摘要：
Based on linear active disturbance rejection control (LADRC), a controller for variable speed wind generator (VSWT) is proposed to improve the transient stability of the power system. According to the controllability of wind farm on synchronous generators, some of synchronous generators are divided into the wind farm equivalent controllable generator group (WFECGG), and WFECGG is transformed into a wind farm equivalent controlled system (WFECS). Then, based on the model of WFECS, a wind farm controller is designed based on LADRC. Due to the real-time estimation and compensation of the perturbation, the controller does not need the exact model information of the synchronous generator and VSWT, and meanwhile it has good adaptability to the variation of operation mode. The controller has the character of decentralized coordination without wind farm center coordination. The simulation cases carried on the modified IEEE 10-generator 39-bus system verify the effectiveness of the proposed controller on enhancing the synchronous stability, and meanwhile it has the good adaptability to the variation of system operation mode. © 2016, High Voltage Engineering Editorial Department of CEPRI.
