This paper presents an integrated control system for distributed variable speed constant speed （VSCF） wind power unit based on intelligent multi-agents. The control system consists of data capture agent, pitch agent, power curve agent, yaw agent, diagnosis agent, and data transfer agent. The work flows and control algorithms are designed to achieve healthy communications and independent, automatic control among the agents. In addition, a hardware simulation platform is set up and some experiments are carried out. Experimental results show that the control system proposed is effective and promising. It can guarantee the stable operation of the wind power unit, and respond timely and accurately to the faults.
