How can i get fundamental active / reactive power from ade7878

Question

Hello. 
 The ade7878's datasheet states that it uses fundamental active and reactive power. 
 However, I don't know how to get fundamental active and reactive power's value. 
 Is there any way to read the three-phase fundamenatal active and reactive power values? 
 Thanks.

Energy is just power over time. If linecyc is set to a small value say 100ms you can calculate the average power needed to give you that whr. The smaller the time window the closer you will get to the actual power. 
 
 The ADE9000 might be a better option if you need specific registers for Fundamental VAR and WATT)
