Abstract
Node admittance matrix is a mathematical model which is widely used in power system analysis and calculation,and is the base of power system analysis and calculation,the correct calculation of admittance matrix has very important significance.The paper analyzes in detail the questions such as node and branch numbering of three sequence network,YN/d transformer connection＇s calculation in zero sequence admittance,multi-lines processing,and the program is improved.The result shows that the program can calculate node admittance matrix of power system correctly and is applied to actual project successfully.关键词
