基于虚拟DSP的变电站激光自校验技术研究

目前激光自校验是变电站自校验的重要方式,但由于变电站激光自校验存在运行成本高,使用寿命短等缺点,难以广泛使用。针对这一类问题,提出了一种基于虚拟DSP的变电站激光自校验技术。它通过虚拟定时中断实时接收变电站调节电压模块接收的操作命令和编写的虚拟DSP数据,利用加减速处理器改善变电站电流稳定性,利用定时插补程序提高变电站电压的定时准确度。通过插补后的动态坐标和刷新后的变电站数字信号形成映射,由此完成变电站激光自校验,降低变电站激光自校验成本,提高变电站电压稳定性。仿真实验结果表明:所提方法运行成本低,实用效果较好。

Laser self-calibration technology of substation based on virtual DSP

At present, the laser self-calibration is an important way of self calibration in substation, but it is difficult to be widely used because of its high cost and short service life. Aiming at this kind of problem, this paper proposes a self calibration technique based on virtual DSP in substation. It begins by virtual real time receiving substation voltage regulation module receives the command and virtual DSP data prepared by the use of acceleration and deceleration processor to improve substation current stability, using the timing interpolation procedure to enhance the substation voltage and timing accuracy. Through the dynamic coordinates of the interpolation and the mapping of the digital signal after the refresh, the self calibration of the transformer substation is completed, the laser self calibration cost is reduced, and the voltage stability of the substation is improved. The simulation results show that the proposed method has low running cost and good practical effect.
