Dynamic List Creation for Power System Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy management systems in utility companies face challenges in providing adequate situational awareness, leading to potential catastrophic failures due to human errors caused by factors like data overload, attention tunneling, and complexity, which existing sophisticated algorithms and intelligent grids cannot fully mitigate.
Innovation Solution
The development of methods to create dynamic lists from selected areas of a power system, allowing operators to define and display vital information for network elements, using rubber-banding or lassoing to select areas, and generating lists that can be saved and recalled for future use, enhancing situational awareness and reducing operator workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sophisticated algorithms and intelligent electronic devices are used to process field data, then data processing capability is improved, but operator workload and complexity increase leading to human errors
Solution Approach 1:
The patent introduces dynamic lists as an intermediary tool between the complex power system and operators. These lists automatically extract and prioritize critical information from the system data, serving as a mediator that reduces the cognitive burden on operators while maintaining high data processing capability through automated selection and presentation of relevant parameters
2Loss of information
If more data is provided to operators for situational awareness, then information completeness is improved, but attention tunneling and data overload occur
Solution Approach 1:
The patent applies local quality by providing different information presentations tailored to specific operational contexts. Dynamic lists are configured to display different parameters and levels of detail based on the selected area of the power system, ensuring operators receive comprehensive information where needed while avoiding overload in other areas through selective information presentation
3Reliability
If operators are trained to master complex information, then situation awareness is improved, but training time and operational stress increase
Solution Approach 1:
The patent implements self-service through dynamic lists that automatically adapt to operator needs and system conditions. The system self-regulates information presentation based on predefined criteria and real-time system state, reducing the burden on operators to manually filter and prioritize information, thereby improving situation awareness without requiring extensive training time
Data Source
AI summary
Methods are provided for creating dynamic lists from selected areas of a power system of a utility company. The utility company has an energy management system with a control panel. The energy management system is used to access one or more source displays of a site. Rubber-banding or lassoing is used to create selected areas from at least a portion of the source displays. Lists are created dynamically. Operator defined information is displayed for each element type in a list of network elements from the selected areas that have been rubber-banded or lassoed.
