doi:10.11930/j.issn.1004-9649.201708088

Abstract

Abstract: The power transmission section is an important monitoring and analysis object for the safe and stable operation of the power grid and the emergency handling of the faults. Enhancing the monitoring capability of transmission section is helpful to understand the real-time operation of power grid, and effectively improve the early warning ability of power grid security. In order to meet the demand of grid operation dispatching, this paper studies a comprehensive evaluation method of transmission sections based on the analytic hierarchy process (AHP) and proposes the quantitative calculation indicators for the safe operation of the transmission sections; The Delphi method is introduced to make full use of the experience of operation dispatching experts to improve the AHP, so as to reflect the relationship between the multiple indexes and the operation state of the transmission sections, and achieve a comprehensive monitoring of the transmission sections. This method is applied in the control center of a regional power grid, and the results show that this method can effectively improve the monitoring capability of power transmission section.

Key words: transmission section, multiple indexes, comprehensive evaluation, monitoring, analytic hierarchy process
