8.7.8 Operation Mode
COSPHI Control operates in RPC (Remote Power Control) and internal modes according to communication
status to control power with Fixed COSPHI and Fixed Q.
Figure 55: Transition of RPC mode and Internal Mode
1. RPC mode
While HMI is modifying XCU’s {Remote Power Control}, {COSPHI RPC Reactive Power} and {COSPHI RPC
Power Factor} parameters with two-minute interval, COSPHI Control operates in RPC mode. In RPC mode,
it operates according to {Remote Power Control}, {COSPHI RPC Reactive Power}, and {COSPHI RPC Power
Factor} modes.
2. Internal mode
If RPC mode parameter such as {Remote Power Control}, {COSPHI RPC Reactive Power}, and {COSPHI RPC
Power Factor} is not be modifi ed within fi ve minutes, XCU will operate in Internal mode. In Internal mode,
COSPHI control operates according to internal mode parameters such as {COSPHI Internal Reactive Power}
and {COSPHI Internal Power Factor}, {Remote Power Control} parameter does not infl uence on the active
power.
