| Abstract: | Research on coordinated voltage control in the UHV demonstration project is presented. To simulate the quasi-steady process of reactive power and voltage regulating, a power-flow-based simulation platform is developed, and it takes both operation constraints on security and insulation requirement of UHV transmission lines into consideration. The two modes of independent control and coordinated control are compared in this paper. The voltage regulating process of the power grids in Three Gorges area and its neighboring area is simulated, including generator under-excitation operation, HVDC reduced voltage operation and 500 kV transmission lines outage. Based on the simulation results, the key factors influencing voltage regulating for south terminal substations of the UHV demonstration project are pointed out. |
