模拟新能源(風能,太陽能,地熱能等)

第一, Matlab simulation模拟新能源(風能,太陽能,地熱能等)

這個要求已完成,主要研究了風能,光伏。

結構分别如下所示:

模拟新能源(風能,太陽能,地熱能等)
模拟新能源(風能,太陽能,地熱能等)

第二,出圖有關電壓,電流,電阻,以及功率輸出等的關系圖,并且能用matlab code或者在模拟中進行計算材料成本,排放,效率,并且能夠有互相的可比性,比如,輸出功率統一設定為10MW然後觀察每個裝置的效率以及損耗,并且建造的成本,運作時的排放污染等。第三,最好能出柱狀圖,餅圖,線形圖以及資料表格予以說明。

因為功率輸出P=U*I,這裡是基于這個公式計算的功率,是以給出每個圖的U,I,P關系圖。

這裡設定單個裝置的功率為6.2kw。這裡以單個風力發電功率為基準。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

風電功率分别為:

模拟新能源(風能,太陽能,地熱能等)
模拟新能源(風能,太陽能,地熱能等)

由于單塊的光伏發電闆發電量都比較小,這裡需要獲得相同功率的光伏輸出,那麼則需要

6200/169 = 37個光伏發電闆。

是以,下面分析發電成本和污染以及裝置的損耗,都以這個倍數為基準進行對比。

模拟新能源(風能,太陽能,地熱能等)

這裡比例,也符合一些文獻的資訊,比如如下網站:

模拟新能源(風能,太陽能,地熱能等)

即光伏發電成本略高于風能發電的結果。

下面對污染進行簡要的分析。污染問題,這裡我們主要針對污染因素對環境造成的影響而導緻的環境治理費用進行對比,

因為風能污染主要是噪聲等污染

光伏,則主要是光污染,以及蓄電池污染等,

他們污染類型不一樣,是以統一轉換為需要治理這些污染所投入的成本的對比。

模拟新能源(風能,太陽能,地熱能等)

通過分析可知,風能發電的噪聲污染治理成本價較高。

不過這裡有一個問題需要注意,就是光伏發電需要投入大量的蓄電池,而這些電池在使用壽命達到之後,如果處理不合适,将大大增加環境污染,這裡仿真不考慮這個因素。

第四,需要有相對應的設計說明,以及使用了哪些方法進行論證,哪些是不可控因素,哪些是變量,具體模拟時參數的調整,如何控制變量和不可控因素,并且指出最可靠的計算方式和模拟方式,然後再加以讨論

每個電路的涉及到的電路模型和相關理論,在單獨的設計說明文檔中已經有了說明了。以及相關公式也做了描述。

第五,最後,做一下讨論,關于life cycle assessment,這些實驗的方法和資料是否有差錯,是否有可修改的地方,這些資料和結果是否是我們理想的資料和結果,如何判定他是可靠的資料和結果。

關于風力發電,其壽命主要取決于風電機組主軸軸承的壽命,這是由于這個逐漸是風力發電中壽命最短的一個部件,根據前面的仿真可知,

模拟新能源(風能,太陽能,地熱能等)

而這裡的功率和主軸軸承的轉速成正比,

其關系滿足如下關系式:

模拟新能源(風能,太陽能,地熱能等)

這裡使用壽命函數和轉速之間滿足如下式子:

其中N為主軸軸承的循環次數。在較好的工況下,其循環次數為9.49*10^8(這個是實驗資料,非仿真資料)随着工況變差, N取值逐漸降低

這裡分析如下幾種類型的工況

N1=9.49*10^8;

N2=7.71*10^8;

N3=6.23*10^8;

N4=4.23*10^8;

N5=2.81*10^8;

N6=1.11*10^8;

模拟新能源(風能,太陽能,地熱能等)

而光伏發電,其主要壽命由蓄電池決定。一般情況下,蓄電池的充放電會逐漸降低可持續充電能力,下面給出了蓄電池的充放電衰減變換情況。
