Evaluation Method for Reliability Improvement Effect of Rural Distribution Network Planning Project

  Introduction  Quantitative evaluation for power supply reliability improvement effect of planning projects is guided by secondary indexes. In order to solve the problems that the planning of rural distribution network is lacks , this paper proposes a rapid evaluation method for reliability improvement effect of large-scale rural distribution network planning projects.

  Method  This paper first analyzed the main characteristics of rural distribution network. Then, based on the evaluation requirements of power supply reliability improvement effect of distribution network planning project and a simplified topology, this paper proposed an evaluation method for power supply reliability improvement effect of rural distribution network planning projects.

  Result  The proposed method is compared with the industry standard for reliability evaluation of medium-voltage distribution networks, and the calculation accuracy error is within 11%.

  Conclusion  The proposed method achieves a certain computational accuracy. It can meet the needs of rapid evaluation of reliability improvement effect of large-scale rural distribution network planning projects, and effectively improve the quality of distribution network planning.
