摘要:
      针对配电终端的选址选型问题,首先提出考虑通信链路失效的9状态转移模型;其次在考虑配电“二遥”和“三遥”终端不同通信组网模式的链路失效以及误/拒动故障经济损失条件下,提出一种计及通信可靠性影响的综合停电损失计算方法,并与配电终端建设成本共同构成目标函数;然后基于节点重要度理论并计及供电可靠性与投资成本的双重约束,提出一种配电终端分阶段选址选型策略。算例结果表明,所提出的选型选址分阶段规划方法能够稳定可靠地得到满足约束条件的可行解。在传统基于智能算法的一体化规划方法陷入局部最优解,甚至无法得到可行解的场景下,所提出的分阶段规划方法仍然能够保证解的质量。
Abstract:
      For the selection of site and type of power distribution terminals, the 9-state transition model considering communication link failure is firstly proposed. Secondly, the link failure of different communication networking modes of power distribution terminals without tele-control function and power distribution terminals with tele-control function is considered. Under the condition of economic loss caused by error/rejection failure, a calculation method of integrated power outage loss considering the influence of communication reliability is proposed, and together with the construction cost of distribution terminal, the objective function is used for the selection. Then, combined with the theory of node importance and considering the dual constraints of power supply reliability and investment cost, a staged selection strategy of site and type for power distribution terminals is proposed. Results of the example show that the proposed staged site and type selection planning method can obtain a feasible solution that satisfies the constraints stably and reliably. In the scenario that the traditional intelligent algorithm based integrated planning method falls into the local optimal solution or even unable to obtain the feasible solution, the proposed staged planning method can still guarantee the quality of the solution.
