Power system stability can be improved by proper control of the excitation and governor systems. A stabilizer using multivariable control techniques can be designed to combine and coordinate these two stabilizing contributions. Optimal performance at all operating conditions can be realized by using an adaptive control technique. In this technique the system dynamics for an operating point are identified on line in the calculation of a suitable control. The performance of such a controller was tested on a micro alternator. The prime mover of the micro alternator is a dc machine. This paper describes a method of modeling pre-specified governor-turbine dynamic characteristics on that machine using analog computer techniques. The torque of the dc motor is controlled so that it is proportional to the output of the low power stage by using a PI controller and a voltage chopper. |
