4.7. COS"(P) Characteristic Curve
The value of the power factor cos" is controlled as a function of the active power with a presetting
characteristic curve. However, the network operator may provide different one for their power generation
plant depending on the network conditions. The prescribed COS"(P) characteristic curve has four
adjustable nodes and one cos" limit with default setting:
(The permissible range of cos" limit is 0.9~1.0 and for node setting is 0%~100%.)
(d) The COS"(P) characteristic curve with default setting
The output power capability of “COS"(P) characteristic curve” can be shown as:
(Green region means the permissible operating point, take 4kW model for example)
(e) Reactive output capability of COS"(P) Characteristic Curve
