Abstract
The present invention provides method and apparatus for reassigning switched capacitors which are lost as a result of circuit reconfiguration. A power distribution network includes a plurality of substations. Each substation includes a master controller which manages switching operations of a plurality of load regulation capacitors. The capacitors which are a part of the same circuit as a given master controller are normally under the control of that master controller. Each time a load regulation capacitor is connected or disconnected, a change in the voltage level and the VARs level is observed on the distribution line to which the capacitor was connected. When a load regulation capacitor is reconfigured so that it no longer is a part of a distribution line controlled by its associated master controller, the master controller connects or disconnects the capacitor and polls the neighboring master controllers to determine which of the neighboring controllers has observed a significant change in the VARs or voltage level on their associated distribution lines at the time of connection or disconnection. The capacitor is then reassigned to the control of the neighboring controller whic…
