Abstract EN
The wind-thermal hybrid power transmission will someday be the main form of transmitting wind power in China but such transmission mode is poor in system stability.
In this paper, a coordinated stability control strategy is proposed to improve the system stability.
Firstly, the mathematical model of doubly fed wind farms and DC power transmission system is established.
The rapid power controllability of large-scale wind farms is discussed based on DFIG model and wide-field optical fiber delay feature.
Secondly, low frequency oscillation and power-angle stability are analyzed and discussed under the hybrid transmission mode of a conventional power plant with wind farms.
A coordinated control strategy for the wind-thermal hybrid AC/DC power system is proposed and an experimental prototype is made.
Finally, real time simulation modeling is set up through Real Time Digital Simulator (RTDS), including wind power system and synchronous generator system and DC power transmission system.
The experimental prototype is connected with RTDS for joint debugging.
Joint debugging result shows that, under the coordinated control strategy, the experimental prototype is conductive to enhance the grid damping and effectively prevents the grid from occurring low frequency oscillation.
It can also increase the transient power-angle stability of a power system.
