淮南电网电磁环网解环分析

Analysis of Electromagnetic Loop Network Solution in Huainan Power Grid

淮南500 k V主网架逐渐成型,500 k V和220 k V电网间高低压电磁环网已经形成。针对淮南电网特点,对淮南220 k V电磁环网进行了解环分析,提出了一套合理的解环方案,实现对淮南220 k V电网的分区运行,并考虑一个分区失去上级电源后另一分区作为备用电源这一典型场景下的供电可靠性。采用案例验证了解环方案的合理性。

Huainan 500 kV main grid has been gradually formed,and 500 k V and 220 k V power grid between the high and lowvoltage electromagnetic ring has been established. Aiming at the characteristics of Huainan Power Grid,the 220 k V electromagnetic ring network in Huainan is analyzed and a set of reasonable solution scheme is proposed to realize the zoning operation of Huainan 220 k V power grid and consider the power supply reliability under the typical scenario where one partition loses the power of the other and then acts as the backup power. The case verifies the rationality of the solution of the solution loop according to the principle of solution loop and provides a reference for the successful implementation of the electromagnetic solution loop in Huainan.
