Hello everyone,

I have PSSE data with negative resistance and reactance for certain branches. Does it have any meaning (i.e. convention, direction etc.) or is more likely a data problem?

Negative resistance and reactance can be seen when: a. there are series capacitors modeled as branches b. equivalencing is done on a larger power system network model.

Negative R/X is more likely a data problem unless you have the two items mentioned above.
