Research On Practicability Of Static Security Analysis For A District Power System

With the continuous expansion of the power system and the opening of powermarket,the scale of trade connection will be continuously expanded,so, operation of theelectric power system desiderate increasingly a high effective electric power system forthe static state safety analysis software,which can help them nip in the bud by analysingoperation ways of those electrified netting and security level of power system。Thispaper introduces the improvement power grid connection analysis's method. A newsolution is put forward-the method of searching busbar automatic transfer switch(BATS)based on twice topology analysis。 The traditional security assessment method areintroduced and compared,and it is put that the accurate power flow is used to achievesecurity assessment。Finally, safety countermeasure and fault restoration function areintroduced,and these functions are verified by the practical calculation examples basedon Lanzhou local distribution network。...
