、ABB REF541KM118AAAA If the raster or snap is active, the object can only be placed in a fixed position; Therefore, it is possible to better align objects. Redundant connections are physical connections between two redundant partners used to synchronize redundant data. Redundant links perform synchronization between the primary and secondary nodes of redundant partners through redundant links. The first synchronization between redundant controllers runs in parallel with “loading the entire site” or “loading changed objects”. First, load the operating system into the auxiliary program, then the user program, and finally the current process data. Once the first synchronization is successfully achieved, both redundant stations are transmitted to state synchronization. From now on, the data will be periodically adjusted between the two controllers. Redundant switching occurs when the active controller (master node) detects a problem or the switch has been actively triggered, such as through operator operation.

The structure of intelligent feeder terminal: Intelligent feeder terminal generally consists of control part, data processing part, communication part, and power supply part. Control part: Energy storage, closing operation, and opening operation of circuit breakers. Data processing: Integrated FTU, relying on FTU to complete data collection and processing. Communication part: integrated communication module, 4G wireless communication, fiber optic communication, etc. Power supply: Built in battery or supercapacitor, power supply includes AC/DC220, DC48.DC24, etc. The previous auxiliary node is the new main node and takes over the further execution of the program

The function of the feeder protection measurement and control device is an important protective device in the power system. Its main function is to quickly remove faults and protect the stable operation of the power system in the event of a short circuit, grounding fault, or other abnormal situation in the feeder. It can sense abnormal current and voltage signals in the power system, compare them with pre-set fault protection conditions, and quickly cut off the fault link when a fault is detected, preventing the fault from spreading to the power grid. The working principle of the feeder protection measurement and control device is based on the current and voltage sensors installed on the feeder, which detect, measure, and process fault signals to determine and quickly remove faults. It adopts digital signal processing technology, which can quickly and accurately detect feeder faults, achieve rapid fault removal, and ensure the stable operation of the power system
