Online Health Assessment Method for Substation Monitoring System Equipment

Abnormal health conditions in substation monitoring equipment can lead to a decline in system performance, even causing functional failures that threaten grid security. However, current research on health assessment for secondary equipment primarily focuses on protective devices. This paper proposes an online health assessment method for substation monitoring system equipment. First, a three-level health assessment index system is constructed for substation monitoring equipment. Then, a fuzzy comprehensive evaluation method is proposed for the online health assessment of substation monitoring equipment. Finally, practical examples verify the effectiveness and engineering applicability of the proposed method.
