配电网检修计划仿真系统研究与应用

随着电力企业信息化进程的不断深入和发展,电网公司的检修计划制定工作日益从传统的电话、书面申请审批过渡到网上作业方式。但是这种简单的工作方式的变化,并没有从根本上改变检修计划的制定过度依赖于检修专工的工作经验的弊病,而且所制定出的检修计划对电网所造成的影响也仍然只是停留在定性分析上,因此现场工作人员迫切需要一种便捷的工具,量化设备检修对电网所造成的影响,以辅助检修专工制定出更加合理的检修计划。配电网检修计划仿真系统采用公共信息模型对配电网进行建模,通过图形化的操作界面,自动维护配电网的拓扑关系。在检修专工制定检修计划时,通过对设备检修方式的模拟,系统将根据模拟后的网络结构进行潮流计算,对网络进行动态着色,并突出显示越限设备,以辅助检修专工进行相应调整。现场运行结果表明,配电网检修计划仿真系统具有良好的可操作性和实用性。

Research and application of maintenance scheduling simulation system for distribution network

As the development of electric power information project,most companies changed their maintenance work from original by phone or word into by Internet.But this simple change can not satisfy the requirement of the scheduling work,for it does not offer the information of how equipment maintenance affects the power network.So the plan makers want a convenience tool to help them make more reasonable maintenance schedule.The simulation system uses CIM to model distribution network.By graphics user interface,it forms the topology relationship of distribution network automatically.Also,the simulation system calculates load flow,colors network dynamically and gives overloaded equipment information.Practice application verifies the convenience and practicality of the simulation system.
