Comments

• • If a SynchronousMachine is not associated with a ReactiveCapabilityCurve, then the minQ and maxQ attributes will be used.- If a ReactiveCapabilityCurve is supplied, then the minQ and maxQ attributes are not required.- If a synchronous condenser is being modeled so that there is no capability for real power output, the SynchronousMachine is not required to be associated with a GeneratingUnit. In this case, the type and operatingMode attributes must both be set to condenser.
