Based on the analyses of the classical vector control of doubly fed generators connected to an infinite bus, a excitation control strategy of the power system voltage oriented is presented in this paper. Using with the control strategy, the stator currents, power system voltage and rotor position signals are only required. It is unnecessary to get the precision and real-time and coherence of measurement between the stator and rotor electric values, so that the practical control system of doubly fed generators can be simplified. The steady state regulation characteristics among the stator active power and reactive power as well as the rotor speed, and the transient characteristics of a suddenly three phase shorted circuit of stator terminals to the grand for doubly fed generators are simulated by using this control strategy. It is shown that active power, reactive power and speed are controlled separately and the doubly fed generator appears good in stability and dynamic performances with this control strategy.
