Description

再生能源供電系統Renewable energy power supply system

本發明係與交流電力系統有關;特別是指一種可抑制二倍頻漣波的再生能源供電系統。 The invention relates to an AC power system; in particular, it relates to a renewable energy power supply system capable of suppressing double-frequency ripples.

已知單相之交流電力系統被廣泛運用於低功率之應用上,一般單相之交流電力系統係採用一直流-交流轉換器(DC-AC),將直流電轉換成單相的交流電輸出。 It is known that single-phase AC power systems are widely used in low-power applications. Generally, single-phase AC power systems use a DC-AC converter to convert DC power to single-phase AC power output.

直流-交流轉換器(DC-AC)在輸出側產生之二倍頻瞬時功率時,會因能量守恆定律(Law of Conservation of Energy)反映至輸入側而形成二倍頻漣波功率(Ripple Power at Twice The Grid Frequency),而影響交流電力系統的性能。舉例而言,對於應用單相交流電力之太陽能供電系統,此二倍頻漣波功率將會造成最大功率點追蹤(Maximum Power Point Tracking)產生浮動,進而降低太陽能供電系統的性能。 When the DC-AC converter generates instantaneous double-frequency power at the double frequency, the law of conservation of energy (Law of Conservation of Energy) is reflected to the input side to form a double-frequency ripple power (Ripple Power at Twice The Grid Frequency), which affects the performance of AC power systems. For example, for a solar power system using single-phase AC power, this double-frequency ripple power will cause the Maximum Power Point Tracking to fluctuate, thereby reducing the performance of the solar power system.

為減少二倍頻漣波,傳統之解決方案為放置具有大電容值的電解電容(Electrolytic Capacitor)在輸入側,以吸收二倍頻漣波功率與高頻雜訊,然而,大電容值的電解電容伴隨而來的是其大體積與電容壽命的問題,導致交流電力系統的可靠度下降。 In order to reduce the double-frequency ripple, the traditional solution is to place an electrolytic capacitor with a large capacitance value on the input side to absorb the double-frequency ripple power and high-frequency noise. However, the large-capacity electrolytic capacitor Capacitors are accompanied by problems of their large size and longevity of the capacitors, leading to a decrease in the reliability of the AC power system.

有鑑於此,本發明之目的在於提供一種再生能源供電系統,可減少二倍頻漣波,提升供電系統的性能。 In view of this, the object of the present invention is to provide a renewable energy power supply system, which can reduce double frequency ripples and improve the performance of the power supply system.
