Error in displaying line flows? #22

Closed AliHeggie closed 8 years ago

Sometimes the branch flows are not identified correctly from the input file (or calculated?).

For example in the attached case pLfrom, qLfrom, pLto and qLto are in columns 14 to 17 of the branch matrix as specified in the matpower case format. On branch 1 these should be 10.00000742 71.85183455 -10.00000194 -68.69556371 respectively. But this power flow data is not displayed correctly in the visualizer. The reactive power flow is correct but Active Power Forward is .1745 and Active Power Reverse is -.1745.

Sorry, I think this is my mistake for having voltage angle in radians rather than degrees in the example case.
