我国第一套国产可控串联补偿装置——甘肃碧成220kV可控串补在国际上首次实现了固定串补和可控串补混合复用方式,基本串补度达到了50%。统计该装置投运5年来的实际传送电功率与电量数据表明,装置产生了显著的经济效益。故障数据表明,5.2次/a的故障率对于首套装置还需进一步改进;介绍该装置的实际运行维护情况,证明国产固定串补和可控串补装置总体上达到了推广应用要求。
China’s first set of domestic controllable series compensation device - Banshan 220kV controllable series compensation in Gansu for the first time in the world to achieve a fixed string compensation and controllable series complement mixing reuse, the basic series complementarity reached 50%. The actual transmission of electric power and electricity data of the device put into operation for five years shows that the device has produced significant economic benefits. Fault data show that 5.2 times / a failure rate for the first device needs to be further improved; describes the actual operation and maintenance of the device to prove that the domestic fixed series compensation and controllable series compensation device as a whole has reached the popularization and application requirements.
