Design and Application of Smart Transformer Service Area Based on TTU and SCB

There is a lack of effective management methods to obtain the information and data of devices in transformer service areas. Based on edge computing and IoT perception technologies, this paper proposes a low-voltage smart transformer service area scheme using intelligent transformer terminal unit (TTU) and smart circuit breaker (SCB). TTU is the edge computing device which is introduced to realize the local edge computing and tasks in transformer service areas. SCB is implanted in transformer service area to collect the information and data of devices, such as PVs and EV charging piles. A practical case for PV monitoring is introduced in this paper.
