Voltage pulse influence evaluation method in power grid

The invention belongs to an evaluation method, and particularly relates to a voltage pulse influence evaluation method in a power grid. The voltage pulse influence evaluation method in a power grid comprises the following steps: 1, collecting data, wherein data in a power grid are collected in real time; 2.judging, wherein an absolute error value is used for judging whether risks exist or potential risks exist or not; 3, fitting data fitting, when the potential risk exists, data fitting is carried out; 4, carrying out prediction, and predicting risk. The method has the advantages that throughtwo-stage judgment of the detection signal, whether the voltage pulse can cause harm to the power grid or not is accurately pre-judged; and through specific fitting parameters, it is ensured that a prediction result is accurate and efficient. 本发明属于评估方法，具体涉及一种电网中电压脉冲影响力评估方法。一种电网中电压脉冲影响力评估方法，包括下述内容：步骤一：数据收集；实时收集电网中的数据，步骤二：判断；用绝对误差值判断，存在风险、潜在存在风险或无风险；步骤三：数据拟合；当潜在存在风险时进行数据拟合；步骤四：预测；预测风险。本发明的显著效果是：通过对检测信号的两阶段判断，准确的预判出电压脉冲是否会对电
