Usually there are som e state variables going over its operating lim its in actual power system.The critical function of on- line reactive power/ voltage control package should first satisfy the operating security requirem ents in power system, that is keeping voltage within its regular span and furthermore decreasing active power loss on the basis of voltage security.A primal- dual interior point methodology is deduced through converting over- limitunequal constraints into equality constraints. In this paper the corrective schem e is obtained through solving an optimal problem with objective function as minim um sum of control variables action.And the selection of corrective variable and priority of over- lim ited constraints are also analyzed.It is proved by actual calculation that the method applied here has good efficiency to reduce problem size and correction tim es.
