摘要
为了减少手工计算大量重复性工作,根据大庆油田35 kV电压等级配电网的现状,提出了各种配电网继电保护整定计算的计算机模型。采用树状模型来描述电网结构,巧妙地处理系统T接线中的T节点配合问题,建立了用于描述电网的参数数据库。并在此基础上研制开发了能够适用于规模较大、结构复杂的配电网保护计算的软件系统,实现动态生成并打印水晶报表。该软件能提高继电保护整定计算的速度和正确性。
To get rid of countless repeated handwork in relay protection calculation ,according to the present characteristics of Daqing Oil Field 35 kV distribution network, kinds of protection calculation computer models are put forward. A tree-like model and a proper parameter database are introduced to describe the network. T-connected node problem is ingeniously solved. Finally ,a protection calculation software system for the distribution network is developed, which can generate the reports automatically and adapt to complex extended distribution network. The proposed software can enhance the rapidity and accuracy of relay protection calculation.
