摘　　要：新型电力系统的加快推进将让配电网发生翻天覆地的变化,配电网主站也将面临新的挑战。高渗透率分布式电源接入配电网使得输配电网之间产生了双向功率流动,并且分布式能源受电网调频调峰需求响应、环境、国家政策等外界因素影响,使得新型配电网运行方式多变。频繁异动的电网模型和大容量的智能终端接入也对配电网主站运行的可靠性提出了严峻的挑战。对此,提出了一种适应新型配电网多变运行方式的终端定值管理闭环方法与系统,通过配电网主站系统终端定值定时召唤、定值跨区传输、定值在线校核、定值整定、定值下装、定值归档完整的管理闭环流程,为配电网终端离线定值与新型配电网多变运行方式失配造成的误动问题提供了一种解决方案,提高了新型配电网的供电可靠性和安全性。The rapid development of the new power system brings about dramatic changes in the distribution network,and also new challenges to the distribution network master station.The high-permeability distributed generation connected to the distribution network generates bidirectional power flow between transmission and distribution networks.The distributed generation is susceptible to multiple external factors such as the demand response to power grid′s frequency modulation and peak shaving,the surrounding environment,and national policy changes,resulting in continual variation in the operation mode of new distribution network.Moreover,the frequently abnormal power grid model and the access of large capacity intelligent terminals also pose a serious challenge to the operating reliability of the distribution network master station.This paper presents a closed loop method and system of terminal constant value management which is adaptable to the new variable operation mode of distribution network.Through the complete management closed-loop process consisting of links including constant value timing call,constant value cross region transmission,online verification,constant value setting,constant value downloading,and constant value archiving with respect to the distribution network master station system terminal,the proposed system can provide a solution to the maloperation problem caused by the mismatch between the terminal′s offline fixed value and the variable operation mode,thus improving the reliability and security of power supply of the new distribution network.
