描述
根據(jù)上文對10kV配電線高壓與低壓問題的分析,可以知道造成高電壓和低電壓問題的根本因素是電壓調(diào)節(jié)因素,因此,供電部門往往會采用以往的經(jīng)驗(yàn)進(jìn)行電壓調(diào)節(jié),例如:并聯(lián)配電線網(wǎng)整體電容和電壓調(diào)節(jié)器,進(jìn)而控制配電線網(wǎng)電壓范圍,再者就是并聯(lián)電抗器和電壓調(diào)節(jié)器,同樣也能控制配電線網(wǎng)電壓范圍。雖然采用以往經(jīng)驗(yàn)也能有效的解決10kV配電線高壓與低壓問題,但在實(shí)際建設(shè)和操作中存在著眾多問題,以文中并聯(lián)電抗器和電壓調(diào)節(jié)器為例子,首先電壓調(diào)節(jié)器的頻繁使用會對配電線網(wǎng)造成一定的損傷,而且在一定情況下,電壓調(diào)節(jié)器不僅不能使用還會阻礙電抗器的正常使用,進(jìn)而造成配電線網(wǎng)長時間處于超負(fù)荷狀態(tài),進(jìn)而增加高電壓和低電壓問題出現(xiàn)的頻率。因此,為確保配電線網(wǎng)的正常運(yùn)行,一般供電部門用串聯(lián)補(bǔ)償技術(shù)代替一般的電壓調(diào)節(jié)措施。
