数据驱动的电网主设备异常运行自动控制

Data driven automatic control of abnormal operation of main equipment in power grid

由于输出电压和电流突变,导致自动控制设备存在输出功率控制效果不佳的问题,因此提出数据驱动的电网主设备异常运行自动控制方法。该方法通过压缩感知的方法采集电网数据,并基于数据驱动的VSDModel方法降维电网数据,设计智能控制终端,根据采集的制动电流值和差动电流值,通过开关隔离故障恢复电网正常运行,实现电网主设备异常运行自动控制。实验结果表明,所提方法的电力电子输出电压为正常状态,输出电流未超出允许范围[-90,90],输出功率稳定,具有较高的应用价值。

Due to the sudden change of output voltage and current,the control of power grid equipment is abnormal,resulting in the problem of poor output power control effect.Therefore,a data driven automatic control method for abnormal operation of power grid main equipment is proposed.This method collects power grid data by means of compression sensing,and reduces the dimension of power grid data based on the data driven VSDModel method.An intelligent control terminal is designed,which recovers the normal operation of the power grid through switch isolation fault according to the collected braking current value and differential current value,and realizes the automatic control of abnormal operation of the main equipment of the power grid.The experiment results show that the power electronic output voltage of the proposed method is normal,the output current does not exceed the allowable range[-90,90],and the output power is stable,which has high application value.
