摘 要:采用局部參數(shù)化的連續(xù)潮流法和分岔理論,研究了靜止無功補償器(SVC)在交直流互聯(lián)系統(tǒng)中的最優(yōu)安裝位置。以WSCC9節(jié)點測試系統(tǒng)為例,通過追蹤系統(tǒng)的平衡解流行曲線和搜索系統(tǒng)穩(wěn)定極限的分岔點,得出系統(tǒng)中對無功不足比較敏感的母線,并通過在某一母線節(jié)點處添加SVC提高整個交直流系統(tǒng)電壓穩(wěn)定性,實現(xiàn)了在最經(jīng)濟情況下使系統(tǒng)的無功功率得到補償?shù)哪康摹?br />

Abstract: Adopting local parameterized continuous trend method and bifurcation theory, this paper studied the optimal installation location of static var compensator (SVC) in AC/DC interconnected system. Taking the WSCC9 node test system for example, by tracking the epidemic curve of the system equilibrium solution and searching the bifurcation point of system stability limit, the more sensitive bus to insufficient reactive power compensation was obtained in the system. And the voltage stability of the whole AC/DC system at a bus node was improved to realize the compensation of the system reactive power in the most economic situation.
Key words: static var compensator; voltage stability; continuous trend method; bifurcation theory; installation position
