| Abstract: | It is common that voltage exceed the upper limit while the load is low in the 500kv power system,it may bring bad influence to security and equipments even effect the stability of the grid.This paper introduces the ordinary principle of voltage increase in the end of the transmission lines,the main function of the reactor in power grid,and take an example to prove that reactors can decrease the voltage at the end of transmission line. |
