| In this paper, focus the power network structure change, especial the power network islanding, an algorithm of dynamic power flow for more electric islands is proposed. It designs a new method of chained list storage for admittance matrix and a new algorithm of amend admittance matrix. When the power network structure changed, admittance matrix can be amended to fix new network structure quickly by this algorithm. In this paper, dynamic power flow calculation was put into classic islanding power flow calculation. It can get good result in calculate power flow by this algorithm. It shows that it can meet the challenge of validity, accuracy, real-time, adaptability and convergence in DTS system power system calculation. The algorithm has been used in the power flow calculation for the supply network of FengFeng. |
