摘要
传统配电网馈线长时间处于重过载状态,导致馈线元器件老化加速,馈线使用寿命缩短,增大了馈线发生故障的概率,不利于配电网供电可靠性.结合目前流行的微服务架构提出一种基于联络线路负荷均摊和预备力最大的负荷倒出方法,实现配电网馈线发生重过载时快速倒出负荷.基于微服务的应用架构,将配电网重过载负荷倒出功能的各个功能模块解耦,并结合云原生十二因子和康威定律等设计理念将配电网负荷倒出业务划分为区域负荷计算微服务、过负荷监视微服务、负荷倒出微服务和操作票执行微服务.基于某云平台开展的负荷倒出功能验证表明,基于联络线路负荷均摊和预备力最大的方法可以快速倒出更为接近的负荷,避免了不必要的用户停电,同时也提高了用户的用电效率.
Abstract
Conventional distribution network feeders commonly suffer long-time heavy overload state,which accelerates the aging of feeder components,reduces the service life of feeders,increases the probability of feeder faults,and thus affects power supply reliability of distribution networks.In view of this,through introducing the current prevailing microservice architecture,the present study proposes a load reversal method which is based on load sharing and maximum reserve capacity of interconnection lines and can achieve rapid load reversal in the event of heavy overload encountered by distribution network feeders.Based on the application architecture of microservices,the heavy overload reversal function is decoupled into various functional modules.And by combining design concepts such as the Cloud Origin Twelve Factors and Conway's Law,the distribution network load reversal business is divided into regional load calculation microservices,overload monitoring microservices,load reversal microservices,and operation ticket execution microservices.Finally based on a certain cloud platform,the load reversal function verification is carried out.The verification results show that the method based on load sharing and maximum reserve capacity of connecting lines can quickly reverse closer loads,avoid unnecessary user power outages,and also improve user electricity efficiency.
