Development and Application of Power System Digital-Analog Hybrid Simulation Technology

With the fast developments of UHV power grid, large-scale AC/DC interconnection causes the profound change of grid characteristic, which puts forward higher requirements for power system simulation. Power system digital-analog hybrid simulation is able to accurately simulate the operation characteristic and dynamic process of AC/DC system, which is the important method to research large-scale AC/DC power grid. Due to the characteristics of high simulation accuracy and high speed, the digital-analog hybrid simulation is a basic platform to acknowledge the operation mechanism of large power grid. But the modeling of hybrid simulation response is relatively complicated, and its scale has certain limitations. The digital-analog hybrid simulation of power system was deeply described in many aspects such as the simulation technology, development and application, etc. And its function and application range were introduced in detail. Finally, combined with the future development needs of UHV large power grid in China, the development direction of the digital-analog hybrid simulation of power system was proposed.
