The Future

With the continuous construction of ultra high voltage (UHV) power grid, East China-Central China North China will be interconnected via UHV lines to be a UHV synchronous grid in the future. Further expansion of the grid scale, the existing active power and frequency control mode has been unable to adapt to the new features. Based on the future structure of North China-Central China-East China synchronized power grid, the article built the whole network of the AGC control model using PSD-FDS full dynamic simulation program. By the simulation of examples, the problems of AGC control mode for UHV synchronous power grid has been pointed out visually. Finally, the paper presented an ideal AGC control mode called centralized control mode to deal with the new challenge.

This paper analysis the characteristics of two-machine equivalent system in out of step state. According to variation in the out of step state, study the out of step criterion of .Use change area to determine whether the system is out of step, The criterion is simple and clear, and the concept is clear. It can distinguish the acceleration step and deceleration of step, and automatically adapt to system changes in the structure and Operation mode. The minimum voltage amplitude of the device installed is used for capture the oscillation center .The 2012 East China Power Grid, region A fleet out of step mode is simulated analyzed, It is verify that the criterion of accuracy and adaptability in the East China Power Grid.
