Abstract

In this paper we propose an improved PV generation systems. Improved systems for temperature and humidity controlled heating and air conditioning offers a pleasant environment within the building, set up chopper and consists of a PWM voltage type inverter. The proposed system is stable modulation for a one-chip microprocessor using the synchronous signal and control signals was treated. The proposed system is a PWM voltage type inverter and phase of the synchronous to the grid voltage to detect the system voltage and inverter output to drive the statue, so surplus power to connection was able to, certain buildings such as buildings or hospitals, temperature and humidity sensor is applied to the good dynamic characteristic could be obtained. In addition, the system was applied to the high power factor and low-frequency harmonics by maintaining the output load and grid to power to be supplied to a stable control could get a good result.

본 논문에서는 온도와 습도 및 냉 난방을 조절하여 건물 내의 쾌적한 환경을 제공하기 위한 승압쵸퍼와 PWM 전압형 인버터로 구성된 태양광 발전 시스템을 제안하였다. 이 시스템은 안정된 변조를 위해 원칩 마이크로프로세서를 사용하여 동기신호와 제어신호로 처리하였다. PWM 전압형 인버터와 위상의 동기를 위하여 계통전압을 검출하여 계통전압과 인버터 출력을 동상 운전하므로 잉여전력을 연계할 수 있게 하였으며, 건물이나 병원 등 특정 건물의 온도 및 습도센서에 적용하여 양호한 동특성을 얻을 수 있었다. 또한 시스템에 적용한 결과 고역률과 저고조파 출력을 유지함으로써 부하와 계통에 전력이 안정하게 공급될 수 있도록 제어하여 좋은 결과를 얻을 수 있었다.
