电力系统电压逆调整
reversing adjustment of electric power sys-tem voltage
-.，~、，。叼，lyu 1lltlOOZneng电力系统电压逆调井(reversing adjustmentof electrie卯wer system volta罗)按规定的运行电压允许偏差，在电力系统高峰负荷时期将电压中枢点的电压调整到电压曲线(见电压中枢点)上限，在低谷负荷时期将电压调整到电压曲线下限的电压调整方法。 电力系统在高峰负荷时，输电线和变压器的传输功率大，它们的电压损耗也大，用户处的电压偏低;在低谷负荷时，输电线和变压器的传输功率小，它们的电压损耗也减小，用户处的电压偏高。为了保持较好的供电电压质量、减小用户处的电压变化幅度，要求电力系统实行逆调压。电力系统实现逆调压应具备的一些条件:①要有合理的电网结构，尤其是供电网和配电网要根据负荷密度确定合理的供电半径;②要有充足的、布局合理的无功电源;③要有足够容量的能进行双向调节(既能发出无功功率，又能吸收无功功率)的无功补偿装置.如调相机、装有并联电抗器的电容器组、静止无功补偿器等;④运行中灵活调节电压幅值和相角的设备，如带负荷调压变压器、移相变压器等;⑤配电网中装设可投切的电抗器。
