Evaluation method and device for transient overvoltage of multi-output DC system |
| abstract |
The invention discloses a method and a device for evaluating transient overvoltage of a multi-feeding direct current system. The method includes: establishing a second-order corrected power flow iteration equation of the multi-feeding direct current system, and determining the relationship equation between reactive power and voltage ; Transform the relationship equation of reactive power and voltage into the relationship equation of reactive power and voltage including the extended admittance matrix; solve the minimum eigenvalue and eigenvector of the extended admittance matrix; convert the minimum eigenvalue of the extended admittance matrix The value and the eigenvector are substituted into the relationship equation of reactive power and voltage including the extended admittance matrix to solve the overvoltage of the DC sending end bus corresponding to each DC line during DC blocking; The bus overvoltage at the DC sending end is compared with a preset voltage threshold to determine whether the multi-output DC system has transient overvoltage instability. The present invention can improve the accuracy of transient overvoltage evaluation of the multi-output DC system. |
