Reactive Power

Reactive power is specified separately from the active power and may be specified as

either fixed kvar values or a fixed power factor value. If the PF property is specified, the

model holds a constant output power factor until the PF property is changed (default

mode). If the kvar property is specified, the inverter is assumed to attempt to hold that

value despite the present value of the panel power. The actual kvar output is dropped if

the rated kVA of the inverter is exceeded.

These are the only two reactive power modes currently implemented in the present

version. Many of the larger PV system inverters can also adjust vars to regulate voltage.

Therefore, future versions may have voltage regulation modeling capability. (That

capability is nominally in the generic Generator object - model=3).

Loadshapes and Tshapes

For Daily, Yearly, and Duty-cycle simulations, the Irradiance and temperature, T, base

values can be modified by Loadshape and Tshape objects, respectively, corresponding to

the type of simulation being performed. This is what enables the model to provide a

varying power input for the sequential time simulations.

Both the Yearly and Duty-cycle shapes default to the shape defined for the Daily shape if

they are not specified. If the Daily shape is not defined, it defaults to a constant multiplier

of 1.0.

    無功功率

    無功功率從有功功率單獨指定,並且可以指定為

    任一固定的千乏值或固定的功率因素值。如果指定了PF屬性,則

    模型保持一個恆定的輸出功率因數直到PF​​屬性被改變(缺省

    模式)。如果指定了千乏屬性,逆變器被假定為試圖保持該

    值,儘管面板的電力的當前值。如果實際千乏輸出下降

    逆變器的額定千伏安已過。

    這些是目前在本實施的僅有的兩個功功率模式

    版本。許多規模較大的光伏系統逆變器還可以調整瓦爾來調節電壓。

    因此,未來的版本可能有電壓調節建模能力。 (這

    能力名義上是在通用發電機對象 - 模型= 3)。

    Loadshapes和Tshapes

    對於每天,每年,和佔空比模擬,輻照度和溫度,T,基地

    值可以通過Loadshape進行修改和T形,對象,分別對應於

    正在執行的仿真的類型。這是使該模型,以提供一個

    不同的電源輸入為連續時間模擬。

    無論是年度和佔空比形狀默認為每日形若定義形狀

    它們不指定。如果每日形狀沒有定義,則默認為一個常數倍增

    1.0。
