相间功率控制器相间功率控制器interphase power controller, IPCx旧ngJlon gongIU kongzh一q-相间功率控制器(interphase power“on-troller,IPC)不同相位的电源分别经过申联电感和电容器组向翰电线受端供电的有功功率控制装t.为了产生相位移以控制功率,总是将一端(如送端)的某相与另一端(如受端)的其他两相通过电感或电容相连,因此称之为“相间功率控制器”,实际上控制的仍是线路的有功功率。在移相的相位和串联的电感电容值确定后,相间功率控制器输送的有功功率将保持近于恒定,对功角的变动相对不敏感。装!原理IPC的基本原理图如图1所示。图l 图1 IPC墓本原理图后的接电容器。中仍和舜表示两组电力移相器相应的移相角,它可以由三相变压器的不同接线方式移相,其超前相移的接电抗器,滞一种经济实用的移相方法是利用三相中其它两相或它们的负值作为本相的移相电源,例如用B、C相作为A相的移相电派(如图2所示),或一C、一B作为A相的移相电源(如图3所示).用B、C相作为A相┌─┐│ ├─┐│ │口│└─┴─┘图2 IPC一240的相I图和三相电路图(a)相t圈.(b)电路图的移相电源时,C相比A相超前1200,B相比A相滞后1200,总共相移是240。,因此称这种电路为IPC-240,受端A相电流分别来自于UBs的IBc和Ucs的IcL。电感电流超前受端A相电压600,电容电流滞后A相电压600。┌─┐│二│└─┘图3 IPC一12。的相t图和三相电路圈(a)相t图,(b)电路图另一种利用一右。和一亡C电压作为A相移相电源。一亡。超前亡*600,一亡。滞后亡人600,电压移相共1200,因此称为IPC一120。图3中,IPC一120的移相是由Y一Y一。接线变压器构成,其电容电流与电感电流与j人仅各差300.IPC一240与IPc一120相比,前者需要较大的L、C容量,功率因数低,效率也低,而后者较优越.从图1可知,可以有很多移相方式,它们的特点各不同,但墓本特性与上述两种近似。主要特点①有功功率的传输近于恒定,在送受端功角差为土250范围内有功功率只有不到10%的变化。如图4所示,当IPC一120的翰出电压UA,向超前移250成为创A,,超前的电感电流IcL因U队缩小到口队而减少到rCL(电流IcL与U队成正比)。电容电压Uc^增大到U‘。‘,IBc也成比例增大到rBc.r‘与U‘。‘、尸cL与U‘B^仍保持垂直。rBc与I’cL的相t和r人仍与原A相电流I、的幅值和相位相同。而移相后与电压口人r同相的电流有功分量尸P只比原来减少9.4%(二l一cos25“),即有功功率只变化9.4肠。同时它需要补充无功电流r,,事实上,功角a变动后,保持有功功率恒定的必要条件是补充所需的无功电流尸r。
