光伏发电系统的短路电流计算研究

Research on Short Circuit Current Calculation of PV System

在光伏系统接入报告中,短路电流计算只是给出简单的结果,并未对光伏系统进行具体分析。为此,本文提出了有关短路电流的计算方法,研究其在光伏系统接入报告中的应用。在光伏系统中,短路电流计算可以采用标幺值与有名值相结合的计算方法。通过这两种方法与具体案例,来进一步完善光伏系统接入报告中关于短路电流计算的内容。与普通的光伏系统接入报告对比,加入具体的、准确的短路电流计算,会使一整份光伏系统接入报告显得更加专业且具有竞争性。

In the photovohaic system access report, the short-circuit cun＇ent calculation only gives a simple result, but does not canT on the concrete analysis to the photovoltaic system. Therefore, a calculation method of short circuit current was proposed to study the application of the short circuit current in photovoltaic system access report. In pho- tovoltaic system, the calculation of short circuit current could be done by combining the per unit with the actual val- ue. Through these two methods and concrete cases, the contents of short circuit current calculation in PV system ac- cess report were further improved. Compared with the common PV system access report, adding specific and accurate short-circuit current calculation will make the whole PV system access report more professional and competitive.
