Description

technical field [0001] The present invention relates to an RTDS-based reactive voltage control efficiency detection method for regional power grid automatic voltage control systems, in particular to a method for building an RTDS-based AVC soft simulation closed-loop system platform and using the reactive voltage of the closed-loop system platform Control efficiency detection method. Background technique [0002] Over the past ten years, voltage stability has increasingly become the focus of power system attention. In the modern power grid, due to the heavier load of the weak system and long lines, the transmission capacity of the power grid is getting closer and closer to its limit, which makes the problem of voltage stability more prominent. Some large power grid accidents are also mainly caused by voltage instability. Studies have shown that there are many reasons for voltage instability: load increase, generator or line failure, system reactive power shortage, on-load t...
