摘要:
Fault interrupting devices and methods for controlling the same are disclosed. The fault interrupting devices may include a switch on an electrical power line and a controller configured to operate the switch. The methods for controlling fault interrupting devices may include gathering data, determining from the data that a fault has occurred, opening the fault interrupting device to interrupt the fault, analyzing the data, and determining whether the fault interrupting device can be reclosed based at least partially on the analysis of the data.
摘要:
A wireless secondary assembly is disclosed for use in an electrical distribution network. The secondary assembly may include a wireless source electrically connected to a first electric cable and adapted to emit an electromagnetic power signal. A wireless receiver is electrically connected to a secondary device and adapted to receive the electromagnetic power signal and convert the electromagnetic power signal to electricity to power to secondary device.
摘要:
A computer implemented method uses a database of detailed, comprehensive utility operating and financial information. The method comprises: (1) feature based matching or similarity based benchmark and focus group selection; (2) a performance assessment procedure comprising multi-perspective analysis; and (3) multi-attribute business profiling and performance improvement potential analysis. As part of the performance assessment step, data corresponding to different utilities in a selected benchmark group are compared with each other to find their strengths and weaknesses. Interpretation of these gaps provides the cause of such gaps. Composite ranking analysis is used so that a composite score of at least one utility business is obtained.
摘要:
Reliability assessment of a power system having an integrated component is provided by retrieving individual component failure rates associated with individual components of the integrated component. A failure time is modeled based on the individual component failure rates associated with individual components of the integrated component. Individual component maintenance times are retrieved associated with individual components of the integrated component. A maintenance time is modeled based on the individual component maintenance times associated with individual components of the integrated component. A reliability assessment is determined based on the interconnectivity of components of the power system, the modeled maintenance times, and the modeled failure times.
摘要:
A systematic approach is presented for the development and implementation of cost-effective transmission asset maintenance strategies. The overall concept and methodology are based on transmission reliability and risk management and address the value of preventive maintenance activities. This may help electric network utilities conduct maintenance policy assessment, region-wide criticality analysis, and optimal maintenance resource allocation and task scheduling.
