| 自(zi)3月份以(yi)來，寧夏(xia)風電(dian)發電(dian)量(liang)屢創新高。3月18日，風電(dian)發電(dian)量(liang)達4198萬千(qian)(qian)(qian)瓦(wa)時，占(zhan)(zhan)當日總(zong)用電(dian)量(liang)的20%。截止目前，寧夏(xia)電(dian)網并(bing)網風電(dian)容量(liang)279萬千(qian)(qian)(qian)瓦(wa)，光伏容量(liang)58萬千(qian)(qian)(qian)瓦(wa)，新能(neng)源總(zong)裝機容量(liang)達到337萬千(qian)(qian)(qian)瓦(wa)，占(zhan)(zhan)全(quan)網總(zong)裝機的17%。 隨(sui)著新(xin)能(neng)源電(dian)力(li)規模(mo)化迅猛發展(zhan)以及占電(dian)網(wang)(wang)負荷(he)和(he)用電(dian)比重的不斷增(zeng)加(jia)，受網(wang)(wang)架結構、系統(tong)調峰、電(dian)壓穩(wen)定等因素制約，電(dian)網(wang)(wang)安(an)全與(yu)新(xin)能(neng)源消(xiao)納壓力(li)俱增(zeng)，并(bing)由局部性(xing)、時段性(xing)問題轉化為全局性(xing)、經常(chang)性(xing)問題。電(dian)網(wang)(wang)運(yun)(yun)行中多處新(xin)能(neng)源集中送(song)出通道存在正(zheng)常(chang)運(yun)(yun)行狀況下設備過載問題，超出了電(dian)網(wang)(wang)安(an)全穩(wen)定運(yun)(yun)行的第一級標準。
