초록

본 논문에서는 태양광과 풍력을 조합한 하이브리드 발전시스템을 이용하여 승압 쵸퍼와 PWM (pulse width modulation) 전압형 인버터인 전력변환기로 구성하였고, 또한 PWM 전압형 인버터는 태양전지가 연속 발전할 수 없는 단점을 보완하기 위해 일반 상용전원과 연계하고 에너지저장장치 (ESS; energy storage system)를 상시 운영하여 공항의 기상 변화에 따른 파장별 LED 항공 유도등을 효율적으로 운용하는 시스템을 구성 하였다. 태양전지에 대한 특성 해석과 수학적 모델링을 통한 시뮬레이션을 행하여 태양전지 특성 사양과 비교하였고, PWM 전압형 인버터와 위상동기를 위해서 계통전압을 검출하여 계통전압과 인버터 출력을 동상 운전하므로 잉여전력을 계통과 연계할 수 있게 하였으며 공항의 활주로, 항공 유도등에 적용하여 양호한 동특성을 얻을 수 있는 제어회로를 동시에 개발하여 항공유도등의 다양성을 추구할 수 있음을 확인 하였다.

In this study, the system was composed of the booster chopper and the power converter, which is a pulse width modulation (PWM) voltage inverter using a hybrid power generation system solar cell energy and wind force, Furthermore, in order to compensate the PWM voltage type inverter was linked with the general commercial power source, and through a normal operation of energy storage system (ESS), the system operated the LED Taxi Light by Wavelength according to Meteorological Changes at the airport in an efficient manner. The performance of the system was compared with the solar cell characteristics specification. In addition, for phase synchronization with the PWM voltage type inverter, the grid voltage was detected so as to operate the grid voltage and inverter output in the same phase and to connect the surplus electric power with the system. Finally, by developing a control circuit at the same time from which an excellent dynamic characteristics can be obtained through applying to the airport runway taxi light, it was concluded that a variety of taxi light can be pursued.
