110KV線路繼電保護課程設(shè)計
[摘要]：為給110KV單電源環(huán)形電網(wǎng)進行繼電保護設(shè)計，首先選擇過電流保護，對電網(wǎng)進行短路電流計算，包括適中電流的正序、負(fù)序、零序電流的短路計算，整定電流保護的整定值。在過電流保護不滿足的情況下，相間故障選擇距離保護，接地故障選擇零序電流保護，同時對距離保護、零序電流保護進行整定計算，并用AUOCAD繪制出保護配置原理圖。
[關(guān)鍵詞]：繼電保護、短路電流、整定計算
[ 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.
