Thus the reactive compensator can be located in the center of the distributed load in the area and make the best user of the compensator ' s capacity . the distance flowed by the reactive current is efficiently reduced and the active loss of power net goes down . two - stage control model is adopted in the optimized control technique of the system 該系統(tǒng)采用了測(cè)量點(diǎn)與補(bǔ)償點(diǎn)與分開(kāi)的方式,實(shí)現(xiàn)了區(qū)域性無(wú)功負(fù)荷監(jiān)視,使無(wú)功補(bǔ)償點(diǎn)可以安置在區(qū)域性分散負(fù)荷的中心部位,最大程度地利用了補(bǔ)償容量,有效地縮短了無(wú)功電流傳輸?shù)木嚯x,降低了電網(wǎng)的有功損耗。
The rule for the determination of the optimal installation places is put forward with the consideration of reactive load changes . the method for reactive power optimal compensation based on the optimal incremental active loss is investigated in details . the impact of reactive power compensation on network voltages is discussed in the following 在無(wú)功優(yōu)化方面,探討了無(wú)功補(bǔ)償裝置的最佳安裝地點(diǎn),并給出了無(wú)功負(fù)荷變動(dòng)情況下無(wú)功補(bǔ)償裝置最佳安裝地點(diǎn)的選擇原則,深入分析了按無(wú)功經(jīng)濟(jì)當(dāng)量的無(wú)功最優(yōu)補(bǔ)償方法以及補(bǔ)償對(duì)配電網(wǎng)電壓的影響。
Then reactive power optimizing calculation is figured out on the chongqing power network on condition that the loss minimum of the active power network is object function , taking account of the limit of voltage restriction condition , adopting three mode of generators adjustment reactive power compensation and tap change . it achieves satisfaction result , expectable purposes of reducing voltage and active loss 然后以系統(tǒng)有功網(wǎng)損最小為目標(biāo),考慮電壓約束條件的限制,采用發(fā)電機(jī)調(diào)節(jié)、無(wú)功補(bǔ)償、分接頭調(diào)整三種調(diào)控方式對(duì)重慶電網(wǎng)低谷時(shí)段的運(yùn)行方式進(jìn)行了無(wú)功優(yōu)化計(jì)算和分析,取得了滿意的結(jié)果,達(dá)到了預(yù)期的降壓目的,減少了網(wǎng)損。
