摘要
分析了可控电抗器的电抗特性,指出了选择良好电抗特性的途径;从绕组电势和铁心磁势构成的观点详尽讨论了可控电抗的调节机理,由试验初步证明了其特性机理;大量计算数据表明,将变耦式可控电抗与电容串联用于高压输电线路的容性串联补偿将比可控串补(TCSC)降低更多设备容量。
The characteristic of controlled reactor is analyzed and the approach to select the good reactive characteristic is pointed out. Through the analysis on e.m.f of the winding and the constitution of the m.m.f in the core, the adjustment mechanism of controlled reactance is researched in detail and is tentatively proved by tests. A lot of calculated data show that comparing with the capacity of TCSC the capacity of compensating equipment can be obviously reduced if the thyristor controlled coupling-changeable reactor connected with the capacitor in series is applied to the capacitive series compensation of high voltage transmission line.
