Description
本發明是有關於一種系統、裝置，及模組，特別是指一種光電管理系統、裝置，及模組。 The present invention relates to a system, device, and module, and more particularly to an optoelectronic management system, device, and module.
隨著人類科技發展的進步，對於用電量的需求逐漸增大，在期望地球的資源能夠永續發展的情況下，綠色能源之一的太陽能在應用上逐漸受到重視。一般用戶會將太陽能轉換成電能的一光電轉換系統電連接到從一變電所輸送電力到每一用戶的一饋線，讓電連接該饋線的多個負載使用該光電轉換系統及該變電所提供的電力。該光電轉換系統包含一太陽能板(PV Panel)，及一換流器(Inverter)。該太陽能板包括複數個依設計進行串聯、並聯的太陽能光電模組。而每一光電模組是由36片或72片的太陽能電池(Solar Cell)串聯組成。則該太陽能板用以將太陽光進行光電轉換，並將轉換的直流電力透過該換流器轉換成交流電力。 With the advancement of human science and technology, the demand for electricity consumption is gradually increasing. Under the expectation that the earth's resources can be continuously developed, solar energy, one of the green energy sources, is gradually gaining importance in application. A photoelectric conversion system that a general user converts solar energy into electrical energy is electrically connected to a feeder that transmits power from a substation to each user, and a plurality of loads electrically connected to the feeder are used to use the photoelectric conversion system and the substation. The power provided. The photoelectric conversion system includes a solar panel (PV Panel) and an inverter (Inverter). The solar panel comprises a plurality of solar photovoltaic modules connected in series and in parallel according to design. Each photovoltaic module is composed of 36 or 72 solar cells connected in series. The solar panel is used to photoelectrically convert sunlight, and convert the converted DC power into AC power through the inverter.
然而，使用該太陽能板進行發電具有以下缺點： However, using this solar panel for power generation has the following disadvantages:
缺點一，不易察覺該太陽能板內的太陽能電池 是否故障，由於該太陽能板是由太陽能電池串聯、並聯組成，當有部分的太陽能電池故障，該太陽能板仍可輸出電壓，讓人不易查覺有任何故障，但是輸出的功率會降低，因而使發電效率下降，進而使售電的價格下降。 Disadvantage 1, it is not easy to detect the solar cells in the solar panel Whether the fault is caused, because the solar panel is composed of solar cells connected in series and in parallel, when some solar cells fail, the solar panel can still output voltage, which makes it difficult to detect any fault, but the output power is reduced, thus making The power generation efficiency has dropped, which in turn has caused the price of electricity to be reduced.
缺點二，該太陽能板的輸出電力的功率不穩定，因為該太陽能板產生光電轉換輸出的電力功率會隨著太陽光而變化，當太陽光沒有被雲遮住時，該太陽能板產生的電力功率大，當太陽光被雲遮住時，該太陽能板產生的電力功率小，因此，當該太陽能板及該變電所供電給該饋線的過程中，可能因該太陽能板本身功率變動率大，讓整個電力系統的電壓不穩定，甚至超過電力公司規定電壓變動率的最大值，則該等負載很容易因而損壞，並造成電力系統供電品質問題。 Disadvantage 2, the power of the output power of the solar panel is unstable because the power of the photoelectric conversion output of the solar panel changes with sunlight, and the power generated by the solar panel when the sunlight is not covered by the cloud Large, when the sunlight is blocked by the cloud, the power generated by the solar panel is small. Therefore, when the solar panel and the substation supply power to the feeder, the power variation rate of the solar panel itself may be large. If the voltage of the entire power system is unstable, even exceeding the maximum value of the voltage variation rate specified by the power company, the loads are easily damaged and cause power supply quality problems.
