基于网络拓扑结构的全网潮流计算模型自动生成

The Automatic Generation of Power Flow Calculation Model for Whole Power Grid Based on Network Topology

针对分布式潮流计算所必需的各地人员协同配合工作的难题,在分析了上下级调度和同级调度关系的电网潮流数据文件自动合并的基础上,提出一种基于网络拓扑结构的全网潮流计算模型自动生成的方法。该方法采用计算机图论技术,将EMS电网模型转化为电力系统分析综合程序(PSASP)能识别的潮流文件,并根据EMS网络模型中的电网设备命名唯一性,以潮流文件为载体,进行各级调度电网模型的裁剪和拼接,形成详细全网潮流计算模型。实际应用证明本文提出的全网潮流计算模型自动生成技术可行有效。

Due to the difficulty in coordinating the co - work of all staffs who are needed for distributed power flow cal- culation, based on network topology according to the analysis on the automatic merging of power flow data files for vertical and parallel dispatching modes, the automatic generation method of power flow calculation model for whole power grid is proposed. By using of computer graph theory, the proposed approach can convert power grid model in EMS format into power flow files recognized by PSASP program, and the power grid models for every dispatching are divided and merged based on power flow files according to the uniqueness in naming elements in the power grid models in EMS format, then the calculation model of whole power flow is built. Its application in Anhui province verified that the proposed method is feasible and has a good application prospect.
