【Abstract】 An optimization and centralized control system for reactive power/voltage in the whole area network, which is implemented by means of SCADA in dispatching automation, is put forward in this paper. The optimization objectives of this system are as follows: To reduce the line loss in the whole network to be as small as possible, and to improve the voltage eligibility at each node to be as high as possible. The control objects of the system are the on load tap changer for voltage regulation transformers in all substations and the switching on and off ofcapacitors. Theexperienceof applying this system in Taizhou power network shows that designing aim of this system is realized.更多还原
