摘 要: 针对大型输电线路在数据传输时会延长调度时间,为了缩短大型输电线路的智能三维调度仿真分析的时间,提出大型输电线路的智能三维调度仿真分析。通过输电线路数据利用率可调度分析和输电线路的响应时间可调度分析,明确了输电线路数据利用率的可调度分析存在的缺点;根据数据信息的传输时间具有不确定性,构建输电线路三维调度适应度函数;最后利用输电线路三维調度仿真平台,实现了大型输电线路的智能三维调度仿真分析。结果表明,提出的仿真分析方法相比于传统仿真分析方法,在三维调度过程中数据传输的响应时间缩短了3.7 s。

Abstract: In view that the scheduling duration of large transmission lines will be prolonged during data transmission, an intelligent three?dimensional dispatching simulation analysis on large transmission lines is proposed to shorten the duration of intelligent three?dimensional dispatching simulation analysis. The shortcomings of schedulable analysis on the data utilization rate of transmission lines are clarified by the schedulable analysis on the data utilization rate of transmission lines and that on the response time of transmission lines. In view that the transmission duration of data information is uncertain, the fitness function of three?dimensional scheduling of transmission lines is constructed. A three?dimensional dispatching simulation platform for transmission lines is used to complete the intelligent three?dimensional dispatching simulation analysis on the large transmission lines. The results show that, in comparison with the traditional simulation analysis method, the response time of data transmission of the proposed simulation analysis method in the three?dimensional scheduling process is shortened by 3.7 seconds.
Keywords: transmission line; three?dimensional scheduling; schedulable performance; fitness function; simulation platform; response time
