Abstract :
This paper briefly reviews the selecting procedure of voltage grade on 750 kV high voltage transmission project (750 kV HVTP) and introduces the short-terms and mid-terms planning schemes. After the 4th tie line is established between Shaanxi and Gansu provinces, the influence of this 750 kV HVTP to Shaanxi electric grid is analyzed from both the power flow distribution of tie line between provinces and the reactive voltage level. Then this paper analyzes the stability levels of several crucial power flow sections of Shaanxi electric grid for the year 2006. At last, the necessity of the 4th tie line development is further discussed
