Abstract: |
Based on the analysis of new rural load characteristics, according to the State Grid Corporation of China’s new rural electrification standard and the features of new rural typical power supply modes, this paper proposes a practical method for determining the optimized allocation of sectionalizing switches in new rural medium-voltage(MV) distribution system. According to the reliability requirements of new rural power supply system, two types of network structure-the radial network mode and the hand-in-hand ring network mode are considered in this paper. Meanwhile, the load distribution state is also considered. The proposed method establishes an analytical model for determining the optimized number and locations of sectionalizing switches based on the state of new rural distribution system and selects two typical supply areas to calculate and then gives a reference conclusion which can be applied directly to the actual system. Compared with the intelligent algorithms mentioned in other literatures, this approach is more intuitive and simple, and therefore more practical.
