摘要

光伏发电系统作为清洁能源,取代化石燃料,具有广阔的发展前景。化石燃料存在废气排放或空气污染等诸多环境问题。在公用事业交互式光伏发电系统中,光伏阵列与公用事业之间的连接采用三相逆变器。本文采用dq变换,设计了一种由电流控制器、电压控制器、锁相环控制系统和交互电压鉴相器组成的光伏发电系统三相逆变器。该逆变器系统为国内负荷和公用线路提供了统一功率因数的正弦交流电流。

The power factor control system of photovoltaic power generation system
The photovoltaic power generation system has a great future as clean energy instead of fossil fuel, which has many environmental problems such as exhausted gas or air pollution. In a utility interactive photovoltaic generation system, a three phase inverter is used for the connection between the photovoltaic array and the utility. This paper presents a three phase inverter for photovoltaic power system with current controller, voltage controller, PLL control system and the phase detector of interactive voltage by using dq transformation. The proposed inverter system provides a sinusoidal AC current for domestic loads and the utility line with unity power factor.
