Parameters
8.7.6 COSPHI Control Mode
COSPHI control operates with five reactive and active power control ways according to {COSPHI Control Mode}
setting.
No. Power control Description Relative Parameters
1 Fixed P Control the maximum active power with {Remote
Power Control} parameter value (% of max rated
power). {Remote Power Control}
2 Fixed COSPHI Control the maximum active power with {Remote
Power Control} parameter value (% of max rated
power). Control power factor with parameter value of
{COSPHI Internal Power Factor} or {COSPHI RPC Power
Factor} according to present RPC status. {Remote Power Control}
{COSPHI Internal Power
Factor}
{COSPHI RPC Power Factor}
3 Fixed Q Control the maximum active power with {Remote
Power Control} parameter value (% of max rated
power). Control reactive power with parameter value
of {COSPHI Internal Reactive Power} or {COSPHI RPC
Reactive Power} according to the present RPC status. {Remote Power Control}
{COSPHI Internal Reactive
Power}
{COSPHI RPC Reactive
Power}
4 COSPHI (P/Pn) Control power factor to match the graph of maximum
10 continuous {COSPHI_n} and {P_n} pairs. {COSPHI_n}, {P_n}
(n = 1~10)
{COSPHI(P/Pn) {Ramp Time}
5 Q(V) Control reactive power infusion from inverter to grid
when grid voltage is between rated range. The grid
voltage range where Q(V) function is possible is
determined by {Q(V) Control Deadband} and {Q(V)
Control K Factor}. {{Q(V) Control Deadband}
{Q(V) Control K Factor}
{Q(V) Control Ramp Time}

8.7.7 Communication between Components
COSPHI Control enables remote control of reactive and active power by setting reference of reactive and active
power by communication between Prolog, MMI, and XCU. Here are the communication methods between
each component.
1. User activates COSPHI Control by Prolog.
2. Prolog sends a COSPHI Control massage at two-minute intervals.
3. MMI interprets the COSPHI Control message from Prolog to modify parameters of XCU.
4. XCU operates according to the modified parameter by MMI.
5. COSPHI (limited to Fixed COSPHI and Fixed Q) has two overlapping parameters for RPC and Internal modes,
and MMI modifies the parameter for RPC mode only. If the relative RPC mode parameter is not modified
longer than five minutes, XCU will operate according to the parameter for internal mode.
