV single power grid to relay design, the first choice over-current protection, short-circuit current of the power network, including the positive sequence moderate current, negative sequence, zero-sequence of short-circuit current, the current protection of the entire tuning value. In the over-current protection are not satisfied with the circumstances, select a distance phase fault protection, choice of zero-sequence fault current protection At the same time, distance protection, and zero-sequence current protection to the entire set, and used to map out protection configuration AUOCAD schematic.
