OPTIMAL EXCITATION CONTROL SIMPLIFIED IN MEASUREMENT CHANNELS

Combining conventional optimal excitation control with the characteristics of PID excitation regulator and power system stabilizer, this paper presents a new design method for optimal excitation control. In the design method, the partial measurable variables of transmission system and their differential variables compose a set of state feedback variables, so the measurement channels of the excitation control are simplified. The math model of the control system is established. The static stability, transient stability and dynamic characteristics of the control system are calculated. The results show that the control is superior to the conventional optimal excitation control in capability. In addition, as the control's measurement channels are simplified, it can be taken into practice in engineering more easily.
