【摘要】：配电网抢修作为配电系统管理的一个重要环节,因其将直接影响电力企业供电质量的稳定性和可靠性,并进一步影响用户对供电企业的满意程度,而越来越受到人们的关注。传统的配电网抢修模式主要由抢修指挥人员依据经验和不全面的抢修任务信息来进行调度安排,在配电网规模越来越复杂的今天,其局限性渐渐凸显,为了改善传统配网抢修模式资源配置不合理、抢修效率低下的现状,以多重信息系统为基础的智能配网抢修模式已成为一种发展趋势。本文以国内外相关文献为基础,旨在研究抢修资源受限条件下基于抢修任务的配电网抢修资源配置与调度问题。首先,本文全面分析了现有传统配网抢修模式所存在的问题及智能配网抢修模式的工作流程和应用前景,阐述了资源受限项目调度问题的核心思想和基本理论。其次,按照故障发生规模,将配网抢修的研究对象分为两类：一是常规状况下故障点较少、时间较为宽松、抢修资源有限且不变的情况；二是突发状况下造成大规模电力故障、时间较为紧迫、抢修资源有限但会得到补充的情况。然后,针对常规情况,深入分析了配电网中抢修任务的特点以及抢修所受到的网络关系、资源数量、节点距离等限制条件,建立了常规配网抢修资源配置与调度模型,结合资源受限项目调度理论及串行进度生成机制,提出了符合配电网实际情况且能够实现就近抢修的配网抢修串行进度生成机制以生成资源配置与调度方案。之后,在前面的研究基础上,针对突发事件造成的大规模电力故障发生的情况,考虑了应急电源车投入使用后的影响,提出了两步式模型优化求解方式。最后,将本文提出的配网抢修串行进度生成机制与SA算法结合,以搜寻满足既定目标的最佳抢修资源配置与调度方案,并通过算例仿真验证了所提模型及算法的正确性及有效性。
[Abstract]:As an important part of distribution system management, distribution network emergency repair has attracted more and more attention because it will directly affect the stability and reliability of power supply quality in power enterprises, and further affect the satisfaction of users to power supply enterprises.The traditional distribution network emergency repair mode is mainly carried out by the emergency repair command personnel according to the experience and incomplete repair task information to arrange the dispatch, in the distribution network scale more and more complex today, its limitation gradually highlights.In order to improve the current situation of unreasonable resource allocation and low efficiency in the traditional distribution network emergency repair mode, the intelligent distribution network emergency repair mode based on multi-layer information system has become a trend of development.Based on the domestic and foreign literature, this paper aims to study the distribution network emergency repair resource allocation and dispatch problem based on the emergency repair task under the condition of emergency repair resource constraints.Firstly, this paper comprehensively analyzes the existing problems of the traditional distribution network repair mode, the workflow and application prospect of intelligent distribution network rush repair mode, and expounds the core idea and basic theory of resource-constrained project scheduling problem.Secondly, according to the scale of fault occurrence, the research object of distribution network emergency repair is divided into two categories: one is that there are fewer fault points, the time is looser, and the resources for rush repair are limited and invariable under the normal condition; the other is the large-scale electric power failure caused by the sudden situation.Time is tight, urgent repair resources are limited but will be replenished.Then, aiming at the general situation, the characteristics of rush repair task in distribution network and the network relation, resource quantity and node distance are analyzed in depth, and the model of allocation and dispatch of emergency repair resource in conventional distribution network is established.Based on the theory of resource constrained project scheduling and the mechanism of serial schedule generation, this paper puts forward a serial schedule generation mechanism of distribution network rush repair, which accords with the actual situation of distribution network and can realize the urgent repair in the vicinity to generate resource allocation and scheduling scheme.Then, on the basis of the previous research, considering the influence of the emergency power vehicle after the use of the emergency power vehicle, a two-step model optimization method is proposed to solve the large scale power failure caused by the emergency.Finally, the serial schedule generation mechanism proposed in this paper is combined with SA algorithm to search for the best resource allocation and scheduling scheme to meet the established objectives.The correctness and validity of the proposed model and algorithm are verified by an example.
