摘要

偏远山区线路长、末端电压低、供电可靠性差，充分利用本地可再生能源，建设微电网是解决上述问题的有效途径。对广东连南电网及试点线路存在的问题进行具体分析，提出光储微电网升级改造方案，实践过程中进一步采用“三相不平衡治理”、“架空线故障精准定位”和“电力通道及设备智能巡检”等措施，并对试点方案进行投资估算及效果分析。研究结果表明，所提出的方案能回收建设投资，显著改善用户电能质量和供电可靠性，可解决分布式电源无序上网难题，具有推广应用价值。

Abstract

In view of the problems of long line, low terminal voltage and poor reliability in remote mountainous areas, an effective way is to make full use of local renewable energy and build microgrid. In this paper, the existing problems of Liannan power grid and pilot line are analyzed, and the reconstruction scheme of microgrid with photovoltaic and energy storage is proposed. In the process of practice, the ‘three-phase unbalance governance’，the ‘accurate fault location of overhead line’，and the ‘intelligent inspection of power channel and power equipment’，are further adopted to improve power supply quality. The investment estimation and effect analysis of the proposed scheme are carried out. The results show that the proposed scheme can significantly improve the power quality and supply reliability, and deal with the disordered access of distributed generation, which has the value of popularization and application.
