摘要:
高壓斷路器是電力系統的核心設備,其穩定可靠運行具有重要意義。高壓斷路器分合閘電流曲線能夠很大程度上反映高壓斷路器分合閘機構的運行狀態,因此文中研究了在幾種典型故障條件下,斷路器分合閘線圈電流的變化。隨機森林算法由于算法實現過程中的兩次隨機過程,使得算法過擬合風險大大降低,模型泛化能力大大增強。提出了使用隨機森林算法識別故障電流曲線,取得了很好的效果。
Abstract:
To identify the fault types of high-voltage circuit breaker accurately and reliably, a fault diagnosis method for high voltage circuit breaker is formed. In this paper, the reclosing coil current of HV circuit breaker under different conditions is analyzed, in order to extract time and current as characteristic parameters to form training set. Combining random forest algorithm (RF) with training set, random forest classifier is established to distinguish fault types of high voltage circuit breakers efficiently. Experiments show that the algorithm can accurately distinguish the fault of high voltage circuit breaker, which greatly improves the utilization rate and efficiency of HV circuit breaker.
