초록

발전기의 전압조정장치(AVR)를 이용하여 전압을 조절하는 방식은 기존 아날로그방식과 교체중인 디지털방식을 나눌 수 있다. 일반적으로 브러쉬레스형의 여자시스템을 이용하여 전압을 조절할 경우 전부하에 대하여 전압변동을 작게 하여야 한다. AVR의 제어방법으로 PID(비례-적분-미분)제어방식이 많이 사용되고 있다. 그러나 이 제어기법은 제어대상에 대하여 제어기의 파라미터를 조절하여 과도응답을 줄이고 있다. 따라서 제어대상이 달라질 경우 다시 제어기의 파라미터를 다시 설정해야하는 문제점이 있다. 본 연구에서는 제어대상의 파라미터 변동에 대하여 제어기의 파라미터를 재설정 필요없이 iPID(intelligent PID)제어기를 이용하여 발전기 AVR시스템에 적용하여 전부하 시에도 전압변동이 작은 응답을 얻도록 설계하고 시뮬레이션과 실험을 통하여 과도응답을 개선하였다.

Method for regulating voltage using a generator voltage regulating device (AVR) is divided in an existing analog system and a digital replacement. Typically, to adjust the voltage by using a brushless excitation system of the type to be reduced for a voltage change under all. The control method of the AVR as a PID (proportional-integral-differential) control method is widely used. However, the control scheme is to reduce the transient response of the control parameters of the controller to the control object. Therefore, if the control target should change, there is a problem, reset the parameters of the controller again. In this study, without having to reset the parameters of the controller for the parameter variations to be controlled iPID (intelligent PID) using a controller designed to obtain a generator AVR system voltage variation is small in response to full load is applied to and through simulations and experiments improved transient response.
