电力行业的创新改革使10kV高压开关柜得到了广泛使用,于是文中针对变电站10kV高压柜的电气磨合问题,提出利用基于控制流的多线程自动控制方法。首先,针对开关柜电气磨合系统中产生的数据信号,利用线程技术将电气磨合数据作为数据采集线程的主要方向,根据采样定理将被采集信号频率设定为系统产生信号的两倍,通过运用奇偶分离符号变化法实现正交相干检波操作,可获得电气磨合采样信号;其次,为保证线程数据信号采集效率,可先构造多线程程序依赖图同时保存程序控制流数据信息,利用信息计算获知控制流和并行流可达到的节点集合,可判断出多线程数据采集的路径,将未达到节点集合的节点舍弃,从而达到多线...

The innovation of electric power industry makes the 10kV high voltage switchgear widely used, so this paper puts forward the method of multi thread automatic control based on the control flow in the 10kV substation. First of all, according to the data signal generated in the system running in electrical switchgear, using thread technology will run in electrical data as the main direction of data acquisition thread, according to the sampling theorem will be set to two times the signal frequency acquisition signal for the system, through the realization of orthogonal coherent wave construction o...
