摘　　要：为搞清楚变耦电抗式可控串补的应用价值,必须对其技术经济性能进行研究。通过理论分析,得出了变耦电抗装置的特性、机理及选用方法,提出变耦电抗式可控串补装置的具体结线并指出其功率调节特性,提出晶闸管开关装置最佳换级控制方法;通过试验证明理论分析的正确性;经功率调节计算,变耦电抗式可控串补较之于TCSC所需主设备容量大幅度减少。初步研究结果表明,变耦电抗式可控串补具有良好的功率调节特性和换级暂态特性,若只用于功率调节,要比TCSC显著降低工程造价。To know application value of thyristor controlled reactance series compensation by adjustable coupling, its fundamental performance must be studied. In the way of analysis theoretically, the characteristic, principle and the opted methods of the adjustable reactance device were obtained, and the material model of thyristor controlled reactance series compensation by adjustable coupling, and its characteristic of power adjusting and the optimal controlling method of tap-changing of the thyristor switches were proposed. Correctness of the theoretical analysis is proved by the test. By power adjusting calculation, thyristor controlled reactance series compensation by adjustable coupling comparing with TCSC, the needed capability of main facilities can be dramatically reduced. The result of primary study indicates that it has good characteristic of power adjusting and tap-changlng transient. When it is only used to adjust power, its engineering cost is much lower than that of TCSC.
