[0143] 1. By reusing the measurement and control optimization sub-periods divided in step S1, the timing of voltage monitoring and current monitoring is aligned. The measurement and control optimization sub-periods are dedicated to in-depth data analysis, avoiding resource consumption of global monitoring. For example, during periods of frequent voltage fluctuations, the monitoring sub-period intervals can be automatically extended to focus on key abnormal characteristics, significantly improving monitoring efficiency.

[0144] 2. It integrates the average voltage value (Vpz) of the time period, the average voltage interval time ratio (Vsb) and the stable voltage duration ratio (Vwx). Among them, the average voltage value reflects the baseline level of power supply quality and identifies overvoltage / undervoltage anomalies. The interval time ratio evaluates the voltage fluctuation frequency by the length of time the voltage stays in the average interval. The stable duration ratio calculates the voltage stable interval ratio based on the dynamic threshold (Vpz±Vbc) and quantifies the voltage fluctuation amplitude. The three are generated through a weighted formula to generate the time period voltage monitoring coefficient (Vjx), upgrading the single voltage value monitoring to a three-dimensional assessment of voltage stability, volatility and continuity, significantly improving the accuracy of hidden danger identification.

[0159] 2. Generate dynamic preset coefficients based on historical FTU switching records, enabling the control strategy to adapt to the environment and effectively reducing the risk of misoperation. The resource-focused design of the measurement and control optimization sub-period avoids multi-task parallel conflicts and ensures the independent execution of key decision-making processes.

[0160] 3. Through the current-voltage joint control mechanism, closed-loop management of fault precursor capture, fault process protection and post-fault recovery is achieved, which greatly enhances the stable operation capability of the distribution network and provides key technical support for the construction of new power systems.

[0161] In this application, if a corresponding calculation formula appears, the above calculation formula is dimensionless and its numerical calculation is performed. The weight coefficient, proportional coefficient and other coefficients in the formula are set to a result value obtained by quantifying each parameter. Regarding the size of the weight coefficient and the proportional coefficient, as long as it does not affect the proportional relationship between the parameter and the result value, it is acceptable.
