AI Technical Summary
Existing external circuit breaker control methods for electricity meters cannot reflect power fluctuations in a timely manner, resulting in inaccurate power calculations, a lack of flexible response capabilities, frequent circuit breaker operation, and inappropriate closing times, which affect the stability and security of the power system.
A dynamic adjustment mechanism based on the power change rate is adopted to construct a baseline power model based on periodic fluctuations and phase disturbances. Power data is acquired through non-uniform random sampling, and the time window and recovery time threshold are dynamically adjusted. Combined with the exponential decay factor and intelligent correction delay mechanism, the opening and closing control strategy is optimized.
It improves the accuracy and flexibility of power calculation, reduces the risk of false triggering and premature closing, enhances the adaptability and robustness of power equipment, and ensures the efficient and safe operation of the power system.
