Abstract

The invention provides a safety assessment and dynamic regulation and control method for a power grid line. The safety assessment and dynamic regulation and control method comprises the steps: 1, establishing a power grid line safety assessment index system; 2, setting a power grid line safety index factor set U; 3, setting a safety comment set V; 4, calculating the weight value of the power gridline safety assessment index according to an analytic hierarchy process, and obtaining the weight vector of each level of index; 5, determining a fuzzy relation matrix R; 6, constructing a comprehensive safety assessment model; 7, obtaining the safety assessment level of the power grid line according to the comprehensive safety assessment model; and 8, carrying out dynamic safety regulation and control according to the obtained safety assessment level, and carrying out medium and short term safety regulation and control if the safety assessment level is a high influence or a high influence; ifthe safety assessment level is relatively low in influence, performing day-ahead safety regulation and control; and if the safety assessment level is low in influence, performing intra-day safety regulation and control.

Description

technical field [0001] The invention belongs to the technical field of electric power safety control, and in particular relates to a method for safety evaluation and dynamic control of power grid lines. Background technique [0002] With the rapid development of my country's economy, my country's power grid has also developed rapidly, which is manifested in the continuous increase of installed capacity, continuous increase of load power, continuous improvement of operating voltage level, and continuous expansion of power grid scale. In order to meet the growing demand for electricity, my country will build 29 UHV lines with a clear structure of "five horizontal and five vertical" at the sending and receiving ends, and connect six large-scale power grids in series: Northeast China Power Grid, North China Power Grid, Central China Power Grid, East China Power Grid, Northwest Power Grid and Southern Power Grid. The regional power grid forms a large grid pattern of AC and DC hybr...
