线损管理系统中电网模型的建立

Grid Model Development in Line Loss Management System

针对现有线损管理系统电网模型中存在的主配网没有直接连通、二次设备的测量作用没有被充分发挥的问题,提出了建设一种连通主配网、关联一次设备与二次设备的电网模型;通过一对一的数字化建模方法,建立一次设备与二次设备的分层模型连通主网、配网,除去等值连接的二次工作量和兼容性问题;设计二次设备的关口属性树建立一次设备与二次设备的关联关系,避免信息系统中关口与实际关口不符的问题;模型的搭建在SG-CIM的规范下进行;电网模型建立后,遵循SOA架构设计线损管理系统,实现电网模型的可重用管理及线损的实时管理。

There is no direct communication between the main and distribution network in the existing grid model of line loss management system,and the measuring role of secondary device is not full.Aimed at these problems,the proposal to construct a grid model which main and distribution network is connectivity,primary equipment is associated with secondary equipment is presented.Establishing hierarchical model of primary equipment and secondary equipment which communicate the main and distribution network by one-to-one digital modeling method,to remove the secondary workload and compatibility issues of equijoins;Designing gateway property tree of secondary equipment which establish a relationship with the primary and secondary equipment,to avoid the gateway in information systems inconsistent with the actual;the model is built in SG-CIM＇s specifications.After building the grid model,designing the line loss management system which follows the SOA architecture,to implement grid model＇s reusable management and real-time line loss management.
