中国石油大庆炼化公司二期30×10~4t/a聚丙烯装置的低压母线采用单母线四段分段运行接线方式,每段低压母线上均安装有低压电容器补偿装置,采用集中补偿方式,每段电容总容量为120kvar,由ABB RVC功率控制器控制四路输出,2组20 kvar并联,2组40 kvar并联。电容补偿装置在电力系统中具有改善电能质量,降低电能损耗的作用,根据设定的功率因数满足低压系统的无功补偿需求。电容补偿装置为静置设备,
Low-voltage busbar of 30 × 10 ~ 4t / a polypropylene plant of PetroChina Daqing Refining & Chemical Co., Ltd. adopts four busbar wiring mode of single busbar, each low-voltage busbar is equipped with low-voltage capacitor compensation device, adopts centralized compensation mode, The total capacity of each segment is 120kvar, which is controlled by ABB RVC power controller with four outputs, two 20kvar parallel and two 40kvar parallel. The capacitor compensation device has the function of improving the power quality and reducing the power loss in the power system, and meets the demand of the reactive power compensation of the low-voltage system according to the set power factor. Capacitor compensation device for the static equipment,
