摘要：【中文】本发明公开了一种带有容量补偿功能的可控电抗器装置，包括高压变压器、负载无功调节装置，还包括由容量补偿单元和相位差检测控制器组成的电抗器本体容量补偿装置；通过相位差检测控制器测量与分析高压变压器初级侧电压与电流的相位差值，配合容量补偿单元的投入、切除，来补偿可控电抗器中因高压变压器初级侧电压与电流的相位差达不到90°，引起的感性输出功率不足部分的偏差，从而保证整个可控电抗器的感性无功功率总容量达到设计要求的真实量值，更加可靠有效地解决电网中对可控电抗器的精准控制和投入使用的合理性。 【EN】The invention discloses a controllable reactor device with a capacity compensation function, which comprises a high-voltage transformer, a load reactive power adjusting device and a reactor body capacity compensation device, wherein the reactor body capacity compensation device consists of a capacity compensation unit and a phase difference detection controller; the phase difference value of the voltage and the current of the primary side of the high-voltage transformer is measured and analyzed through the phase difference detection controller, and the deviation of the part with insufficient inductive output power caused by the fact that the phase difference of the voltage and the current of the primary side of the high-voltage transformer in the controllable reactor does not reach 90 degrees is compensated by matching with the input and the removal of the capacity compensation unit, so that the total inductive reactive power capacity of the whole controllable reactor reaches the real value of the design requirement, and the reasonability of accurate control and input use of the controllable reactor in a power grid is more reliably and effectively solved.
