The step-by-step implementation measures to the whole power system reactive power optimization are proposed. As the first defence line against the voltage stability failure, the proposed method is scientific, practical and operable. 闂�(gu膩n)閸佃锛氱稉(j墨ng)婵熷宸� 鐒″姛鍔熺巼鍎�(y艒u)鍖� 闆诲 瀵︽檪鐩�(ji膩n)娓垏鎺у埗 Keywords:
