Security Evaluation of UHV Synchronized Power Grid

It is researched whether if the security and stability performance of ultra high-voltage (UHV) grid could meet the requirements of power system security and stability criteria of China. Based on security and stability evaluation of UHV power grid, the possibility and purpose of the measures are discussed to increase the system security level. Power system security and stability analysis include: power system power flow and static state security analysis, transient stability, dynamic stability, influence of serious faults on system stability,reasonable operation schemes and control measures of UHVAC, as well as influence between UHVAC and UHVDC transmission system and system security on both sides, reactive power balance and voltage regulation, short-circuit current, the advanced technology to improve the stability performance and the transmission efficiency of UHV grid, etc.
