Description
technical field [0001] The invention relates to the technical field of AC and DC power grids, in particular to a display system and display method of AC and DC power grid operation characteristics based on RTDS real-time digital simulation. Background technique [0002] With the wide application of high-power power electronic technologies such as HVDC, series compensation, SVC, and STATCOM, and the gradual promotion of clean energy such as wind power generation and energy storage, the operating characteristics of the power grid have become more complex. Accidents will also be more diverse, and the control characteristics of large units, large-capacity HVDC and FACTS units in the network are critical to accident recovery. [0003] The security and stability of large-scale systems are prominent, and the requirements for the professional quality and operating experience of dispatchers, operation and maintenance personnel are also higher and higher. The traditional static safet...
