【摘要】：為探求城市高負(fù)荷密度新區(qū)電壓層級(jí)配置方案的適用性,提出模擬規(guī)劃區(qū)域變電站和電力網(wǎng)絡(luò)綜合規(guī)劃的數(shù)學(xué)模型。采用粒子群算法對(duì)模型進(jìn)行求解,獲得并比較各種負(fù)荷密度和4種設(shè)備選型下,220/110/10 kV、220/110/20 kV、220/20 kV這3種電壓層級(jí)優(yōu)化規(guī)劃方案的建設(shè)規(guī)模及經(jīng)濟(jì)性指標(biāo)。研究表明,負(fù)荷密度達(dá)到10 MW/km2及以上時(shí)宜采用20 kV作為中壓配電電壓;與220/110/20 kV層級(jí)相比,簡(jiǎn)化變電層次的220/20 kV電壓層級(jí)在各種設(shè)備選型下經(jīng)濟(jì)性更優(yōu)。
[Abstract]:In order to explore the applicability of voltage level allocation scheme in urban high load density new area, a mathematical model for comprehensive planning of substation and power network in simulated planning area is proposed. The particle swarm optimization algorithm is used to solve the model, and the load density and four kinds of equipment selection are obtained and compared, 220 鈮，
