Description

電力供應系統Power supply system

本發明係與供電系統有關；特別是指一種可作直流與交流轉換的電力供應系統。The invention relates to a power supply system; in particular, it refers to a power supply system that can convert between DC and AC.

由於節能減碳與環保問題受到關注，世界各國致力於發展對環境有益之綠能發電，綠能發電的問題是於如何將發電得到之電力儲存。此外，一般發電廠在用戶用電集中的尖峰時段，亦會增加發電機組的發電量，而在離峰時段則是減少發電量。然，離峰時段的電力亦無法保留到尖峰時段使用，時常導致發電廠在尖峰時段的發電量不足，需要更多的發電機組因應尖峰時段的發電量。As energy-saving, carbon-reduction and environmental protection issues have attracted attention, countries around the world are committed to the development of green power generation that is beneficial to the environment. The problem of green power generation is how to store the electricity obtained from power generation. In addition, general power plants will also increase the power generation capacity of the generating units during peak periods when user power is concentrated, while reducing power generation during off-peak periods. Of course, the off-peak power cannot be reserved for use during peak periods, which often results in insufficient power generation during peak periods, and more generator sets are required to respond to peak periods.

為此，坊間已有開發出一種供電系統，能將電廠或綠能發電設備的電力儲存於電池，並且能將所電池儲存的直流之電能轉換為交流電輸出給負載使用。To this end, a power supply system has been developed in the market, which can store the power of the power plant or green energy power generation equipment in the battery, and can convert the stored DC power of the battery into AC power and output it to the load.

圖１所示為習用的供電系統1，包含一儲能裝置10與一電力轉換裝置20，該儲能裝置10包括一第一機殼12、複數個蓄電池14、一正極16與一負極18，該第一機殼12為金屬材質，該些蓄電池14位於該第一機殼12中且電性連接該正極16與該負極18。該電力轉換裝置20包括一第二機殼22與一轉換模組24，第二機殼22為金屬材質且電性連接該第一機殼12以形成共地，該轉換模組24設置於第二機殼22中，轉換模組24電性連接該儲能裝置10的正極16與負極18，轉換模組24電性連接交流電源100與負載200，轉換模組24用以進行交流電與直流電之間的轉換，以對儲能裝置的蓄電池14充電，或將來自儲能裝置10的直流電轉換為交流電供電給負載200。Figure 1 shows a conventional power supply system 1, which includes an energy storage device 10 and a power conversion device 20.

It can be used to charge the battery 14 of the energy storage device, or convert the direct current from the energy storage device 10 into alternating current to supply power to the load 200.

由於轉換模組24在進電力轉換時會產生雜訊，所產生的雜訊將會經由第二機殼22傳遞至儲能裝置10以及經由轉換模組24傳至正極16與負極18，如此，將會造成儲能裝置10內部的電壓偵測元件、電流偵測元件、或溫度偵測元件受到干擾而影響偵測結果，造成偵測失準。Since the conversion module 24 generates noise during power conversion, the generated noise will be transmitted to the energy storage device 10 through the second casing 22 and to the positive electrode 16 and the negative electrode 18 through the conversion module 24. In this way, This will cause the voltage detection element, current detection element, or temperature detection element inside the energy storage device 10 to be interfered and affect the detection result, resulting in inaccurate detection.

此外，由於儲能裝置10會透過通訊界面300與電源管理裝置400通訊，因此，儲能裝置10在通訊界面300上傳遞的電訊號亦會受到轉換模組24產生的雜訊干擾而發生錯誤。In addition, since the energy storage device 10 communicates with the power management device 400 through the communication interface 300, the electrical signal transmitted by the energy storage device 10 on the communication interface 300 will also be interfered by the noise generated by the conversion module 24 and cause errors.
