Abstract

This paper presents the results of a project which is undertaken in order to develop a flexible visualization tool to be used mainly by power system operators. The project concentrated on two application functions, namely the power flow and the state estimation. One of the essential goals of the envisioned tool is to aid system operators by providing images of the system with easily identifiable characteristics related to violations of various operating limits. In addition, the tool is expected to illustrate deficiencies associated with the existing metering system both from the point of view of metering design as well as accuracy. The result is a user-friendly 3D graphic interface for the stated two power system applications. In power flow analysis mode, animation and bus contouring technique is used for visualizing power flows and bus voltages. In state estimation mode, color contour is used to visualize different observable islands and bad measurements which are identified through the largest normalized residuals test. Effectiveness of the tool is illustrated via different scenarios which are created using the IEEE 118 bus system as an example

电力系统状态估计的三维可视化

本文介绍了一个主要供电力系统操作人员使用的灵活的可视化工具的开发项目的成果。本课题重点研究了两个应用功能，即潮流和状态估计。所设想的工具的基本目标之一是通过提供具有与违反各种操作限制相关的易于识别特征的系统图像来帮助系统操作员。此外，该工具有望从计量设计和准确性的角度说明与现有计量系统相关的缺陷。其结果是一个用户友好的三维图形界面，为上述两种电力系统的应用。在潮流分析模式中，利用动画和母线轮廓技术实现潮流和母线电压的可视化。在状态估计模式中，通过最大归一化残差检验识别出不同的可观测孤岛和不良测量值，并采用彩色轮廓对其进行可视化。通过以IEEE 118总线系统为例创建的不同场景说明了该工具的有效性
