Contact-line Transient Stability Analysis

In 2005, south five provinces( area) economy will continue the keeping increases quickly, the total top in need in electric power will still maintain the higher level. The electric power need of Guangdong will keep than increase quickly, Guangxi industrializes to turn the progress to push forward quickly with the town, electric power the need increase the total keeping in the higher level. But 2004 with 2005 expensive state charged barbed wire nets lack coal restriction of electricity serious, meeting because of electricity coal supply the shortage causes machine set stopped to carries or decline to lift a hand to the phenomenon seriously.In west gave or get an electric shock east sent engineering, be used as the expensive state, Guangdong, Yunnan, Guangxi hand over to remit aground of----s naturally bridge the electricity stands, is an expensivestate the conduct and actions send to carry the system primarily of a vital point orders, have a the line of contact for, the 200 KVs hands over the direct current passage, particularly with peacefully following to changethe ---- naturally bridge the second class electricity stands, theninstall antenna, sending with southern charged barbed wire net the expensive state charged barbed wire net to carry to connect with Guangxi with the system of Yunnan more directly together.In 2005, connect to also be shown along with a for widely fourth returning exchanges circuit setting up hurl producing, west electricity delivering circulating first way having to enhance, the charged barbed wire net of Yunnan and main net the enhance.When the direct current system occurrence breaks down, meeting enlargement to the impact of the exchanges system, but the direct current system transports the power more big, the direct current power recovers the motion of the process after exchanges system break down period with break down more big, to charged barbed wire net stability more disadvantageous.05 normal ways are next, the 500 KVs is each to send to give or get an electric shock the cross section current control in cross section extreme limit, it is any to return to an exchanges circuit three break down mutually and permanently, protect the right action, the system keeps stability, arbitrarily on returning to direct current single shutting the lock very, or big machine a demand for losing jumping empress system can keeping stability, main net can basicly satisfying sending electricity planning and normal power supply.It is opposite to break down in the other N-1 but talk, a stipulation for installing antenna peacefully following side third, weighing scales line naturally bridge side third , high the direct current of singlely very shutting lock etc. breaking down the most seriously, is affecting...
