[Applications] power_PVarray_3500W_me DL : 0: The SPS PV array model implements a PV array built of series- and parallel-connected PV modules. It allows modeling a variety of preset PV modules available from NREL System Advisor Model (Jan. 2014) as well as a user-defined PV module. The PV array block has two inputs that allow you to supply varying sun irradiance (input Ir in W/m^2) and temperature (input T in deg. C) data. In our example, the PV array consists of one string of 14 Trina Solar TSM-250 modules connected in series. At 25 deg. C and with a solar irradiance of 1000 W/m2, the string can produce 3500 W. Two small capacitors, connected on the + and - terminals of the PV array, are used to model the parasitic capacitance between the PV modules and the ground.

[Applications] Keltner_Channel DL : 1: 由Chester W. Keltner于1960年创建的一种经典的技术分析指标。该指标在某种程度上与布林带和轨道线指标类似。该指标使用三根线：中线是使用10日简单移动平均线来表示典型的价格，上线和下线分别由加上或者减去距离中线的日价格范围移动平均数值（高位和低位的差值）组成。这样，就创建了一个基于波动范围的通道。您可以修改该指标这种版本移动平均线的所有参数。该指标适用于MT4(A classic technical analysis index created by Chester W. Keltner in 1960. To some extent, the index is similar to that of the brin and orbitals. The index uses three lines: the median line is the 10 day simple moving average line to represent the typical price, and the online and offline lines are composed of the moving average value of the daily price range plus or minus the distance from the middle line (the difference between high and low position). In this way, a wave - based channel is created. You can modify all the parameters of this version of this version of the moving average line. The index is suitable for MT4)
