Optimal control of parallel operating arc-extinction colis in35kV distribution systems

A new solution is set forth to solve the problems caused by the parallel connection of arc-extinction coils,which utilizes the supervisory computer of dispatch center to control the con-nected networks.The way to realize the optimal control of every arc-extinction coils in connected networks is introduced.The subordinate computers send to dispatch center the dynamic data(the real-time coil setting,operative mode,etc)and static data(the capacitive currents of different opera-tive modes,etc)of substations.The supervisory computer carries out the real-time control to obtain optimal compensation according to the optimal control rules.
