answer:
The intelligent transformation of conventional substations needs to realize primary equipment status monitoring, information modeling standardization, information transmission network, advanced functions and intelligent auxiliary systems.
(1) Primary system transformation: Add a condition monitoring function unit to the key primary equipment of the substation, and the status analysis result is based on DL/T 860 (Substation Communication Network and System” (ie IEC 61850) to achieve interaction with related systems.
(2) Secondary system transformation: At this stage, the protection adopts direct mining and direct jump mode, the whole station realizes the standardization of communication protocol, further improves the station control level function, and adds intelligent advanced applications according to demand.
