【摘要】：按負荷和電網(wǎng)無功電壓特性對高壓配電網(wǎng)進行分類,針對不同類型采取差異化的無功補償配置方案.以含小水電高壓配電網(wǎng)為對象,提出綜合考慮容/感性無功補償配置的無功優(yōu)化規(guī)劃模型,以滿足含小水電高壓配電網(wǎng)不同的無功電壓調(diào)控需求;運用"無功配置率"指標指導(dǎo)不同類型變電站無功補償配置量的選擇,并對該類配電網(wǎng)的容/感性無功配置原則進行了優(yōu)化和細化.實例分析表明,按此原則來指導(dǎo)含小水電高壓配電網(wǎng)的無功配置,可提高該類配電網(wǎng)電壓調(diào)控和無功平衡能力,有助于降低網(wǎng)損,避免容性無功補償過量配置導(dǎo)致的投資浪費.利用該方法,得出4種不同類型的高壓配電網(wǎng)的無功配置率推薦范圍,可作為高壓配電網(wǎng)無功補償配置的細化原則.
[Abstract]:The high voltage distribution network is classified according to load and reactive power and voltage characteristics, and different reactive power compensation schemes are adopted for different types. Taking the high-voltage distribution network with small hydropower as the object, a reactive power optimal planning model considering capacitive / inductive reactive power compensation configuration is proposed to meet the different reactive power and voltage regulation needs of the high-voltage distribution network with small hydropower. The reactive power allocation rate is used to guide the selection of reactive power compensation configuration in different substations, and the capacitive / inductive reactive power allocation principle of this kind of distribution network is optimized and refined. The analysis of examples shows that according to this principle to guide the reactive power allocation of high-voltage distribution network with small hydropower can improve the capacity of voltage regulation and reactive power balance of this kind of distribution network, help to reduce the network loss and avoid the investment waste caused by capacitive reactive power compensation overallocation. By using this method, the recommended range of reactive power allocation rate for four different types of high-voltage distribution networks is obtained, which can be used as a detailed principle for reactive power compensation allocation in high-voltage distribution networks.
