                Centralized Protection and Control (CPC) System within a Substation

CPC is Fifth gen protection and control system enhancing digital substation. CPC system is comprised of high-performance computing platform(s) capable of providing protection, control, monitoring, communication and asset management functions by collecting the data those functions require using high-speed, time synchronized measurements within a substation. 

As shown in block 5, IMU sends voltage and current sample values to CPC using 61850-9-2. Process unit status monitoring and its control is also done through IMU.
